\"Furnaces<\/a>
\n<\/a>With autumn rolling by, there\u2019s no doubt that winter will creep up on us when we least expect it. Perhaps you enjoy winter \u2013 tobogganing, building a snowman with your kids, skiing and snowboarding \u2013 but we can all agree that nothing beats coming inside to a well heated home after some time in the snow. What if your furnace<\/a> stops working altogether? Before you panic and start putting on your snow pants & scarf and gathering wood for a fire in your living room, there is a bit of troubleshooting you can do.

It is highly recommended that you change your filter every 1-3 months, just to be on the safe side.<\/p>\n

3)\u00a0\u00a0\u00a0\u00a0\u00a0 Make sure there\u2019s no snow blocking the exhaust or intake vents outside. While the heat of the exhaust from the vent often melts the snow and ice in its immediate area, a buildup of snow around the venting can cause safety controls to shut down the unit.<\/p>\n

4)\u00a0\u00a0\u00a0\u00a0\u00a0 Often times, a lack of heating can be caused by an incorrect setting on your thermostat. Check your thermostat for the following things:<\/p>\n
