This AC unit is beyond amazing! If you can get it for $7600-$9,900, jump on it immediately. I have a new 4-ton model and it is awesome!! We bought the matching furnace and Smart thermostat too. It certainly has beat my expectations. It really does run in stages 1 and 2 nearly all the time. We have it on constant low re-circulation and it is keeps the temperature pretty much even in ever room in the house and has to run the compressor less because the coil is still cold and spreading it around and in the return air. The thermostat can be programmed to put your energy costs for kWh and Therms used, so it will do the rough math on how much energy it is using. The constant re-circulation makes a huge difference and is like 1-2 kWh per day. Super efficient variable speed fan!. I wish there was a setting to allow for more humidity. It is so dry here in Denver and could use some more, otherwise, everyone should look into this setup.

Good stuff! I love the VS series!

I had a complete HVAC upgrade to my home by Bardi Heating & Air, consisting of the Carrier Model 24VNA9 Infinity Series 5-Stage Inverter Variable Speed Air Conditioner, and the 80% AFUE Infinity Series Gas Furnace 2 Stage. The Installation was done July 19, 2023. I was told that the "ZONING SYSTEM" which allows the system to run at 5 speeds and connect to the Infinity WIFI System Controller, was back ordered, so to this point the system is using the old original thermostats, and only single stage. I was later told that other people, who had the same unit installed, have been waiting 6 months or more to get the Zoning System for their units. Is there a wide spread shortage of these things? Why is it so difficult to get them?

Will the 19VS operate at 25 per cent for all sizes like 3 or 4 or 5 tons?
