Maintaining Your Geothermal Heating and Cooling System in Wilmington

One of the beauties of heating and cooling your Wilmington 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 necessitates periodically 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. Aside from that, yearly maintenance service should be provided by the registered, qualified geothermal energy engineers at O'Brien Service Company. These complementary efforts – yours and ours – can help guarantee that your compressors and circulation pumps endure for a respectable 35 to 50 years, the estimated life of your WaterFurnace geothermal system.

By all means, consult your WaterFurnace Operation and Maintenance (O&M) manual for proper maintenance procedures. It’s enough to tell you here that checking fluid levels primarily means checking on the amount of refrigerant required to use the geothermal heat pump.

There are actually two filters in the air handling unit that have to be changed every so often: one in the discharge ducting, the other in the air return system. Both filters catch 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 sorts of satisfactory filters that can be helpful to those suffering from allergies.

Disposable geothermal system air filters are the norm. Switch them out 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 important that you don rubber gloves, eye protection, and a face mask that covers your mouth and nose. It’s even more vital, in any event, that you isolate the system from all power sources beforehand!
