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.
