I honestly don’t take the best care of my Heating as well as A/C unit, I’ll admit it; My heating and cooling unit is kept in my garage, and since I rarely visit there, they end up collecting a crap ton of dust, but i know this wouldn’t be too terrible except when I go to do basic repairs love decreasing the a/c filter, and I literally get covered in dust, but you think it’s terrible when I do Heating as well as A/C contractor and starts coughing undoubtedly loudly when he’s around my Heating as well as A/C system. It’s kind of embarrassing, so to prevent stuff love this from happening, for both me and my guest’s sake, I have decided to start giving it a weekly clean. I already deliver my beach house a weekly clean involving cleaning the windows, the counters, the furniture and the floor, so adding the Heating as well as A/C component won’t hurt, however sure enough, as soon as I took a damp paper towel over and cleaned both my a/c and oil furnace, and by the time I was done the bottom of the paper towel was literally black. I was disgusted at how much filth has built up on my gas furnace and AC overtime, and this only cemented my decision to clean my Heating as well as A/C component every week! A few weeks later and I have been cleaning now every month and now there is undoubtedly little dust, and even guests have commented that my beach house and the air quality feels a lot better, and now I might just need to up the amount of Heating as well as A/C service I have and I will be fantastic to go.
