Should You Upgrade to a Smart Thermostat?

Smart thermostats offer real benefits, but they're not necessary for everyone. If you have a consistent daily schedule, a programmable or smart thermostat can automatically adjust temperatures when you're away, saving you money on heating and cooling costs. These devices also give you remote control from your phone, which is helpful if your schedule changes or you want to adjust settings before you get home. Many smart thermostat models also provide energy usage reports that show exactly where your money goes each month. 

That said, if you're home most of the time or prefer simple controls, a traditional thermostat works just fine. Our team can help you weigh the costs and benefits based on how you actually live in your space, not just what's trendy. We can also help you access the latest smart thermostat technology, such as Google Nest devices.

Signs Your Thermostat Needs Repairs

Sometimes it's obvious that your thermostat isn't working, but at other times, the signs are subtle. 

Watch out for:

  • Temperatures that don’t match the setting. Your thermostat may say 72 degrees, but your home feels more like 68 or 76. This usually means calibration issues or faulty sensors.
  • Systems that won't turn on or off. If your heating or cooling runs constantly or won't start at all, the thermostat may have lost communication with your HVAC system.
  • Blank or unresponsive displays. Dead batteries are the simple fix, but if replacing them doesn't help, you might have wiring problems or a failing unit.
  • Short cycling. When your system turns on and off repeatedly within short periods, it's often because the thermostat is misreading temperatures or malfunctioning.
  • Higher energy bills without explanation. A faulty thermostat can cause your system to run longer than necessary, driving up costs without improving comfort.

If you're noticing any of these issues, it's time to have your thermostat checked before small problems turn into bigger headaches.
