Thermostat Repair FAQ
Thermostat repair questions
Often yes — it can be dead batteries, a tripped float switch, or a blown low-voltage fuse on the furnace board. We find the cause and get it back on.
Absolutely. We install and wire smart thermostats, add a C-wire if your system needs one, and make sure it controls your heating and cooling correctly.
It could be the thermostat, the wiring, or the equipment. We test the thermostat and the low-voltage circuit to pinpoint whether it's the stat or the system.
