Why Does Your Furnace Smell When You Turn It On? 11/01/2016 The temperatures are falling here in Marshalltown and that means soon we’ll be depending on the comfort of our furnaces. This is traditionally the time we have various furnace repair calls from our clients concerned about a unusual smell evading 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 most likely nothing to worry about and there are a few reasons your furnace might smell strange. Last winter was most likely the last time you’ve had to operate your furnace. During the year, dirt may have built up inside of your furnace. Running your furnace for the first time will burn that off, creating a smell. This smell will spread through your home throughout your duct work. This generally isn’t a harmful circumstance and the odor will not last long. Although, if the smell doesn’t go away in a short while, you’ll have 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 professionals at B & G HVAC in Marshalltown are ready to check things out and set your mind and nose at ease.
