What Happens When A Heat Pump Fails?

Comfort means having a preferred temperature in your home. A heat pump system can help you to save energy and money without compromising the comfort of your home. Heat pumps are major components of an air conditioning system that can give warmth and cold to your surroundings. The HVAC system uses electrical energy to convert heat into cooling air and vice versa. During the winter season, there is still significant heat on the outside and the heat pumps can take it into the inside of your home to add additional warmth.

These pumps use a reverse cycle principle in their operation that’s why it is also called reverse cycle refrigeration. This HVAC component supports the system when it needs an additional source for the heating air or cooling air. What will you do when the heat pumps have difficulty on functioning? There are different factors that you must check to determine the problem.

Heat Pump Problems: Ice Build Ups

During the winter season, it is common that the heat pump’s outside unit may be covered by a layer of icy frost on the sides. You can easily remove those build-ups by setting the unit into defrost mode. According to the mechanical engineers, it is important to conduct a regular checkup on the top side of the unit to avoid any heavy-coated ice because it can damage the fins, blades, and compressors.

Heat Pump Problems: Running Constantly

During the summer season, your heat pump might constantly run especially if it’s struggling on supplying the desired cooling air in your home. But if it doesn’t provide cooling air then you must check the compressor. Conducting maintenance on the heat pump’s coil can remove the dirt and allow the cooling air to freely distribute in the surroundings. If you notice that the unit keeps on running even during the cold season, check the AC mode of the system and make sure that you set a proper temperature on the thermostat.

Heat Pump Problems: Heat Pump Is Making Much Noise

If you are hearing unwanted noise from the heat pumps, it may indicate a problem with the motor’s bearing. Rattling noise tells you that the cover of the panels might not be locked properly. Check the screws immediately as well as the loose parts on the air handler. 

Metal noise is commonly caused by heating ducts. This can be avoided by inserting flexible insulation into the ducts. While the Pinging sounds are the result of thermal expansion. You can make a small dent on the metal to give way to the air pressure.
