Customer Testimonial

Michael F.

Pawleys Island, SC

This homeowner from Maryland has been completing some home improvement jobs throughout their home. They decided to convert their garage into a second living space for when their family comes to visit, to include a new double sided fireplace. To insure the conversions comfort, the home owner had new blown in attic insulation installed, along with an insulated attic hatch. We also placed fiberglass wall batts before the sheetrock was completed. His video testimony was a treat because as a business owner himself, he was blown away by our appointment center. "Jill's kindness really did set the mode of our whole experience!"

I was very impressed with the quality of work on an overall basis. Also, I really like the fact that everyone I spoke to was very knowledgeable about products and services. I mostly spoke with the Comfort Adviser who was very helpful with the time frame to get the job done. Thanks for everything.

Mr. F.

North Carolina, NC

Along with your quote, I received three others. You were, by far, the best overall proposal. Additionally, dealing with your Comfort Adviser was a very good experience. With all the other quotes, I felt pressure to make a decision quickly and they immediately told me that certain systems would meet the tax credit criteria. Your Salesperson was very patient and instructed me that it would be best to consult a tax professional regarding the credit. This further eased my mind that I was making the right decision.
You helped us also to get rebates from the manufacturer and the power company. Great job! Read Full Testimonial
