One of the nicest things about heating and cooling your Manhattan home with a geothermal system is that it demands so little maintenance. The system’s relative simplicity explains that. Still, minimal maintenance shouldn’t be taken to mean no maintenance. Keeping your system operating smoothly and efficiently does entail routinely checking the heat pump’s fluid levels and temperatures as well as changing filters in both the air handling unit and the geothermal ground-loop system. Beyond that, yearly maintenance service should be provided by the registered, qualified geothermal energy engineers at Carlson Heating & AC, LLC. These complementary efforts – yours and ours – can make certain that your compressors and circulation pumps last for a solid 35 to 50 years, the adjudged life of your geothermal system.
See to it that you consult your owner's manual for proper maintenance procedures. Suffice it to say here that inspecting fluid levels mostly involves checking on the amount of refrigerant necessary to utilize the geothermal heat pump.
There are in fact two filters in the air handling unit that have to be changed regularly: one in the discharge ducting, the other in the air return system. Both filters catch airborne particles sucked in from all over your home; particles on the order of dust, fluff, dust mites, insects, and smoke residue. Commonly, HEPA filters are installed, but there are other kinds of decent filters that can be helpful to those afflicted with allergies.
Geothermal system air filters are most often disposable. Replace them every three months. Permanent filters, which you can refresh with a vacuum-cleaner hose, should be removed from the housing and cleaned every one to three months. Whether cleaning or replacing, it’s necessary that you put on rubber gloves, eye protection, and a face mask that covers your mouth and nose. It’s even more crucial, however, that you disconnect the system from all power sources beforehand!
