Heat Pump Repair in Foley
Most homes on the coast heat and cool with a heat pump, so one failure can take out both. Contractors we connect you with diagnose reversing valves, defrost boards and sensors, low refrigerant and failed heat strips, then quote the repair before starting. Cold snaps are short here, but a dead heat pump on a 30-degree morning still needs a same-day answer.
Call (251) 270-2500. The phone is answered 24/7, and same-day service from a local HVAC contractor is available in most of South Baldwin.
How a Heat Pump Heats Your Home
In winter, a heat pump runs its refrigeration cycle in reverse. The reversing valve switches the flow so the outdoor coil gathers heat and the indoor coil releases it. A TXV or other metering device controls refrigerant flow, and a suction line accumulator protects the compressor from liquid refrigerant.
On cold, damp mornings, frost forms on the outdoor coil. A defrost control board and defrost sensor watch for it and switch the system briefly back to cooling to melt it off. That is the steam and whoosh you sometimes see. During defrost, auxiliary heat strips in the air handler keep the air from the vents warm.
When the heat pump cannot keep up at all, the thermostat’s emergency heat setting runs the heat strips alone. It works, but it costs much more to run.
Common Heat Pump Problems
Not heating, or blowing cool air
A stuck reversing valve, low refrigerant from a leak or a failed heat strip sequencer are common causes. Thermostat settings are worth checking first. Read heat pump not heating for safe checks.
Iced over and staying that way
Light frost that clears every so often is normal. A coil encased in ice points to a failed defrost sensor or board, low charge or a fan problem. See the heat pump defrost cycle explained.
Stuck on AUX or EM heat
If auxiliary heat runs constantly in mild weather, the heat pump may not be pulling its weight, and your bill will show it. Some systems use an outdoor ambient thermostat to lock out the heat pump or heat strips at certain temperatures, and a wrong setting can cause trouble. Learn what emergency heat means.
Not cooling in summer
A reversing valve stuck in heating mode, or any of the usual AC faults, can stop a heat pump from cooling. The same call covers it.
Heat Pump Service in Gulf Shores and Orange Beach
Beach-town heat pumps face salt air on the outdoor coil all year, which adds corrosion to normal wear. Condo units on balconies and rooftops are harder to reach, and raised beach houses have outdoor units on elevated stands. The contractors we connect you with work these setups regularly and coordinate access with building managers.
Heat Strip and Emergency Heat Repair
Heat strips fail in a few predictable ways: a burned-out element, a failed sequencer or relay, or a tripped limit switch. The contractor tests each one. If you are on a dual-fuel system, the gas furnace side gets checked too.
What the thermostat and the outdoor unit are telling you:
| What you see | What it means | When to call |
|---|---|---|
| HEAT | The heat pump alone is heating the house | Air from the vents stays cool, or it runs nonstop and cannot keep up |
| AUX heat | Heat strips are helping the heat pump | It shows almost all the time in mild weather |
| EM heat | Heat strips only; the heat pump is locked out | You need it at all, since the heat pump is not doing its job |
| Frost and steam on the outdoor unit | A normal defrost cycle | Ice stays on the coil and does not clear |
Efficiency and Replacement
If your heat pump is old, uses R-22 or needs a compressor, ask for a replacement quote. New heat pumps carry HSPF2 heating efficiency ratings alongside SEER2. Our guide to heat pump vs furnace on the Gulf Coast compares options for mild coastal winters.
