Describe the Failure Mode
Tell us whether the problem occurs in heating mode, cooling mode, or both. This helps us prepare for the right diagnostic approach.
Full System Diagnostic
We test the system through both modes, measure refrigerant pressures under load, check the reversing valve, and inspect the defrost system — heat pump-specific diagnostics that a standard AC diagnostic may miss.
Repair Estimate
We explain the cause, the parts needed, and the cost. For a failed reversing valve, we'll discuss whether it makes sense to repair versus evaluate replacement.
Repair and Both-Mode Verification
Repair completed and system tested in heating and cooling mode to verify the fix addressed the root cause.
