A 5 ton unit is sized appropriately for our home except perhaps on a rare night when the temp gets down to - maybe 10 below??? As that almost never happens in SE CT, we’d be throwing money away if we bought any larger unit. More cost effective to just use the electric for those few hours of unusually cold temps. Not sure I answered the question but I’m not an HVAC engineer.
