Maintaining Your Geothermal Heating and Cooling System in

One of the niceties of heating and cooling your home with a WaterFurnace geothermal system is that it needs so little maintenance. The system’s relative simplicity explains that. Still, minimal maintenance shouldn’t be taken to imply no maintenance. Keeping your system running smoothly and efficiently necessitates regularly checking the heat pump’s fluid levels and temperatures as well as swapping out filters in both the air handling unit and the geothermal ground-loop system. Beyond that, annual maintenance service should be provided by the registered, qualified geothermal energy engineers at Geothermal North. These dual efforts – yours and ours – can make certain that your compressors and circulation pumps last for a respectable 35 to 50 years, the adjudged life of your WaterFurnace geothermal system.

Make it a point to consult your WaterFurnace Operation and Maintenance (O&M) manual for proper maintenance procedures. Suffice it to note here that inspecting fluid levels principally involves checking on the amount of refrigerant required to use the geothermal heat pump.

There are actually two filters in the air handling unit that need changing every so often: one in the discharge ducting, the other in the air return system. Both filters help remove airborne particles picked up throughout your home; particles on the order of dust, fluff, dust mites, insects, and smoke residue. Usually, HEPA filters are used, but there are other sorts of acceptable filters that can be helpful to those racked with allergies.

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 crucial that you wear rubber gloves, eye protection, and a face mask that covers your mouth and nose. It’s even more crucial, in any event, that you unplug the system from all power sources beforehand!
