Peyton was very polite and nice, but he had never seen one of the UV filtering systems like you installed here in May on two of our A/C units. He didn't even try to change the filter on our older unit, until I asked him if he had. I think he was going to leave without doing anything about it, if I hadn't asked him. He said that he had never seen one before, and I fortunately discovered later that he did not install it correctly, so I had to fix it. Overall, I am left to wonder about whether anything else was overlooked.
