The cabinet of my new air handler installed 2 weeks ago is sucking air. The leaks are making a whistling sound. My contractor wants to seal up with metal duct tape.
I told him I did not the problem fixed with duct tape, that I wanted the cabinet taken apart and reassemebled correctly.
Is the use of duct tape a standard fix for this or the lazy way out? I just want to know if I am being too picky, I spent a lot of money on this system and I paid to have it done right.
