Why Does Your Furnace Smell When You Turn It On? 11/01/2016 The temperatures are dropping here in Phoenix and that means soon we’ll be relying on the comfort of our furnaces. This is typically the time we receive several furnace repair calls from our clients anxious about a strange smell evading from their furnace. If it’s been a little while since you’ve turned on your furnace and you smell something strange, stay calm. There’s typically nothing to worry about and there are a few reasons your furnace could smell strange. Last winter was most likely the last time you’ve had to use your furnace. Throughout the year, dust 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 travel through your home throughout your duct work. This generally isn’t a harmful condition and the smell will not last long. Although, if the smell doesn’t go away in a short while, you’ll want to call in a professional to assess your system. 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 Dial One Mears Air Conditioning & Heating Inc in Phoenix are ready to check things out and set your mind and nose at ease.
