Is owner in CT obligated to allow contractors to install gutter heaters?

I am paying a special assessment for ice damming repairs, including attic insulation, and heater cables in gutters. I already had my attic insulated. I don't trust the electric company installing the interior heater cable switch.

Can I decline the attic work, and heater cable work? I do not want the money back, I just don't want the contractors involved in my unit.

The developer told me it's my property, although he recommended I have the work done. Can I be forced to allow these people in to do the work?
