Geothermal & Solar Systems

Geothermal systems get most of their energy from the consistent temperature of the earth. In our northern climate, the earth remains a constant 50 to 55 degrees year round.

In the winter time, this heat is absorbed by the loop system and carried into the geothermal furnace where it is compressed to a higher temperature. The result is a warm and comfortable home.

In the summer time, the process is reversed. The warmth of the air in the home is absorbed by the geothermal furnace and deposited into the cooler earth through the loop system. The result is a cool, dehumidified, comfortable home.

While heating and cooling the home, some geothermal furnaces can capture excess heat and use it to heat hot water for your domestic use.

  • Efficient – 1 unit of electricity combined with up to 4 units of energy from earth = effective 500% efficiency.

Solar HVAC Systems

With utility costs on the rise, it’s good to know that you can integrate solar energy into your home, and that it can substantially reduce your heating and cooling costs, which typically make up about half of your home’s utility bill.

Solar modules capture energy from the sun, and send it to your Lennox solar-ready air conditioner or heat pump. That energy is first used to heat or cool your home. Energy that is left over is used to power electronics and small appliances in your home. If energy is still left over, it can potentially be sold back to your utility company, and possibly earn you a credit! If that isn’t enough, there is a 30% federal tax credit on solar as well as a 9% federal tax credit on your Lennox solar bearing equipment. Please contact us for more information!
