I consider this a perfect answer to the question posed. If we had more builder/contractors as aware of the work being done by their subs as dx is, we would have more consistantly, properly installed HVAC systems.Originally posted by jultzya
Everybody screws up once in a while, it's how they handle and rectify the situation that would answer that question for me (if, I was in your shoes).Originally posted by dx
But it could have been backwards (swapped intake/exhaust) and I may have missed it. Since it's worked flawlessly all these years, I am only curious from the viewpoint of "should I ever hire this HVAC contractor again?"
Dx, there are a lot of installations out there that have been working despite their improper install. I hear it all of the time; "well, it's been working right all of this time so why should it be changed?" The answer to that of course is; "No, it has not been working right, it has been working despite its wrong installation." Some procedures will not show a problem in 99% of the applications and so that 1%er seems to be unique.
Bottom line; install as per the manufacturers installation literature and you will always be within any local code.
Now! Let's not forget concentric kits which seem to defy some of the physics points I have noted, but in reality are a bit of a different animal where the thermaldynamic laws of physics simply behave differently.
