Service Overview

The smallest part of your system, and the easiest to get wrong.

A thermostat installation looks like a five-minute swap, until the new unit will not power on or the heat pump runs backwards. Heat pumps, multi-stage furnaces and systems without a common "C" wire all need specific wiring, and a wrong connection can damage the control board. We install smart and programmable thermostats, add a C-wire when needed and set up the schedule so it actually saves money. We also handle thermostat repair, which often turns out to be a wiring, sensor or control-board issue rather than the thermostat itself. If the thermostat checks out but the system still will not respond, our AC repair team can diagnose the equipment.

Common causes are dead batteries, a tripped breaker, a blown fuse on the control board or a clogged condensate safety switch cutting power.
