3.5 ton
Thanks HeatpumpMan!
The 511 is 4 ton unit. If it was 3.5 ton it would be 461
Is 311U a 2 ton and 411U a 3 ton? Just curious.....thanks
Look at the nearest 1/2 ton and round up.
30,000 round up to 311 for 2.5 ton
36,000 round up to 411 for 3 ton
Of course without knowing exact evap match and looking at the ratings, could be a several thousand BTU range on any size.
