Why Does Your Furnace Smell When You Turn It On? 11/01/2016 The temperatures are dropping here in Saint Louis and that means soon we’ll be relying on the comfort of our furnaces. This is usually the time we receive a number of furnace repair calls from our customers concerned about a unusual smell escaping from their furnace. If it’s been awhile since you’ve turned on your furnace and you smell something strange, stay calm. There’s probably 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 operate your furnace. For most of the year, dirt may have accumulated inside of your furnace. Running your furnace for the first time will burn that off, creating a smell. This smell will move through your home throughout your duct work. This typically isn’t a dangerous situation and the odor will not last long. But, if the smell doesn’t go away in a short while, you’ll want to call in a professional to assess the issue. Another realistic cause of strange smells coming from your furnace is a congested 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 experts at Morgner Incorporated Air Conditioning & Heating in Saint Louis are ready to check things out and set your mind and nose at ease.
