10 Common HVAC Repairs Homeowners Should Be Prepared For

HVAC systems are essential in every home, providing comfort and regulating indoor temperatures. However, like any other mechanical system, HVAC units are prone to wear and tear, which can lead to breakdowns and malfunctions.

As a homeowner, it’s essential to understand the most common HVAC repairs you may encounter and how to deal with them. This article will discuss the seven most common HVAC repairs you should be prepared for.

1. Dirty Air Filters

Dirty air filters are one of the most common HVAC problems homeowners face. Air filters are designed to trap dirt, dust, and other particles that circulate in the air. When the filters get clogged, they restrict airflow, causing the system to work harder to maintain the desired temperature.

This can lead to higher energy bills, poor indoor air quality, and even system failure. To avoid this, homeowners should change their air filters regularly, preferably every three months.

2. Refrigerant Leaks

Refrigerant leaks are another common HVAC problem. Refrigerant is vital in air conditioning systems as it absorbs heat from the air and releases it outside.

When there’s a leak, the system won’t be able to cool air as efficiently, leading to poor performance and increased energy bills. If you suspect a refrigerant leak, you must call a professional HVAC contractor to fix the issue immediately.

3. Thermostat Issues

Thermostat issues are also common HVAC problems. A malfunctioning thermostat can cause the system to run continuously, leading to higher energy bills and wear and tear. It can also cause the system to turn on and off frequently, leading to poor comfort levels.

If you notice that your thermostat is not working correctly, it’s essential to call a professional HVAC technician to diagnose and fix the issue.

4. Faulty Capacitors

Capacitors are electrical components that help start the HVAC system’s motors. The system won’t be able to start when they fail, leading to a complete breakdown.

If you hear a humming sound from your HVAC system, but it doesn’t start, it’s likely a faulty capacitor. It’s essential to call an HVAC technician to replace the capacitor before it causes further damage to the system.

5. Dirty Condenser Coils

Condenser coils are located outside the home and release heat from the refrigerant. When they get dirty, they can’t release heat efficiently, leading to poor system performance and higher energy bills. Regular cleaning of the condenser coils can help prevent this problem.

6. Clogged Drain Lines

Air conditioning systems produce condensation, which needs to drain away from the system. The condensation can’t drain away when the drain lines get clogged, leading to water damage and mold growth. If you notice water pooling around your HVAC system, it’s essential to call an HVAC technician to unclog the drain lines.

7. Dirty Evaporator Coils

Evaporator coils are located inside the home and are responsible for cooling the air. When they get dirty, they can’t cool the air efficiently, leading to poor comfort levels and higher energy bills. Regular cleaning of the evaporator coils can help prevent this problem.

Key Takeaways on HVAC Repairs Homeowners Should Prepare For

HVAC systems are essential in every home, and it’s essential to understand the most common HVAC repairs you may encounter. These seven common HVAC repairs can be easily prevented with regular maintenance and proper care, from dirty air filters to clogged drain lines.

5 Warning Signs That Your Heating System Requires Service

For optimal performance throughout their lifetimes, heating, ventilation, and air conditioning systems always need to be serviced and maintained correctly. During the short, harsh months of winter, the comfort of everyone in your home depends on the efficiency of your home’s heating system.

You should constantly ensure that your heating system, be it a furnace, boiler, or heat pump is operating correctly. This system will keep your home warm while ensuring your family’s safety. The occurrence of a mechanical problem in the dead of winter can feel like something out of a nightmare. Read on to learn about the five warning signs that your heating system requires servicing.

1. Heating Bills Have Gone up Significantly

If you’ve seen a substantial increase in your heating bills, it’s a sign that you need to arrange a heater repair. One possibility is that your heating system is no longer operating as efficiently as it once did. It means that it’s using more energy to heat your home, and that’s reflected in your higher bills.

2. Your Home Isn’t as Warm as It Used to Be

If you’ve noticed that your home isn’t as warm as it used to be, the first thing you should do is check the filter in your furnace. If the filter in your furnace is dirty, it may limit air passage, causing your furnace to work harder than it should. Replacing a dirty furnace filter with a clean one can improve your furnace’s efficiency and heat output.

