The people from Energy Attic were really prompt and the service was good. One of the owners actually came out and fixed a minor issue we had after the work was done. The guy who hooked us all up originally actually left the company, so the owner did a follow-up to make sure everything was taken care of and he did a house-call to fix the issue we had. The owners are really supportive and truly believe in their mission. They'll follow up with you even if you have an issue with the sales-person you're dealing with, so you know there's always someone else in the background double-checking that everything is OK.
