I work for a small mostly commercial company. Less than 10 techs. Yeah you can see the attitude from some of the guys that work for the huge companies. The good ones don't act like that though. And I have seen attitude from small company guys too, especially if they are older than me and thus assume they know more and do better work.

Another interesting aspect is that in the current economy, with a lot of large manufacturers and plants shutting down, some of these huge HVAC companies that specialized in industrial stuff are having to do more commercial and light commercial work. Funny how they talked down to smaller companies because they worked on bigger and better things and now here they are on the roof next to us.
