Tech Cody Brooks arrived at customer's home. I went to the upstairs unit and opened up the cabinet for the furnace. I inspected electrical connections to the safeties of the furnace and tightened any loose connections. I took a amp reading of the inducer fan motor and it came back below manufacturer specifications. As I was inspecting the evaporator coil, I noticed that the customer didn't have a pan strip, and added an estimate for him. I noticed that the return plenum had some dust and animal hair build up, I made the homeowner aware of this. Overall the system is in good health. I made the customer aware of our membership plan but he was not interested in purchasing it today.
