With temperatures plummeting, a broken or malfunctioning furnace changes from an inconvenience to a life-threatening issue. HVAC companies will notice an increase of furnace repair calls, especially during dangerous winter conditions. In order to avoid an emergency situation, Midwest Heating & Cooling has three simple solutions:
When your furnace is running continuously, like it will in extremely cold temperatures, your furnace filter is going to get clogged twice as fast as it normally would. We always recommend checking your filter more frequently in the cold, and changing it as needed. If you’re unsure if your filter needs to be changed, you can shine a flashlight at it. If light can’t get through, you need a new one.
More often than not, programming the thermostat to adjust during the day will save you energy (and money), but when the wind chill is in the negative it can actually be harmful to your furnace. Furnaces are designed to keep up with a certain temperature; when it reaches below negative 20 degrees, you’re actually better off locking the temperature in place. Otherwise, the furnace will run continuously and increase your overall cost.
One of the biggest issues people will experience during a storm is with the furnace exhaust. If anything blocks the vent pipes, your furnace will automatically shut-off as a safety mechanism. When you’re shoveling your sidewalk or snow blowing your driveway, be very careful to keep away from your vent pipes to avoid blocking the exhaust, resulting in an emergency furnace call.
