Geothermal Installation And Repair

Geothermal systems use the earth's constant underground temperature to heat and cool your property with remarkable efficiency. These systems can reduce heating and cooling costs by up to 70 percent while providing decades of reliable service. We handle complete geothermal installations, from ground loop design to indoor equipment setup, and we're equipped to repair existing geothermal systems when problems arise. Our experience with both commercial and residential geothermal applications means your system will be properly sized and installed for the best performance.

Heat Pump Installation And Repair

Heat pumps offer an efficient alternative to traditional furnaces and air conditioners by transferring heat rather than generating it. Modern heat pump technology works well even in cold climates, providing year-round comfort with a single system. We install air-source and ground-source heat pumps for new construction and retrofit applications. When your existing heat pump needs attention, our technicians diagnose and repair issues quickly, with 24-hour emergency service available when you need help right away.

HVAC Zoning

Different areas of your home or building often have different heating and cooling needs, but a single thermostat can't address these variations. HVAC zoning systems use motorized dampers and multiple thermostats to control temperatures independently in different areas. This approach gets rid of hot and cold spots while reducing energy waste in unoccupied spaces. We'll design a zoning strategy that matches how you actually use your space, giving everyone control over their comfort without hurting efficiency.

Mini-Split Installation And Repair

Ductless mini-split systems provide efficient heating and cooling without the need for extensive ductwork. These versatile units work well for room additions, converted garages, older homes without ducts, and spaces where traditional HVAC installation isn't practical. Each indoor unit operates on its own, giving you precise temperature control in specific areas. We install single-zone and multi-zone mini-split systems, and we repair all major brands when they're not performing correctly.
