If your heat pump isn’t keeping your home warm like it used to, you’re not alone. Many homeowners experience heating issues with their systems, especially during temperature swings or after years of regular use. A properly functioning heat pump should deliver consistent comfort, even on chilly days, so when it doesn’t, it’s a sign that something’s not right. The good news? Most issues can be diagnosed and resolved quickly.
1. The Heat Pump Is in Cooling Mode
It may sound obvious, but it’s worth checking: Is your heat pump accidentally set to “cool”? Heat pumps are versatile units that handle both heating and cooling. During seasonal transitions, it’s easy to overlook the settings on your thermostat. Make sure the system is set to “heat” and that the temperature is set higher than the current room temperature.
2. Clogged Air Filters or Blocked Airflow
Restricted airflow can significantly reduce your system’s efficiency. Dirty air filters, blocked vents, or obstructed outdoor units make it harder for your heat pump to circulate warm air. Try replacing the filters and ensuring that nothing is blocking the indoor or outdoor units. Regular maintenance can go a long way toward preventing this common problem.
3. Refrigerant Issues
Heat pumps rely on refrigerant to transfer heat from the outside air into your home. If there’s a leak or the refrigerant is low, the system won’t be able to generate enough warmth. You might notice that the system runs constantly without achieving the desired temperature. In this case, you’ll need professional help. If you’re searching for reliable heat pump repair in Katy, TX, with HVAC service professionals you can trust, it’s time to call AC Comfort.
4. Faulty Thermostat or Electrical Issues
Sometimes, the issue isn’t with the heat pump at all but with the thermostat or the electrical components controlling it. A malfunctioning thermostat may fail to send the right signals to the unit. Similarly, a worn-out capacitor, contactor, or other electrical part could disrupt the system’s operation. These issues require diagnosis and repair by an HVAC service professional.
5. Icy Outdoor Unit
During colder spells, it’s normal for frost to form on the outdoor coils. But if the unit becomes completely encased in ice, something is wrong. Your heat pump should automatically enter a defrost cycle to prevent this. If it doesn’t, the defrost control board, sensor, or reversing valve might be to blame.
When to Call a Professional
Some problems—like a dirty filter or an incorrect thermostat setting—are easy fixes. Others, such as refrigerant leaks or electrical issues, require licensed HVAC service professionals. Ignoring these can lead to bigger problems and costlier repairs down the road.
