Maintaining Your Geothermal Heating and Cooling System in Pittsburgh

One of the best things about heating and cooling your Pittsburgh home with a WaterFurnace geothermal system is the minimal maintenance required. The system’s relative simplicity is reason enough that. But minimal maintenance shouldn’t be taken to 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 swapping out filters in both the air handling unit and the geothermal ground-loop system. Aside from that, once-a-year maintenance service should be provided by the registered, qualified geothermal energy engineers at E & D Company HVAC LLC. These twin efforts – yours and ours – can make certain that your compressors and circulation pumps keep going for a solid 35 to 50 years, the approximated life of your WaterFurnace geothermal system.

See to it that you consult your WaterFurnace Operation and Maintenance (O&M) manual for details on the right maintenance procedures. It’s enough to say here that checking fluid levels essentially means checking on the amount of refrigerant required to operate the geothermal heat pump.

There are in fact two filters in the air handling unit that require changing every now and then: one in the discharge ducting, the other in the air return system. Both filters capture airborne particles picked up throughout your home; particles such as dust, fluff, dust mites, insects, and smoke residue. Ordinarily, HEPA filters are employed, but there are other kinds of acceptable filters that can be good for those racked with allergies.

The most common geothermal air filter is the disposable kind. Switch them out them every three months. Permanent filters, which you can sanitize 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 wear rubber gloves, eye protection, and a face mask that shields your mouth and nose. It’s even more critical, in any event, that you cut the system off from all power sources beforehand!
