How to Service a Heat Pump

The maintenance of a wall-mounted pump must be performed annually by a qualified dealer. Complete maintenance includes cleaning filters and a complete inspection of the unit. During the inspection, the technician will also take the pressure reading of the refrigerant. Moreover, they will check the control circuit and verify all the electrical connections. If you can follow all these technical terms, you can do all these by yourself. Are you ready to do this, then let’s dive in!

First of all, make things clear. Do you use your heat pump all year round or use it for a particular season only? In this case, if you use your heat pump for all year round, I will recommend you to service the heat pump every year. On the other hand, if your heat pump is for seasonal use, servicing every two years will be okay.

At the initial stage, you have to first clean the filters so that they aren’t clogged. You can also make this job done by using your vacuum cleaner. Vacuum the filter of the pumps in every three months and ensure clean it properly. You also have to keep in an eye on the surrounding area. The growing leaves and weeds can also hamper the efficiency level of your pump. So, you have to cut them out too.

As I have exclaimed the actual time for doing all these, but if you haven’t cleaned your pump for a while, then don’t waste any time. You should call for service technicians.

  • Check for the filters properly at least once in a month. If needed, you should clean them and replace them.
  • Make sure to keep the outdoor unit clean. For this, you have to clean the top, bottom, sides, and the entire surrounding clean properly. Inspect these places properly and keep the ice, snow, and debris away from the front panel.
  • Maintain the cleanliness of the coils. In case if they have a thick layer of dirt, using a heavy-duty degreaser will boost the entire process of cleaning.
  • Keep the shrubs split from every side of the heat pump back at least 18 inches to ensure sufficient airflow and repair.
  • Flush the indoor condensate pot when utilizing the air conditioning. This is especially necessary whether the device is above or in a completed living environment, but a skilled service technician can really do it.
  • In some cases, you may have to oil the fan motors. So, oil mark those fans that are not sealed with the case permanently. Don’t try to detach any motors from the chassis.
