Furnace Repair in Mundelein, IL

We all know how brutal the winters in Illinois can be, and the last thing you want is a furnace breakdown while Mother Nature is doing her worst outside. Sooner or later, however, that’s probably going to happen, no matter how well you’ve maintained your furnace. When a breakdown occurs, Gleason Heating and Air Conditioning is the company to call for expert repair services in Mundelein.

When your furnace goes out on you, there are some possible DIY fixes you might try before calling for help. These include the following:

• Old, dirty filter – A dirty, clogged filter can cause your furnace to struggle to keep your house warm. Eventually, if it overheats, the furnace will probably shut down as a safety precaution. So, try replacing the old filter.
• Thermostat setting – Make sure your thermostat is set on “Heat.” It’s possible someone may have accidentally turned the heat function off.
• Circuit breaker – Find your electrical panel and see if the heater’s circuit has been tripped. If it has, reset it to the “On” position and give the furnace some time to recycle and restart.
• On/Off switch on the furnace – Your furnace may have a switch that looks like an ordinary light switch, and it might have been moved accidentally to the “Off” position. If so, move it to the “On” position.

If these DIY suggestions don’t get your furnace running, it’s time to call in the furnace repair professionals from Gleason.
