Just finished a big remodel on the house. As a result, I have to crawl
about three times as far in the crawl space to change the furnace
filter. Our furnace guy told me that I could install the filter behind
the grate of the cold air return (the opening's big enough for a 14 x
20 filter; the one under the house is 16 x 20). This sounds great to
me, and a simple fix. Is it as simple as installing a frame to hold
the filter behind the grate?

Thanks.

Yes and maybe no. I did that, and had some fun doing it. I live in an
older home and when I started to put the filter rack (that's what they
call it) in the hall ceiling the blocking that made a box for the return
duct to hook to wasn't square. I had to hack out part of the blocking
to make room for the filter rack. It was about a quarter of an inch
on one end, but it makes a mess when you are doing that sort of thing.

Now though it doesn't take but a couple of minutes to change my filters.
