Why Your Heat Pump Isn’t Working In Cold Weather

If you have a heat pump, you may notice that it’s having trouble operating in cold weather.

Since heat pumps don’t work quite like furnaces, heat pumps may have some issues during spats of cold weather. Depending on your problem, we may be able to figure out how you can get your heat pump working again.

My Heat Pump Isn’t Defrosting or My Heat Pump is Frozen

A little bit of outer frost is normal as condensation on the heat pump freezes.

However, the heat pump has a defrost mode where it melts the ice that forms on top. If the frost continues and starts spreading to the rest of the unit, you have an issue that a technician needs to fix.

If your heat pump is completely frozen, then you have a serious issue and you need to get a technician to your door ASAP.

My Heat Pump Is Blowing Cold Air

First thing you want to do is check your thermostat settings. You may have turned on AC mode by mistake.

If you feel cold air coming from your vents, but you don’t quite notice a change in temperature throughout the house, it might not be an issue at all. You might simply be feeling your home maintaining the current temperature.

But if your thermostat is registering a cold temperature, you’re going to want to get a technician.

Heat Pump Draining Issues

If you’re seeing dripping from your heat pump, then a draining issue is likely present.

This could be the result of your heat pump being submerged in snow during a storm, exposed to a great deal of precipitation, or simply being on an unsteady surface.

This might not be a big problem in the short term, but if you notice constant dripping, then you should get a technician in to fix the issue.

My Heat Pump Is No Longer Working At All in Cold Weather

Your heat pump should be running 24/7. If it ever turns off, it should be a cause for concern.

First check if anyone could have turned it off manually. It’s a common misconception that they need to turn off.

Heat pumps don’t need to turn off to maintain energy efficiency because they operate at ⅓ the energy of an electric furnace.

Call an HVAC technician to schedule an appointment, because your heat pump is likely having issues.

What Should You Do? Follow These Steps

First, log what issues you’re having. If you’re having just one of these issues, it might not be much of a problem at all. But if you’re having several of them, then your heat pump might need repair or replacement.

Second, call an HVAC technician and explain your issues. They will be able to diagnose the problem and decide whether or not you need heat pump repair or replacement.
