I recently checked the Lennox and Trane websites, and both now appear to offer genuine variable speed centralized air conditioning (it looks as though Carrier still doesn't have it). In terms of multi-zoning, that might be the sea change I've been waiting for. Prior to now if you wanted fine grained zoning (where many if not most rooms are on their own zone) for central air, the options for getting it in the United States borrowed from commercial technology that was not within the mainstream for residential HVAC. Previously, the closest substitute I could find would have been a custom chiller system. However, if major vendors are now offering mainstream variable speed central air for residential, the whole thing should become a lot more affordable and easier to get reliably installed and repaired. It would probably eliminate a lot of the custom control and zone automation that would have otherwise been required. I'm excited about this. I really doubt that even best efforts at "balancing" a conventional one or two stage compressor system would come anywhere close to either the comfort or performance of a multi-zoned variable speed system. Has anyone else here given it a hard look?
