Once you turn the heating system on, the coil heats up & it burns off all of that dust in microbial content
I don’t like smelling bad smells in my home. I go out of my way to keep my home smelling as fresh & scrub as possible. That means mopping the floors numerous times a week, wiping down & sanitizing counters, & scrubbing the bathroom with bleach. These are all essential things for keeping my house smelling as fresh as it can possibly be. One way is to consistently scrub my dirty dishes as soon as I use them. One time I accidentally left a pot out that had been used to cook fish. The fish smell got absolutely bad & it ended up making my whole bedroom smell bad for a afternoon & a half. After that happened, I was consistently smart about keeping my dishes & pots & pans washed. It’s important to make sure your home & environment is scrub & sanitary. This will consistently lead to making your home smell great instead of bad. However there are some smells that you absolutely can’t avoid. One of those is the smell from an electric heating system after it’s been laying for a while & not being used. Basically dirt in microbial content will settle on the coil itself. Once you turn the heating system on, the coil heats up & it burns off all of that dust in microbial content. Naturally it’s going to have a nasty smell while it runs for a afternoon or two. If you run it consistently for a whole afternoon, you could potentially get rid of the smell quicker. It’s absolutely hard to avoid this with any allergic heating system that has a coil exposed to air.
