"Brilliant – No Heat Exchange concerns here"

5.0 rating
Very Satisfied

My Carrier Infinity furnace installed by Sears has been amazing. Quiet, very efficient on electricity (true ecm Variable Motor, not x13 dc which uses twice as much electricity) The alarms when off about the heat exchanger issue, but when I researched more, I found the law suits were thrown out because the failure rate was far less than most other brands, and it seems it was just a greedy litigious American who started it all; someone who used propane in a natural gas furnace (burns hotter)and refused to take responsibility for their actions. Typical “not my fault” law suit. In any Case Carrier as waged the consumer fear by making the Warranty 20 years labor and lifetime parts in the heat exchanger in question. I understand they don’t use that style heat exchanger on the 2012 furnaces. Kinda wish I held off for the full modulating Infinity now. 60 stages! Carrier and Sears are companies with reputations to defend, so I will always go back to a company with longevity. And they took our a Hydro Permit for the job. Didn’t know I needed one, but the ESA and your home insurance will tell you otherwise. Plus I get lots of perks from Sears. I hear the Infinity series have 12 years parts and labor now. Can I trade up Sears?


"I’m Cold"

It was in the house when I purchased the house. It isn’t very old it was a selling point of the house — the furnace came with all the bells and whistle. I have had the repairmen out 3 times for repairs I have even had them come out and do a maintenance check before winter. Now again I’m without heat. I will have to decide in the next 24 hours to repair or replace. It will depend on the cost to repair this time. In the last three years I could have bought a new one.

We have 3 Carrier MVC80 furnaces in the house with Honeywell electrostatic air filters. As of now 2 of the air cleaners failed, transformers burned out, and 2 inducer motors on the furnaces have failed. Far from impressed. Stay away from Carrier, their quality control is terrible.


"Carrier is the problem"

3.0 rating

I bought a Carrier Infinity, furnace and the and I had a couple of problemsimmediately after install. First of all the contractor did not properly slope the Exhaust vent. Water was pooling in the vents runs. The next thing was the noise. Carrier says theirs are the quietest…yes the quietest when they don’t come on! the noise from the air flow was horrible, it whistled through the vents, found out the unit wasn’t set up right. Even after setup it still whistled. The fancy infinity control that Carrier says you need to buy, dont. A Carrier tech told me the infinities work well with any thermostat, in the Carriers it’s not the actual control, but the control board in the furnace that does all the work. Its only marketing. The tech blamed Carrier for a lot of the problems he faces because they will give dealarships to anyone, all their interested in is moving boxes. So dont believe the hype and make sure you buy from a real HVAC contractor,

I bought a carrier infinity system now 3yrs old. the first year i bought it the tvx valve thing went bad. so they had to order it. so i only had to go with out cooling for 3wks with my new ac. then the following year the coil in the attic leaked freezon. so after paying for some freezon and a week later for a coil to come in, i had pay 550 for labor. not a bad deal seeing as how the coil lasted two months and the new one started leaking!!! so after paying for freezon again they replaced it no labor. the winter time rolls around and the sensor thing in it is bad they tell me and wont heat. they replace the sensor thing and it still doesnt work!!!!! the tech then says he has to replace the wall thermoatat and the board controls in the indoor and outdoor unit! wtf? the unit starts to heat for once. i asked what the problem was and the tech says dont worry about it one of the parts fixed it. i was told that its normal for these units like this to act up. well i wish it was normal for them to work properly!!!!!! i have a 4 yr old goodman upstairs. i had one part go bad. they charged 75 dollars labor and no problems since. i could have bought a goodman for what ive paid out in labor and service charges so for to get my carrier to half ass work so far!!! not happy at all!
