Why isn’t my smart thermostat controlling the HVAC system (AC, heat, or both)?

Equipment | Thermostat | Troubleshooting

There are a few different things you can check if your thermostat is not properly controlling the HVAC system. 

1. Is your thermostat in malfunction on your app or website? Find more info on thermostat malfunctions here.

2. Ensure your HVAC system is getting power. Please make sure no breakers or switches are turned off that power your HVAC system. 

3. You may need to wait 5 minutes when you switch from heat and cool modes. The compressor will be delayed by 5 minutes. 

If you have checked the above and still need assistance, just give us a call at 1.800.PROTECT (1.800.776.8328). Depending on the issue, our team may recommend you contact an HVAC company. We recommend Armstrong Comfort Solutions for all of your heating and cooling needs.
