Rust on Two Furnaces Found During a Cary Tune-Up
Cary · November 2026 · Dexter & Jeorell · From our service records
What we found and did
Dexter and Jeorell found a partially clogged heat exchanger on the first-floor system that requires replacement, and visible rust spots on the heat exchanger of the second-floor system. They inspected and cleaned all components on both systems and checked flame sensors, hoses, capacitors, blower motors, heat exchangers, and gas pressure. They inspected the rusted areas on the second-floor system but could not identify any cracks at this time. Both systems showed an abnormal amount of rust and deterioration for their age, and the crew noted excessive humidity in the crawl space may be contributing, so they recommended having the crawl space evaluated and sealed to keep out outside air and excess moisture.
