carrier infinity with green-speed
Save your money, There are better options.
The carrier infinity with green-speed might be a good machine at keeping the indoor temperatures steady, but its not going to do what it promise, it will not keep you comfortable better than other machines.
The System is pretty bad at keeping the humidity low (i obviously lives in a humid state)and while "trying" to lower humidity it will freeze you (by quickly lowering the temp. 2-3 degrees bellow your comfort level)the effect is similar to going in and out from a restaurant walk-in freezer.
if you bothered by humidity, you might want to consider whole house dehumidifier, if matched with other good system(without the complexities), it will cost less and work better than the carrier infinity with green-speed. the system have some nice features but none worth the cost and all delivers less than advertised.
since its a new machine, the company who sells and installs it have no experience with its complexities or capabilities and relies on Carrier's exaggerated claims. Carrier itself have little experience with the system and seems stump and unable to help the company that install it, who, by the way, consider the best a/c company in my area, and is NOT cheap. I read many reviews about the system prior to making the decision to buy it but non were from homeowners, they were all from pros who admired the system complexity and claimed abilities.
DON'T BUY IT OR GET A VERY GOOD GUARANTIES.
