Tech arrived at a tune-up. Upon inspection the system has a low side sat temp around 32 degrees and the pipes were freezing. The Superheat was 1 degrees indicating a possible overcharge. There may be a restriction in the lines. The contactor was scorched. The ductwork and blower area was very dirty. The furnace control board had dust on it. The heating system reached complete ignition. The flame sensor was scorched. The filter was dirty. The customer was informed of recommendations today. He is not able to move forward with repairs or replacement at this time but decided to add a Home Budget Membership. He would like the plumbing evaluation to be performed as soon as possible as he is having lighting issues. The system was left in the off position to avoid further damages. He will call back in at the end of summer to approach further system needs.
