So Mr. Bill, you would have the jobs reduced to the lowest bid then, correct? If all the HVAC companies are forced to rely on a 3rd party load calculation, duct analysis, Manual 'T' outlet sizing and Manual 'S' equipment selection, what's left except the install? And how does a company separate itself from the rest under those circumstances? By claiming to be better?
One pays for the cost of load calcs by having it done by a professional sales person who works on commission. Make the sale, get paid. Don't make the sale, no pay. And I for one am not about to stake my reputation on someone elses determination of what is a proper load calculation. My company has removed thousands of furnaces, boilers, AC and HPs, by far the vast majority improperly sized. So while you may have a hard time understanding how run a business, some of us have it figured out pretty well so it works for everyone.
If YOU want change, YOU have to first change.
If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!
