Heat Not Coming On in a Chapel Hill Apartment
Chapel Hill · October 2026 · Bernard, Jeorell, Mario & Dexter · From our service records

What the customer reported
The heat was not coming on in a Chapel Hill apartment.
What we found and did
Jeorell and Ben found that the W wire was receiving 24v when it was not making a call, and all the wiring in the bundle was touching and getting voltage. They checked all the low voltage wiring, then replaced the thermostat and tested operation. The W wire was still getting 24v when it was not supposed to, so the outdoor thermostat wiring will need to be replaced, along with the fan relay.
