We had our old insulation removed, new insulation blown in, baffles put in across the entire front of our home and vents on the back. This was a big job because our attic had so much debris that had to be removed along with the old insulation. Ed from Addict Insulation did an excellent job. The removal took longer than he had planned but the job was completed without any additional expense. I would definitely recommend him.

Duct Insulation
If the ducts in your home are in unconditioned space, seal and insulate them. If you’re building a new house, place ducts in the conditioned space to avoid the energy losses associated with most duct systems.

Homeowners, are you noticing that your AC isn't keeping every room as cool as you'd like?
Uneven temperatures and overworked air conditioners often point to poor insulation. Gaps in your attic, walls, or around windows can let precious cool air escape and allow unwanted heat to creep in, forcing your AC to work harder for less comfort.
Upgrading your insulation and sealing leaks can help maintain a consistently cool home and reduce energy bills.

I was very happy with the service.We had a pest control company stop by and inspect our attic, and it was clear they lacked expertise and were playing pricing gamesWe had Addict Insulation out for a second opinion, and it was the opposite experience. The expertise was clear from the first conversation, and the pricing was straightforward, honest, and much lower than Moxie's first quote. We scheduled right then and there, and I'm glad we didAfter the service, we noticed our house smelled better, and our A/C was running less often. Would 100% recommend!
