After finding a lot of dust in my home, I knew that the ductwork had to have something to do with it. I called the HVAC company and they sent a technician to my house. He cleaned the furnace and the air conditioner, changed all of the air filter, and then he checked the ductwork. Within a couple hours, he had fixed the cracks and pinholes in my ductwork and told me that I should not have any more problems with excess dust. I was no longer worried about the excess dust, I was worried about all of the other contaminants that may have entered my home, while the ductwork was broken. He said it was a possibility, but if I was really worried, I could have an air purification system installed into my HVAC system. I asked a lot of questions about HEPA filters and how the air purification system worked. He told that through a system of UV lights and air filters, even the smallest of germs and bacteria were trapped before getting into the house. The UV light would attract and kill any mold, mildew, or other spores, while they circulated through the ventilation system. He took time to explain how the air purification worked and I was anxious to get it installed. I have to admit that I have been feeling much better since my allergies are under control. I don’t feel so miserable all of the time, but I told my kids not to think I would be less miserable. I am still an old woman who is set in her ways. If they don’t want honesty they shouldn’t ask for it.
