Tech arrived at a 2022 AirEase inverter board tuneup. Upon inspection the contactor was in working condition. The board showed no errors. The system had surge protection. The condenser coils were hosed off to assist with air flow across the coils. The filter was dirty. There was a damaged duct that was taped. The blower area was a little dirty. The drain was clear and vinegar was poured. The water heater was evaluated there was rust and corrosion on the tank and fittings. The customer has another water heater that is ready for install. Mark was contacted and the customer was given a quote for replacement. The customer will hold off right now but my call back later in the year. The system was functioning upon departure.
