Furnace Won't Turn On After Cracked Heat Exchanger Claim in Holly Springs
Holly Springs · October 2026 · Dexter & Mario · From our service records

What the customer reported
A Holly Springs homeowner reported the system will not come on and wanted a second opinion after being told her heat exchanger was cracked.
What we found and did
Dexter and Mario checked the heat exchanger and did not find any cracks. When they turned the system on, the unit would not start and the error code said high limit switch, but all the switches checked good. They found the connection on the board was loose, plugged the connections in good, and the unit started and ran well. The inducer motor was real loud and rusty, so they suggested replacing the board and inducer motor, and the customer asked for a price on both.
Result
After the board connections were plugged back in, the unit started and ran well.
