Maintaining Heating and Cooling System

It’s important to have your home’s heating and cooling systems running efficiently in order to keep you comfortable.

  • Use heating and cooling equipment approved by the E-P-A, bearing the Energy Star logo so that it stretches your energy dollar without sacrificing comfort.
  • For example, a properly sized and installed Energy Star air conditioner uses 20-percent less electricity than a standard air conditioner.
  • Clean your filters monthly. Dirty filters make equipment work harder and cause more wear and tear on your system, shortening the life of the unit.
  • Finally, have heating and cooling equipment installed and serviced by NATE-certified technicians.
