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.
We bought a Carrier Infinity unit 4 years ago, It is junk. Something is always breaking on it, labor bills are very high, started having problems few months after installed and still having them. We contacted Carrier Corp. several times. They didn't want to hear anything we had to say and would not return phone calls. Just turned on my air yesterday, guess what, it didn't work. Cost today was another $600 in labor bills.

Carrier Infinity – Just don't do it. Replaced 2 units with 2 Carrier Infinity ….. only one of the old units was broken. Assured our power bills would go down 50% …. and they WENT UP over 33% in KW usage and more in $$$. Perhaps I'll contact the parent company, United Technologies. I suspect the parent company does NOT have a clue how many DISSATISFIED and DISGUSTED customers they have. What a way to ruin a Brand Name like Carrier. Our service provider stalled and stalled on getting an appointment with the Carrier Rep – still hasn't happened yet, the appointment was postponed. With a BAD installation, you might as throw your money down a rat hole. Oh, yeah, Carrier, the manufacturer, doesn't really stand behind their product. They pass you off to the Carrier Independent DISTRIBUTOR. That's like GM or Ford ignoring their warranty obligations and you having to rely on your local dealership to HONOR the warranty. Oh, yeah, the unit is VERY LOUD.
