Geothermal Systems

Geothermal systems harness Earth's stable temperature for energy-efficient heating and cooling. Underground pipes circulate water-antifreeze mixtures to transfer heat, reducing energy bills by up to 70%. These eco-friendly systems qualify for tax credits and last 20+ years with minimal maintenance.

Radiant Heat

Radiant heat systems deliver consistent warmth through hydronic tubing installed in floors. This solution eliminates cold spots, improves air quality, and integrates with snow-melt systems for driveways. Propane-powered options provide reliable heating for off-grid properties.

Central Air

Our central air conditioning systems provide whole-home cooling with zoned temperature control. Ductless mini-split options offer flexible installation for homes without existing ductwork. All systems prioritize energy efficiency and quiet operation for maximum comfort.

Heat Pumps

Heat pumps provide year-round comfort by transferring heat between indoor and outdoor environments. Our models operate efficiently in moderate climates, with supplemental heating options for extreme cold. Systems include smart thermostats for optimized energy use.

Boilers

Modern boilers deliver reliable warmth through radiant or forced-hot-water systems. Our ENERGY STAR-certified models achieve 90-98% efficiency, significantly reducing fuel consumption. Upgrades include smart controls and low-emission combustion technologies for improved performance.

Excellent installation of Air Conditioning and correction and completion of a major heating system at our lodge hall. Great people to work with locally owned and real professional.

Very professional and easy to work with. We had issues relating to coordination with a electrician for final hook-up that was addressed professionally and to our satisfaction with little stress. Would be a good idea for them to either hire an electrician on staff to handle hookups. Were thinking a second system at some point in the future and would happily work with them again.

One of the finest professionals you will ever retain. Installed a heat pump and boiler in a distressed property in the middle of winter like clockwork. Then 2 months later after the basement flooded, Tony had it operational that Friday evening! Jeff and the team are the best.

5 star experience with Jeff and his entire team. We had his team over for an estimate a year ago and we had to put the job on hold. Once we wanted to pick back up Jeff responded quickly and got the job on the calendar. The install crew was excellent. On time, efficient, and great quality with the install. Can't recommend this company enough.

My wife and I had to take the time to let you know how amazing Jeff and Les are. We could never have foreseen how superb they are when we recently purchased our furnace and hot water heater from them. (The installation and all aspects went smoothly). Yesterday, our new furnace was significantly damaged because of a power surge through the electrical line. The furnace was repaired in a day to ensure that we were warm in February. Jeff replies to calls right away and takes care of your needs immediately. Les is so professional and he truly cares about you, making sure to do everything possible to
