Hi folks! Name's Will Smith (not the rich one in Hollywood-I'm the handsome one outside Chicago). Been at HVAC now since '92 (Geez- I sound like an old Winchester), though most of my time in grade has been on roof-tops, built-up splits, boilers, and control work. I've found that although the physics of what we do is all the same, there are enough pyschos to keep us guessing! Looks like this site has a university's worth to learn-looking forward to it all. It's good to be around others with more than a passing interest in the craft-
