For the super tune-up I inspected the air handler and condenser. All equipment was measuring with a manufacturer specs and running well. Inspecting the air handler the drain line does not have a secondary nor does it have any water safety. I highly recommend to the customer getting some sort of water safety whether a wet switch or float switch to prevent drain line issues and water damage. Additionally I recommend a UV system to eliminate biological growth, as well as replacing the defrost control board soon as there are hot spots which is a sign that board could fail. Lastly I recommend to the customer a membership, and I explained the benefits of being on a membership.
