Summer is finally here, which means you'll be using your AC on a daily basis. That's why it's so troubling when your cooling system begins blowing hot air. While you should always hire an air conditioner contractor to perform repairs, there are also maintenance steps you can take to remedy the problem. The first step is to determine why your air conditioner is having issues. 

3 Common Reasons Why AC Units Blow Warm Air

1. Clogged Condenser

AC units cool your home using refrigerant, which absorbs warm air. The refrigerant then flows outside to the condenser, where heat is released. Plant debris like leaves and twigs can make their way into the condenser, preventing it from releasing the hot air. 

Condensers can also be blocked by furniture or lawn care equipment. Removing debris as needed and keeping a two-foot clearance around the unit will help it function efficiently. 

2. Dirty Air Filter

Airflow can also get blocked within your home. This usually occurs when the air filter needs to be changed. Air filters pick up allergens and other contaminants to prevent them from being dispersed around the home. When they become too dirty, they will no longer cleanse the air. 

Depending on how clogged they are, they might also restrict airflow out of the unit. Change filters at least once every three months. If you have pets in the home or suffer from allergies, changing them every 20 to 45 days is recommended. 

3. Leaking Refrigerant

Refrigerant circulates through a closed system, which means insufficient levels indicate a leak. A cracked evaporator coil, which is where heat is absorbed in your home, will allow the refrigerant to leak out. 

Defects in hoses and connections can also release the liquid. In this case, an air conditioner contractor can determine where exactly the leak is coming from and replace any worn or damaged parts contributing to the issue.
