As a dealer for Carrier for several years, I can tell you with 100% certainty that Carrier would recommend a full duct system evaluation prior to installing one of their infinity systems. They'd also tell you that an infinity system will not reach maximum efficiency without a properly sized duct system.

Yes, I agree, and sorry to derail this thread. A system is only as good as the duct system. I took a previous post that someone had the impression that the duct designs were different for variable speed heat pumps versus standard single speed units.
A neat feature of the Carrier Infinity line, as you know, is that they will actually do a duct assessment and spit out a calculated duct loss and static pressure and adjust the system accordingly to maximize the performance to what it is hooked up to.
Yes, these systems are going to be far beyond the average DIY’er if something goes wrong. For 99% of my customers, this is not an issue as I get called for clogged traps and the ubiquitous capacitors all the time.
Huge Carrier fan.
