Why Does Your Furnace Smell When You Turn It On? 11/01/2016 The temperatures are decreasing here in Florissant and that means soon we’ll be relying on the comfort of our furnaces. This is typically the time we have several furnace repair calls from our customers anxious about a strange smell evading from their furnace. If it’s been a few months since you’ve turned on your furnace and you smell something strange, stay calm. There’s probably nothing to worry about and there are a number of 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, dust may have accumulated inside of your furnace. Starting up your furnace for the first time will burn that off, leaving a smell. This smell will spread through your home throughout your duct work. This usually isn’t a serious condition and the scent will not last long. But, if the smell doesn’t go away after a brief time, you’ll have to call in an expert to assess the issue. Another probable cause of interesting 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 B & B Heating & Cooling in Florissant are ready to check things out and set your mind and nose at ease.
