It is unwise to ignore any strange smells from the furnace.
As long as the scent you perceive is different from what you usually would expect, then there is cause for alarm.
More often than not, these smells will indicate an underlying issue that may be dangerous or not. S such, assuming it could be a wrong move, especially if it eventually becomes detrimental. However, if you are knowledgeable about some of the smells, you can control your ability to handle the situation or panic. After all, all HVAC challenges have a solution. Some may require emergency intervention, while others may wait for a later fix. Please do not rush to call your HVAC technician when any of the following happens when it comes to odors. These are normal smells that have quick fixes. First, you should never panic whenever you perceive dust or first burning smells. This is an issue that comes up mostly when using your furnace after a long period of disuse. Fortunately, the burning smell often lifts after a few minutes since the dust accumulated burns out quickly. It should also not be so intense but rather a light burning odor that dissipates quickly. Oil odors should also be safe to work with since they signify a clogged oil filter. Once replaced, this issue will be sorted out fast enough. Sometimes, instead of the dust-burning smell, you are likely to perceive a musty smell when the furnace is switched on. This is a result of accumulated dampness over time. However, if you feel that the smells linger for longer periods than you would like, consider having an HVAC contractor check the issue out. This could improve air quality as well.
