Ice buildup, short-cycling, “cooling only,” expensive electric strip heat runtime, or error codes on communicating systems.
Challenges we see with heat pump repair
Defrost and auxiliary heat confusion
Homeowners often think the system is broken when strip heat is doing its job — we separate normal from failed.
What we do on site
Mode-aware diagnosis
Verify reversing valve behavior, outdoor fan, sensors, and indoor airflow for the mode that fails.
Clear repair plan
Parts and labor scoped before work when the fault is identified.
Failure modes to avoid
Treating a heat pump like a one-way AC
Heating-mode faults need heating-mode tests.
Proof & methodology
- · Growing heat-pump adoption in NoVA — local housing and utility context.
- · Honest repair vs. replace conversations.
