Thermostat repair and smart thermostat installation in Los Angeles
A thermostat problem can look like a broken AC or furnace. Blank screens, dead batteries, loose low-voltage wires and a missing C-wire are quick fixes — and when the thermostat is fine, the technician moves straight on to the system.
Repair and wiring
We test the low-voltage circuit, the transformer and the wiring to the air handler, replace failed thermostats and add a C-wire or adapter where a smart thermostat needs one.

Questions about thermostats
My thermostat is blank.
Batteries, a tripped float switch on the AC drain or a blown low-voltage fuse. All are checked on the visit.
Will a smart thermostat work with my system?
Almost always. Heat pumps and multi-stage systems need correct wiring, which the technician handles.
Is thermostat replacement included in the service call?
The $69 covers the diagnosis and is applied to the replacement if you go ahead.
