As a guess I would say to large. But they might have just pulled an old 70% or less efficient furnace that was 75k Btu and just replaced it with the same size not taking into account the output BTU’s. The size of the A/C is typical for that size furnace.
Charley, let me guess, was the home a mid 1980’s? I see that a lot here at the Jersey Shore. Did you have a chance to IR the envelope? Again, 1980’s homes in my area have very poor insulation installation-gaps, voids, misalignment, missing, and of course, no pull-down stair cover.
Lmao…you guys go to a ton of trouble for this problem.
I probably would just look at all the other systems there, most condos are similar or can be figured out which ones are similar and look at those sizes and check consistency.
If they are built the same, then it should be very similar in size.
Did you read the original post? It was installed within the last 30 days. Just would make my case even a little better if 40 of them were 1.5 ton units…and this was the only 2.5 ton unit.
