Why Does Your Furnace Smell When You Turn It On? 11/01/2016 The temperatures are decreasing here in Crystal Lake and that means soon we’ll be relying on the comfort of our furnaces. This is traditionally the time we receive several furnace repair calls from our clients worried about a strange smell coming from their furnace. If it’s been a little while since you’ve used your furnace and you smell something weird, stay calm. There’s typically nothing to worry about and there are several reasons your furnace may smell strange. Last winter was most likely the last time you’ve had to use your furnace. During the year, debris may have built up inside of your furnace. Running your furnace for the first time will burn that off, producing a smell. This smell will spread through your home throughout your duct work. This typically isn’t a serious circumstance and the smell will not last long. But, if the smell doesn’t go away in a short while, you’ll want to call in a technician to take a look at things. Another probable cause of interesting smells coming from your furnace is a blocked air filter. A clogged filter will cause your blower motor to run harder which could cause the motor and/or your furnace to overheat. You’re better safe than sorry and if there are any odors coming from your furnace the team at Jett's Heating & Air Inc. in Crystal Lake are ready to check things out and set your mind and nose at ease.
