6 Common Sounds That an AC Unit Makes and Their Causes

How can you tell if there is an issue with your air conditioning unit? When your AC makes certain sounds, it is a common indication that there is a problem. Now, different sounds may mean different things. Here are some sounds that an AC unit may make and their possible causes.

1. Buzzing

AC units create vacuum pressure by cycling gas through a condenser coil, which absorbs heat and cools the active ingredients inside the unit. These units are typically very quiet, but they can begin to buzz when they are working.

A buzzing AC unit results in various symptoms, depending on what part of the system is malfunctioning. Most commonly, a buzzing AC unit means that there is something wrong with the internal workings of the unit. More seriously, it could mean that the refrigerant has leaked out or the fan blades aren’t balanced correctly, both of which need immediate attention.

2. Banging

A banging sound from inside your air conditioning unit is most likely caused by a broken or disconnected part. It can be a moving part, such as a crankshaft, piston pin, connecting rod, or rotating fan blade inside the compressor unit. If one of these is broken or disconnected, then you must replace the compressor.

3. Clanking

If you hear loud noises from your AC, the coils in the unit have likely become unbalanced. This can happen if an internal component of the compressor breaks, usually requiring repairs and replacement.

If parts like the internal fan hit other internal components, the problem will only worsen and cause more damage. Not only will loose parts be damaged, but they’ll also knock other parts out.

4. Squealing

Indoor blower motors and outdoor fan motors begin to squeal when they’re failing. You should evaluate the sound’s tone, frequency, and duration to distinguish it from regular squealing.

5. Clicking

When the unit is turned off and then on again, it is normal to hear a clicking sound, but if the unit is turned on and the clicking starts or stops, it can be a sign of a thermostat problem. If the unit is on and the clicking is frequent or perpetual, it could be a sign of a control problem.

However, if you checked and confirmed that it isn’t a thermostat or control problem, it could be an electrical issue. Electrical issues can lead to more costly and even dangerous problems, so if you notice any frequent clicking sounds after turning your unit on, you should address the issue quickly.

6. Humming

Humming noises in air conditioning systems are often the result of loose refrigerant piping or some other parts. This can develop into a bigger problem if it goes ignored. Humming noises in air conditioning systems might also indicate electrical troubles. If there’s loose wiring or a malfunctioning compressor, humming is also likely to occur, and it needs to be investigated.

Conclusion

It is not wise to ignore unusual noises from your air conditioner because they may be signs that your unit has a problem. Ignoring the sound will increase the need for repairs in the future. To properly address the issue, you can have it inspected by a professional.

Nothing matches the feeling of a forceful rush of cold air flowing from your vents on a hot day! However, when your air conditioner’s airflow is insufficient, it becomes tough to keep your house comfortable. Weak airflow is an indication of system problems, and it causes more than just pain — your cooling system may be damaged.

1. Dirty Air Filter

When was the last time you replaced the filter on your air conditioner?

That filter is responsible for removing dust and debris from the air and keeping it out of your equipment and ducts. When the filter becomes overloaded and clogged, it impedes the airflow of your HVAC system, resulting in hot and cold patches and stuffy air. Debris in the device might damage parts as well.

Change your AC filter according to the manufacturer’s instructions and the usage of your system. This might be as often as once a month.

2. Leaky Ducts or Duct Blockage

Air conditioning works hard to keep your home cool, especially in the summer. When you have a leaky duct or duct blockage, you waste energy and can potentially damage your HVAC system.

Leaky ducts are usually small holes or cracks in the ductwork, allowing airflow to escape. Usually, you cannot see these holes, which is why it is important to have your ducts checked by a professional. Air leaks can occur anywhere in the system.

Blockages happen when material is inserted into the duct, like insulation, dryer sheets, rags, or other debris. They can also occur when your air ducts are too small for the size of your HVAC system.

3. Dirty Coils

Your air conditioner may not have enough airflow if the coils are dirty. Dirty coils can shorten the lifespan of your air conditioner and make your home uncomfortable. Dirt and debris cling to coils because of moisture and try to stick to the metal, which causes them to stick together.

A dirty coil can keep your system from functioning properly and should be cleaned immediately. That’s why it’s important to keep your air ducts clean as well.

4. Low Refrigerant Levels

If your air conditioner is using air, but not cooling it effectively, it could be a refrigerant leak. Low refrigerant levels not only lead to system issues, but can also cause serious health problems.

If you suspect a leak, you should call a professional right away. They will be able to find the leak and repair it, or replace your HVAC system if it is beyond repair.

5. Damaged Compressor

Your air conditioner’s compressor is the heart of your cooling system. Compressors are responsible for pumping refrigerant through your HVAC system and turning it into cool air.

A damaged compressor can’t work properly, and your air conditioner will be unable to produce cool air, even if the coils are clean, the air filter is clean, and the ducts are dry. If the compressor is damaged, you may need to replace it.

