Most people don't think about their thermostats until they stop running efficiently. When a homeowner wakes up to see their breath in front of their face by not setting it the right temperature over winter, or is bowled over by an unexpectedly high power bill, they'll become aware of the situation.
More typically, though, home thermostats gradually lose accuracy over the years, and electricity bill prices gradually rise without occupants realizing that it's not just the cost of electricity that's increasing, but also the amount they're consuming as well as other common thermostat mistakes.
