Sure you're

BTW, it remains to be seen that I'm wrong on this subject. We will likely never know, as I doubt a Manual J will ever be completed on his home to find out. But if I am, you better enjoy, cuz it doesn't happen often.

Ok, Manual J mentioned. I've been told in the past, if you are getting a system installed, to request a Manual J be performed first. If the tech won't do it, run. What say you?

If you're going to install a system:

1) Run a Manual J 'load calculation' to size the equipment properly.
2) Do a Manual D to properly check/size the ducting.
3) Install to code and manufacture's recommendations.
4) Set-up the equipment to operate with-in the manufacture's specifications.
5) Register the equipment for the additional extended factory warranty.
6) Enjoy your new comfort system.
