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.
I see lots of complaints with Carrier here, but nowhere do I see any complaints about the hvac company that installed these units – which is more than likely the culprit. Did the hvac company just install the unit without checking the existing duct work? Was a load calculation done to determine the proper size of the furnace? Were the installers nate Certified? If you answered no to any of these questions the onus is on you for your miseries. Cheap installation prices has never produced satisfaction regardless of brand. As two year owner of an Infinity system I have had zero issues, but then again I hired a good installer and I have my system checked yearly – are you?

"Infinity Series problems"
Installed new furnace and a/c 6-2010.On 9-2010service for blown fuse.Rewire by service man. 5-2011 service call, tech says bad relay, problem goes on for a month. Technician here twice more. Finally 6-2011 new control board installed. New thermostat 1-2012.My charge New humidistat 2-2013.My charge Inducer motor sounds like a jet engine spooling up for take off. Tech comes takes unit apart.Checks everything. Puts back together. Sound gone. Nobody knows why and my charge. Now my last furnace only lasted 24 years and in that time was checked twice and cleaned once. Regular stuff. That furnace was a Bard.
Piece of junk. Have had the system since house was purchased new (7 years ago). In total have had service down to look at it 5 times. Two years ago motor in the hrv failed, motor just failed again. Bill is $844.00 Only thing worse than the Carrier unit is their customer service. All I got to talk too was too ladies who’s only experience in the industry is to provide lip service too people who are dissatisfied with the product. Got a call from Carrier rep saying sorry off of warranty. Bad luck two motors going in under two years. Merry bleeping XMAS to you too Carrier. BUY AT OWN RISK!!!!!!!!!! At least at Sears you can buy extended warranty.
"Carrier Infinity, has fatal flaw, do not buy"
Replaced my 12 year old unit with carrier infinity as suggested by SMO DMO of Maryland. Unit was installed end September, it was warm started ac and unit failed has to call repair, replaced outside unit thermostat which failed in new unit. Cold started and switched to heat, oh my it was shoecker. message unit flashes ” malfunction “. Had 5 calls for repair, at least 8 different technicians have come and cannot figure out what the problem is. Still have a brand new carrier infinity malfunction which no one knows whats wrong and how to fix. I made a fatal mistake for buying carrier infinity please do not buy this unit even if selling hvac tries to talk to you into this unit.
"Furnace ate a bird, but otherwise wonderful"
Company who installed missed the birdblock on the intake and my furnace ate a bird right away and died, however, the installing company replaced the inducer for free and have had no other issues with the furnace whatsoever. Having a staging furnace is awesome!
