Best A/C I’ve ever had
February 21, 2026
I just love this a/c unit. It’s really hit and humid in the South and this unit keeps my house very comfortable. And it’s quiet!
Help

Not working since January 7, 2026, not fixed with many tecnichian attempts.
Good product, BAD installer, lack of support from Carrier Corporate
January 7, 2026
I live in South Texas and have two units. Had this unit replaced 9 months ago for our upstairs. "Carrier Certified Installer" didn't even measure square footage and likely installed too large of a unit. I learned from a bad experience. Now I have a $14,000 unit that doesn't remove humidity from my house and have to run multiple dehumidifiers upstairs to prevent damage to my home. At this point I would not purchase a Carrier unit for downstairs as even corporate has been pathetic in support. It is cool and quiet, but that quietness is overrun by the sound of dehumidifiers.
