"They were very punctual and clean and courteous and explained the installation. Worked very hard and got the job done with an excellent product. We installed 2 windows."

"Dave was great! The best communication and transparency I've seen in a long time. Dave explained what he needed to do to install the dryer vent and got right to work...NO wasted time. He installed the vent and made sure it was working properly. The vent looks great! Dave is knowledgable, professional, and a nice person. He also stayed in touch, letting me know how soon he would arrive and when he was on his way. I really appreciated that. We will definitely call him the next time we need a handyman."

"Jesse was great and did a nice job installing my new doors and hauling away the old ones. I would absolutely hire him again for small jobs around the house."

"Pat and Tom installed a 5 ton heating and AC unit in my garage/workshop, last summer, and now I can make saw dust 7/24 all week long. Their work was exceptional. Service after installation was done without question. Pat replaced a part in my electrical panel that was defective. Professionalism, installation was exactly what I needed, based upon the size of the garage/workshop area I work in. Service after installation was right on. I would highly recommend R&C heating and air, without question."

"They could not repair our old rusted out swamp cooler, but the installed a new one in a professional and timely manner."

"37 Legacy did an outstanding job on getting the floor inside my shed reinforced with stronger plywood. This has been a long time coming. Now I can put a small workout bench inside (along with padding of course) so I can work out at home vice go to Planet Fitness. Again, I recommend 37 Legacy for any handiwork needed!"

"If I could give six stars I would. This company is great! Fast, efficient, clean, friendly, customer service oriented, caring, accommodating, and just all around extremely pleasant. The installations are very clean. Thank you Vlad and Slavic for making our installation of a AC System as painless as possible. The entire team was outstanding!!"

"I had called another plumber who was a jerk and only gave me a recount of problems. When I called these guys they were there in a hour, and Robert Ibarra did a great job with a smile. He looked at my old Victorian house and found solutions to our problems, and then fixed the kitchen sink, and installed our tiny bathroom sink. We will be calling them in the future!"
