Troubleshooting &d Repair

Not every faulty thermostat needs to be replaced, especially if it’s a relatively new unit. You can troubleshoot by:

  • Adding new batteries
  • Restarting the system completely by using the relevant circuit breaker
  • Using the reset option on the unit
  • Double-checking all settings

Once it’s time to call the professionals, our team can ensure it doesn’t need recalibration due to problems with the thermometer or adjustments to loose or disconnected wiring.

Benefits of a Wi-Fi Thermostat

Many homeowners are upgrading to smart or Wi-Fi thermostats in recent years because, unlike other smart devices, Wi-Fi thermostats offer real, tangential benefits to your energy use, comfort, and more. You’ll enjoy:

  • Remote access while you’re out of the house or in bed, allowing you to drop the temperature for better sleep or keep the temperature a bit warmer while you’re at work
  • More detailed breakdowns of energy use and cooling habits throughout the day and year
  • Alerts to unusual behavior or problems so you can stay ahead of any potential issues
  • Easier to understand and operate controls compared to similarly feature-rich analog thermostats

Frequently Asked Questions

Can a thermostat turn on without batteries?

Often, a thermostat will still show something on the screen even though the battery is too low for it to perform correctly.

Are Wi-Fi thermostats the same as smart thermostats?

A Wi-Fi thermostat allows remote access via internet devices, like an app on your phone or computer, while a smart thermostat might have features for automated adjustments. The two frequently overlap, and the terms are sometimes used interchangeably despite the technical differences.

Does my thermostat need recalibration?

Thermostats can end up out of calibration, meaning it misunderstands your home’s temperature. Depending on the make and model, this can sometimes be easily corrected. In more serious cases, a professional will need to handle the repairs.
