    3 ton smaller than 2 ton???

    I got a Carrier heat pump installed last year that was supposed to be a 2 ton unit (for downstairs). I just got another Carrier heat pump that is supposed to be 3 tons (for upstairs) but it is shorter than the 2 ton unit (same width and depth on both).

    2 ton unit: model # 25HNA624A300
    3 ton unit: model # 25HNA636A300

    Can a 3 ton unit be smaller than a 2 ton unit???

    That's the reason,if you don't understand the double row coil,it's double thickness ,compared to single,so the three ton has more outdoor coil,in a shorter cabinet.

    Cabinet size isn't always indicative of size. I've seen small, large-tonnage units before.

    The model number tells you the capacity.
    See the 24 before the A300 in the first one?
    See the 36 before the A300 in the second one?
    That is capacity in BTU/hr times 1000 so you have one 24,000 btu and one 36,000 btu condenser.
    One ton of air conditioning = 12,000 BTU/hr....or the amount of heat it takes to melt 2000 pounds (one ton) of ice in 24 hours.

    Size changes. Believe the model number for capacity.
