Does anybody have a link to a manual heating & cooling load

I
want to size a mini-split system for a 20x30 detached garage addition.
All
I've found on the web are offers to purchase load calculation s/w.

That's 600 square feet and NOT a standard home. I suggest you do 2
tons (24,000 btu).

But if you like it to get cold fast, then 3 or 4 tons.

If you just want to remove the humidity and cool it to 80 on a 95
degree day, then 1 1/2 ton (18,000 btu) will work just fine.

In other words, forget the calc. Completely useless. The important
question is to ask the owner what he wants to accomplish with his AC.

Whos ass did he pull those numbers out of??

Better check with the local inspectors and permits department. Most likely
they will require a Manual J heat load and loss calculation in addition to
the plans for the structure modifications.

Here in my neighborhood, if we see a inspector on our property
talking about permits, we kill him. It is not against the law here.

When I see a city inspector, I shake his hand and thank him for holding the
hacks feet to the fire and helping to raise the quality bar. I then ask him
if he is up to par on the new batch of hacks thats coming out of the
woodwork. Does he know about XXX job??

No I don't just drop dimes, I drop dollar bills. If I have to play by the
rules, then its only fair that everybody else should be doing the right
things right too. That includes pulling permits and having inspections done.
