Winter Signs Your Heat Pump Needs Repair
- Ice covers the outdoor coil and is still there hours later
- The thermostat shows “aux heat” on most of the day, even on mild afternoons
- The indoor fan runs, but the outdoor fan and compressor don’t
- The system won’t switch from cooling to heating, or gets stuck in one mode
- The breaker trips when backup heat comes on
- Your winter electric bill jumps with no change in the weather or your settings
A working heat pump can use up to 75% less electricity for heating than electric resistance heat. Backup heat strips are electric resistance heat, so when they carry the load your bill climbs fast.

Every heat pump frosts up in cold, humid weather and clears it with a defrost cycle. Here’s how to tell the difference.
Normal defrost
- A thin, even layer of frost on the outdoor coil
- The outdoor fan stops for a few minutes
- A whoosh as the system shifts into defrost and back
- Steam rising off the unit as the frost melts
- The frost is gone when the fan starts again
Ice that needs a technician
- A thick block of ice that hides the coil fins
- Ice on the top of the unit or around the fan
- Ice that stays through several cycles
- Ice on the refrigerant lines leading into the house
Thick ice that won’t melt often points to a failed defrost control board, a bad outdoor fan motor or a refrigerant leak. It can also come from restricted airflow, which you can check yourself.
What to Do If Your Heat Pump Freezes Up
Turn the system off
Set the thermostat to Off so the heat pump stops running on a frozen coil. If you need heat while you wait, switch to emergency heat.
Check the filter
A clogged filter cuts airflow and can lead to icing. Replace it if it’s dirty. Filters should be changed every 1 to 3 months.
Open vents and clear the unit
Open closed registers, then brush snow, leaves and debris off the outdoor unit so air can flow.
Call us
If ice returns after the system restarts, call 540-300-6932. We’re available 24/7.
Never hit or pry ice off the coil with a tool. The aluminum fins and refrigerant tubing are thin and easy to puncture, which turns an icing problem into a refrigerant leak.
Common Heat Pump Repairs We Make in Fredericksburg
These parts are unique to heat pumps or work harder in one than in a standard air conditioner.
| Part | What you notice | What it does |
|---|---|---|
| Reversing valve | Stuck in cooling or heating, won’t switch modes | Changes the refrigerant’s direction so one system can heat and cool |
| Defrost control board | Ice builds up and never clears | Decides when to run a defrost cycle and ends it |
| Outdoor fan motor | Fan won’t spin, or spins slowly, while the compressor hums | Pulls outdoor air across the coil so the system can collect heat |
| Backup heat strips and sequencer | No backup heat on the coldest nights, strips that never shut off, or a tripped breaker | Adds electric heat in stages when the heat pump needs help |
| Refrigerant leak | Weak heat, heavy icing, a hissing sound | Refrigerant carries heat between the outdoor and indoor coils |
| Thermostat, sensors and wiring | Short-cycling, wrong mode, aux heat running when it shouldn’t | Tell the system what mode to run and when to call for backup heat |
Heat pump fine in winter but not cooling in summer? That’s an AC repair call. If your backup heat is a gas or oil furnace and the furnace is the part failing, see furnace repair.
Repair or Replace Your Heat Pump?
A failed sensor or fan motor is usually a straightforward repair. If your heat pump is near the end of its life, needs a major part like a compressor, or leans on backup heat more each winter, a new system may cost less over time. We’ll price both honestly.

Heat Pump Repair FAQs
How much should aux heat run on a 23°F January night in Fredericksburg?
There’s no set number of hours, but it shouldn’t run all night. January’s average low here is 23°F, and cold-climate heat pumps are built to keep heating down to about 5°F. On a typical January night, aux heat should come on briefly during defrost or when you raise the thermostat, then shut off. If it stays on for hours, call us.
Is it OK to switch to emergency heat while I wait for a repair?
Yes. If the outdoor unit is iced over or not running, emergency heat keeps the house warm using only your backup heat. Expect a higher electric bill if your backup is electric strips, so use it as a short-term fix and get the heat pump repaired.
Can I melt or knock the ice off my heat pump myself?
Don’t knock or chip it, since you can puncture the coil. Turn the system off, clear the unit and check your filter. If thick ice comes back after it restarts, call us.
Should I cover my outdoor heat pump unit in winter?
No. A heat pump runs all winter and needs open airflow around the outdoor coil. A cover traps moisture and blocks air, which can lead to icing. Keep the unit clear of snow, leaves and shrubs instead.
Why does my heat pump go into defrost so often on damp winter mornings?
Frost forms fastest on the outdoor coil when it’s cold and humid, which describes a lot of Fredericksburg winter mornings. A thin layer that clears during each defrost cycle is normal, even if it happens several times a morning. If the ice keeps getting thicker between cycles, or the coil stays white all day, the defrost control, outdoor fan or refrigerant charge may need attention.
