If your AC unit is running, but not cooling your space, your unit might need a repair. Here are 5 reasons why your AC unit isn’t functioning properly.

Thermostat Isn’t Set Properly

Before you freak out about your AC unit not working, make sure you check the thermostat. First things first, make sure that the thermostat is set to “cool.” Then, check the temperature setting to see if anyone made an adjustment. If your thermostat is set to “off,” turn on the heat first before setting it to cool. Check your registers to see if cool air is blowing out now.

Dirty Air Filter

Many AC units have air filters in or around the indoor air handler unit. These filters catch dirt, dust, and other airborne particles. It prevents these particles from entering the unit and keeps the components inside the system clean. This, in return, will keep the air in your home clean as well. However, if you have a dirty air filter, then the airborne particles will block airflow and reduce cooling to your home. If the air filter isn’t changed, it can even shut off your system completely.

Refrigerant Leak

In order for your AC unit to cool, you need a refrigerant. It is a chemical that flows through the system’s indoor and outdoor coil. It changes from liquid to gaseous form and draws heat energy and humidity from the indoor air and releases it outdoors. If you have a refrigerant leak, then your AC unit may not cool your home.

Condenser Unit Is Blocked

Most AC units come with an outdoor condenser unit. There is a large outdoor coil that wraps around the outside of the unit. The coil includes a series of metal fins that are tightly together. If your AC unit is running but not cooling, the condenser coil might be clogged or blocked. Airborne debris, grass, and dirt can build up within the fins, which clogs the coil as a result.

This leads to less energy efficiency and a lack of cool air from the registers. You can try to clean the coil by vacuuming it with a brush attachment. However, if your system still doesn’t cool, get in touch with Ellis Air Conditioning and Heating.

Heat Pump Is Damaged

A heat pump is like an air conditioner, but it contains the ability to cool and heat your property. It works similarly to a condenser unit, and it can also get clogged by dirt, debris, grass, etc.