3. Chilly Spots All Over Your Home

If you are like most people, you probably don’t give much thought to the heating system in your home until it begins to act erratically. If, on the other hand, you find that different rooms in your house have varying degrees of warmth, your heating system needs maintenance.

Repairs to the heating system should be performed as quickly as possible, regardless of the cause. Ignoring the issue will not make it go away; instead, it will only make it worse and may finally result in the total collapse of the system.

4. You See Visible Damage on Your Furnace

If you see any visible damage on your furnace, it’s a sign that you need to schedule a heating repair as soon as possible. Regardless of the severity of the damage, it’s essential to have it repaired quickly. Doing so can prevent further damage to your furnace and keep your home safe and comfortable.

5. There’s a Strange Smell Coming From Your Furnace

If you notice a peculiar smell coming from your furnace, it’s a sign that you must schedule a heating repair. It is because the smell likely comes from a burning wire or another problem with the furnace.

If you smell gas, it’s important to evacuate the area immediately and call your gas company. Do not try to fix the problem yourself, as this could be very dangerous. Once the gas company has shut off the gas, you can call a heating repair company to come and take a look at your furnace.


Suppose your heating system is not operating as it should contact a heating repair professional as soon as possible. A malfunctioning heating system can result in several issues, including making your home unpleasant to live in, increasing your energy bills, and creating a potential risk to your safety. If you schedule a repair as soon as possible, to avoid these problems and keep your home safe and warm.

Common Heating Repair Problems to Be Aware Of

As the weather gets colder, your heating system will start to work overtime to keep your Colorado home warm and comfortable. However, heating systems can develop problems over time, like all mechanical systems.

Knowing the most common heating repair problems can help you troubleshoot issues with your system and get it back up and running as quickly as possible.

In this post, we will discuss some of the most common heating repair problems and what you can try to fix them:

1. Clogged and Dirty Air Filters

One of the most common heating repair problems is clogged or dirty air filters. When your air filter is clogged, it restricts the airflow to your furnace, making it work harder to heat your home. A clogged air filter could also cause your furnace to overheat, damaging the heat exchanger.

To prevent these problems, checking and cleaning your air filter regularly is essential. You should also check your furnace’s air filter monthly and replace it if it’s dirty.

2. Issues with the Thermostat

If your thermostat is not working properly, it can cause your heating system not to work at all or not to work as efficiently as it should. There are a few things that you can do to troubleshoot a problem with your thermostat:

First, ensure that the batteries in your thermostat are fresh. If the batteries are old, they may not provide enough power to the thermostat, causing malfunction.

Next, check if the thermostat is set to the correct temperature. If it is not, adjust it until it is.

If the thermostat is still not working the way it should, you may need to replace it. You can buy a new thermostat at most hardware stores.

3. Burning Smells

If you notice a burning smell emanating from your furnace, it’s vital to take action immediately. This usually indicates that something is overheating and could potentially catch fire.

If you can, turn off the power to the furnace and call a heating repair technician. They will be able to diagnose the issue and make the necessary repairs.

Sometimes, the burning smell may be due to a dirty furnace filter. If this is the case, you can replace the filter yourself. However, if you’re unsure what the problem is, it’s always best to call a professional.

4. Strange Noises

If you can hear strange noises from your furnace, it’s important to have it checked out by a heating repair technician. These noises could be an indication of a serious problem, such as a cracked heat exchanger.

A heating repair technician can diagnose the problem and make the necessary repairs. In some cases, the heat exchanger may need to be replaced.

5. Frequent Cycling

If your heating system is cycling more frequently than usual, you should first check your filter. If it is dirty, replace it with a new one. If your thermostat is too low, you can raise it a few degrees. If your furnace is a little too small for your home, you may need to upgrade to a larger unit.

If you are still having problems with frequent cycling, you should call a heating repair technician. They will be able to diagnose the concern and make the necessary repairs.


These are just five of the most common heating repair problems you should know about. It is highly recommended that you seek the help of a pro to ensure that your heating problem is addressed. There are trusted professionals that offer affordable heating services, so don’t put off the repair, or the problem could get even worse.

heat pump repair Company in Castle Rock Colorado

4 Signs You Need Heat Pump Repair

Your heat pump is essential to your Castle Rock home or business’ heating system. Most of the time, it runs smoothly, and we don’t think about it. We only really pay attention to it when something goes wrong. However, when this happens, it can be costly to fix. Often, we can avoid needing a professional if we catch the problem early.

