Frequently Asked Questions

  • What is a geothermal heat pump?

    A ClimateMaster geothermal heat pump is an electrically-powered system that uses the earth’s natural heat-storing capabilities to provide heating and cooling for a home or business space.

    Geothermal heating and cooling solutions provide excellent HVAC results while remaining extremely energy efficient and more environmentally friendly than other HVAC solutions. Gustave A. Larson is the leading wholesale distributor of ClimateMaster geothermal heat pumps and other parts and products. Contact us and bring advanced technologies to your customers!

  • How does a ClimateMaster geothermal heat pump work?

    ClimateMaster geothermal heat pumps function by using the constant earth temperature as an exchange medium instead of the temperature outside, as traditional systems do. Like all other types of heat pumps, ClimateMaster geothermal HVAC systems have the capacity to adequately heat both residential and commercial environments.

  • How is heat transferred between the earth and the home?

    The earth has the capacity to store and absorb energy. In order for the heat pump to use the energy stored in the earth, it has to extract the heat through liquid mediums, either an antifreeze solution or water.

    This liquid medium circulates through the ground through closed or open earth loops before getting transferred to the heat exchanger of the heat pump. From there, heat is distributed throughout your home or office space.

    During the summer, the entire process is reversed to provide cooling. The heat pump extracts heat from inside the building and transfers it to the earth. ClimateMaster manufactures high-tech geothermal heating and cooling systems suitable for your customer’s homes and offices. Contact Gustave A. Larson today and become a ClimateMaster Dealer.
