Smart Thermostat FAQs for Michigan Homeowners

We highly recommend smart thermostats like the Lennox iComfort or Ecobee. They can automatically switch between heating and cooling, which is essential during those Michigan weeks where it’s 40 degrees in the morning and 75 by afternoon.
Yes! With a Wi-Fi enabled thermostat, you can monitor your home’s temperature from your phone while at the lake, ensuring your pipes don’t freeze in the winter or your AC isn’t running needlessly in the summer.
While we prefer to provide and warrant the high-quality thermostats we sell, we do offer professional installation services to ensure your smart thermostat is wired correctly to your specific HVAC system.
