How to Troubleshoot a Heat Pump That Is Blowing Cold Air


Is your heat pump blowing out cool air? A heat pump is a unique heating and cooling system that uses a process of energy conversion to provide warm and cool air during the prospective warming and cooling seasons. It does this by sucking in the air from the outside atmosphere and condensing it, so that it emits the temperature you dictate to the thermostat. Oftentimes, they use very little energy, which makes them much more efficient than traditional central heating and air conditioning systems. However, if you start experiencing an issue where your heat pump distributes cold air, it is important to find the culprit before you call a service technician. Here is how to troubleshoot a heat pump that is blowing cold air.

For one thing, your heat pump may not be blowing out cold air. How is this possible? Well, the air may feel cold, but it could just be that you aren’t used to your new heat pump. If you made the switch from a central heating system or furnace, you may be used to hot air coming out of your ducts. However, a heat pump will emit what feels like lukewarm air. It is still warming up your home, but it may be colder than what you are accustomed to.

Another issue may be that your outdoor compressor unit is not working. If the compressor isn’t bringing in air, your system won’t be able to compress and condense air. It could be that there is debris in the fan unit – leaves and branches could be causing the fans to stop working. All you would have to do is shut down your entire system and then pull out the debris. Another issue may be that the compressor unit is frozen – you may want to run the fan until the ice is melted. You may also want to place a cover on your compressor unit and wait for the ice and snow to melt.

Next, you may be having an issue with leaks in your ductwork. Basically, as the warm air travels, it escapes through the leak. When the air finally reaches the registers in your home, it is cold to the touch. If this is the case, you may have to opt for professional duct sealing. If your ductwork is particularly old, you may have a few different leaks that are virtually imperceptible. A professional technician will be able to find the leaks and then seal them – using the proper tools and materials, of course.

In the end, a heat pump that is bringing cool air into your home, versus warm air, is a heat pump that is not doing its job correctly. If the weather outside is particularly cold, you will want to get to the bottom of this issue right away – your comfort and well-being could be at stake. The issue could also be a warning that there is a larger problem that will only get worse if you don’t take action. In the end, you want to take action instead of doing nothing at all.
