An ecobee thermostat lost WiFi connectivity despite the homeowner's troubleshooting attempts. The unit was under warranty and had been in service for approximately one year. Upon arrival, the technician found the thermostat was cycling through a calibration sequence but failing to reconnect to the network. The issue wasn't the home WiFi. A firmware corruption had locked the device into a diagnostic loop. Riley Plumbing Heating And Air replaced the thermostat under the manufacturer's warranty terms and restored full connectivity. The new unit was configured with the existing HVAC system parameters and verified operational across heating and cooling modes. Smart thermostats offer convenience but can develop software issues that manual thermostats never encounter. If your HVAC contractor-installed thermostat is malfunctioning and you're still within warranty coverage, call now to schedule a diagnostic visit.
