I have insulated double honeycomb cellular shades installed in houses
in Florida and Massachusetts. In both houses, there was a noticeable
difference in the temperature once the shades were installed. The
double honeycomb design keeps the AC in in Florida, and the cold out,
in Massachusetts. So yes, spend the money on good, insulated
honeycomb shades with the highest e-value rating you can find. Cheap
honeycomb shades that aren't rated for insulation value (without a
posted e value) are probably nothing more than decorative, though.

HTH,

Hi Donna,

Thanks for your response. What did you have in the windows before the
cellular shades?
