Geothermal & Air-Source Heat Pumps

An increasing number of Ft. Smith homeowners are installing geothermal, or ground source, heat pumps. These energy-efficient systems are an environmentally friendly way to heat and cool a home. Traditional air source heat pump and geothermal systems operate on the same principle of heat transfer.

Ft. Smith, AR Heat-Pump-ServicesWhile a traditional heat pump transfers warmth to and from the air, a geothermal system relies on the relatively stable temperature of the earth in order to generate its lower carbon footprint.

Despite its many benefits, there are times when a traditional air source heat pump is preferable to a geothermal system. Consider these differences if you need to install a new heat pump.

Energy Efficiency

Ground source heat pumps are more energy efficient for your Ft. Smith home. They operate between 300 and 600 percent efficiency, which compares to the 175 to 300 percent rating of an air source system.

This higher efficiency reduces the amount of energy required to produce the same level of comfort. Geothermal systems will save money on utility bills.

Upfront Costs

Geothermal heat pumps have a higher initial purchase and installation cost. This includes the need to excavate an area large enough to support the network of underground heat transfer pipes.

While a new Energy Star-qualified air source heat pump qualifies for a $300 tax credit, a geothermal heating and cooling system is eligible for an unlimited 30 percent credit. This added tax credit along with the increased energy efficiency can help defray the higher initial costs.

Maintenance on Your Heat Pumps

Air source heat pumps use an outside unit that is exposed to the elements. The unit requires regular cleaning. With a geothermal heat pump system, most of the components are underground or located inside where they are protected from the weather and possible damage.

While the average service life of the indoor component of an air source heat pump is 15 years, a geothermal unit may last up to 25 years.

Although you may save money over time with a ground source heating and cooling system, it may not be cost effective if you plan to move in the near future.

You will also need the space for the required underground pipes. Contact our office if you want more information on the features, benefits and differences of geothermal and air source heat pumps. We can help you determine which of these heating and cooling systems is right for you.
