A smart thermostat learns your schedule and adjusts temperatures automatically, saving 10 to 15 percent on heating and cooling costs. Prices range from $150 to $250 for the device, and installation is a simple DIY project for most homes. Remote control via phone app gives you flexibility when plans change.
In San Antonio's climate, where air conditioning runs 8 months of the year, a smart thermostat pays for itself in 12 to 18 months through energy savings.
Energy Savings Potential
The Department of Energy estimates smart thermostats save homeowners 10 to 15 percent on HVAC energy costs. For a typical San Antonio home with $200 monthly cooling bills in summer, that is $20 to $30 per month in savings. Annual savings total $150 to $300.
