Repairing a Heat Pump in Gilbert

A heat pump in Gilbert cools through the long summer and heats on winter mornings, so it runs most of the year. Heat pump repair in Gilbert starts by testing both modes, because a reversing valve or defrost fault can stay hidden until the system tries to change over.

Signs to Watch For

  • Warm air in cooling mode or cool air in heating mode.
  • The outdoor fan does not spin while the unit hums.
  • Ice on the outdoor coil that does not clear on a cold morning.
  • Higher bills and longer run times than last year.
  • The breaker trips when the system starts.

What We Usually Find

Capacitors and contactors are the most common failures and quick to fix. A refrigerant leak shows up as weak output in both seasons, and we find and repair it rather than topping it off. A stuck reversing valve keeps the system in one mode. On cold mornings, a failed defrost control or backup heat strip can leave the house cool even when the compressor is fine.

Systems Original to the House

Many Gilbert heat pumps were installed when the house was built and are now 15 to 25 years old. Electrical parts on those are sensible repairs. A failed compressor or leaking coil on an older unit, especially an R-22 system, is where replacement usually makes more sense. R-410A heat pumps can still be serviced and charged; new equipment uses A2L refrigerants such as R-454B.

Before You Call

Check that the thermostat is in the right mode, the outdoor disconnect and breaker are on, and the filter is not clogged. If the outdoor unit is buzzing but not running, switch the system off at the thermostat. Running it in that condition can damage the compressor.

Common Questions

Why does the outdoor unit steam in winter?

That is the defrost cycle. Steam for a few minutes is normal; ice that stays is not.

Do you give the price before working?

Yes. You get the diagnosis and the price in writing before any part is replaced.
