Heat pump not heating well? Learn common causes, from thermostat and power issues to dirty coils, duct leaks and blower problems, and when to call for repair.

If your home's heat pump is not providing enough heat, or is not producing any heat at all, it is important to have it checked. Because there are several possible reasons a heat pump can stop working properly, a professional diagnosis is the surest way to find the cause.
Knowing a little about the common reasons for a heat pump malfunction will also help you understand the repairs your technician discusses with you.
If your heat pump never seems to turn on, there is a good chance the heat pump itself is fine. The problem often has more to do with the thermostat or the power supply. Check the thermostat batteries and settings, and check the breaker or fuse that controls the unit. If the thermostat is the issue, your technician can also help you choose a more efficient smart thermostat.
If the air coming from your vents seems cooler than it should, a technician will check several components.
For example, dirty coils or a faulty blower could be at fault, so you may need a repair rather than a new heat pump. A leak in your ductwork can also let unheated air mix with the warm air before it reaches your rooms, in which case ductwork and airflow correction may be the answer.
If there is a problem with your blower motor or fan, you will have poor air circulation in your home. A failing motor can overheat or seize. If the system shuts down once, turn it off and give it time to rest. If it happens repeatedly, have a professional repair the problem.
On some older systems, a worn or broken fan belt causes similar airflow problems and affects how well your heat pump heats. Replacing the belt restores proper circulation.
