Why Is My Heat Pump Freezing Up?

When your heat pump freezes up and stops working the way it should, you probably feel a mix of frustration and alarm.

And no matter what the problem is, our team can get down to the root cause and fix it so that your heat pump works the way it should again. Just give our team a call to schedule heat pump repair in Eugene. You can also keep reading to learn more about why your heat pump may be freezing up and what can be done about it.

Stuck Reversing Valve

Many times when it seems like your heat pump is not working, the heat reversing valve is actually to blame. The reversing valve is what allows your year pump to move between heating and cooling functionality. Sometimes the valve can get stuck in one direction and won’t switch modes. If this is the problem, it’s an easy fix to make.

Faulty Sensors

Your heat pump has a variety of sensors and safety mechanisms inside to ensure proper operation. But if the sensors are faulty, they may signal for your heat pump to stay off when nothing is wrong. For example, there are defrosters on the outdoor unit to prevent ice buildup from developing during the winter season. 

If the defrosters are malfunctioning, your heat pump may not be working the way it should. Our team can test and fix any sensors inside of your heat pump. That way, they can operate the way they were intended to keep your home safe while also allowing your heat pump to operate the way it needs to for heating.

Miscalibrated Thermostat

Sometimes, your heat pump isn’t actually the problem at all. Instead, your thermostat may be to blame for your heat pump freezing up and not working. If your thermostat is not reading the indoor air temperature accurately or communicating with your heat pump, your heat pump may not turn on for a cycle when it needs to. 

When this happens, we can troubleshoot your thermostat and try things like cleaning it out, changing the batteries, and recalibrating it. If none of these things work, your thermostat may have simply reached the end of its life and need to be replaced.

Low Refrigerant Levels

Your heat pump needs refrigerant both for heating and cooling. Without enough refrigerant charge in the lines, your heat pump will not be able to keep up with heating your home this winter season. Low refrigerant levels mean that you have a refrigerant leak somewhere that needs to be fixed. Our team can take care of this if it is a problem and then recharge refrigerant levels so that they are adequate for heating and cooling your home.
