I think the last time I had to have an Heating and A/C company to my home was a great multiple years ago. I remember it, because it was winter, I had an awful flu, and I was lake house sick from work. I thought to myself ‘well why not take advantage of this’ and had the heating and cooling plan in my lake house tuned up and my ducts cleaned. I remember I had been really gleeful about the HVAC duct being cleaned. I was convinced some of my sickness was really pollen irritations that I was getting thanks to ducting that was jammed with dust, dirt, and hair. I was only half right, it turned out. After the Heating and A/C ducts were cleaned, and the repairman left, I was just as sick as I had been that afternoon. On the other hand, a few weeks later, when I was reclaimed from my bout of flu sickness, I felt that I could breathe a lot easier at lake house than before. Over the years the ducts have become dirtier until the point they’re at now, which is why I’m having an Heating and A/C repairman come out to the home in a few mornings to scrub the ducts again for me. I’m glad that I am not sick this time around! I wonder if I’ll be able to notice a difference in the quality of the air immediately! I’m a little ashamed of how gleeful I really am about having the Heating and A/C ducts in my home cleaned… I am subsequently considering taking up a interest.
