I can understand someone wanting step by step DIY advice, but in a couple of situations recently I have seen where HO is broke, wife's sick, a/c's out and there is a free/cheap solution to get me by until work picks up, etc...
Oh, everybody says you should do without for 2 years or mortgage your house for a cadillac system... C'mon -- you wouldn't!
Why not say something constructive... "this could work, that might work but not very well, or here's why it can't." And the can'ts should maybe be a little realistic.
Not everyone is going to or is able to buy the perfect scenario regardless of your opinion, and I'm willing to bet there are a lot of techs on this forum with some frankenstein crap cooling their houses because it was free it can made to work for now!
If you can't be helpful to homeowners who ask legitimate questions on this site then why not stick to the pro-forum and leave 'em alone? Otherwise lets keep 'em safe, keep 'em comfortable, and maybe try to help our industry's reputation out a little. Hell, maybe even get a job or two out of the deal.
End of rant. Thanks for your time.
