The customer called because the heaters weren’t working—even though everything had been working fine last season.
When we opened up the thermostat, we found disconnected wiring and a thermostat that had definitely seen better days.
We replaced the defective thermostat, made new connections, tested everything, and made sure the panel was properly labeled so the homeowner knows exactly which breaker controls the heat in each room.
Another troubleshooting job complete.
