Bryant ACs are nearly identical, and cost is slightly lower. Check prices by getting estimates from a local Carrier dealer and a local Bryant dealer.
Another option is to check out an International Comfort Products (ICP) brand like Heil, Day & Night or Tempstar.
ICP and Carrier are owned by United Technologies (UTC), and the air conditioners are almost identical. However, UTC prices the ICP brands lower than Carrier to appeal to a wider range of consumers.
