Smell Something Bad from the Furnace?

Burning Furnace Smell

A burnt smell coming from your furnace can indicate a serious problem. The problem could be due to malfunctioning electrical components or a dirty filter. When you notice a strange odour, you should inspect the area. Contact the fire department if your furnace is on fire. If you cannot find the source of the problem, you should contact an HVAC engineer. Cleaning the furnace may resolve the issue, but the unit may need to be replaced if the strange odour persists.

Dirt Inside the Furnace

Dust inside the furnace can cause a foul odour. After several months of being idle, dirt will accumulate inside the unit. When the dirt burns, the blower circulates the foul smell throughout your London home. You can open a window to let in fresh air, but the furnace will still need to be inspected by an HVAC engineer. Dirt inside the ducts can also cause a lingering burnt odour.

Dirt Inside the Filter

A clogged filter can cause a burnt odour. An oily smell usually indicates a problem with the filter. The filter absorbs pollutants, and fresh air cannot circulate throughout your London home when the filter is clogged. A dirty filter is also a fire hazard. An HVAC engineer can inspect the filter and electrical components inside your furnace.

Broken Electrical Components

If the furnace will not blow warm air, there could be a problem with the electrical components. The furnace can overheat if any of the electrical parts malfunction. If the furnace blows cold air, you should contact an HVAC engineer immediately. ‘

Most electrical problems are due to the motor malfunctioning. The motor needs to be lubricated on a regular basis. If the motor is still overheating after being oiled, an HVAC engineer may recommend replacing the furnace.

When you notice a strange odour coming from your furnace, turn the unit off immediately. If the smell does not dissipate after turning off the furnace, you should contact the fire department immediately. Prolonging repairs can worsen the problem. An HVAC engineer can find the source of the odour and promptly resolve the issue.
