Geothermal comfort system
March 10, 2015
The new system combines a variable capacity compressor with a variable speed blower motor and a variable speed loop pump to provide energy-efficient comfort, while protecting the environment. The use of variable technology allows the unit to scale output to exactly the level needed, rather than running at one or two speeds, like the majority of HVAC systems. Available in three- to five-ton capacities.
