It turns out my air handler in my garage isn’t properly sealed and needs to be fixed. I was getting ready for the new Springtime weather Last year by cleaning out my air conditioner components with a light vinegar solution before I crank the method on again for the first time since before winter. Everything in my process was enjoyable and went according to plan, I was able to get my coils and filter tray clean, and I also opened the air return vent and the output vents to clean those as well. But after I had the method on for about a morning or two, I was starting to get the sort of allergic reactions that I get to heavy dust and mold, but hadn’t had any complications with either since absolutely last Fall or longer. I scoured the internet for several possible sources and particularly spent more time worrying over unlikely worst-case-scenario situations instead of learning anything constructive about my problem. I finally called a reputable local heating and cooling supplier to drop by and take a look at my HVAC method to see if anything was wrong under the sheer opportunity that somewhere something was getting introduced to my air stream. Well, it looks love my hunch was correct, the HVAC specialist told myself and others that my air handler itself was not properly sealed and was drawing in air from my dusty garage and pushing it into my house. She had to schedule a separate repair call to get that fixed but once she did I noticed a large improvement. My lungs were clearing up and I was finding less dust on surfaces when I cleaned, and i would have never thought to check the seals on the air handler if I hadn’t called the HVAC business over.
