There is no actual Carrier Infinity furnace series. Instead, there are several different Infinity series, including the Infinity 80, Infinity 96, Infinity 98 and Infinity ICS.
Carrier Infinity furnaces include condensing and non-condensing units, including the Infinity 80, a two-stage unit with an efficiency of up to 80% AFUE; the Infinity 96, a two-stage, Energy Star rated furnace with an AFUE of up to 96.7%; and the discontinued Infinity ICS, a variable-speed modulating furnace with an efficiency of up to 95% AFUE.
Installed two (upstairs/downstairs) Infinity systems. Top of the line. Units work great, very quiet and comfortable. That being said, we purchased these premium systems to allow for remote access and control. App typically does not work and Carrier server often down. Do NOT buy if you want a unit to control remotely. If no problem having to control only while standing at the thermostat, pretty good units.
"Lots of Problems"
Purchased Summer 2017. Replaced unit immediately after install since malfunctioned. One month later had to replace again for a new unit. Next an exhaust unit needing to be rebuilt. Also not able to easily get settings to meet my houses requirements so constantly freezing up and asking for filter replacement until techs finally figured how to handle air flow. This weeks fun is the smell of gas but no leak.
"Infinity series Air exchange"
System is loud. Customer service is bad: two main things 1. System been installed for a year and still they cannot get the thermostat to work well. 2. They cannot commit to proper service for maintenance. 3. They are hard to reach.

Two repairs in 8 years for a total cost of $ 2456.81, not covered by warranty. Obviously I have a “lemon” Spoke with a senior customer service rep today. Nothing she could do for me. Your product needs to do more quality control . My last outdated furnace lasted for 22 years with only maintenance required not one repair !!!

I am planning to replace my 20 year old quiet Infinity furnace. Though, the inducer is making lots of noise on a regular basis now. The assembly is pricy to replace, seems crazy to spend that kind of money on an older furnace. Up to now, other than regular maintenance, the only cost was an igniter a few years ago. After 20 years, this furnace owes me nothing. Thanks Carrier. Still looking at bids from Amana and American Standard too. Maybe even price out a Trane….
