If you’ve lived through even one Arizona summer, you already know your air conditioner works harder here than almost anywhere else in the country. With temperatures soaring past 110°F, every degree you cool your home matters. That’s why more homeowners in Gilbert and the surrounding East Valley are trading old thermostats for smart, energy-saving ones—and the difference is bigger than most people expect.
At AC Kings, we install and service all major smart thermostat brands, and we’ve seen firsthand how much comfort and cost savings these devices can deliver in our desert climate. Here’s why upgrading your thermostat is one of the easiest (and smartest) HVAC improvements you can make in Arizona.
