Benefits of Routine AC Maintenance

An air conditioner that fails to cool when the temperatures soar past 80 degrees is a nightmare. Regular AC maintenance can help reduce the risk for an AC unit failure by:

  • Inspecting the thermostat, filter, and refrigerant pressure
  • Running a noise-level check
  • Checking the condenser coils, air flow, pump, and evaporator drainage
  • Setting the humidifier to summer position

Scheduling this annual AC maintenance is essential to the unit running smoothing and efficiently. Get in touch with us today for an AC repair, installation, or maintenance appointment. We also offer amazing heating services too!
