Heat Pump Repair in Tempe, AZ
A heat pump does the work of both an air conditioner and a furnace, moving heat in or out depending on the season. When it fails, the problem could be in the refrigerant circuit, the reversing valve that switches modes, the defrost controls, or the electrical components. Heat pump diagnosis takes more steps than a standard AC call because there are more operating modes to check. Misdiagnosing a heat pump is common — we don't skip steps.

When to Call
When You Need Heat Pump Repair
- Your system blows cold air in heating mode and the auxiliary heat strips are running constantly.
- The unit won't switch from cooling to heating when temperatures drop in late fall.
- You hear a loud bang or gurgle from the outdoor unit when it tries to run in heating mode.
- Your heat pump ices over on the outdoor coil and never seems to go through a defrost cycle.
How It Works
Our Process for Heat Pump Repair
- 1
Identify the Operating Mode Failure
We test the system in both heating and cooling modes to understand exactly where the failure occurs and what conditions trigger it.
- 2
Check the Reversing Valve and Controls
The reversing valve is the component unique to heat pumps. We test it electrically and physically to determine if it's stuck or failed.
- 3
Inspect Refrigerant Circuit and Defrost
We check pressures, check defrost board timing and sensors, and look for refrigerant issues that affect heating performance specifically.
- 4
Repair and Confirm Both Modes Work
After repair, we test the system in both heating and cooling mode before leaving. A heat pump that only works in one mode isn't fixed.
Tempe Context
Why this matters in Tempe
Tempe's mild winters mean heat pumps here rarely get the cold-weather workout that causes defrost and reversing valve issues in northern climates. When those problems do show up, it often catches homeowners off guard because heating season is short.
Straight Talk
About pricing & scope
Heat pump repairs vary in cost based on what failed — a defrost sensor is a different job than a reversing valve replacement. We tell you what we found and what the repair involves before any work starts.
