I have double filters on my unit


That doesn't starve the unit of return air feed?

I know from personal experience, if a unit starts freezing up routinely there's likely a refrigerant leak (too cold on the colds and not enough air flow to get rid of condensate so it freezes up and it enters into a constant state of freeze up and re-freeze until the coil is a block of ice) then the only thing you can do is run the fan itself with no A/C to defrost it..and you better hope your condensate pan is big and your condensate line is not plugged up.

Apparently not since it's been like this since day 1. The pleated filter is in the return air grill and my unit is one of those in the closet type with the return air under the platform the unit sits on.

The hole cut in the bottom of the platform to allow for the return air also has one of those green coarsely woven filters that I remove and clean when I replace the filter in the RA grill.
