Maintaining Your Geothermal Heating and Cooling System in Knox County

One of the nicest things about heating and cooling your Knox County home with a WaterFurnace geothermal system is that it requires so little maintenance. The system’s relative simplicity explains that. But minimal maintenance doesn’t mean no maintenance. Keeping your system running smoothly and efficiently does entail 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. Beyond that, yearly maintenance service should be provided by the registered, qualified geothermal energy engineers at Cosby Heating and Cooling. These dual efforts – yours and ours – can help guarantee that your compressors and circulation pumps hold up for a good 35 to 50 years, the guesstimated life of your WaterFurnace geothermal system.

By all means, consult your WaterFurnace Operation and Maintenance (O&M) manual for information on the right maintenance procedures. It’s enough to note here that inspecting fluid levels on the whole involves 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 must be changed periodically: one in the discharge ducting, the other in the air return system. Both filters help eliminate airborne particles picked up throughout your home; particles on the order of dust, fluff, dust mites, insects, and smoke residue. Generally, HEPA filters are used, but there are other sorts of acceptable filters that can be good for those troubled by allergies.

Geothermal system air filters are most often disposable. Replace 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 fits over your mouth and nose. It’s even more crucial, however, that you disconnect the system from all power sources beforehand!
