Heat Pump Repair Service in Richardson, TX
Heat pump repair addresses the specific failure modes that make a heat pump different from a standard AC — reversing valve failures, defrost cycle problems, and refrigerant issues that show up differently in heating mode than in cooling mode. A heat pump that blows cool air in January isn't necessarily broken the same way an AC is broken in August, and misdiagnosing it wastes time and money. We've worked on heat pumps long enough to know that the reversing valve is often the first suspect but not always the actual problem. Accurate diagnosis here saves you from replacing a part that wasn't actually bad.

When to Call
When You Need Heat Pump Repair Service
- Heat pump is blowing lukewarm air in February and auxiliary heat is running constantly
- System switched to cooling mode on a cold morning and won't reverse back
- Outdoor unit is iced over in winter and defrost cycle never kicks in
- Heat pump runs continuously but can't keep up with a 28-degree night in Richardson
How It Works
Our Process for Heat Pump Repair Service
- 1
Mode-Specific Diagnosis
We test the system in both heating and cooling mode before drawing conclusions, because some faults only appear during one operating mode.
- 2
Reversing Valve and Refrigerant Check
We check reversing valve operation and refrigerant charge together, since low charge and a stuck valve produce similar symptoms but require different fixes.
- 3
Defrost and Controls Test
Defrost board, outdoor sensor, and defrost timer are tested sequentially so we know whether the icing problem is a controls failure or a refrigerant issue.
- 4
Repair and Full-Cycle Test
After repair, we run the unit through a complete heating and cooling cycle to confirm the reversing valve transitions cleanly and temperatures respond correctly.
Richardson Context
Why this matters in Richardson
North Texas winters are short but they include enough near-freezing nights that heat pump defrost cycles matter here. A system that never gets properly tested in heating mode during our mild fall weather can fail unexpectedly when a hard freeze arrives.
Straight Talk
About pricing & scope
Reversing valve replacement is more labor-intensive than most single-component repairs, which affects overall job cost. Refrigerant leaks require locating the source, not just recharging, or the problem will return within one season.
