Heat Pump Not Heating in San Angelo, TX
A heat pump that cools but will not heat often points to a reversing valve or defrost issue. The system runs, but the air never warms up.
Common Causes
Reversing Valve Failure
The reversing valve switches between heating and cooling. If it sticks, the heat pump may stay in cooling mode.
Low Refrigerant
A refrigerant leak reduces the heat pump's ability to pull heat indoors.
Defrost Cycle Issue
A stuck defrost cycle can leave the outdoor unit iced over and stop heating.
Auxiliary Heat Failure
If the backup heat is not working, the home stays cold when the heat pump alone cannot keep up.
When to Call for Service
Check the thermostat setting first. If the heat pump still does not heat, request service. See heat pump repair.
