One of the niceties of heating and cooling your Denver home with a geothermal system is that it needs so little maintenance. The system’s relative simplicity accounts for that. But minimal maintenance isn’t the same as no maintenance. Keeping your system’s operation trouble-free and efficient necessitates 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. Aside from that, once-a-year maintenance service should be provided by the registered, qualified geothermal energy engineers at Denver Geothermal Heating. These dual efforts – yours and ours – can help guarantee that your compressors and circulation pumps endure for a respectable 35 to 50 years, the calculated life of your geothermal system.
By all means, consult your owner's manual for information on the correct maintenance procedures. Suffice it to note here that inspecting fluid levels as a rule involves checking on the amount of refrigerant necessary to run the geothermal heat pump.
There are actually two filters in the air handling unit that need changing periodically: one in the discharge ducting, the other in the air return system. Both filters help remove airborne particles picked up from all over your home; particles on the order of dust, fluff, dust mites, insects, and smoke residue. Ordinarily, HEPA filters are installed, but there are other sorts of acceptable filters that can help allergy sufferers.
Geothermal system air filters are typically disposable. Replace them every three months. Permanent filters, which are cleanable with a vacuum-cleaner hose, should be removed from the housing and cleaned every one to three months. Whether cleaning or replacing, it’s important that you put on rubber gloves, eye protection, and a face mask that fits over your mouth and nose. It’s even more crucial, though, that you cut the system off from all power sources beforehand!
