While geothermal systems are generally considered to be the most efficient type of heating and cooling equipment available, their up-front cost is sizable when compared to standard heating systems.
It's important to weigh the initial costs and long-term savings when choosing a geothermal heat pump. There are two parts of the installation process to consider when calculating estimated costs.
The indoor portion
In order to determine the type and size of geothermal heat pump needed for your home, your HVAC contractor will consider:
- The heating and cooling load of the home, which determines the size of the heat pump required.
- The efficiency of the structure, including insulation levels and airtightness. Making improvements in the home's overall efficiency may lower the heating and cooling load, which allows for a smaller-sized system.
- Modifications to the existing ductwork may be required, although this is generally of minimal concern. Your professional HVAC contractor will be able to assist in determining any added installation costs.
The outdoor portion
This portion of the geothermal heat pump is comprised of the looping field, a series of pipes buried underground that transfers heat energy. Installation requires drilling, sometimes excavation, and the laying of piping material. The size and cost of the loop field depends on soil conditions and its thermal capabilities. Moving landscape or outbuildings increases costs, too. It's important to work with a seasoned, qualified geothermal expert to achieve an accurately sized looping field and indoor system, and expert installation.