Conclusion

If you want to reduce your cooling costs, increase comfort and eliminate the five problems discussed above, contact a professional right away. Schedule an appointment to have your HVAC equipment serviced. Proper maintenance ensures that your system continues to work at its highest level so that you will get the most efficient cooling from your AC.

The HVAC system keeps your living or workspace comfortable year-round. It can only be achieved if the system is regularly maintained and cleaned. If you don’t regularly maintain and service your HVAC units, you might find yourself with a busted AC and an even bigger, costlier problem to fix.

Knowing the signs when one needs to have their HVAC system checked can be very helpful for every homeowner. If you need some guidance, here is a list of the signs you should watch out for.

Your HVAC System Produces Weird Noises

Noises from HVAC systems are actually quite common. They are prevalent in systems that have many years under their belts. In older systems, the air ducts can get clogged with debris, causing the system to work harder and make more noise when handling the airflow.

The noise can be a squeak, a whistle, or a groaning sound. It is a warning sign that you should get the system checked.

You Smell Unpleasant Odor Coming From It

You’re probably already familiar with the smell of your HVAC system. If you smell something different, it should be a warning sign. It could be a warning that you need to check your system because something happened. It could mean a leak in your system or a problem with your filter. Don’t take your chances by leaving it for later. Get it checked as soon as possible.

The Heating and Cooling Is Not Like Before

If you feel like you’re not getting the proper heating and cooling temperature as you used to, your system is probably not working as it should. That might not be a sudden occurrence; it could also have been happening for a while before you actually noticed.

HVAC systems work to make your space more comfortable. If something is wrong with your system, it can’t do what it’s meant to do. It could be a sign that you are experiencing a bigger problem.

The System Is Covered With Dust

A system covered with dust and grime is a sign that you need to service and check it. When your system has to work harder and longer to heat or cool your house, it tends to get dusty and grimy.

If it is constantly covered with dust, the system has a problem. It is working too hard, and you should address the issue. If you do not clean the system regularly, the dust can cause the system to break down, and it can even cause health issues if the dust gets mixed with the air you breathe in.

Your Power Consumption Has Spiked

If you notice that your power consumption is higher than usual, it’s likely because your home’s HVAC system is not running properly. Usually, you would expect your consumption to go up during the summer months while using the cooling system. If your consumption is up even when you’re not using your HVAC system too much, this could indicate a problem.

While it’s not likely that your power bill will spike significantly, you can expect your bill to be higher than usual. With an increase in power bills, there is a chance that you need to get a new system.

Conclusion

Like any other system in our home, the HVAC system needs to be well maintained and serviced regularly. If you’re not sure how well your system is running or if it’s in good condition, it’s time you get it checked. These are some warning signs you need to watch out for. If you feel like your system is not working like it should be, make sure you contact a professional for help.

When you get a new air conditioning unit, it can be tempting to try and install it yourself to save money. However, it may be best to get a professional installation instead, as many things can go wrong when you attempt to do it yourself. You can’t guarantee that you, your family, or your property will be safe if you’re not qualified to do a DIY installation.

Here’s what you can expect from a new AC installation & replacement from expert companies.

Compliance with Regulations

When you’re dealing with a large, intricate piece of machinery, it’s best to have a professional on hand. In order to comply with local and national regulations, an AC technician must have the proper credentials and certifications.

You also want to make sure that your installation complies with any regulations in terms of placement and the actual machinery in use. Certain places also have environmental guidelines in place that experts will be familiar with.

Care with AC Parts

You also want to make sure that the machinery is set up properly. Each part of an air conditioner is designed with a specific function in mind. Improper placement or improper function can cause many inconveniences.

At the same time, poor handling can end up damaging the air conditioning system. You don’t want to have broken equipment before you even get started using it. This is especially important if you’re dealing with window-type and ducted air conditioners.

Warranties

It’s always good to have warranties on your side. Buying a unit will usually give you a warrant, but a professional installation will have the added safety of a warranty from the installers.

Plus, the professionals will not do anything that may void your purchase warranty in the first place. This is very helpful in the event that you face certain problems down the line. It also ensures that should an issue arise shortly after installation, you can let the manufacturer know that the handling was done right and it’s most likely a factory defect.

Safety with Installation and Workers

One of the biggest concerns is the safety of the workers and their handling of the machinery. You don’t want to have untrained workers handling the machinery, especially with older or industrial air conditioning units.

You also want to make sure you’re not installing it in a way that puts existing appliances and electrical wiring at risk. Additionally, professionals will have the right equipment to handle everything safely without risking anyone’s wellbeing.

Expertise with Placement and Systems

Air conditioning systems can be very complex, especially if you’re dealing with ducted and split unit systems. You need to know how to properly integrate them into your home and what the placement needs are.

Experts can help you with this. They know the right size of an AC unit to get, where to place it, how to integrate it into the existing system, and how to ventilate the space properly. On top of this, they can help you find a good spot that won’t be intrusive for other parts and features in your home.

Conclusion

An air conditioning installation is an important investment in your home. While it will help you stay cool and comfortable, it can also save you a lot of trouble and bills if installed correctly.
