Why Does My Heater Smell Like It’s Burning?

February 28, 2023 | Blog

A heater may smell burnt for a number of reasons. While some of these issues can be resolved quickly, others call for expert help. Recognizing what to do when you notice a burning smell from your heater will save you a great deal of trouble and expensive repairs.

Whether your home uses a furnace or heat pump, any heat source emitting a burning smell requires quick care to prevent further problems. If your heater generates a burning odor, be mindful of the following, compiled by our team at Heblon Heating & Air Conditioning:

Dirty Vents And Air Filters

Your heater’s filters may clog up and emit a burning odor if you don’t maintain them on a regular basis. Old ventilation systems can also encourage the growth of mold and mildew in your ducting, giving off a musty odor.

Burning scents brought on by build-up on older filters can be avoided by routinely replacing air filters. To get the most out of your heating system, replace the air filters every three months.

Check for mold and mildew in your furnace if you notice a musty smell. Then, change the filter after properly cleaning the heater. If the musty odor persists, the ductwork in your home may contain mold or mildew.

Dust On The Heating Unit

The most common source of a burning smell when you initially switch on your heater is dust accumulation on your furnace. It’s possible that the furnace isn’t used all year for homeowners outside a location with frequently changing seasons, like the Mid-Atlantic.

In the months it sits unused, dust builds up on your furnace. This dust starts to burn off when you switch it on for the first time, frequently giving the house a burning plastic smell. Fortunately, dust accumulation on your furnace typically isn’t a reason for alarm because the stench should go away once the dust burns off. Without touching it, look over your appliance to check whether any dust has accumulated.

Electrical Issues

If your heater is generating a burning electrical odor, you may have a significant electrical issue. The electrical wiring in your system may smell during use due to improper installation and/or general wear and tear over time.

If your wiring is faulty, it may lead to a fractured heat exchanger, an overheated blower motor or a number of other issues that you’d probably rather avoid. These are all major issues that should be handled right away, only by qualified HVAC specialists.

Once they start to overheat, many HVAC systems have a safety feature that will turn the unit off. But faulty wiring might make the heating system break down and keep heating up.

What Our Customers Are Saying

Highly Recommend Using Heblon

My AC wouldn’t turn on so I called Heblon . It was a Sunday and from calling the office to the engineer arriving took about 45 minutes. The engineer was professional and gave me excellent feedback on the issue. Repaired within 45 minutes and couldn’t ask for more. Highly recommend using Heblon, and will definitely be using them from now on.

Both technicians were respectful and courteous. They went above and beyond to explain issues with my unit that would require work in the future. They offered assistance with out a pushy sales pitch. Good overall experience.

Jerry is part of the family now. He is always professional, knowledgeable, and able to fix the problem. I really appreciate the great customer service I get from the time I call the office, the prompt response, the timely arrivals, the updates via text message, and the follow up after the job is complete. I wouldn’t trust anyone else but Heblon. My family is grateful for them.