Take the time to inspect your heat pump regularly (the changing seasons and weather conditions in Castle Rock, Colorado require it) and look out for the following signs that you might need heat pump repair:

1. Restricted Airflow

If you start to notice that your home or business is not heating as well as it used to, then you should look at the coils inside your unit. If you see that they are clogged with debris, you will need to clean them. If the debris is a long-term problem, you might need to have a professional clean the unit and check it over.

Here are some common heat pump airflow issues:

  • Clogged Air Filters — A clogged filter restricts air flow and could lead to reduced energy efficiency or the unit shutting down completely. Clean or replace the filter if it is excessively dirty.
  • Wrong Fan Settings — Make sure your fan setting is set to “on” or “auto” instead of “off”, as this will ensure proper air movement within the system.
  • Obstructed Vents — Ensure there are no obstructions blocking exterior vents, such as leaves, twigs, dirt, etc., that can limit the amount of air coming into and out of the unit.
  • Malfunctioning Parts — Check for worn belts and other malfunctioning parts that can prevent full air flow from moving through the system properly.
  • Poorly Insulated Ducts — If the ductwork running through your home isn’t properly insulated, heat can escape and cause reduced airflow throughout the unit.

If you have animals or small children in your home, you need to be aware that they love to play in vents and can often clog them up with debris. This will have the same effect as if there was a blockage in the coils, as the airflow will be restricted, and the unit will not perform as well as it should.

2. Inefficient Operation

If your heat pump is not working well, you must check to see if the coils are dirty. They can become dirty for several reasons, such as dust, pet hair, and dirt. A professional can clean your heat pump and check that it is working as it should. They will also be able to tell you what you can do to improve the airflow and the efficiency of your heat pump.

If your thermostat does not work properly, you will need to see if it is the thermostat itself or the wiring. Again, a professional can check your unit and repair the problem.

3. Ice on the Coils

This is a more serious problem. In extreme cases, the pipes inside the heat pump can burst, and you will need to replace the entire unit. However, if the pipes are just leaking, then you might be able to have them repaired. When your heat pump runs, there should be no frost or ice on the coils. If you see this, then you need to have it checked out. If you have noticed ice building up on the coils of your heat pump HVAC unit, it is important to take immediate steps to prevent further damage. While there are many potential causes for this issue, here are a few tips for how to handle it:

  • Check Your Air Filters — A clogged or dirty air filter not only restricts airflow but also can cause frost buildup and blockage of the evaporator coil. Make sure your filters are clean and in good condition.
  • Adjust Your Fan Settings — Make sure the fan settings on your unit are set correctly; if it is set to “off”, you may be restricting airflow throughout the system and causing ice buildup.
  • Clean Any Obstructions — Look for any debris such as leaves, twigs or dirt that is blocking vents and preventing proper air movement into and out of the unit.
  • Check Temperature Sensors — If your temperature sensors aren’t working properly, they may be sending incorrect signals to your thermostat and causing frost buildup in certain areas.
  • Inspect Refrigerant Lines — If refrigerant lines become blocked, restricted or punctured due to age or improper installation, it can lead to reduced air flow in your system, resulting in colder temperatures at the evaporator coil which can cause frost buildup and icing issues over time.

Taking proactive steps like checking filters, adjusting fan settings and cleaning obstructions will help ensure that your system is running efficiently with adequate airflow throughout which helps prevent ice build up on the evaporator coil in future instances.

4. Noisy

If your heat pump is making noises or vibrating, it might break down. You may be able to have it repaired, but it will definitely be better to have it replaced before it does break.

Here are some reasons you may encounter a noisy heat pump unit, and areas to check:

  • Loose Parts — Parts such as compressors, fans, and belts that are loose or misaligned can cause noise and vibration within the system.
  • Clogged Filters — A dirty filter restricts air flow, which may cause rattling noises due to poor air movement. Clean or replace the filter if it is dirty.
  • Debris Blockage — Debris such as leaves or twigs trapped in the fan blades can create a rattling noise when running or moving through the unit.
  • Condensate Line Blockage — If your condensate line isn’t draining properly, you may hear gurgling sounds coming from your unit due to water build up in the pipes.
  • Blower Motor Issues — If there is an issue with the blower motor it may cause loud clanking or banging noises to come from your heat pump HVAC unit.

