Electric

Furnaces

Electric Furnaces are perfect for single-family homes and townhomes in Sarnia without access to a natural gas line. ENERGY STAR-certified electric furnaces are trusted systems that offer consistent heating and energy savings.

High-Efficiency

Gas Furnaces

High-efficiency gas furnaces are designed with durability and reliability in mind. Perfect for homes in High Park, Oakwood Corners, Wees Beach, and other homes in Sarnia with a natural gas hookup, these appliances will keep you and your loved ones warm throughout the wintertime, no matter how cold outdoor temperatures become.

Hybrid-Systems

Furnace + Heat Pump

Hybrid systems feature a powerful gas furnace and an energy-efficient heat pump. During the winter months when temperatures in the area drop well below freezing, your gas furnace will kick on to deliver consistent, powerful warmth throughout your interior. Then, when temperatures become milder, the system will automatically switch to your heat pump. By doing so, you can maintain energy-efficiency levels all winter long.

Hot Water

Boilers

For heritage homes located on Front Street, Downtown, and London Road that rely on radiant heating, the licensed HVAC technicians we've partnered with in the community are also able to deliver high-quality repair, maintenance, and installation services for boilers.
