Heat Pump Outdoor Maintenance
Tasks such as replacing the filters and lubricating as well as cleaning the parts of the heat pump are important. Moreover, the outdoor unit containing compressor, fan, coil etc. must not have dirt or leaves either for proper functioning.
Before trying to do any kind of cleaning, you should disconnect the pump from main power. Dirt, leaves, and pine needles are to be cleaned by detaching the grille. For cleaning the bottom and sides of the unit, vacuum hose can be inserted at times between two fan blades.
When heating season begins, setting carpenter’s level across the metal cabinet top, and checking the level from back to front, and side to side can help a lot. If you find that the unit is not level on the pad, be sure to lift the pad in order to level it by prying it up by using a 2-by-4 piece, or pry bar. Build the underneath ground with crushed rocks or stones. Moreover, detect if there is any deterioration in the insulation of the piping, and replace the same if required.
Tackling Power Interruptions
In case blown fuse, utility power failure, or tripped circuit break occurs, and the pump gets off for longer than one hour, it is best to not operate the heat pump for the next six or eight hours, particularly if the ongoing temperature is below 50 degrees.
The lubricant inside the oil reservoir of the pump may be really cool, and not circulate in a proper way, which can result in valve damages. Hence, setting the heat pump on emergency heat and turning it off to prevent running it is a good idea. The pump should be kept like this for about seven or eight hours, and then switching it to the normal settings should work. If the generation of heat is too low after this episode, be sure to call a technician for proper repair.
