I have always heard that for greater effeciency, the factories will up size the evaporator btu over the rated btu of the condensing unit.
I have a person who says in Houston, to alleviate the humidity problem, you should downsize an evaporator 1/2 ton below what the btu rating is on the condensing unit to remove more moisture.
Maybe I am learning something new.
Is this true and why? Thanks, for the help.
