Why Does My Heater Smell Like It's Burning?

December 19, 2023 | Blog

Hazlehurst Heating Company

When winter arrives – and the temperatures drop in Hazlehurst, MS, many homeowners fire up their furnaces to stay warm. But have you ever turned on your heater and been greeted by an alarming burning aroma? You’re not alone!

At Channell Heating & Cooling, we often receive calls from concerned homeowners about this very issue. In this blog, we’ll dive into the reasons behind that burnt odor from your heater and whether it’s a cause for concern.

Understanding A Burning Heater Smell

When you first turn on your unit, especially after it’s been dormant for a while, it’s not uncommon to notice a burning smell. But what’s causing it? Our team is here to provide you with the possible causes.

Dust Accumulation

One of the most common reasons for a burning smell from a heater is the accumulation of dust and debris. During warmer times of the year when your unit is not in use, dust can settle on the heating elements or furnace burners.

When you finally turn on the heater, this dust gets burned off, producing a distinct odor. This is generally harmless and should dissipate after a short while.

Dirty Furnace Filter

A dirty furnace filter can restrict airflow, causing the unit to overheat. When this happens, you might notice a burning smell. Regularly checking and replacing your furnace filter can prevent this issue and improve the efficiency of your system.

When Should You Call For Heater Services?

While the occasional burnt smell from your unit can be harmless, there are times when it can indicate a more serious issue.

Electrical Issues

An odor that resembles melting plastic or electrical burning is a cause for concern. It could indicate a problem with the heater’s wiring or a malfunctioning component.

If you notice this type of aroma, it’s important to turn off your system and call a Hazlehurst heating company like Channell Heating & Cooling for a professional inspection.

Blocked Vents

Blocked or restricted vents can cause your unit to overheat, producing this aroma. Ensure that all vents in your home are free from obstructions like furniture, curtains or toys. Regularly cleaning your vents can also help prevent dust accumulation, which can contribute to the burning odor.

Preventing The Burning Smell

To ensure your furnace operates efficiently and safely, regular maintenance is crucial. Our experienced technicians are your trusted professionals to combat HVAC odors.

Routine HVAC Repair And Maintenance

Scheduling routine HVAC repair and maintenance with a trusted Hazlehurst heating company can help identify and address minor issues before they become severe. Our technicians can clean and inspect your system, ensuring it’s in top condition for the colder season.

Regularly Replace Filters

As mentioned earlier, a dirty furnace filter can be the cause of a burnt smell. Ensure you change the filter as recommended by the manufacturer or your HVAC professional.

Don’t Suffer Through Heater Odors

Turning on your furnace and smelling a burning odor can be alarming. In many cases, the aroma is harmless and temporary. But it’s essential to be aware of when it might indicate a more serious issue.

Regular maintenance and prompt HVAC repair can help ensure your heating system runs safely and efficiently.

Very Thankful for Their Service

They installed our old system and took care if all maintenance since 1995. This year it finally needed replacing. They installed a quality Trane system and it’s been running efficiently ever since. Very thankful for their service.
