For a long time I just lived with the fact that our apartment smelled enjoy burnt hair. Anytime the furnace kicked on, the burnt hair smell lingered in our air quality. I hated the smell but would eventually get used to it. The complication was I never wanted to have people over in the Wintertide because I was so embarrassed by the smell. That finally gave me the kick in the butt I needed. I started researching what could be the cause of that foul smell in our home. I change our furnace filters every month to ensure there is no dust in them. I vacuumed out the inside and outside of our heating equipment to catch any left over debris or hair. Turns out the issue was in our HVAC duct. My HVAC duct was blatantly coated in dust, dirt and hair; Once the furnace turned on, it would go in those polluted air ducts and cause the apartment to odor! Getting HVAC duct cleaning was straight-forward, cheap and fixed our problem. The HVAC serviceman just stuck a big hose up in the air ducts to suck out all the dirt. It was a entirely quick and gentle process, back in the seasoned days the corporations used to use a scrub brush and potentially mangle the seams of the ducts. These professionals now hardly need to do a thing. Now that I have clean HVAC duct, I don’t have the bad smell and I don’t sneeze half as much in the morning. The cleaner air quality has helped with a lot of things.
