Still HaveQuestions? Let Us Help

Why is my heat pump not heating in winter?

Several issues can cause this — a failed reversing valve, low refrigerant, a faulty defrost control, or a stuck auxiliary heat setting. Because a heat pump both heats and cools, diagnosing the exact cause takes an experienced technician. We test the full system and pinpoint the real problem.

Some frost is normal in winter, and your heat pump periodically runs a defrost cycle to clear it. But if the unit is fully iced over or stays that way, it usually signals a defrost control, sensor, or airflow problem that needs professional attention before it damages the system.

Heat pumps run longer than furnaces by design, especially in very cold weather — that's normal and efficient. But constant running paired with weak heating or high bills can indicate low refrigerant, a dirty coil, or a failing component. We can determine whether it's normal operation or a real issue.

It depends on the age of your system and the cost of the repair. Heat pumps typically last 10–15 years. If yours is newer, repair is usually the smart choice. For older systems with major repairs, we'll give you an honest comparison so you can decide what makes financial sense.

It depends on the specific issue — some fixes are minor, others involve major components. We provide upfront pricing after diagnosing your system, so you know exactly what the repair will cost before we begin, with no surprise charges.
