If your air conditioner does not seem to be cooling your house down, this could be a big problem- especially during hot summers. Luckily there are usually some common causes that can help solve this issue. Nelson Comfort is here to educate you on 4 common reasons your HVAC system is not cooling your home properly.

Your Air Filter is Dirty – An Easy Fix for Your HVAC System

You should be frequently checking your air filter. This is a very common problem when it comes to your house not cooling properly. First you should check your units air filter. If it is dirty you will need to replace it. A dirty filter can reduce air flow, meaning your HVAC system will struggle to circulate the cool air into your home. Less air flow means less cool air coming into your home since your HVAC system will be having to take longer to do its job. Make sure you clean or replace your filters when needed.

Your Outside Unit is Not Clean

Another common problem we see here at Nelson is homeowners who have dirty outside units. If your condenser is not clean or has a lot of debris blocking it then it can’t get rid of the heat coming out of your house as easily. If this occurs, your home will not be cooled properly since the heat is not being expelled properly. This could be a major cause as to why your home is not being cooled to the full extent it should be. Our suggestion is to keep your condenser clean and free of debris such as weeds, leaves, or any plants that could be blocking it.

Your Refrigerant is Low

A main cause for HVAC problems can stem from your refrigerant being too low. Refrigerant is necessary to absorb the heat and produce cool air. When you are running low, there won’t be enough to cool the air. Refrigerant is usually recirculated through the system so if yours is low you must check for refrigerant leaks. This type of leak must be fixed by a professional. Some signs would be ice buildup on your unit and your AC not cooling your home. If you spot either of these signs please call Nelson Comfort. We will come help you fix the leak, so your home is able to cool you down and keep you comfortable.

Your Home is Drafty – How does this affect your HVAC System?

Some homes, especially homes that are older can have leaks. These leaks can be anywhere from doorways to windows. With these leaks comes the hot air that is keeping your house from cooling down. If your home tends to leak a lot of air, it could be leaking it faster than your HVAC unit is able to prepare cool air. For problems like this we recommend blocking drafty windows, changing your door sweeps, and searching for duct issues. By doing so you can help prevent these leaks in your home and have a cooler home.
