Where’d the Heat From My Heat Pump Go?


It has been quite chilly in Turlock, and the temperatures will remain quite low for several more weeks before spring arrives. However, you might be finding yourself feeling colder than you should despite your heat pump making sure that the indoor temperatures are warm and cozy – or maybe that is where the problem is.

Has your heat pump started blowing cold air in the middle of winter? Are you wondering where did the heat from your heat pump go? Several possible problems could be leading to the heat pump issues.

We are going to help you understand some of the reasons why your heat pump is working like an air conditioner in the middle of winter. And if you are looking for an HVAC contractor in Turlock to help you with repairs, do not hesitate to call us.

Why Your Heat Pump Isn’t Heating

Here are some of the possible reasons why your heat pump is not heating:

Clogged or dirty air filter

When you call in a professional to check why your heat pump is not heating, the first thing they might do is check whether the unit has a clogged air filter. When the air filter becomes too dirty because of dust and debris, the airflow entering the heat pump to be heated becomes restricted.

Air filters need to be replaced more than once a year to ensure proper airflow to the heat pump so it can blow warm air during the winters and cold air during the summers without any problems.

Faulty thermostat

Sometimes a malfunctioning thermostat could be sending the wrong signals to your heat pump and causing it to blow cold air instead of warm air. If there is a problem with your thermostat’s calibration or it is placed too close to a heating element, it will not signal the heat pump to maintain the heat level you need.

Additionally, a problem with the connection between your heat pump and thermostat could also stop the heat pump from changing over to heat mode.

Refrigerant leak

Heat pumps use refrigerant to function correctly because they rely on heat transfer to provide warm air instead of heating elements. The refrigerant absorbs heat from the surrounding air and transfers it indoors through the heat exchanger. If there is a leak that is causing refrigerant levels to go down, it can make the system inefficient, and it will not warm up your home.

Reversing valve troubles

The reversing valve mechanism in your heat pump allows the appliance to switch from cooling to heating mode in winters and from heating to cooling mode in the summers. The reversing valve changes the flow of the refrigerant to make this happen. If the valve breaks and gets stuck, your system cannot switch modes. A professional HVAC technician has all the right tools, training, and equipment to safely replace the valve.

Do Not Delay Repairs

If your heat pump is blowing cold air in the winters, you should not delay calling in a professional for repairs. A certified HVAC technician has all the right tools, training, and expertise to address the problem quickly before it becomes far worse.
