If you’re tired of heating an empty house or manually adjusting your thermostat daily, upgrading to a smart thermostat is one of the few home improvements that can pay you back every single month. Heating and cooling often make up a large share of utility bills, and small inefficiencies quietly cost homeowners hundreds each year.
A smart thermostat helps reduce that waste by automatically adjusting temperatures when you’re asleep, away, or simply don’t need full heating or cooling. The right model, installed correctly, can deliver real savings without sacrificing comfort. On average, smart thermostats save homeowners $180 per year or $1,800 over ten years.
If you’re tired of wasting money on unused heating and air, check out the best smart thermostats homeowners choose most often, what they cost, and how to install them safely to maximize ROI.
Key Takeaways
Smart thermostats can reduce heating and cooling costs by cutting wasted run time
Most popular models cost less than a single season of energy savings
DIY installation is usually possible, but wiring compatibility matters
Rebates and utility incentives can significantly improve ROI
Correct setup matters just as much as the thermostat itself
Why Smart Thermostats Save Homeowners Money
Traditional thermostats rely on manual changes, which means systems often run longer than needed. Smart thermostats automate those decisions using schedules, occupancy sensors, and learning algorithms.
Typical savings come from:
Lower temperatures while sleeping or away
Reduced run time during mild weather
Avoiding heating or cooling empty rooms
Over time, this reduces energy use, wear on HVAC equipment, and the risk of surprise utility spikes—small changes that add up year after year.
💡 Pro Tip: Savings vary by home, climate, and usage, but many homeowners see noticeable reductions within the first few billing cycles.
Step-by-Step: How to Install a Smart Thermostat Safely
Turn off the power to your HVAC system at the breaker
Remove the existing thermostat cover
Label existing wires before disconnecting
Mount the new base plate and connect wires
Attach the thermostat and restore power
Follow the app setup instructions carefully
Always stop if wiring doesn’t match the manufacturer’s guide—some systems require professional help.
