Winters in Elgin, Illinois, require the furnace to run for the majority of the year… The system combats temperatures well below zero on a regular basis, like any appliance, the heating system needs regular repair and cleaning to operate efficiently, effectively and reliably, when I first beginning up the furnace, I officially notice the smell of burning dust wafting from the vents.
This aroma reminds me to schedule repair from a local HVAC supplier.
The serviceman takes care of cleaning the several components, verifying safe operation and making any necessary adjustments; If he should find any minor troubles, these repairs are resolved before they graduate into much larger and more extravagant troubles. Last winter, I observed a different smell from the furnace many months after the proactive repair was completed. The air from the vents smelled musty and there was a significant amount of dust blowing around. I was worried about indoor air quality and the health of my family. I hoped that replacing the air filter would repair the problem. When I researched online, I learned that the aromas could be due to mold growth inside the heater, overheating or parts not operating properly. I decided to schedule repair right away. The serviceman checked out the furnace and found that the troubles were caused by the ductwork. There was a buildup of dust and other debris inside the pipes. Whenever the furnace started up, the allergens and aromas were getting spread to every room in the house, then fortunately, duct cleaning worked on it.
