If you can see the supply duct work, and it is indeed zoned, there should be some sort of electric motor visible from the outside of the duct. Sometimes there are 1 or 2 large dampers and sometimes there are a bunch of smaller dampers for each individual supply run. Pictures would really help to confirm. Models of your furnace and AC would also be really helpful to determine what features/functions they have. Because you already have 2 thermostat it is likely that you have zoning. The NEST and Lyric thermostats would work but you would definitely need 2. Some other brands include sensors that are controlled by 1 central thermostat. Models of you existing system will help determine.
