Why is my AC not cooling?

In the Tampa area, it’s important to keep your home cool and comfortable all year long. Unfortunately, no matter how well you take care of your AC unit, there may come a time when you’re your home starts to feel warmer or more humid than it should.

If you’ve found yourself asking “Why is my AC not cooling my home?” you’re in the right place! Here’s a look at a few of the most common issues you might be dealing with.

1. Clogged Filters

One of the most common AC problems is also the easiest to fix. If you notice that your AC isn’t cooling your home, start your troubleshooting by checking your air filters. Often, these get clogged with pet hair, dirt, pollen, and other debris. This can restrict the airflow, which makes it more difficult for your AC unit to cool your home.

Clogged air filters can also create problems with the outdoor condenser unit and the system’s indoor evaporator coils. Changing your filters at least every three months (and possibly more often if you have pets) will help you avoid this problem.

2. Thermostat Issues

The thermostat in your home measures the indoor temperature and humidity and communicates with your AC unit to maintain your chosen settings. When it feels like your AC isn’t keeping up with your demands, the thermostat could be to blame.

Check to make sure someone in your home didn’t accidentally adjust the temperature or turn the system off. Changing the batteries or rebooting the system may also fix the problem. If not, you may need a replacement.

3. Low Refrigerant

When an AC system doesn’t have enough refrigerant, it will have a hard time keeping your home cool. It’s possible that your system was undercharged during installation, but if you’ve had your system for a while, it’s more likely that you have a leak.

Leaking AC refrigerant is toxic, flammable and harmful to the environment, so you’ll want to call an AC repair specialist right away..

4. Frozen Coils

Your AC unit needs proper airflow to keep the coils warm and working correctly. If the air filters are excessively dirty or air isn’t flowing freely through your ducts, this can cause the coils to freeze. Low refrigerant and other mechanical problems can also cause this issue.

If your AC is running but isn’t pushing cool air to your home, check to see if there is visible ice on your indoor or outdoor coils or a significant amount of condensation around your cooling unit. Often, some simple AC maintenance can fix the problem. You may try changing your air filters and cleaning out your system’s condensate drain pain and lines. If this doesn’t help, it’s time to call an AC repair company.