If you notice any of the above problems, you should see if you can fix them yourself. You will not need to call in a professional if you can. If you can’t, then you should definitely hire a professional to look at your unit.


These are all signs you will need to repair your heat pump and call in a professional. If you live in a climate where you do not need your air conditioner or heat pump to work all year round, consider renting it rather than buying it. They are expensive to purchase and maintain, and you will likely only need them for half a year.

When Must Homeowners Consider Hiring HVAC Cleaning Services?

Heating and cooling machines are vital in every home. They moderate indoor air quality while ensuring the temperature stays balanced within the property. However, like other machines, HVAC systems may also experience wear and tear over time.

Therefore, scheduling a maintenance service or repair work for HVAC systems should happen at least once a year. But there are instances when they may need more than the scheduled maintenance. But when should homeowners consider hiring HVAC cleaning services?

Producing Weird Noises

One of the most common signs that your HVAC system needs repair is when it produces unusual noises. The most common sounds you will hear are squealing, grinding, or banging noises. These sounds usually signal that the system’s components are starting to wear out. Another common sign that your HVAC system needs repair is when it produces clicking or hissing noises. Here are examples of weird noises your HVAC system could be making:

  • Buzzing — Buzzing sounds coming from an HVAC system could be caused by a dirty filter, an unbalanced fan motor, or even lint buildup in the ducts.
  • Clicking — When your system is clicking, it may mean there are loose components inside the unit that need to be tightened.
  • Rattling — Rattling noises can signify poor airflow due to a clogged air filter or blocked vents. Alternatively, the rattling could indicate loose parts within the system’s structure.
  • Squealing — If you hear squeaking coming from your HVAC system, it may mean one of its internal components is out of alignment, like the belt that drives the blower motor needs replacing.
  • Whistling – A whistling noise usually indicates a duct is leaking and should be sealed or replaced as soon as possible to restore peak energy efficiency and avoid wasting money on utility bills.

These sounds indicate an issue with the system’s air ducts. If you hear any of these sounds coming from your HVAC system, it is best to call a professional to have the system checked.

Emitting Unpleasant Odor

Another common sign that your HVAC system needs repair is when it emits an unpleasant odor. Several issues, such as a dirty air filter or a clogged air duct, can cause it. If you notice an unpleasant smell coming from your HVAC system, it is best to call a professional.

If you notice a musty smell coming from your HVAC system, it could signify that the system’s evaporator coil is dirty. A dirty evaporator coil can cause the system to emit a musty smell. Leaving it unchecked can lead to more severe HVAC system problems in the future.

Common unpleasant odors your HVAC system could be emitting include:

  • Musty — If you smell a musty odor, it could indicate the presence of mold or mildew in your ventilation system.
  • Dusty — Dusty odors usually occur when air filters become clogged with debris and should be replaced as soon as possible.
  • Burning — An unpleasant burning smell could signify an electrical component inside the unit is overheating and needs to be inspected immediately to avoid potential fires or shocks.
  • Fishy — Fishy smells are caused by obstructed condensation lines and can lead to water damage if not diagnosed promptly.
  • Acrid – Acrid smells indicate a gas leak in the system and should be addressed right away for safety reasons.

Not Heating or Cooling Properly

One of the most common issues homeowners experience with their HVAC systems is improper heating or cooling. If your HVAC system is not providing the desired temperature in your home, it is a sign that it needs to be repaired or replaced.

One of the most common issues that can cause your HVAC system not to heat or cool properly is a clogged air filter. A dirty air filter can restrict the airflow in the system, which can cause it to overheat. A clogged air filter also causes the system to work harder, causing higher energy bills.

Dust Accumulation

If your home has a lot of dust, it could be a sign that your HVAC system is not functioning correctly. A clogged air filter can cause the system to work harder and blow dust into your home. As a result, the entire household may develop allergies, causing colds and coughing.

