We had 18 solar panels installed by Quality First Home Improvement, and our PG&E bill has reduced by $200! My brother is so impressed with our savings, that he's considering purchasing a solar system for his home. We also had Quality First replace all of our windows, and the comfort of our home has changed immensely. Our neighbor has 3 chihuahua's that bark constantly, and a rooster, but now we barely hear them. Both Kevin and Nathan, from Quality First were such gentlemen, and wonderful to work with! Thanks for providing excellent customer service!
