Change the Air Filter

When your HVAC unit stops cooling your home, the first thing you should do is check the air filter.

Air filters can easily become clogged with dust, dirt, and other types of pollutants, preventing proper airflow. Fortunately, air filters are inexpensive and easy to replace. Thus you should keep several on hand so that a dirty one can be replaced as needed.

Check Your Thermostat

If your thermostat is set at a cool temperature but your house remains warm, this could be a sign of problems. Keep in mind that thermostats aren’t designed to last forever. When it’s time for a replacement, a quality digital thermostat can be purchased at any local home improvement store.

Clear Debris Away From the AC Unit

It’s common for debris such as tree branches, leaves, dirt, or snow to collect on or around your HVAC unit. When this happens, the fan won’t be able to operate efficiently. The key is to clear away debris regularly to prevent potential airflow problems.

Dirty Compressor

You should also keep an eye on the compressor. When it gets covered with dirt or leaves, it won’t be able to run as intended. Just be sure to shut off power to the unit before beginning work around the unit.

It’s also important to be familiar with how to clean the AC coils.

Check the Refrigerant Levels

Believe it or not, air conditioning coolant doesn’t go bad or expire, but it can leak out. Slow leaks can cause a problem over time, and this will result in your home not staying cool. When this occurs, your best bet is to have the unit serviced by a heating/cooling specialist.

Check for Ice Buildup

During the winter, dirty air filters or coils can cause poor airflow. When this happens, you might notice ice buildup on the unit. It’s important to clear away the ice and perform whatever maintenance is necessary to correct the issue.

Make Sure the Unit Has Power

Lastly, make sure the cooling unit doesn’t have a power problem. Check your breaker box for a thrown switch. After all, your house won’t be able to stay cool if your air conditioning unit doesn’t have the power to operate.
