Maintaining Your Geothermal Heating and Cooling System in Western Montana

One of the greatest things about heating and cooling your Western Montana home with a geothermal system is the minimal maintenance required of you. The system’s relative simplicity is reason enough that. But minimal maintenance isn’t the same as no maintenance. Keeping your system operating smoothly and efficiently necessitates routinely checking the heat pump’s fluid levels and temperatures as well as cleaning or installing new filters in both the air handling unit and the geothermal ground-loop system. In addition to that, once-a-year maintenance service should be provided by the registered, qualified geothermal energy engineers at Ground Source Systems, Inc.. These complementary efforts – yours and ours – can ensure that your compressors and circulation pumps hang in there for a good 35 to 50 years, the adjudged life of your geothermal system.

Make it a point to consult your owner's manual for proper maintenance procedures. Suffice it to note here that examining fluid levels as a rule means 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 need changing regularly: 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. In the main, HEPA filters are installed, but there are other kinds of reasonable filters that can be good for allergy sufferers.

Most geothermal system air filters are disposable. Change them every three months. Permanent filters, which are cleanable with a vacuum-cleaner hose, should be taken out of the housing and cleaned every one to three months. Whether cleaning or replacing, it’s critical that you wear rubber gloves, eye protection, and a face mask that covers your mouth and nose. It’s even more critical, however, that you unplug the system from all power sources beforehand!
