During my inspection today, I found a few things I wanted to bring to the customers attention. First being that the air handler was full of growth. I am giving the customer the option to do a UVC advantage UV stick light to help with this growth problem. I did and found that the indoor unit was not equipped with a surge protection device. I am also giving the customer the option to add that. I am giving the customer the option to also do a duct cleaning if they wish to do so. at this time the system is operating properly. I checked it in both heating and cooling modes. The customer did not go with any options at this time stating that he would have to talk to his wife in that his wife would have to make the decision. I tried to set up a time that I could call them back and talk to her about the options but he said she has a odd schedule and has no idea when she would be available to talk
