If your home’s thermostat is more than 10 years old, it may be time for a replacement. A new thermostat can cost anywhere from $20 to $400, depending on the features you want and the type of system you have.
If you have a simple, single-stage heating and cooling system, you can probably get by with a basic model that costs around $20. But if you have a more complex system – like one that uses multiple stages of heating and cooling or has other special features – you may need to spend closer to $400 on a new thermostat.
When choosing a new thermostat, look for one that’s compatible with your home’s HVAC system and offers the features you want. Many newer models come with WiFi connectivity, so you can control them from your smartphone or tablet. Other popular features include programmable schedules, touchscreens, voice control and remote sensors.
