  • Roughly 75% to 80% of heat supplied comes directly from the earth itself and is clean, free and renewable.
  • Little or no CO2 emissions helps prevent global warming.
  • EarthPure® Ozone Safe refrigerant has higher efficiencies and zero ozone depletion for unprecedented environmental protection.
  • MERV 7 filter removes up to nine times more dust, lasts three times longer and captures nearly 100% of pollen and spores compared to traditional fiberglass air filters.

Homeowner Satisfaction

  • Easy to install: Tranquility® 22 Digital breaks barriers never attempted before in the geothermal industry in making it the easiest geothermal system to install, period. To recap, they include, plug-and-play, communicating thermostat & configuration, small footprint and quick loop connects.
  • Two-stage technology automatically adjusts itself to provide the optimum, consistent indoor air temperature regardless of outdoor weather extremes.
  • Variable-speed blower motor (standard) adapts to various duct systems for greater flexibility and helps even out hot or cold spots.
  • Insulated compressor compartment and interior cabinet, plus no noisy outdoor fans reduce noise.
  • Automatic alerts, simplified controls, and easy lift-out access panels make it easy to use and service.
  • Tin plated air coil resists corrosion for longer life and improves moisture removal capabilities for additional comfort.
  • Cabinets are heavy-gauge galvanized steel and epoxy powder coated for a durable and long-lasting finish.
  • The drain pan is stainless steel, both corrosion and stain resistant.
  • Geothermal heating and cooling has no flame, no odors, and does not produce dangerous fumes.
  • Tranquility® 22 is engineered for safety with compressor, overflow, and freeze protection, plus a shut-down switch and fault lockout.
