Troubleshooting Your Furnace

If you wake up one morning to a freezing cold house despite the heat being turned up, you’ve got a problem. While most of the time furnaces are a solid and reliable source of heat, they do sometimes break down. When it’s freezing both inside and out and you need a quick fix to your furnace issues, there are a few troubleshooting tricks in order to get it pumping heat again. If these don’t work, call on Fox Valley plumbing and furnace installation pros at J.L. Wagner Plumbing and Piping.

Check the Thermostat – This might seem obvious, but it’s still necessary to double check the thermostat to ensure it is set correctly.

Filter Trouble – If you’ve missed your regular air filter replacement then this may be the issue. Filter-related failures are one of the most common furnace problems. Check your filter for obvious signs of dirt. Also, listen for a whistle.  If the furnace can’t get enough air through the filter, it pulls air through any opening it can. A whistling sound is an indication of a problem.

Circuit Issues – If the thermostat is set, you’ve replaced the filter and your furnace still isn’t running, check the circuit breaker. If it’s in the “off” position, or in-between on and off, reset it. If it’s in the “on” position but isn’t working, flip the switch to try resetting it.

Depending on the type of system you have – forced-air heating system, a furnace, or a heat pump – there are a number of other issues that can be the cause of your heat troubles. If none of these quick fixes help, call a technician who can investigate the problem and find a solution quickly.