Another possible reason for dust accumulation could be a leak in your ductwork. The ductwork can develop leaks over time, allowing dust, pollen, and other allergens to enter your home. Instead of cleaning the air, the HVAC system will only make the air dirtier than it already is.

High Energy Bills

If your energy bills are higher than usual, technicians must fix your HVAC system. It could be due to a clogged air filter, a broken blower motor, or leaky ductwork. It is essential to have a professional inspect your HVAC system to determine the cause of the problem and make the necessary repairs.

It’s no secret that keeping your home comfortable during the summer and winter months can take a toll on your energy bills. But, did you know that having your HVAC system regularly inspected and cleaned can help lower those costs?

An efficiently running HVAC system will not only save money by reducing strain on the unit, but also by improving air quality throughout the home. During an inspection and cleaning, a technician will check for any malfunctioning parts, as well as inspect filters, fans, coils, and ductwork for dirt or debris.

A dirty filter can cause poor air flow throughout the system, making it difficult for the unit to regulate temperature evenly. With less air passing through it, the motor has to work harder to deliver optimal climate control — leading to higher energy costs. In addition to this, clogged filters reduce air quality by trapping dust particles in throat of the ventilation system.

Regular inspections and cleanings are essential for any healthy HVAC system — even if nothing seems amiss! Keeping up-to-date with maintenance helps prevent large repair costs down the line due to diminished performance or equipment failure. Not only that, but regular checkups ensure optimum efficiency is maintained so you won’t be paying more than necessary on costly energy bills each month. So don’t wait any longer — call an expert today!

Conclusion when to Hire HVAC Cleaning Services for Homeowners

If you have noticed any of these signs, it is time to call a professional HVAC contractor to inspect your system. Leaving the signs untreated or unchecked can lead to more severe problems. But having them checked earlier is still cheaper than replacing the entire machine.

CG Heating & Cooling offers furnace services in Castle Rock, helping homeowners maintain their heating and cooling machines to last longer than expected.

Why You Should Have Your HVAC System Inspected Regularly

Having an HVAC system inspected regularly can save you time and money in the long run. A regular HVAC inspection ensures that your system is functioning optimally and runs at peak efficiency while keeping energy costs low. By performing a thorough inspection prior to any major repairs or installations, your HVAC technician will be able to tell you if there are any issues that need to be addressed in order to keep your system running efficiently.

Additionally, having an HVAC system inspected regularly helps to identify potential problems before they become bigger – and costlier – issues. Identifying minor problems early on allows for more cost-effective solutions and helps extend the life of your heating and cooling equipment. Regularly scheduled maintenance also serves as a preventative measure against more severe malfunctions down the road, ensuring your system runs correctly throughout its entire lifespan.

Most importantly, having a routine inspection guarantees that the air quality in your home is kept safe. An HVAC technician can check for dust and other allergens that may have built up over time, helping to improve air quality. Improved indoor air quality will decrease asthma symptoms and allergies, providing health benefits for all family members in the household. In addition to this, regular maintenance of your HVAC unit can help reduce carbon dioxide emissions which results in environmental benefits as well.

Is An HVAC System Inspection Necessary?

An HVAC system inspection is a necessary part of keeping your family safe and comfortable. Regular inspections help to diagnose any existing issues early on, enabling you to address them before they become more serious and costly repairs. By regularly having your HVAC system inspected, you can ensure it’s running efficiently while minimizing expensive repairs or replacements down the road.

It’s important to note that regular maintenance services such as changing filters and checking temperatures are not enough to properly inspect an entire HVAC system. Only a licensed technician can provide a comprehensive inspection that covers all aspects of the system, including the ductwork, electrical connections, and safety components which are difficult for homeowners to check on their own. Furthermore, state licensing boards require professionally completed inspections for certain types of equipment in order for them to stay in operation, so there may be legal implications if these inspections are not done properly or timely.

Overall, having an HVAC system inspected is critical for keeping your home safe and comfortable for yourself and your family. A complete annual inspection helps identify issues with your heating or cooling system before they become major problems as well as making sure it’s working as efficiently as possible while keeping energy costs low. In addition, a professional technician can provide recommendations on how to keep your unit functioning at its best without breaking the bank.

