Due to the long and cold winters in Fort McMurray, furnaces last less than industry averages. If your furnace is five years or older, depending on the unit, you may want to have it inspected, and possibly replaced. Like cell phones and personal computers, the technology used in central heating systems and furnaces is becoming more sophisticated and intelligent. The money you save over a year installing a new state of the art central heating system may pay for the unit itself. You will also have peace of mind that your new heating system is protected by warranty and you will not be left out in the cold.
