Ground Source, or Geothermal, heat pumps use the earth to transfer energy between your house and the ground, which makes for an efficient heating and cooling system. By transferring energy, instead of creating it, Geothermal HVAC systems are more efficient than traditional gas furnaces. Geothermal heat pumps provide precise temperature control at extremely efficient rates, regardless of the season. Unlike conventional heat pumps, the efficiency and capacity of a geothermal system are not affected by outdoor temperature changes.
A geothermal system consists of a heat exchanger (the 2,000 to 6,000 feet of piping buried or drilled into the ground), the ductwork (needed for most systems), and the indoor unit (just like a furnace or an air handler). We would typically recommend installing 2,000+ feet of pipe in the ground, a less expensive option. If this much space is not available, then we can drill 200 foot wells into the ground and run piping through the wells or drill horizontally under the house. Ables has options for all lot sizes, ranging from 50 X 100 (5,000 sq foot city size lot) to houses on acreage.
Reduce energy expenses with geothermal heat pumps
Geothermal HVAC systems currently qualify for a federal tax credit that encompasses 30% of the installed cost. Geothermal heat pumps can save 60% of your heating and cooling costs versus a gas furnace and air conditioner, or about 40% of your heating and cooling costs versus a high efficiency heat pump.
Most geothermal systems will also provide you with about a third to half of your water heating needs while heating and cooling your home. This could save you another $100-$300 per year in utilities. The excavation needed may be a significant portion of the costs associated with the system as well as the size and scope of the system, but Ables Heating, Cooling and Electrical will also get this setup for you if needed.
Geothermal systems can be installed in almost any house, but costs are highly variable. Call Ables Heating, Cooling and Electrical for more information on geothermal heat pump installation and to schedule a site visit. If geothermal isn't for you, we can make strong recommendations for a new or replacement HVAC system that fits your indoor comfort needs.
