Heating & Cooling

Real diagnostics, every brand

Heat pumps are more complex than a basic furnace, and not every shop trains its techs on the variable-speed inverter side. We do. Common faults: low refrigerant, a frozen outdoor coil from a stuck defrost cycle, a failed reversing valve, or an inverter board throwing brand-specific codes.

We pull fault codes, verify refrigerant pressures by mode, test the defrost sequence, and check the electrical — real diagnostics, not guess-and-replace. After the fix, we run the system through both heat and cool to confirm it’s right before we leave.

Twice-yearly maintenance keeps a heat pump efficient and the warranty valid, and it’s doubly important on the Cape where salt air loads the outdoor coil. Ask about bundling it into a maintenance plan.

Heat Pump Repair & Maintenance — questions, answered.

  • A thin frost layer in heating mode is normal — a defrost cycle melts it every 30–90 minutes. If the unit is fully encased in ice, the defrost cycle isn’t running and it needs service.
