Q: I'd like to put in a new programmable thermostat to better control my energy costs. Can I install it myself?
—Sam Aleksy, Chicago
Lance Marques, HVAC contractor, Swezey Fuel Co., replies: Sure you can. Upgrading to a thermostat that automatically changes the indoor temperature setting is fairly easy, and it can trim about $180 off your annual heating and cooling costs, according to the EPA.
Simple models that only control heat are sold at home centers for around $25. More expensive products, such as the Honeywell Prestige that I installed here, handle many more functions, including cooling and humidifying. Typically they're purchased through and installed by HVAC contractors, but you can also buy them online.
Before you buy a replacement thermostat, however, take a peek at your existing wiring. If there are only two wires, the simplest solution is to get a replacement with a battery-powered display. Full-featured devices like the Prestige need power from a third wire, something best installed by an HVAC or electrical contractor.
