Lightbulb Insulating around A/C Air Handler in Attic

In the house we moved into this year, our A/C air handler is in the attic and this past summer it did not keep up with the cooling needs once temperatures climbed into high 80s and beyond.
There is air circulation in the attic, but I am trying to make some improvements there. I am also going to put in more insulation and hope to seal the attic better and I was wondering if it is possible and practical to build an insulation box around the air handler or should I be concerned about air circulation or other issues? (Note: air handler is only used for cooling in the summer, I have a separate boiler that provides hydronic baseboard heating.)

The unit is insulated on the inside so adding more won't help! I'd start by getting a heat load done on the home so u know what size equipment u need. Sounds like you'd unit is to small
