Calgary winters are long and cold, and your gas furnace works hard 24/7 to keep you warm. The typical lifespan of a gas furnace ranges from 10 to 20 years, but how long yours will last depends on several factors, including whether it was sized and installed properly and how well-maintained it is.
Over time, belts and gas and electrical connections become loose, dust builds up on essential components and fuel efficiency decreases. Annual preventive maintenance addresses this typical wear and tear to increase furnace efficiency and prevent problems later on, and it's a major factor in the longevity of your furnace. A properly maintained furnace should last at least 20 years, possibly as many as 30. A neglected system, on the other hand, can fail before the 10-year mark--especially in Canada, where your system is operating almost constantly for months on end.
