Geothermal systems use the relatively constant temperatures underground to provide efficient, year-round energy for heating, cooling and water heating. Also known as ground-source or earth-coupled heat pumps, geothermal systems are typically the most cost-effective and environmentally friendly option available.

During winter, heat pumps transfer heat from the cold outdoors to deliver warmth into your home. During the summer, they do the opposite. Because heat is moved instead of generated, heat pumps are able to provide up to four times the amount of energy they consume.
According to the Department of Energy, air source heat pumps are the most common heat pump. With this type of heat pump, the heat is transferred between your home and the outdoor air. If you use electricity for heating, an air source heat pump can reduce the amount of electricity used for heating by 30 to 40 percent on average.

A central air conditioner cools and dehumidifies your home. The system includes an indoor unit and an outdoor unit. The indoor unit uses refrigerant to remove heat and humidity from the air at the cooling coil. It then transfers the heat outside where it is released via the outdoor unit. The indoor unit also connects to your home’s ductwork and uses a furnace blower fan to circulate indoor air. The fan pushes the cooled air through the ducts and into rooms via supply vents, while drawing warmer room air back through return vent(s).

A furnace blower circulates air throughout your home. During heating season, your furnace heats the air and the blower pushes the heated air – typically to vents through ductwork – to ensure your home reaches the temperature set on your thermostat. There are several types of blower motors to choose from, but an electrically-commutated motor (ECM) offers the highest efficiency and energy savings. The ECM can also circulate cold air throughout your home during cooling season if you have a combined central air conditioning system.
An air source heat pump system absorbs heat from the outside air, even extremely cold air, and moves it into your home during heating season. The system uses a compressor to circulate refrigerant between two heat exchanger coils (one outside, one inside). Seasonal adjustments can be made, reversing the process during cooling season to absorb heat in the home and move it outside. Thus, an air source heat pump system provides your home with both heating and cooling options.
Ductless mini-split heat pumps are a heating solution for homes that do not require ductwork. The system uses a compressor pump to circulate refrigerant liquids between two heat exchanger coils (one outside, one inside). The indoor unit(s) is located directly in the living space of your home. By eliminating the need for ductwork to/from vents, system efficiency increases because heated or cooled air isn’t lost through duct leaks.
Geothermal heat pumps are a ground system which use the earth’s temperature to produce reliable and cost-effective energy for heating, cooling, and/or water heating. Geothermal systems take advantage of the relatively constant below-ground temperature, utilizing pipe buried in the ground (loop system) to extract or dissipate heat. During heating season, the heat exchanger transfers heat collected from the ground loop system to the indoor heat pump which transfers it into the indoor air delivery system to heat the home. This process is reversed during cooling season, removing heat in the home and transferring it to the ground.
