Heat Pump Problems in Tempe

Tempe homes run their cooling hard for most of the year, and a heat pump also covers the winter mornings. Heat pump repair in Tempe means testing both heating and cooling, because some faults only appear when the system switches modes.

Symptoms and What They Usually Mean

Symptom Likely cause
Wrong temperature air for the mode Reversing valve or its solenoid
Outdoor unit hums, fan does not turn Capacitor or fan motor
Weak output in both seasons Refrigerant leak or dirty coil
Ice that will not clear Defrost control or sensor
House stays cold on frosty mornings Backup heat strips not working

Rental Properties

For rentals, Tempe’s rental housing code sets cooling standards for habitable rooms, so a failed heat pump in summer is urgent. We can coordinate access with tenants and give the owner the diagnosis and price before work begins.

Older Systems

Some Tempe heat pumps still run R-22, which has not been produced since January 1, 2020, so a major leak on one is worth comparing with a replacement. R-410A systems can still be serviced and charged; new equipment uses A2L refrigerants such as R-454B.

How the Visit Goes

We test the system in both heating and cooling, measure electrical parts, check the refrigerant charge and look at airflow. You get the diagnosis and the price in writing before any part is replaced. Common parts are on the truck, so most repairs finish on the first visit.

Before You Call

Check the thermostat mode, the breaker and the outdoor disconnect, and change a dirty filter. If the outdoor unit hums without starting, turn the system off at the thermostat until we arrive.

Common Questions

Is steam from the outdoor unit normal in winter?

Yes, during defrost. Ice that stays on the coil is not.

Do you repair heat pumps on flat roofs?

Yes, including packaged heat pumps on rooftops, common on older Tempe homes.
