Is a Burning Smell Normal When I Turn on the Heat?

If you’ve turned on your heat for the first time this season and noticed a burning smell, you’re not alone. A lot of people experience this problem each year. In most cases, it’s nothing to worry about – but it’s still essential to find out what’s causing the smell. Keep reading to learn more about some common reasons why your heating system might be emitting a burning smell.


Burning Dust 

Dust can accumulate on the exterior and interior of your system, releasing an odor as soon as someone turns it back on! This isn’t necessarily something to worry about; most people experience this phenomenon only during the winter months (when they leave their thermostat set lower than usual). However, if this smell persistence continues past morning hours or after cleaning the air filters, then there might be another issue at hand, such as blocked vents.


Electrical Smell

Electrical smell? You may have something stuck in your heating and cooling system’s ductwork. If you notice an odor that smells like burning plastic or electrical parts, it could be because of a foreign object. If this happens, figure out what needs fixing before anything else gets worse!


Smoke Smell

Why does my furnace smell like smoke?

A blockage in the chimney could cause a dangerous flue fire, so it’s important to check for this problem before continuing with daily activities. If you notice any unusual noises or smells coming from your heat source, then contact an HVAC technician as soon as possible – there may be serious issues.
