Don't Fall for These Common Geothermal MythsWhen you want the most energy efficient HVAC system available, don’t let these geothermal myths deter you. Not only are geothermal heat pumps (GHPs) the most energy efficient kind of HVAC system, they’re also the quietest and most durable option available. 

  • Myth: They don’t use renewable energy. Conditioning a home takes tremendous amounts of energy, and while a GHP does use electricity, it uses far less than any other kind of HVAC system. Their efficiency stems from renewable underground energy transfer. Temperatures below ground change little year-round, unlike air temperatures that have wide temperature swings, which increase the burden on traditional heat pumps and air conditioners.
  • Myth: They require a large yard. Instead of placing the loop field the GHP uses to exchange heat below ground horizontally, the loop field can be placed vertically in a deep trench when yard size is limited.
  • Myth: They’re too expensive. This is one of the most persistent geothermal myths. In fact, the accrued energy savings alone will pay for a GHP. The federal government is also offering a tax credit to offset the cost of a new system. The credit covers 30 percent of the cost of most of the installation and equipment, and it’s in place until December 31, 2016.
  • Myth: They wear out. Because they have fewer moving and exposed components, you can expect the indoor part of the GHP to last 25 years and longer with adequate maintenance. The loop field typically carries a 5- year warranty. An above-ground HVAC system has a typical system life from 12 to 17 years.
  • Myth: GHPs only heat and cool air. If equipped with a desuperheater, you can use a GHP to supply some of the heat for your water heater in the winter. In the summer, it can heat a pool, a hot tub and all of your home’s water. A water heater ranks second as the appliance that uses the most energy in your home, after your HVAC system.
