A broken heat pump produces a bedroom-free zone of pain, bringing high temperatures in the summer and low temperatures in the winter, as well as ongoing maintenance expense worry. At Southport Heating and Air, we understand how important it is for heat pumps to run well. Southport Heating and Air’s article below provides homeowners with practical answers to the 10 most common heat pump problems, as well as signals that indicate when professional help is required. Let’s dive in!
Heat Pump Running Constantly
A heat pump that never turns off is more than simply annoying; it’s a sign of a problem. A thermostat problem is frequently its main cause. If the thermostat isn’t measuring temperatures correctly, your system may overwork itself to reach an unachievable setting. Dirty air filters or blocked AC coils may cause the unit to work harder. More significant concerns require professional evaluation, such as refrigerant leakage or an inappropriately sized system (too small for your home). Many of these issues can be avoided with regular maintenance, such as filter replacement and coil cleaning.
Heat Pump Not Running
If your heat pump doesn’t start, try the basics: Is the thermostat set correctly? Are the registers open? The problem could be caused by either electrical components triggered by the circuit breaker or windows that have blown fuses. The system may face problems as a result of badly functioning heat pump components such as the starter capacitor and reversing valve. When an electrical problem arises, it is critical to contact a certified specialist rather than attempting your own unsafe repairs.
Outdoor Unit Is Frozen
The creation of ice on the outdoor unit during defrost cycles is normal in cold weather, but persistent ice indicates a problem. Three problems can interfere with appropriate defrost cycles: obstructed airflow from plants, faulty exterior fans, and leaking refrigerant. Systems with filthy air filters or condenser coils increase their burden due to excessive condensation, which causes freezing temperatures. Thaw your system fully, then contact maintenance if you notice any ice accumulation.
Indoor Air Handler Not Working
Poor airflow in your rooms may indicate that your air handler needs to be checked. A tripped circuit breaker, combined with unsecured wiring, might cause power loss to the blower motor. In other cases, the fault can be with the motor’s composition or outlet. Quick repairs for this important air distribution part are required because it maintains proper air movement throughout the building. Ignoring immediate maintenance causes temperature fluctuations and system wear.

Heat Pump Not Heating
If your heat pump is not producing heat, it is important to find out the problem. Common causes include thermostat issues, unclean air filters, and refrigerant leakage. Furthermore, a clogged outdoor unit or leaking ducts could affect the system’s heating efficiency. To solve these problems, clean or replace the filters, repair any duct leaks, and inspect the outdoor unit for obstructions. Taking these simple measures usually restores proper heating function.
Heat Pump Not Cooling
When your heat pump fails to cool the space, it is frequently due to the same reasons that affect heating. Dirty air filters, refrigerant leaks, or a defective reversing valve can all reduce cooling effectiveness. A clogged outdoor unit or unclean AC coils can also reduce airflow and cooling capability. To remedy these difficulties, make sure the outdoor unit is debris-free and the coils are clean. If the problem persists, contacting a specialist for refrigerant or valve repairs is critical.
Heat Pump Not Switching Modes
If your system does not switch between heating and cooling, the reversing valve is either jammed or malfunctioning. This valve directs the flow of refrigerant, and replacing it requires specific tools. Allow specialists to perform this repair to avoid causing damage to other components.
Heat Pump Short Cycling
Short cycling occurs when heat pump systems have continual short-duration operational cycles. Rapid starts and stops reduce system efficiency and accelerate component depreciation. The system overheats when the heat pump is too small for the room, has leaks, or maintains high temperatures. Poor system performance comes as a result of a poor thermostat position, which causes the system to detect temperatures incorrectly. Quick answers to these system issues will improve both system performance and lifespan efficiency.
Heat Pump Leaking Liquid
Your heat pump leaks because of two main reasons: refrigerant leaks or a clogged drain line. A refrigerant leak reduces performance efficiency and causes pollution damage to the environment. Water accumulates as drain pipes become clogged, resulting in an overflow. Inspection and maintenance operations assist prevent leaks from forming. A professional should tackle refrigerant issues since they provide safe and efficient troubleshooting.
Weird Smells From the Heat Pump
The odors of your heat pump indicate mold growth and may also indicate the presence of animals within the system, as well as potential electrical issues. Mold grows naturally in damp environments, which build in clogged drain lines and dirty filters. A bad odor during nesting suggests the presence of animals, whereas electrical difficulties cause burning or chemical-like odors. Cleaning filters and keeping the system fully dry can assist fix problems. If you find electrical difficulties with your heat pump, turn it off immediately and contact a trained professional for assistance.
Preventative Maintenance: Your Best Defense
Many heat pump problems result from neglect. Simple behaviors such as replacing air filters on a monthly basis, keeping outdoor units clean, and scheduling annual tune-ups can help your system last longer. During routine maintenance visits, personnel inspect refrigerant levels, test electrical connections, clean coils, and calibrate thermostats.
