Summer is in full swing here on the seacoast! Here are some ways homeowners can maintain their air conditioning systems:

1. Clean the coils. Over time, the evaporator and condenser coils can collect dirt and dust, which can reduce airflow and make the coils inefficient. Cleaning the coils can help keep the system running efficiently.

2. Clean the condensate drain. Regular cleaning of the condensate drain can prevent clogs from forming due to debris like dirt, dust, algae, mold, and mildew.

3. Change the air filter. A clean air filter can improve indoor air quality, keep dust out of fans, motors, and coils, and filter more dust from the air. The U.S. Department of Energy recommends routine filter maintenance to improve the capacity and output of your air conditioning system.

4. Schedule annual tune-ups. An HVAC professional can service your air conditioner twice a year to keep the drain line clear and perform other routine maintenance.
