    True. You simply don't plan for average weather, unless you prefer to do that.

    Then there is the case of the statistician who drowned crossing a river with average depth of one foot.

    Also keep in mind, for example my climate. We sometimes see summers that top 100 F maximum daytime. Normally just the the 90's though. However, our winters almost always dive into the 20's. So if I design a unit with cooling in mind, I have a temperature differential of 30 degrees for cooling, for 70 F. However, if I want to maintain the same 70 F in the winter, I have to pump as much as 50 degrees difference. You simply need a unit capable of mixing twice the heat in the winter than the summer. Size it for the worse differential.
