When it comes to comfort systems, heat pumps are one of the most effective and efficient sources out there. These units can produce both warm and cool air. However, what if your heat pump refuses to keep your house warm when it’s freezing outside? Before performing heat pump repair, you read this blog to know what might be causing the issue and how you can solve it.
A Clogged Air Filter
One of the most popular reasons behind heat pumps not warming or cooling the house is a clogged air filter. These filters are installed inside the unit and are designed to prevent toxicants and contaminants from entering the house. That said, the air filters are bound to get dirty and clogged after some time.
If you go through the user’s manual, you will come across the manufacturer recommending a certain time period after which the air filters either need to be cleaned or replaced. Another drawback of a clogged air filter is that it pushes the unit to work harder than usual.
It puts an extra burden on the unit and it may also cause some components to go faulty. Therefore, you must regularly check the air filters based on your usage and keep them clean.
The Heat Pump’s Type Or Size Does Not Suit Your House
You might have come across people buying new air conditioners only to complain that they are not effective enough to keep their rooms or the house cool. And in most cases, the problem comes out to be that the homeowner tends to buy air conditioners of the wrong size and type.
The size of a heat pump has to do a lot with its cooling efficiency and effectiveness. If you have a relatively large room/house and have installed a smaller size, it will struggle to keep the room/house cool.
It might be that you have selected the wrong size. If your house is bigger than the average properties out there, you will need a bigger heat pump as well. Therefore, it is better that you consult an expert to find out if you really need a heat pump or some other type to effectively warm your house.
The Reversing Valve Is Broken
This valve lets you switch the unit from cooling to heating and vice versa. It is basically a valve that controls the direction in which the refrigerant will move after leaving the compressor. So, if the valve goes stuck or faulty, it means the heat pump won’t be able to switch from one mode to another. That said, if you are not getting any heat from your heat pump, it means the valve might be broken or faulty. Consult a professional to replace the reversing valve.
Faulty Thermostat
Another possible reason your heat pump might not be warming your house is a faulty thermostat. Thermostats are electric devices that keep track of both the outside and inside temperature. If the thermostat on your heat pump goes faulty for some reason or is not correctly calibrated, do not be surprised if your heat pump is not warming up the house.
To make sure the thermostat is the actual issue, you will need to consult a professional who will check for any damages or faults. And if the thermostat has malfunctioned, you might need to replace it.
Blocked Outdoor Unit
The outdoor unit takes a regular beating during extreme weather conditions. Whether it is blazing hot or freezing outside, the outdoor unit has to bear it all. That said, in the winter season, the outdoor unit can get blocked due to snow. The unit won’t be able to pull any heat. Therefore, you need to make sure that the outdoor unit is free of snow and other external factors that might impede its performance.

In the end, there could be several reasons contributing to your heat pump not working as it is supposed to. However, you should keep the above-mentioned factors in mind to help troubleshoot the issue. Keep in mind that you most probably need heat pump repair services Tyson’s Corner.
