I am a little gun shy on the techs from this vendor. Had I not bought the unit from him initially I would probably use someone else.
Would the patch just be installed with some sheet metal screws? How would it be sealed around the edges?
I have found what appears to the the solution to my problem. I am seriously considering the
Honeywell HM512VPIAQ as the replacement rather than the bypass unit. It requires an even smaller hole (1-3/4") and hopefully it will make it easier to patch. I just hope the vendor is up to the task.
Thanks for the response.
Mike
