What a joker. I would fire you the second you insisted on doing my load calc at 75F and 50% RH. Try more like 65F and 50% RH. As a professional, your first and foremost ethical obligation is to the client and their requirements; if you refuse to do that, you need to find a different profession.

Although I appreciate your passion and dedication to the homeowner, sizing to those indoor design conditions will not help them. I will continue to teach and stick with the International Residential Code, International Energy Conservation Code, ACCA Manual J, and the properties of air (like dew point). Thanks for watching though!

@@HVACProBlog If you know the relevant math and physics, you should be able to design a system to any conceivable requirements. It's not that hard. Whether or not the client wants to pay for it is a separate matter. Personally, that's where I'm comfortable, so I'm willing to pay. In fact, my indoor conditions are 63.5 and 44% right now, and it's perfectly comfortable. I would be covered in sweat at 75 and 50%. I guess I'll stick to more flexible contractors or do it myself; I didn't go through a mechanical engineering degree for nothing.
