During my inspection today, the customer allowed me to come inside of her home. She started off by showing me all the equipment. She asked me if I could change her 20 x 20 by one air filter. She also wanted me to inspect her flue pipe in the attic. I inspected the flue pipe in the attic and showed her pictures of how it was connected. The flu pipe did pass my inspection. I checked out the rest of the system. The indoor unit checked out good. The outdoor unit checked out good as well. And I also cleaned the outdoor unit. I am giving the customer the option for a duct cleaning on both sides of the home. It is a two system home. I am also giving her the option to do a dryer vent cleaning on this side of the home as well as the other side. All other information is in my check sheet which I have emailed to the customer.
