Question 1

Why has my heat pump stopped heating completely?

Accepted Answer

Typical emergency causes are a stuck reversing valve (leaving the system in cooling mode), insufficient refrigerant charge, compressor failure, or an electrical fault. Our technician will pinpoint the root cause and walk you through repair options.

Question 2

My outdoor heat pump unit is completely frozen — is this an emergency?

Accepted Answer

A thin layer of frost during cold operation is expected. Solid ice encasing the entire coil is not — it usually points to a refrigerant leak, blocked airflow, or a defrost control failure and warrants a service call.

Question 3

Can you fix any brand of heat pump in an emergency?

Accepted Answer

Absolutely. Our trucks carry parts for every major heat pump manufacturer plus universal components that fit most systems. Occasionally a brand-specific part must be ordered, but that is uncommon for emergency repairs.

Question 4

Why does my heat pump switch to auxiliary heat so often?

Accepted Answer

Auxiliary heat kicks in when the heat pump can't keep up with demand — usually when outdoor temps drop below 30–35°F, which happens regularly in WNC winters. However, if aux heat is running at 40°F or above, something is wrong: dirty coils, low refrigerant, a bad outdoor fan motor, or an oversized thermostat differential can all cause premature aux engagement. Since aux heat uses expensive electric resistance strips, this can triple your power bill — get it diagnosed quickly.

Question 5

My heat pump stopped heating overnight — what should I check before calling for repair?

Accepted Answer

First, make sure your thermostat is set to 'Heat' (not 'Cool' or 'Emergency Heat'), check that the outdoor unit isn't buried in snow or ice, and verify the breaker hasn't tripped — heat pumps use two breakers, one for indoors and one for outdoors. If the outdoor fan isn't spinning but the indoor blower runs, you likely have a failed capacitor or contactor, which is a same-day repair for us.

Question 6

Why is my heat pump covered in ice?

Accepted Answer

A light coating of frost on the outdoor coil during heating season is completely normal — your system should defrost automatically every 30–90 minutes. If the entire unit is encased in thick ice, the defrost cycle has failed, typically due to a bad defrost control board, a stuck reversing valve, a faulty defrost sensor, or low refrigerant. Running a heat pump with heavy ice buildup can bend fan blades and damage the compressor, so shut it down and call us right away.

Question 7

Can I pour hot water on my frozen heat pump to defrost it?

Accepted Answer

We don't recommend it — the thermal shock can crack the coil fins, and any water that pools around the base will refreeze and make the problem worse. If your unit is iced over, switch the thermostat to 'Emergency Heat' to protect the compressor and call for service. In a pinch, you can run a garden hose with lukewarm (not hot) water, but the real fix is repairing whatever caused the defrost failure.

Question 8

My heat pump is making a grinding or screeching noise — what's wrong?

Accepted Answer

Grinding or screeching from the outdoor unit typically means a failing fan motor bearing or a fan blade hitting something — ice, debris, or a shifted shroud. From the indoor unit, it usually points to a blower motor bearing failure. Shut the system off immediately to prevent further damage; running a motor with seized bearings can burn out the winding and turn a $300 repair into a $900 one.

Question 9

What should I do if my heat pump stops working in the middle of winter?

Accepted Answer

First, switch your thermostat to 'Emergency Heat' — this activates your backup electric heat strips (or gas furnace in a dual fuel system) to keep your home warm while you wait for service. Check the outdoor breaker and look for ice buildup on the unit. Then call us — we offer same-day and emergency heat pump repair in the Asheville area because we know that going without heat in a WNC winter isn't an option.

Question 10
