Why Does Your Furnace Smell When You Turn It On? 11/01/2016 The temperatures are dropping here in Denver and that means soon we’ll be relying on the comfort of our furnaces. This is traditionally the time we receive several furnace repair calls from our customers anxious about a weird smell coming from their furnace. If it’s been awhile since you’ve used your furnace and you smell something strange, stay calm. There’s typically nothing to worry about and there are a few reasons your furnace might smell strange. Last winter was probably the last time you’ve had to run your furnace. During the year, debris may have built up inside of your furnace. Running 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 generally isn’t a serious situation and the odor will not last long. However, if the smell doesn’t go away quickly, you’ll want to call in an expert to take a look at the issue. Another realistic cause of strange 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 Northglenn Heating & Air Conditioning, Inc. in Denver are ready to check things out and set your mind and nose at ease.
