He has given me the names and phone numbers of some recent installs. He didn't have any pictures of past installs, but said he would take me to a current install if I wanted.
Can't beat that if he would do that, like my old Dad used to say the proof is in the pudding, you can have folks come out do a Manual D and Manual J and everything most Pro's here "say" they do, but even with all the manual D&J's and whatever other ones exist and own all the test equipment in the world, don't compensate for a good solid nice looking installation, you could still get a crappy installation and have the air flow good.
