Our Four Seasons sunroom was installed by a franchisee in Paramus, NJ. We did not experience any issues with the installation of our sunroom and it has held up well, however it is very inefficient from a heating and cooling point of view.
In the summer it gets hot and in the winter it's too cold. Heating and cooling it to the same temperature as the rest of the house would be too expensive.
I'm now having a ductless mini split heat pump and AC unit installed to supplement the heating and AC in the room. In hindsight I should have gone with traditional construction.
