摘要

The advantage of a programmable thermostat is that it can keep you comfortable and save on energy costs-significantly, if programmed with aggressive temperature setbacks when you're asleep or away. At big-box home-improvement stores, you can choose among 20 or more thermostats that range in price from $20 to $100. Add in a handful of models available through HVAC contractors, with top-end thermostats running from $250 to $700, and the choices can be bewildering.
