What To Do About a Chemical Smell Coming From Your Air ...

Experiencing a dusty smell coming straight from your furnace is normal, especially if you haven’t run the system after quite some time. Dirt and dust can be accumulated in your furnace during the warmer part of the year when it’s dormant.

Therefore, this dust gets heated up as soon as you turn the furnace up. If the furnace keeps producing the smell a few hours after kicking start, you can turn your system off and try changing your filters.

Burning Oil Smell 

You cannot experience an oil-burning smell unless you’re using an oil furnace to heat your home. It can result from items falling next to your oil furnace’s pilot, thus catching a fire. It is most likely to happen if the furnace stays in the basement.

Ensure that you keep away dirt and debris to prevent such unnecessary fires. The smell might also be produced as a resulting issue from your oil and burner. The smell of oil can also be a sign of a blocked furnace oil filter. Always remember that you should replace the air filter at least once every two to three months, depending on your home. Check to see if the furnace filter is what’s causing the smell.

If your burner tends to miss some oil during the combustion process, it might create an oil fog that can start a fire and even produce smoke. Burning oil odour can also be brought about by spilling some oil when refilling the fuel tank, thus leaving the smell behind for a couple of days.

Plastic, Rubber, or Metal Smells
