Hey Ed, What’s the Smallest Size Room That Requires a Supply?

In This Edition of “Hey Ed,” Ed Discusses What’s the Smallest Size Room That Requires a Supply

Hey Ed, what's the smallest size room that requires a supply? That's an excellent question, and I think it's been asked as of late, and I'll be very blunt. I can't remember if it's going in Manual D® or Manual J®, and if I had a guess (and that's what I'm doing right now), I believe it's in Manual D® when it gets updated in this next cycle. And the number that was chosen was 300 square feet. And that's the way I see it. BTUs. Damn it. 300 BTUs and that's the way I see it. :)
