Homes with larger heating and cooling loads require larger heat pumps — and sometimes even more than one. The larger the heat pump or the most heat pumps needed , the greater the cost.
A geothermal heat pump contains 3 primary components: a heat exchanger that interacts with the outdoor ground loop, a compressor, and a heat exchanger that interacts with the indoor ductwork or hydronic distribution system.
Homes with ductwork located in the attic or with low-ceiling basements generally require a split system. Split systems are more complex to install than packaged units. They have the added benefit, however, of more flexibility with respect to where the heat pump and air handler are located in your home. Homes with multiple zones are divided into areas that each have their own individual temperature control. Duct zoning provides more granular temperature control in sections of the home e. This increase is sometimes minor and relatively common, so the cost will be lower.
Some homes require a significant increase, however, which comes at a cost premium. If a property is exceptionally rocky or the bedrock is relatively high, some rocks may need to be drilled around, drilled through, or removed entirely.
The system and supplies make up the rest of the price. The outdoor portion of your heat pump lasts up to years, depending on conditions, and likely will not need replacing during your lifetime. The indoor portion of the system may need to be replaced, but only after decades of use. All HVAC systems have varying degrees of efficiency, meaning how much energy they use to produce heat. Because heat pumps provide both heating and cooling, they have two different efficiency ratings, one for each.
The Coefficient of Performance COP for heating is the measurement of how well the unit uses energy to heat the home. A geothermal heat pump has a COP of 3 to 5, meaning that for every unit of electricity it consumes, it produces 3 to 5 units of heat.
This is much more efficient than other systems, which may have COPs of just 1 or 2 in very high-efficiency systems. The higher the EER on a cooling appliance, the more efficient it is at cooling your home. Geothermal heat pumps have an EER from 13 to Anything above an EER of 12 is considered high efficiency, which makes all geothermal heat pumps high-efficient cooling appliances.
Like any system, a wide range of factors affect the total system cost. These include location, climate, energy efficiency of your home, soil type, yard space, install location, and whether this is a new installation or a retrofit.
If you need ducts installed or have steam radiators, your costs are higher than if you already have usable ducts in your home. Geothermal heat pumps are much more efficient to run than other heating systems. According to Energy. Geothermal heating is one of the most energy-efficient heating and cooling methods used for your home regardless of climate.
This method sees savings year-round over other types of heating and cooling systems. Geothermal heating is also better for the environment because it does not directly use fossil fuels and uses less electricity than other systems. Therefore, it does not contribute as much to greenhouse gasses. It is also safer with no risk of carbon monoxide or gas leaks, and you do not need to store additional fuel on your property like oil or propane. In addition, if a desuperheater is added, you may also use the system to heat your hot water.

It is more complicated to install with additional thermostats, a zone control board, and dampers. Adding more insulation to your home increases energy efficiency, which means that you may use a smaller-sized system. Making your windows more energy efficient also lowers heating and cooling costs. The average cost to install geothermal heating and cooling in a 2,sq.
It uses some but not as much as other types of HVAC systems. It may, depending on the area where you live. It saves money on energy bills, which is attractive to some buyers. Yes, retrofits are available and common. Their total cost depends on whether you have existing ducts or not.
This depends on the system type. Vertical systems do not use much space, so they may be used in homes with smaller yards. Cost to install a geothermal heating system varies greatly by region and even by zip code. To get free estimates from local contractors, please indicate yours.

Additional Considerations and Costs Geothermal systems are very eco-friendly and are becoming more popular with homeowners investing in the green building movement. You need a permit from your local municipality to install this system, and some system types may have additional regulations.
There might be a long wait involved if there are regulations that need to be followed. The system is installed using either drilling or trenching equipment, depending on the system type.
Horizontal systems require trenching, while vertical systems require drilling. Installation is very disruptive to lawns and landscaping. The heavy equipment must be able to reach the site and may dig up more landscaping than the actual installation. Many types of hybrid systems are available, including geothermal and air pump combinations, for those in more moderate climates.
You do not need backup heat with a geothermal system, but some people in moderate climates may choose to use a smaller system with a backup option for the coldest days of the year to save money. Geothermal systems last years with little to no maintenance, making them a good investment for any home. While you may use geothermal heat pumps with a radiant heat system, they do not work with steam radiators. A standard heat pump lasts 10 to 15 years.