How Often Should I Get an HVAC System Inspection?

It is recommended that homeowners have their HVAC system inspected once a year. This allows for any potential issues to be identified and addressed in time to prevent major damage or pricey repairs. A professional HVAC technician should be able to detect any problems before they become more serious and costly, saving you time and money in the end.

In addition, having your HVAC system inspected regularly helps ensure it is running optimally, allowing for the most efficient use of energy while keeping energy costs low. This will help you save money on bills in the long run. Also, an annual inspection can check for dust, allergens, and other contaminants which can build up over time, helping keep air quality levels safe for your family.

It’s important to note that if your area experiences extreme weather conditions regularly (such as hot summers or cold winters) then it may be beneficial to perform HVAC inspections more than once a year as these conditions can accelerate wear-and-tear of the system components. However, at least one comprehensive inspection per year with a certified technician is necessary to keep your system running efficiently and safely throughout its entire lifespan.

What Does A Professional HVAC System Inspection Entail?

A professional HVAC system inspection entails a thorough examination of the entire HVAC system. This includes checking various components such as the electrical connections, ductwork, and safety mechanisms to ensure that all are working correctly without any potential risks. A licensed technician will also check for problems with airflow and temperatures in each room to ensure balanced temperature levels throughout your home.

In addition, a professional inspection will check for dust, allergens, and other contaminants that can build up over time and lead to poor air quality. The technician can provide recommendations on how to address these issues while keeping your family safe from any health hazards they may pose.

Finally, once the inspection is complete, the technician should provide you with a detailed report of their findings which includes information about any potentially hazardous conditions or areas where improvements can be made to increase energy efficiency or safety. Overall, this comprehensive inspection helps protect your family’s comfort and safety while ensuring your HVAC system is running as smoothly as possible.

The Benefits of Having Your HVAC System Inspected

Having your HVAC system inspected is beneficial for several reasons. First, an inspection can identify potential problems before they become more serious and costly, saving you time and money in the end. In addition, it can help ensure that your system is running efficiently and using energy properly. This will not only save you money on bills throughout the year but also make sure that you are getting the most out of your HVAC system.

Inspections can also check for dust, allergens, or other contaminants which may have built up over time, helping to keep air quality levels safe for your family. Furthermore, having an inspection done regularly allows technicians to catch any potentially hazardous conditions before they become dangerous. Finally, inspections give you peace of mind knowing that your HVAC system is operating safely and optimally at all times.

Overall, having regular HVAC system inspections is beneficial both short-term and long-term as they help save time and money while keeping your family’s comfort level high. Proper maintenance and upkeep with professional inspections are key to ensuring a long lifespan for any HVAC system.

Conclusion on Having Your HVAC System Inspected Regularly

Regular HVAC system inspections are an important part of any homeowner’s maintenance routine. Not only do they help keep your family safe and healthy, but they also save time and money by catching potential problems before they become more serious. With a regular inspection plan, you can be sure that your HVAC system is operating at peak efficiency and meeting all safety standards. Ultimately, having your HVAC system inspected regularly will give you the peace of mind to know that you and your family are comfortable and secure in your home.

Furnace Repair in Castle Rock

5 Noises Coming from Your Furnace and How to Fix Them

Various issues can make your furnace create loud noises. Scraping, banging, whistling, and popping can indicate a loose part, a cracked heat exchanger, or dirty gas burners. To prevent a gas leak from endangering your home and family, here are five loud furnace sounds you should know and how to fix them:

1. Scraping

If you hear a scraping noise from your furnace, it’s important to take note and investigate the source of the noise. It could signify that your furnace’s ball bearings are worn out or that the blower wheel has become loose. Either way, it’s best to turn off the heat and call a certified HVAC professional. Doing so can prevent further damage to your furnace and keep your home heated safely and efficiently.

2. Banging

If your furnace is making a loud booming or banging noise, it may be caused by a small gas explosion during an ignition delay. Gas can build up in the combustion chamber when the gas burners in the furnace do not ignite on time. If the gas burners are not igniting efficiently, this may indicate a clog or a gas pressure problem. Do not attempt to fix the gas burner without a licensed technician, as disassembling the heat exchanger or burners can cause a gas leak in your house.

