Heat pumps are designed to keep your house both warm and cool during the winter and summer seasons respectively. It operates slightly differently than traditional air-cooled air conditioners. This means that if you need heat pump repair, the fix would be a bit tricky as well. However, do not worry, we have gathered a list of some common problems with heat pumps along with their solutions for you to consider. Let’s begin!
Heat Pump Icing Up
During the winter season, your heat pump outside will be covered with snow and frost, which is quite normal. If the situation becomes extreme, the heat pump will automatically go into defrost mode to remove some ice. However, if you notice that the heat pump is covered with a thick ice foam and the internal components such as the condenser and evaporator coils are also hidden under ice, it indicates a problem.
The reason is that the ice interferes with the transfer of heat between the outside air and the refrigerant. As a result, the overall performance of the heat pump is affected. You should immediately fix the situation instead of ignoring it. If internal components remain covered with ice, it might end up damaging the unit beyond repair.
To solve the issue, your heat pump will periodically switch to the air conditioning mode to heat up the evaporator as well as the condenser coils. If the defrost mode does not set in, the ice will build up rapidly. Generally, defrost issues can be caused by sensor, controls, or relay issues.
Furthermore, it might also be that the outdoor fan is malfunctioning. As a result, it will impede the release of heat from the unit, causing ice to accumulate. In addition to that, you might also want to check the refrigerant level. If it happens to be low or leaking, the system will not be able to produce enough heat to melt the ice.
Finally, you should check the outdoor unit if it is blocked. Tree shrubs, leaves, and other items may get stuck inside hindering the performance of the unit. Regular cleaning and maintenance of your heat pump will help avoid the issue.
Heat Pump Running Constantly
Another problem heat pumps encounter is that they keep on running constantly. This is mostly the case during the summer season when the heat pump is struggling to reach the set temperature. However, if you notice that the weather isn’t too hot and the HVAC is still not producing cool air, you might need to call in a professional for service.
However, before you make the call, make sure the appropriate temperature is set and there is nothing troubling the unit. Sometimes, the problem can be identified with a naked eye but others could be extremely minor. In this case, a professional will thoroughly check the unit and fix the root cause of the problem.
The same is the case with winters. Even though heat pumps will run for hours before taking a break, but if you notice that the temperature outside is not that cold and the unit keeps running, you might want to get your HVAC serviced. There could be several reasons causing the problem and it is important to fix them as soon as possible.
Blowing Cold Air In Heat Mode
If you notice that your heat pump is blowing cold air in heat mode, you should first check the settings. It might be that someone has accidentally changed the setting to A/C mode. If that is not the case, you should check the outdoor unit for icing. If even that is not the problem, you should check the compressor, refrigerant level, or valve.
If your unit happens to be new, chances are that it needs maintenance. However, if it is an older unit, you might want to consider the compressor inspection and annual maintenance.
Heat pumps irrespective of being old or new will encounter problems sooner or later. This is why it is important for you to be aware of the basics mentioned above along with their fixes to ensure the unit keeps running flawlessly especially when it is freezing outside.
