Reasons Why Your Heat Pump Is Blowing Cold Air
There is nothing worse than waking up on a winter morning and realizing that the heating is not working like it should be. If your heat pump is not working, you have felt this uncomfortable situation before. Heat pumps blow cold air for several reasons. Look at our list below to help figure out why your heat pump is blowing cold air.
- Dirty Outdoor Unit – The outdoor unit of your heat pump is vital to maintaining the temperature inside your home. If outdoor unit is clogged, dirty, or blocked, this could be causing it to blow cold air. Ensure your unit is clean and free of blockage or debris.
- Thermostat Settings – We realize this one may seem a little obvious, but often when folks experience a heat pump blowing cold air, they forgot to switch it to the heat setting. Always double check your thermostat if you notice cold air coming.
- Automatic Fan Setting – If you heat pump’s fan is set to ON, it will blow air regardless if it has been heated or not. By switching your fan over to AUTO, your heat pump will only blow in air that has been sufficiently warmed.
- Valve Issues – Unlike furnaces, heat pumps have a valve that changes the pump from cooling to heating mode. If this reversing valve is malfunctioning, it can cause cold air to blow from your heat pump. If you have eliminated the other potential problems, the reversing valve may be the problem.
- Refrigerant Levels – A heat pump contains refrigerant that traps the heat from the air outdoors and brings it into your home. Leaking refrigerant will mean the pump is unable to absorb the necessary amount of heat for your home.
When Your Heat Pump Is Not Heating, Don’t Try DIY
While we have suggested a few reasons that your heat pump might be putting cold air into your home, it is advisable that you call your HVAC company to fix it. Attempting DIY repairs on a heat pump can often lead to even more damage or problems, and an even bigger repair bill.
