Maintaining Your Geothermal Heating and Cooling System in Manhattan

One of the nicest things about heating and cooling your Manhattan home with a geothermal system is that it demands so little maintenance. The system’s relative simplicity explains that. Nevertheless, minimal maintenance shouldn’t be taken to imply no maintenance. Keeping your system operating 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, annual maintenance service should be provided by the registered, qualified geothermal energy engineers at Carlson Heating & AC, LLC. These twin efforts – yours and ours – can help guarantee that your compressors and circulation pumps last for a good 35 to 50 years, the calculated life of your geothermal system.

See to it that you consult your owner's manual for correct maintenance procedures. Suffice it to say here that investigating fluid levels as a rule means checking on the amount of refrigerant necessary to run the geothermal heat pump.

There are in fact two filters in the air handling unit that need changing regularly: one in the discharge ducting, the other in the air return system. Both filters catch airborne particles sucked in from all over your home; particles on the order of dust, fluff, dust mites, insects, and smoke residue. In general, HEPA filters are installed, but there are other kinds of satisfactory filters that can help allergy sufferers.

The most prevalent geothermal air filter is the disposable kind. 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 necessary that you put on rubber gloves, eye protection, and a face mask that covers your mouth and nose. It’s even more critical, however, that you disconnect the system from all power sources beforehand!
