What is the model of a 3 ton condensor - Goodman CKL42AR42 Air Conditioner

Thermostat is wired wrong on terminals or at inside unit. It could be heat pump

it is a 3 ton condensor you still can buy r22 freon condensors new but they have nitrogen charge and its expensive to charge I recommend to go with 3 ton goodman condensor which is new 410a puron and also change indoor coil and flush the line set so you dont endure the high cost of new copper lines these new systems come with 10 years warranty and the r22 systems come with only five years

no you cannot put a 2 1/2 ton compressor into a 2 ton condensor. you could put a smaller compressor into a condenser and you will gain effeciency put loose capacity

042 is a 3 and a half ton. Take 042 and divided by 12. Is 3.5

That should be a Goodman 3.50 ton unit.

Hello
Find the btus, 6000 btu is 1 ton. So 12000 is 2 tons.

Most home central units are 3 to 4 tons.

If you get the compressor brand and model number, You can call your local parts store and they should be able to tell you.

3 ton unit possibly a 13 seer

I hate to use rules of thumb but 500sqft per ton depending on your windows and insulation. you are probably ok with a 2.5 ton however it will not work with a 3 ton outdoor unit as you have figured out. depending on how long that ac has been in you may want to replace it with a 2.5 ton due to the damage to the compressor valves because of the mis match. or if the indoor is newer and the original system may have been a 3 ton then i would replace the A/H. and be prepared to replace the outdoor if the valves are to far gone. If the trane is a new high effiency 2 and the goodman is just a 10 SEER you may be able to have a txv installed on the trane unit and a kickstart device outside. but only if its a high effiency but their again if the A/C fails you couldnt have a high effiency 3 ton you would have to drop down to 2.5,

Sure but you need ot have an AC man to replace it and vac down the system plust change the dryer/reciever.
