"We purchased a home with a renovation loan. Since I had hired Victor several times over the past couple years, he was my first choice for the project. We needed our kitchen installed, the laundry hook-ups and the popcorn ceiling covered up with bead board and trim and recessed lighting added. Victor is very easy to work with and communicate with. He is skilled and knowledgeable in every aspect of home renovations (electrical, plumbing, painting, carpentry, etc). We were extremely pleased with the work he completed and will hire him again for any and all future projects."

"Ray is very professional, and provided options for my air conditioning unit replacement. Ray went out of his way to replace a small gas line leak that he found. He also drove to Anaheim early on Saturday morning to pick up a part that was needed for the AC unit, and came over to install it so that I would have the air conditioner available for the upcoming heat wave this week. He and his team were on time, and considerate during the installation process. I highly recommend RS Air Conditioning & Heating."
