Tech arrived at a membership tune-up. It was raining. Upon inspection the capacitor was within specs. The co tractor was in working condition. The refrigerant pressure and Delta was low. The drain was clear and bleach was poured. The heating system reached complete ignition. The system was leak searched. No leak was found identified at this time. Wet coils can affect the leak search. The ductwork and furnace was dirty. The customer was informed of recommendations today. He will wait until the system fails. He is aware that it may be sooner than later and will budget for repairs/replacement. He decided to add a drain treatment strip to help keep the drain system clean. The system was left in the Off position to avoid further damages.