3. Popping

The blower motor in your furnace turns on and begins circulating warm air throughout the ductwork in your home. If you hear a loud popping noise when the furnace is first turned on, it’s likely due to the expansion of the metal ductwork as the warm air comes into contact with it. Another possible source of the noise could be the gas burners in your furnace. Over time, sediment can build up on the burners; if this debris isn’t removed, a large amount of gas can collect and cause holes in the heat exchanger.

4. Rattling and Rumbling

If you notice that your furnace is vibrating, it is important to have a professional inspect it. Loose parts can cause vibration and, if left unchecked, can break other components in your furnace. A certified professional will have the tools and equipment necessary to fix the problem.

5. Shrieking

If your furnace starts making a high-pitched squealing noise, there is a problem with the motor. The most likely problem is a damaged belt. If you catch the problem early, it is easy to fix with the right tools and equipment. However, if you don’t catch it early, the problem can become much worse. Therefore, it is important to call a licensed contractor to repair the belt as soon as possible.


There are many different types of furnace noises, and each one can indicate a different problem. If your furnace is making any strange noises, it’s important to have a professional take a look at it to diagnose the problem and find the best solution. With some basic troubleshooting and knowledge of how your furnace works, you can often fix small problems yourself. However, it’s always best to call a professional for bigger issues.

heat pump installation services Castle Rock Colorado

Why You Should Consider Heat Pump Installation

Every homeowner understands that comfort and energy efficiency are two factors you need for your home. After all, nothing beats a house that you can return to and relax, as well as one that doesn’t cost a fortune to maintain.

Installing a heat pump is one of the many things you can do to improve your house’s comfort and energy efficiency. If you didn’t know, a heat pump is one of the modern market’s most effective HVAC systems. It is used to regulate the temperature of your house by either drawing heat from or releasing heat to the outdoors.

Most people are hesitant to install heat pumps in their homes because they are unfamiliar with the technology. However, there are many reasons you should think about heat pump installation.

Here’s why heat pumps are becoming more and more common in modern homes:

1. Cost-Effective Heating and Cooling

You might think that heat pump installation is expensive, especially since the initial investment is pretty high. But when you think about the long-term benefits, you’ll realize it’s worth every penny. Not only will you have a comfortable home all year round, but you’ll also save a lot of money on your energy bills.

For one, heat pumps provide heating and cooling, saving installation costs since you won’t need separate units for both purposes. Additionally, heat pumps are energy-efficient because they work by transferring heat energy from one place to another. This makes them use less energy than conventional heating and cooling systems.

2. Low Maintenance Costs

Most homeowners don’t like going through the trouble of maintaining appliances because it takes time and money. However, with heat pumps, there’s nothing to worry about this problem because they require low maintenance.

One reason heat pumps don’t need regular maintenance is that they don’t have a lot of moving parts. This means there’s less chance for wear and tear, and you won’t have to replace them as often as other appliances. Additionally, heat pumps are designed to be durable, so you won’t have to worry about them breaking down soon.

3. Environment-Friendly

Heat pumps are the best choice if you’re searching for an appliance that won’t hurt the environment. Unlike other heating and cooling systems that use fossil fuels, heat pumps only use electricity. As a result, they don’t produce harmful emissions that can damage the ozone layer.

Heat pumps can also help you save water because they need little of it to function properly. In fact, some heat pumps don’t even use water at all. This means you won’t have to worry about your water bill going up when using them.

4. Enhanced Air Quality

Your overall health might be significantly impacted by indoor air quality. That’s why ensuring that your home has a quality air filtration system is important.

5 Common Reasons Behind a Furnace Overheating & What to Do

Overheating furnaces can be an issue, especially in the winter. When a furnace overheats, the entire system may shut down unexpectedly at any time. Worse, you may have difficulty restarting the furnace, leaving you utterly stuck in the bitter cold.

There are various early warning indications when a furnace is overheating. The most prevalent symptoms are a burning odor from the vents and strange noises originating from the furnace unit. If these are persistent symptoms, you should contact HVAC professionals as soon as possible since an overheated furnace can be fatal.

