Coldflow has been engineering standard and custom refrigeration and air conditioning systems since the industry's early days — combining deep expertise with relentless efficiency gains.
Geothermal heat pumps — sometimes called GeoExchange, earth-coupled, or water-source heat pumps — have been in use since the late 1940s. They use the constant temperature of the earth as the exchange medium instead of fluctuating outside air.
Imagine a home or business where the temperature is always comfortable, yet the system is out of sight and requires minimal maintenance. Geothermal HVAC brings buildings into harmony with the earth beneath, using subterranean temperatures to heat in winter and cool in summer.
Coldflow works constantly to introduce higher-efficiency products. We know the name of the game as a pioneer in geothermal manufacturing.
We earn employee and customer respect by operating safely at every stage — from manufacturing floor to final install.
Businesses across the globe rely on Coldflow for systems that run day in, day out, year after year.
Our geothermal units consume 25-50% less electricity than conventional HVAC — savings that compound for decades.
Standard catalog or fully bespoke — every unit is built to spec and tested before it leaves the floor.
