My new house has a few big windows facing southwest, taking much sun heat in
the afternoon. Have to keep the heat pump working till after midnight to
cool down.

I went to HomeDepot and hoped could find some kind of window film that can
block sun heat - something like we put on minivan window glass. But there
are only some small packs of decorative films available there. Need some
advice on this.

Thanks.
