My Customer's Air Conditioner isn't keeping the beer cold!

I agree, usually the C.U. has a lower capacity is what I have found. But I have to wonder, as you said... if it is due to the smaller condenser coil dims?

Here is an example of some OEM condensing units with High and Medium Temp applications: (some might even work for retarding units?)

Copeland C3DD-1001, 10 hp unit: R-22 refrigerant.

45 degree SST has a rating of 151000 Btu/Hr
25 degree SST has a rating of 106000 Btu/Hr
10 degree SST has a rating of 78500 Btu/Hr

Copeland C3AH-0100, 1 hp unit: R-22 refrigerant.

45 degree SST has a rating of 12200 Btu/Hr
25 degree SST has a rating of 8220 Btu/Hr
10 degree SST has a rating of 4450 Btu/Hr

Both are condensing units.... LOL!
