Recommend drain pan and condensate line repair or replacement to prevent leaks and water damage.

Performed seasonal heating system cleaning and inspection on one unit, including cleaning of the furnace cabinet interior and electrical testing of control board wiring terminals with a clamp meter to verify proper operation. Noted rust staining and mineral deposits on the drain pan beneath the refrigerant line penetrations, indicating prior moisture or condensate leakage, and recommended further evaluation of the condensate drain and line set connections. Corrosion was also observed at a pipe fitting at the cabinet floor.

Performed a fall tune-up on one heating system, including inspection of the burner/manifold assembly, flue, and internal cabinet wiring and controls. Noted surface corrosion on the burner area panel and mounting plate, condensation on the flue, and dust and debris buildup in the cabinet, and recommend monitoring for continued corrosion and moisture. System components were otherwise found intact with wiring and connections secured.
