Excuse me you stupid, m**********ng, daddy's-c*ck-sucking, best part of you ran down your mother's leg piece of shit, but the service co might just assume that whoever installed the thing previously had done the goddamn calculations (that's assuming the bastard that owned the house didn't put it in himself), and if I ask the co "what size SHOULD go in" that is hardly standing over them.
Being involved and asking questions is not the same as strutting around and 'supervising'. I was a professional mechanic, and I know what that's like.
There's a big difference between an involved customer that wants to understand what's going on, and someone that's telling you what to do (service rate is double for the latter group).
You are another alt.hvac retard, ain'tcha, that needs to shit on people to make themselves feel big, so tell me, how's that working out for you? You feel big now, you fucker? Gonna head on over to alt.hvac and tell 'em how you flamed an arrogant stupid thinks-he-knows-it-all ho-moaner? Well, go have fun, scooter, and remember if you keep the beer warm ain't no one gonna want any so you can have it all to youreself, on those rare occaisions when someone actually visits your fleabag sour-stink-of-failure singlewide.
So GO FUCK YOURSELF and head back to alt.hvac and flame the homeowners who mistake it as a group of and for dedicated professionals, as opposed to the pissy little playground for the disgruntled retards that you and others like you have turned it into.
