Why Does My Heater Smell Like It’s Burning?

Heater Smells Like Burning

In Florida, we get to enjoy warm weather all year round. Many Floridians are lucky enough to be turning on their heater for the first time this year. However, if a burning rubber or burning plastic smell is coming out of your heater, you may be left feeling anything but lucky. Learn what these burning smells could mean and the best way to deal with them.

Smells Like: Burning Dust

After leaving your heat pump, furnace, electric heater, or any other heating system turned off all summer, dust and other debris can collect on the heating elements. So when you switch it on, all this dust gets burned off. This burning smell then gets pumped into your home along with the warm air, and that’s when you begin noticing the odd smell. It is normal for this to happen, especially at the beginning of the heating season. The smell usually lasts no more than 30 minutes, if it lasts longer this could be a sign of a more serious problem.

Clogged Filters

When your heater’s motor is overworked, it also produces a burning smell. One of the most common causes of an overworked motor is a clogged filter. If you do not change your air filter, the burning smell will only increase and the motor may actually give out. Replacing your furnace filters before turning on your heating for the first time each season could save you a whole lot of trouble.

Damaged Furnace

Something other than dust may be burning! Your systems motor can also overheat due to age, wear, and lack of AC maintenance. It may simply be that the motor requires oil but there is a chance that it could also be a very serious problem. If the smell does not go away after you add oil, you should turn off your system and call in a professional HVAC technician to evaluate the problem for you.

Closed Vents

If too many of the vents in your home are closed or blocked off, then it could be a reason for that burning smell. Your HVAC system tries to push out all the warm air to your home but when the vents are shut off, that air becomes trapped, causing a variety of issues for your system. Unlike cool air, you can actually smell when too much hot air is being trapped as it has a burning odor.
