Performed diagnostic on 9 year old 80% furnace, customer stated that there was a squirrel in attic that may have chewed up duct, found small rip in return duct, as well as 6” supply duct that was disconnected from supply plenum, recommended replacing 6” duct, we did give a bandaid repair option on reconnecting duct, however it would be best to replace duct. Unit has float switch however float switch looked like it has been damaged likely due to an animal chewing switch, recommended adding wet switch in system to avoid any water damage, homeowner was in and out of meetings blower wheel is a little dirty filter will need to be replaced, recommended homecare as well as UV protection for system, we did not pull any tools off of the truck, homeowner stated she was not interested in homecare or any UV protection and that she was going to call around for different prices to repair/replace duct
