Where Can You Find a Digital Thermostat?

Major Home Retailers

• Home improvement stores such as Lowe's, Sears and Home Depot sell digital thermostats to work with your home's heating and cooling systems. Although you can visit your local store to browse their thermostat selection, most stores also have web sites that allow you to research options before going into the store, and some stores have staff that specialize in helping with selection and installation of digital thermostats.

Manufacturers

• Makers of heating, ventilation and cooling systems also offer a range of both programmable and non-programmable digital thermostats that you can purchase directly from them; the companies that produce digital thermostats and other control systems also sell directly to the public. Companies such as Trane or Honeywell operate standalone web sites and work through a network of authorized dealers to help you find the digital thermostat you need.

Online-Only Sellers

• Online retailers such as Globalspec and Amazon offer digital thermostats from all of the major systems manufacturers, so you can find a digital thermostat that will work best with your home's ventilation system. Some online sellers also sell the wiring and internal switches needed to connect the digital thermostat.
