Definately will go with the 2 stage unit. Here in Tennessee we have a lot of experience with heat pumps. The one here where we're selling is a 3 stage and it's driving 3 dampered zones with separate thermostats. If the demand for heat or cooling is minimal the compressor runs on low speed and as the demand goes up, so does the speed on the compressor and the air handling unit. If you're super insulated it rarely goes to the 3rd stage. The slower the compressor runs the less MW it uses and the saving can be significant. I think the pay back here in TN was 3.5 years. Not sure what FL will be. One other benefit of a staged system is when it's running in low the air coming out of the vents is about half velocity so it's less drafty.
Thanks for the info.
