That was also helpful especially without a reason. I'm pretty sure my one
year old, 7K, 2.5 ton system is too big for my 720 square foot house. I had
the compressor and outdoor components exchanged for 2 ton components within
two weeks. The humidity is always in the upper fifties so it never feels
good. Another sign it's too big. Not surprisingly, the blower motor went out
at 12 months. I was lead to believe it was a manufacturing problem. Doesn't
take a genius to figure out a system turning off and on too often will also
cause wear and tear. Which leads us back to the original question....how
short is too short? It was hot here in Chicago yesterday, 85, and my newly
repaired A/C was on 7 minutes and off 7 minutes which I felt was too short.
Still at a loss given the info here. It was hot, am I wrong in thinking it
was too short? BTW, I realize insulation, window and door leaks must factor
in. Four years ago I had 8 inches of insulation blown the attic. My old two
ton A/C never had such short cycles, not even with 4 inches of insulation. I
understand on a hot day 10 minutes on and 10 minutes off or three cycles an
hour could be appropriate from info I got elsewhere. Anyone agree? Comments?
I can't replace worn out parts every year.


I've a question for you. The size of your AC unit seems to be too big for your small well insulated house, did the HVAC contractor do any calculations or take into account the energy saving measures you have taken? I've a few more questions I'm formulating since one of the things I did when I was still working was HVAC system installation and repair. ?(?)?
