There is no actual Carrier Infinity air conditioner series. Instead, there are several different Infinity series.
Carrier Infinity air conditioners include the Infinity 21, with an efficiency of up to 21 SEER; Infinity 19VS, a 19 SEER, variable-speed unit; Infinity 17, with up to 17 SEER; Infinity 17 Coastal, a 17 SEER unit designed to withstand salt air; the discontinued Infinity 18, which offered 18 SEER efficiency; and the Infinity 16, with an efficiency of up to 16 SEER.
It's not the unit, it's how it is installed. Recommend Carrier 150%.
"Unit failed and Warranty not Honored"
In 2007, we installed the Carrier top of the line "Infinity" with 2- speed heat pump, 2-stage burner, and 2-speed blower HVAC. In 2016 the compressor unit fan broke loose from the grill with the middle grill bars still attached to the fan, which sliced the internal components and caused the compressor oil to drain out. The Carrier service technician and a second independent technician recommended complete replacement of the compressor unit due to the internal damage. Carrier insisted that their "extended warranty" only covers parts replacement, not the unit replacement, and refused to provide any warranty coverage. Multiple communications with the "Sigler" warranty division, and to Carrier directly, failed to obtain any coverage.

"Bought new Carrier Infinity 4.5 ton unit, including handler, in 2009. This had to be one of the worst investments we ever made."
Worst investment of our lives. Infinity Carrier system is a lemon.

"Poor Product and Service"
Horrible! Do not use Iceman company or purchase Carrier ac Unit. Do not stand by product or warranty. Unit less than 9 years old and have been told leaks 3 different times, replace evaporator and coil 3 times (every 2 years) and none is covered under warranty and fix at a cost of up to $6000.00. Each time got second opinion and all 3 times Iceman was wrong but can't have anyone but a Carrier Dealer work on unit and have to use Iceman because that is who my extended warranty contract is with. Need a new thermostat and can't get one because have to use Iceman who can't diagnose the correct problem because they only diagnose problems no covered under warranty. Carrier won't intervene, won't help to get new thermostat because have to get from a Carrier Dealer. Carrier says can call another Carrier Dealer to see if they will help you but they don't have to because contract is with Iceman and should really deal with them. Wish I had never every used Iceman or purchased a Carrier ac Unit. Have a dual system and other system is a York and have never had one problem with that. Stay away from Iceman and Carrier.
This is a two stage variable speed and the speed never varies. It's so loud we can't hear ourselves talk. The cat runs behind the bed and meows the whole time it is on. We have had two companies look at it and 4 different techs and no one can fix it. The air coming out the vents is not very cold and it has to run all day to get the house cool. This is supposed to be the high efficient model. We cannot turn the heater on in the early morning because the noise wakes up everyone up and again it takes forever to raise the temperature one degree. There is no number low enough to rate this unit, and by the way it's one of their most expensive models.
