Aprilaire Home Thermostats

Aprilaire Thermostats control not only your home’s heating and cooling, but your overall comfort.

Few homeowners spend much time thinking about thermostats and which one is right for their home. Perhaps they should, because a properly designed thermostat can do much more than just turn your heating and cooling system on and off. While you usually think of thermostats as just controlling your home’s temperature, at Aprilaire, we view thermostats as your easy-to-use command center that lets you control and customize your entire home’s comfort experience.

That’s why we created an entire family of digital thermostats to meet just about any home’s specific needs. Constructed with the latest technology and filled with Aprilaire innovation, these thermostats give you entirely new levels of control over your heating and cooling system and your overall home comfort.
