Maintaining Your Geothermal Heating and Cooling System in Alaska

One of the nicest things about heating and cooling your Alaska home with a geothermal system is the minimal maintenance needed. The system’s relative simplicity accounts for that. Nevertheless, minimal maintenance doesn’t mean no maintenance. Keeping your system’s operation smooth and efficient necessitates regularly 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 Energy Efficiency Associates. These binary efforts – yours and ours – can make certain that your compressors and circulation pumps keep going for a solid 35 to 50 years, the reckoned life of your geothermal system.

Make sure you consult your owner's manual for proper maintenance procedures. It’s enough to note here that inspecting fluid levels on the whole occasions checking on the amount of refrigerant necessary to run the geothermal heat pump.

There are in fact two filters in the air handling unit that have to be changed periodically: 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 like dust, fluff, dust mites, insects, and smoke residue. Ordinarily, HEPA filters are employed, but there are other kinds of satisfactory filters that can be helpful to allergy sufferers.

Disposable geothermal system air filters are the most common. Change them every three months. Permanent filters, which you can clean with a vacuum-cleaner hose, should be pulled 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 fits over your mouth and nose. It’s even more critical, in any event, that you cut the system off from all power sources beforehand!
