Residential Heat Pump Repair
Roxly diagnoses and repairs heat pump problems for homes throughout the Charlotte metro area, with findings and an estimate reviewed with you before any work begins.
Common heat pump problems
- The heat pump runs but the house doesn't warm up in winter
- Ice building up on the outdoor unit and not clearing
- The system stuck in defrost mode
- Cool air blowing when the thermostat calls for heat
- The outdoor unit not running at all
- Auxiliary/emergency heat running constantly
- Unusual noise from the outdoor unit
- Higher electric bills with no change in usage
What's usually behind it
Heat pumps depend on a reversing valve, defrost control board, outdoor fan motor, and refrigerant charge — any one of which can leave the system stuck in the wrong mode or unable to keep up.
Repair, not replace
A stuck reversing valve or a defrost-board fault is a targeted repair, not a reason to replace a heat pump that's otherwise sound. Service availability may vary by location, equipment type, brand, technician availability, licensing requirements, and the scope of the requested work. Contact Roxly Appliance & Refrigeration Repair to confirm service availability for your address and equipment.
Safe checks before you call
- A light, even coat of frost on the outdoor coil in winter is normal — a heavy buildup that doesn't clear during a defrost cycle is not.
- Confirm the outdoor unit has clearance and isn't blocked by snow, mulch, or debris.
- Check the thermostat is set to Heat (not Emergency Heat, which bypasses the heat pump).
Beyond these basics, leave refrigerant, gas, and internal electrical components to a technician.
Frequently asked questions
Why does my heat pump blow cool air in winter?
Heat pump air is naturally cooler than a furnace's, but if the house isn't warming up, check for a stuck reversing valve, low refrigerant, or the system stuck in defrost.
Is heavy ice on my heat pump normal?
A light frost is normal in cold, humid weather and clears during scheduled defrost cycles. Heavy ice that doesn't clear points to a defrost-control or reversing-valve fault.
Do you install new heat pumps?
No — Roxly repairs and maintains existing residential heat pump systems, not new installation or full replacement.
Why is emergency heat staying on?
Emergency heat is a backup that shouldn't run continuously. If it is, the heat pump itself likely has a fault preventing normal operation.
