I was hired by a homeowner to evaluate a geothermal HVAC system being installed by a BPI Gold Star contractor. I was aghast at how horrible the duct system was installed. I had the homeowner pay for an independent 3rd party evaluation of the duct system performed by a BPI certified employee of a BPI accredited company that also does HERS ratings and compliance testing for Energy Star, LEED and other programs, so there would be no question of the validity of the report. The system failed every benchmark.
I contacted BPI as I thought that they would be interested in the fact that one of their accredited contractors was doing such bad work. The people I talked to there were only interested in knowing if the contractor and homeowner were able to settle. Since the homeowner owed the contractor more than it would cost to fix the ductwork and other installation failures, she was able to reach an agreement. The problem is that this contractor continues to deliberately install ductwork that does not meet any BPI standard on every job. The owner was overheard telling a new hire, "forget about what I taught you in class." I have seen multiple jobs completed by this BPI accredited company and not one of them meets BPI standards.
As long as BPI does nothing to police its contractors, and allows them to game the system, then I question the reason for their existence. One of my go to BPI accredited companies is no longer paying to be accredited and will not renew certification. He sees no value in being associated with BPI. Is BPI a bloated agency that has not teeth and no value?
