In 2000 I had a power ventilator installed in the attic(roof top),it was a replacement for the old one that was several years old and had started to leak. I'm having trouble with a loud noise that it has started to make. It's a LomanCool Power Vent. The guy who originally installed it is not in the business anymore. Everyone I have called does not seem to have service calls for this problem, i would really liked it checked out or i would like to just turn it off. Is there a switch there and can you recommend someplace that would come to check it out. Any suggestion?
I'm in the New Orleans area
