Why Does Your Furnace Smell When You Turn It On? 11/01/2016 The temperatures are dropping here in Carlsbad and that means soon we’ll be relying on the comfort of our furnaces. This is usually the time we have several furnace repair calls from our clients concerned about a unusual smell coming from their furnace. If it’s been a little while since you’ve run your furnace and you smell something bizarre, stay calm. There’s typically nothing to worry about and there are a few reasons your furnace may smell strange. Last winter was maybe the last time you’ve had to operate your furnace. For most of the year, dirt may have gathered 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 generally isn’t a dangerous condition and the smell will not last long. However, if the smell doesn’t go away quickly, you’ll need to call in an expert to assess your system. Another possible cause of interesting smells coming from your furnace is a clogged 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 Banister's Heating & Air Conditioning Services in Carlsbad are ready to check things out and set your mind and nose at ease.
