Common Rheem Heat Pump Problems We Fix

No hot water / lukewarm water – sensor or thermostat faults, compressor not engaging, restricted airflow, low refrigerant, or timer/supply issues.
Error/fault codes – we read codes, test sensors (resistance checks), inspect wiring & PCB, and replace failed parts per Rheem guidance.
PTR valve constantly dripping – some discharge is normal; steady flow points to high pressure/temperature or a worn valve — we test/replace and verify pressures.
Runs constantly / short cycles – dirty/iced coil, blocked airflow, low ambient operation, control faults.
Noise & vibration – fan bearing wear, debris on evaporator, loose mounts, compressor issues.
Legacy MPi/HDi quirks – older MPi-325 / HDi-310 units may show controller or compressor wear; we diagnose and advise best-value repair vs. upgrade paths.

Rheem Heat Pump FAQs

Do you repair the Rheem AmbiPower 280e?

Yes — we regularly service AmbiPower 280e (R290, 280 L) including sensors, controller, fan/compressor, booster, and valves.

What’s special about the AmbiPower design?

It uses wrap-around microchannel heating for efficient, even heat transfer, and an enamel-lined tank for durability.

Why am I only getting warm water?

Likely causes include sensor/thermostat faults, restricted airflow, low ambient conditions pushing the unit into backup element use, or timer/supply settings. We test each component to restore performance.
