One key point is; AC units need to cycle. That's why in a couple places we camped this summer, we had to raise the inside temp to 75 instead of 73 a couple days.
Why?
I think they may have that backwards. Short cycling is bad. It needs to have adequate run times to pull out the humidity. That is why too big a system can be bad.
AS it relates to Home systems, YES, having too large a system for a house, means the system does NOT RUN long enough to remove the humidity/moisture in the house. As it relates to RV's, it is a RARE RV that has too many roof AC's to overcool a RV. If the system is continually running(compressor) in hot weather, that is a good thing. It is doing its job. While it may be best to allow the Compressor to cycle, so you do not shorten its lifespan, that is the RV'ers choice. But there are Thousands of AC units that never shut off in temps above 85 degrees. BUT, having the correct amount of AC BTU's will allow the RV to cool down enough to cycle off. Doug
