That's my whole point. Energy star and DOE focus way too much on the box because it's easy to regulate. Instead they should be focused on delivered home performance. By limiting BTU per sqft that foces the install to be done correctly and the home to be reasonably tight. OR DOE/ES could regulate WATTS per sqft. Higher SEER or a tigher house could be used to achieve the minimum energy standard.
I agree. Enforcing 14 SEER units in the South, though not easy, would probably be much easier than enforcing a specific BTU on every single home.
Not only is it impossible to enforce its wayyyy to much gubment. I think if you want an inefficient home or don't care who's the gov to tell you you can't. Same goes for if I want to drive a 50s Chevy that gets 3mpg I can.
Why does the government need to be involved in the HVAC trade at all? All this talk about minimum SEER units while "13SEER" R22 units are flying out the door at the supply house. Dry units are almost always hooked to mismatched coils, and there goes any SEER rating that might have been stamped on the condenser. Really, how many dry units are connected to ARI matched coils?
