Is my system compatible

[Cameron31]

I tried to hook up my nest learning thermostat and it would only blow cold air I’m thinking maybe my system isn’t compatible. https://share.icloud.com/photos/00fC8XUfPWnpShlyi6SyQao4g

Hi Cameron31

I’m here to assist you, please could you insert a picture in the post of your wiring system? to get a better understanding and check if it is compatible because with this link I’m not unable to open it. 

Here's a tool you can use to check your thermostat's compatibility.

Let me know how it goes,
Daniel
