If one follows the app it stops if you've got a dual fuel system and tells you to pay someone to come install it. I've installed many of the Nest thermostats for others w/o dual fuel with no problem. The "recommendation" of hiring pro installation is ACTUALLY a requirement? Ecobee doesn't do this and if I have to spend more for Nest installation, I'll spend the extra on an Ecobee.

Hi Blake23452, 

Thanks for reaching out. If you have a dual fuel system, We suggest to have a trained professional set up your thermostat. It’s important for a professional to assess the requirements for your specific dual fuel configuration since choosing incorrect options for a dual fuel system can result in damage to your system.

Thanks,
