Maintaining Your Geothermal Heating and Cooling System in

One of the niceties of heating and cooling your home with a WaterFurnace geothermal system is the minimal maintenance required of you. The system’s relative simplicity accounts for that. Nevertheless, minimal maintenance doesn’t mean no maintenance. Keeping your system’s operation smooth and efficient calls for 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, yearly maintenance service should be provided by the registered, qualified geothermal energy engineers at Ground Loop Heating & Air Conditioning, Inc. These complementary efforts – yours and ours – can insure that your compressors and circulation pumps hang in there for a solid 35 to 50 years, the reckoned life of your WaterFurnace geothermal system.

Make sure you consult your WaterFurnace Operation and Maintenance (O&M) manual for details on the proper maintenance procedures. Suffice it to note here that checking fluid levels as a rule means checking on the amount of refrigerant needed to operate the geothermal heat pump.

There are in fact two filters in the air handling unit that have to be changed every now and then: one in the discharge ducting, the other in the air return system. Both filters capture airborne particles sucked in from all over your home; particles like dust, fluff, dust mites, insects, and smoke residue. Usually, HEPA filters are used, but there are other types of satisfactory filters that can be beneficial for allergy sufferers.

Geothermal system air filters are most often 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 necessary that you put on rubber gloves, eye protection, and a face mask that covers your mouth and nose. It’s even more crucial, in any event, that you isolate the system from all power sources beforehand!
