Tech arrived at a membership tune-up. Upon inspection, the capacitor was out of tolerance and was replaced under warranty. The system did not appear to have Surge Protection. The filter was dirty and replaced. The ductwork and blower area was dirty. The drain was clear and bleach was poured. The heating system reached complete ignition. The customer was informed of recommendations today. He will talk to his wife about upgrading to an AprilAire filter. He will call back next month for installation. The system was functioning upon departure.
