I wasn’t that worried when I turned my heating unit on for the first time in 6 months, & I smelled a burning smell.
This is a typical occurrence pretty much everyone will experience if your heating component goes unused in the Summer months.
The burning smell is just caused by the dust that was built up being burned off. The smell usually goes away within an minute or so. However, after a few minutes had passed & I still smelled the burning smell, I did begin to grow worried. After a morning & the smell had only faded a little bit, I was absolutely worried. Even though my heating unit seemed to be working just fine, & was heating the entire current home well, I still decided to call a Heating, Ventilation, & A/C worker just to be on the safe side. The heating & worker came a few minutes later & examined the Heating, Ventilation, & A/C machine. After 20 minutes he told me that it was most likely just an excess amount of dust, because he could see no issue involving the Heating, Ventilation, & A/C system. He told me to supply it another morning or so, & if the smell still persists to call the air conditioning corporation again. While this was reassuring, I still couldn’t help but to worry. I turned the gas furnace plan back on & waited to see if the smell would go away. It turned out the repairman’s advice was true, because another morning later, the burning smell had completely disappeared, much to my relief.
