Here in Durham, NC, using heat pumps makes sense. The system is an ideal investment that provides you with both a heater and an air conditioner.
Heat pumps can keep you cool on the hottest summer days and cozy in the coldest winter nights. They are efficient systems that use a reversible refrigerant cycle to provide you with energy-efficient cooling and heating.
If you notice that your heat pump is not heating while you are in the middle of winter, it’s a sign that there could be a significant problem in your hands. We will discuss the reasons why your heat pump is not heating, so you can understand the importance of calling in the professionals for heat pump repair before things get worse.
Why Your Heat Pump Isn’t Heating
Here are the reasons why your heat pump is not providing you with the heat you need for comfortable indoor temperatures in winter.
Clogged Air Filter
The unit relies on pulling in air from the house and redistributing it after regulating the temperature using the refrigerant cycle and heat exchange process. As you keep running the heat pump, its air filter starts to build up dirt and dust. If you do not keep cleaning or replacing the air filter regularly, it can begin to clog up. Without proper airflow, the coil responsible for heating and cooling the air can freeze.
Sometimes the problem is not with your heat pump itself. The thermostat works as the central control unit for your heat pump, and it is responsible for regulating the temperature. If your thermostat is malfunctioning, it cannot properly control the temperature and leads to lower heat.
The heat pump relies on refrigerant in the system for heat transfer to warm up the air it circulates around your home. One of the reasons your heat pump is not heating is due to leaking refrigerant. It could be a minor leak or a major rupture that lets all the refrigerant out, causing your heat pump to struggle to warm your home properly.
Reversing Valve Is Stuck
The reversing valve in your heat pump allows it to function as both a heater and an air conditioner. The refrigerant lets you transfer the heat out during the summers. When it is cold, the reversing valve allows you to transfer heat in. A reversing valve stuck in the heating position can also cause your heat pump to malfunction.
There are chances that there is a leak in your ductwork that is causing the warm air to leak out. The breach in your ductwork can allow the cold air to enter the system and into circulation. While your heat pump might be working properly, leaking ductwork can cause it to lose heat before the warm air goes into circulation.
Always Call in the Professionals
If your heat pump starts to blow cold air or you notice that it is not as efficient as it used to be, you need to examine the unit for any of these problems. You can replace the air filter easily to correct a clogged airflow. However, other issues require professional expertise, training, and experience to resolve. That’s where we come in.
