CoolAir Inc uses exclusive software algorithms running inside the Nest thermostat to automatically lower air-conditioning costs. CoolAir Inc only works in homes that have air-conditioning. ... Your air conditioner is made up of two energy consuming parts: the compressor and the fan.

The 2nd gen Nest Thermostat works with advanced air conditioning systems that have their own dehumidification mode. The Nest Thermostat’s Cool to Dry feature gives you more direct control of your air conditioner’s dehumidification mode.
