Most heating systems in the US are ducted, which has no baring on whether a thermostat will work with the system. The thermostat is looking to talk to the furnace using specific wiring configurations carrying 24v AC power.
You will need to do a little digging to find out if your system is compatible, but a quick Google for Nest's Compatibility Checker is a good place to start.