As a homeowner, you should look into why your heater is overheating. Once you’ve identified the underlying causes, you may take proactive actions to prevent your furnace from overheating again. The following are five probable causes of furnace overheating and how to resolve them:

1. Restricted Airflow

The most common cause of a furnace overheating is restricted airflow. When hot air gets trapped inside the furnace, it will start to overheat and eventually shut down. The first step to prevent this from happening is to check the vents and make sure they are clear of any obstacles. Remove any furniture or other objects that may be blocking the vents and preventing hot air from circulating.

2. Old Age

Another reason your furnace may be overheating is that it’s simply getting old. Over time, furnaces will start to break down and become less efficient. If your furnace is more than ten years old, it may be time to invest in a new one.

3. The Inner Workings of Your Furnace Have Malfunctioned

If the inner workings of your furnace have malfunctioned, it could cause the entire system to overheat. This is usually due to a problem with the blower motor or the heat exchanger. If you suspect this is the problem, it’s best to call in a professional to take a look.

4. Short Cycling

Short cycling is when your furnace turns on and off more frequently than normal. This can happen for various reasons, but the most common is an issue with the thermostat. If your thermostat is set too low, it will cause the furnace to turn on and off more frequently in an attempt to reach the desired temperature. This puts a lot of strain on the furnace and can eventually lead to overheating.

5. Dirty Internal Components

Another common cause of furnace overheating is dirty internal components. Over time, dirt and dust will build up inside the furnace, making it less efficient and more likely to overheat. To prevent this from happening, it’s important to regularly clean the furnace and make sure all the internal components are free of debris.

Conclusion on Reasons a Furnace can Overheat

If you’re experiencing any of the symptoms of an overheating furnace, it’s important to take action immediately. By taking proactive steps to fix the problem, you can prevent your furnace from shutting down and leaving you stranded in the cold.

5 Common Reasons Why Your Furnace Has a Funny Smell

5 Common Reasons Why Your Furnace Has a Funny Smell

If you smell something strange coming from your furnace, it could be trouble, or it could be nothing at all. Here are the most common smells and what you should do about them.

1. Musty Furnace Smells

When you turn on your furnace in the fall, you might notice that it smells. In most cases, this indicates that mold is growing in your ductwork or on the air conditioning coil located above your furnace. Unfortunately, you’ll need to hire a furnace professional for an inspection and cleaning. If there is no mold on the A/C coil, it is time to get your ducts cleaned since that is where the mold is forming.

2. Furnace Smells Like Rotten Eggs

Once again, it might mean nothing, but it might also mean you have a serious condition that requires immediate attention.

If you notice a rotten egg or sewer smell, then there’s a chance your furnace has a clogged oil burner or a clogged burner tube. If you’re not familiar with the term, a burner tube is the pipe that takes the gas from the burner to the gas valve and then to the main part of the furnace.

If the burner tube isn’t clear, the gas can’t travel to the valve, so that it will smell like rotten eggs or a sewer. If you smell that, it’s time to call in a furnace technician for an inspection. In some cases, the furnace may need to be replaced.

3. Burning Smell

If you notice a burning smell, then it may mean that the furnace is overheating. An overheating furnace can damage the motor, the blower, and the air conditioner. If you notice a burning smell, it’s time to shut the furnace off and call a furnace technician.

If you have to leave the house because of the burning smell, make sure you don’t leave an item on that needs to be turned off. For example, if you have a security system, make sure it’s turned off before you leave. If you don’t, you may come home to a burglar and a security system that’s going off. Also, make sure you turn off the carbon monoxide detector.

4. Dusty Smell

Don’t be alarmed if you start your furnace at the beginning of the heating season and smell dust. Throughout the summer, dust has accumulated on the interior of your furnace. The components that get heated, burn off the dust, and produce that noxious odor. It won’t be around for long.

5. Burning Plastic

If your furnace smells like burnt plastic or rubber, it might be due to an electrical fault. This burning smell can be given off by melting plastic wire casing, which is a safety issue. If you detect a melted plastic odor, switch off your heating system immediately and contact a specialist.


If your furnace smells, don’t just try to ignore the odor. If you ignore it, it could lead to bigger problems. To prevent spending more in the future, call a professional if you have an unusual odor coming from your furnace.
