What’s That Burning Smell?

Published On November 9, 2018


Temperatures are lowering in Texas, meaning it could be the first time you’re turning on your heater this year. Turning on a heater after a couple of months of inactivity could expel a nasty, musty, and even burning smell. Not only is the scent unpleasant but it could be quite irritating and uncomfortable to those with allergies and other health problems.

The Source

Over time, it’s normal for dirt, dust, and debris to accumulate on your vents, registers, and equipment. When your system is turned on after being dormant for some time, these materials burn up and cause that burning smell. Although that initial burning smell is common, it doesn’t mean it should be ignored.

Here’s what you could be doing:

  • Replacing your air filter – Accumulated dirt and debris on your air filter may cause a burning smell once heat passes through. Simply replacing your clogged filter with a fresh one can prevent the smell from occurring.
  • Checking your system for foreign items nearby – Inspect your heater for external items such as fabrics or plastics. Make sure your system is clear of any external objects that have the potential of being burned or damaged by your heater. If any plastic or rubber is burning due to your heater, make sure to turn off your heater immediately and remove the object. These fumes can be hazardous and could even indicate a more serious problem such as an electrical failure. If you are unable to locate and remove the source, make sure you call us today so we can properly resolve your issue and get your system up and running again!
