It is very important to take care of our home heating and cooling systems. Air conditioners need on-time maintenance. Here are some tips to help increase the efficiency of your air conditioning unit and make your home cooler for less cost. 1. Clean debris from the unit’s housing and ensure that there is sufficient clearance around it. 2. Check air filters to ensure they are clean as dirty filters slow air circulation. 3. Ensure that ventilation fins are open properly. 4. Increase temperature settings when you are not in the home or at night while sleeping so that cooling is not wasted. 5.
