Two year old system consisting of Amana gas furnace and Bryant a/c with N coil. Since day one I have complained the blower appears anemic when compared to previous unit, dealer doesn't think that a valid complaint.
The evap. first froze over last month, thinking the blower to be slow I called the service man out after confirming the blower is wired for the fastest of the four speeds available. He found system measurements within range and attributed the freeze over to a loose piece of insulation in the coil hood blocking airflow, sounded reasonable at the time. Fast forward to very little a/c use in between, today the evap. froze over again. Just before the first freeze over I had installed a DuPont Ultimate 9600 Allergen filter. Took it out after the problem today and have yet to have another freeze over yet (It's only been four hours). Have others found the above filter in like new condition to be too restrictive on other furnaces? If my blower is up to spec should it be able to function as designed with this filter?
