Wake Forest · August 2026 · Mario · From our service records

What we found and did
At a home in the 27587 area of Wake Forest, Mario accessed the attic where the furnace is located and tested the operation of the bypass damper. He confirmed that it had completely failed to move. Mario replaced the faulty bypass damper assembly with a new one, tested the operation of the new damper, and properly set the system static pressure.
Result
The system was operating and cooling properly when Mario finished.
