We understand the concept of boilers can be confusing. Simply put, gas- and oil-fired boilers circulate steam or warm water through a series of pipes to heat your Ann Arbor home more efficiently. Lennox® is well-known for quality and reliability, and much like the company’s furnaces, their boilers are designed for maximum efficiency and reliability.


Many people still use boilers to heat their homes, and while they work very differently from furnaces or heating systems that are ducted and circulate warm air, boilers can be highly efficient, providing the extra warmth you need during the cold winter months without sending utility costs through the roof.


Whether your boiler is in need of repair or you need a gas- or oil-fired boiler installed, our NATE certified technicians are experienced, highly trained, and dedicated to your satisfaction.


Lennox® is the name to trust in residential boilers. Ann Arbor and Dexter residents will enjoy the ability to keep utility costs under control while minimizing heat loss and improving comfort. With efficiency ratings of as much as 95% AFUE homeowners can enjoy significant savings whether with the equipment mentioned above, the COWB2, GWB9, or another model. Our professionals can help determine which unit is right for your needs.
