Outdated thermostats are inaccurate and can cause excessive runtime shortening the life of a system. Not only can they be an eye sore for an updated home, they are often difficult to read and operate. With a variety of digital programmable stats, you can reduce operating cost with Adaptive Intelligence Recovery technology. Outdoor air temperature sensors can also be installed to communicate with the thermostat, making your system operate more efficiently. Some utility providers offer rebates for qualifying thermostats.
