I also like Carrier.

If you are new to shopping for whole house air conditioning, there are additional factors. Such as dehumidification and, possibly critically the ability of your existing ductwork to deliver the cooled air to the necessary area is the house. And draw the warmest air into AC system.

AC turns a traditional ducted furnace house heating system upside down. The return air ducts in a heated house tend to be near the floor (aka cold air returns). Cold air tends to travel downhill so the largest capacity cold air returns tend to be low on the main floor.

In a house with AC running you want the return air intakes to be high in the rooms, ceiling intakes or high on the walls. Hot air tends to rise so if you have a two story house you may want the largest return air draw from the highest parts of the house.
