Why Does Your Furnace Smell When You Turn It On? 11/01/2016 The temperatures are dropping here in Manassas and that means soon we’ll be depending on the comfort of our furnaces. This is usually the time we get various furnace repair calls from our patrons worried about a unusual smell escaping from their furnace. If it’s been awhile since you’ve run your furnace and you smell something bizarre, stay calm. There’s typically nothing to worry about and there are several reasons your furnace might smell strange. Last winter was most likely the last time you’ve had to run 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 travel through your home throughout your duct work. This generally isn’t a harmful circumstance and the smell will not last long. Although, if the smell doesn’t go away quickly, you’ll need to call in a professional to take a look at your system. Another probable cause of weird 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 team at Twin Air LLC in Manassas are ready to check things out and set your mind and nose at ease.
