Common Heat Pump Problems We Fix
Heat pumps fail differently than cooling-only systems. These are the failures we diagnose and repair most often in the Birmingham area.
Not Cooling in Summer
Heat pump stuck in heating mode, low refrigerant charge, or reversing valve failure prevents cooling operation. The most urgent summer failure.
Not Heating in Winter
Reversing valve stuck in cooling position, defrost control failure, or refrigerant issues prevent heating mode operation.
Reversing Valve Failure
The reversing valve switches the heat pump between heating and cooling cycles. When it fails or sticks, the system cannot change modes and is locked in one direction.
Defrost Cycle Problems
Heat pumps must defrost the outdoor coil in cold weather. Defrost control board or sensor failures cause the coil to ice over and restrict airflow, eventually shutting the system down.
Auxiliary Heat Not Working
Dual-fuel or electric backup heat strips failing during cold snaps leave the home without adequate heat when outdoor temperatures drop below the heat pump's efficient operating range.
Compressor Failure
Heat pump compressors work year-round in both heating and cooling modes, accumulating more run hours than cooling-only systems. Higher duty cycles mean earlier compressor failures in some heat pump installations.
Heat Pumps in Alabama's Climate
Alabama's climate creates a particular set of conditions for heat pump operation. The long, hot cooling season means heat pumps in Birmingham accumulate more cooling-mode run hours than in most other states, which accelerates wear on compressors and reversing valves. Alabama winters are typically mild enough that heat pumps operate efficiently through most cold weather without backup heat, but occasional cold snaps into the teens and twenties test defrost controls and backup heat systems that may not have been exercised in years.
Dual-fuel heat pump systems, which pair an electric heat pump with a gas furnace backup, are increasingly common in newer Birmingham-area homes. These systems offer the efficiency advantages of heat pump operation in moderate weather with the reliable backup heat capacity of a gas furnace during cold snaps. Dual-fuel system failures require technicians who can diagnose both the heat pump circuit and the gas furnace backup — a capability our team maintains.
Heat Pump FAQ
How is a heat pump different from a standard AC system?
A heat pump moves heat in both directions — removing heat from inside your home in summer (cooling) and extracting heat from outdoor air to warm your home in winter (heating). A standard AC system only cools. Heat pumps use a reversing valve to switch between modes. This makes heat pumps more versatile but adds components — the reversing valve and defrost system — that do not exist in cooling-only systems.
My heat pump is blowing cool air in heating mode. What's wrong?
Heat pumps produce air that feels less warm than a gas furnace — typically around 90 to 95 degrees at the supply register compared to 120 to 140 degrees from a furnace. This is normal. However, if the air is noticeably cool or cold in heating mode, the reversing valve may be stuck in cooling position, refrigerant charge may be low, or the outdoor coil may be iced over and unable to extract heat from the air.
Should I repair or replace my heat pump?
The same repair-versus-replace guidance applies to heat pumps as to cooling-only systems. Component failures in systems under 12 years old almost always make sense to repair. Compressor failure in older systems, especially combined with refrigerant issues, warrants a replacement discussion. Our technicians provide honest guidance based on your system's specific age, condition, and failure type.
Can you work on mini-split heat pumps?
Yes. We service ductless mini-split heat pumps from all major manufacturers including Mitsubishi, Daikin, Fujitsu, LG, Samsung, and others. Mini-splits have different diagnostic procedures and some proprietary components, but our technicians are trained and equipped for them.
Heat Pump Not Working?
Whether it's a cooling failure in July or a heating failure in January, our technicians understand heat pump systems and have parts on hand for the most common repairs.
