Arrived and talked to the homeowner He told me things have been going all right for him in the unit After looking at the air handler and opening it up I noticed a lot of biological growth growing. There is an active 120 V UV light installed in the ductwork in the supply. Due to the age of this unit and looking at how much growth is now occurring highly recommend replacing the system For health concerns alone, and due to The age I tested the turbo capacitor, and it is still within its specs The evaporator coil should be pulled and cleaned with the dirt stuck inside the coil I recommended blower, pull and clean as well An installation of a UV light inside the air handler to stop this from spreading Due to the cost of all the repairs, I recommend a new system System is ready for summer I will be sending over the estimates if the homeowner wants to do any of the repairs in case replacement is not optional Thank you for using Total Air Dan e
