Slide 1

Specializing in Geothermal Systems

Ground temperatures are a constant 55 degrees all year. Geothermal works because the ground beneath our feet is warmer then the outside air in the winter and cooler in the summer. Inserting a series of small pipes into the ground allows heat to be transferred to and from your home. In this process heat is not created, it is transported therefore no fuel is burned.

Conveniently located!

Our service area covers all of the Metro St. Louis area, including the City of St. Louis and surrounding counties. In addition to the City and County of St. Louis, our central location allows us to service all of the Metro Area, from Southern Illinois to Warrenton, MO and beyond!

Services Offered

Our extensive knowledge and experience goes well beyond the service and installation of furnace and air conditioning systems. We are experts in working with sheet metal, for instance. We also service water heaters, including solar water heaters. Our expertise in heating extends to radiant floor heat as well.

Radiant Floor Heating

Floor heating saves energy up to 40%. All the energy is converted to radiant heat directly below the surface of your floor creating floor-to-body warmth. No energy is expended blowing air or pumping water and no heat is lost in the ductwork.

Solar Water Heaters

Solar water heaters, also called solar domestic hot water systems, can be a cost-effective way to generate hot water for your home. They can be used in any climate, and the fuel they use -- sunshine -- is free.

Heat Pumps

A heat pump is a device that uses a small amount of energy to move heat from one location to another. Heat pumps are typically used to pull heat out of the air or ground to heat a home or office building, but they can be reversed to cool a building.
