Furnace Installation and Repair in Muskoka and Surrounding Areas

Keep yourself and your loved ones warm during the winters, with furnace servicing from Brennan's Inc. We offer furnace installation and repair in Muskoka and surrounding areas. Be it installation of a new furnace or repairing an existing one, our knowledgeable team can do it for you.

Furnaces generally have a lifespan of 10-15 years, but this can also depend on the frequency of use, quality of equipment, and how frequently the furnace is serviced. A regular maintenance of the furnace at regular intervals can help you save on your utility and repair bills. If you require a periodic servicing of your furnace, our team can assist.


There are a variety of furnace systems on the market that range in price and capabilities. The efficiency of new furnaces is measured by the annual fuel utilization efficiency (AFUE), a measure of seasonal performance.

Furnaces today operate between approximately 78% AFUE and 95% AFUE. Traditional "power combustion" furnaces operate between 80% AFUE and 82% AFUE. Furnaces operating above 90% AFUE are classified as high efficiency. High-efficiency furnaces are built to deal with condensation better than traditional systems, as they recapture some of the lost heat by condensing escaping water vapor. Factors we recommend considering when purchasing a new heating system are the following:

  • Cost

  • Comfort

  • Reliability

  • Efficiency

  • Quiet operation
