I think the last time I had to have an HVAC company to my house was a good five years ago. I remember it, because it was winter, I had an awful flu, and I was home sick from work. I thought to myself ‘well why not take advantage of this’ and had the heating and cooling system in my home tuned up and my ducts cleaned. I remember I had been really excited about the ductwork being cleaned. I was convinced some of my sickness was actually allergies that I was getting thanks to ducting that was clogged with dust, dirt, and hair. I was only half right, it turned out. After the HVAC ducts were cleaned, and the repairman left, I was just as sick as I had been that morning. On the other hand, a few weeks later, when I was recovered from my bout of flu sickness, I felt that I could breathe a lot easier at home than before. Over the years the ducts have become dirtier until the point they’re at now, which is why I’m having an HVAC repairman come out to the house in a few days to clean 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 right away! I’m a little ashamed of how excited I actually am about having the HVAC ducts in my house cleaned… I am subsequently considering taking up a hobby.
