The equipment that is the best value for your particular condition will once again depend on the experienced knowledge and selection skills of the selected contractor to explain and illustrate in graphic terms why that particular equipment application will return the best performance and savings in your climatic and home conditions.
There are scores of equipment combination choices from which to select the one(s) best suited for your conditions. Those best choices are not always the higher-(est) SEER applications. - Darrell
Goodman 13+ seer with a txv.......great bang for the buck. I'd look into Rheem/Ruud also. You can keep your Carrier/Tranes, as they are nice pricey high end units, which cost alot more for service, but do have more comfort options, if that's what you're after(quieter, higher end controls)
If everything was always done "by the book"....the book would never change.
