REPAIR OR REPLACE

Repair or Replace Your Dover Furnace or AC?

It depends on the system’s age and the failure. A capacitor, ignitor or flame sensor is usually worth repairing. A failed compressor or heat exchanger on an older system may not be. When repair no longer makes sense, Air Comfort gives free install estimates so you can compare both options. Read furnace repair or replacement, or see furnace installation and AC replacement.

  • New Trane heat pump installed outside a home in Dover, PA

    A RECENT DOVER JOB

    A Dover homeowner had an older system that ran on R-22, a refrigerant that has been phased out, and wanted something more efficient. Air Comfort replaced it with a new Trane heat pump outside and a matching Trane air handler in the basement, both running on a newer refrigerant. The new setup heats and cools from the same system.

    TIP FOR OLDER R-22 SYSTEMS

    If a system still runs on R-22, repairs keep getting more expensive because that refrigerant is no longer made. Planning an upgrade before it fails gives time to compare options instead of rushing a replacement.
