After a lot of repairs and renovations this year, and several years of neglect, I wanted to clean our ducts, and upgrade our furnace. I chose CAPPS because of the good ratings on HomeStars. I talked to Paul about both things on the phone and he suggested I let him start with the cleaning to check out the house and the system, and then he would advise on adding a HEPA filter and a VOC filter. I found his advice similar to information I had found independently, he added the idea of UV lighting for germ control, and his pricing was competitive. They came quickly to do the cleaning, and Paul and his assistant were respectful and friendly. As soon as I am able, I plan to go forward adding these upgrades with CAPPS. I like that he is both an owner and a technician, and I was pleased enough with the service to pass on his name to a friend.
