Smelled a slight gas leak and repairman Ivan Medina performed leak search on gas line connected and discovered leak at the flare on flex line. He replaced flex gas line and rechecked for gas leak. No gas was detected after replacing line. Repaired under warranty so no charge. Many Thanks, James ( a very satisfied customer).

Had a tremendous experience with RS Andrews and Keyshawn J. We had another company out to check a problem after a leak and they reported back "nothing wrong except your system is old and needs a replacement". Then 24 hours later the system stopped working. Called RS Andrews...they sent Keyshawn the same day...then he proceeded to not only diagnose & fix the problem, but assured us our unit still has a little life left. AND RS Andrews didn't even charge us for the visit because they have a "free second opinion" policy. Will definitely be contacting RS Andrews when it's time for a new system. Appreciate the great service and Keyshawn was helpful, polite, explained everything in detail & earned our trust.

RS Andrews sent their HVAC Technician Jonathan Balom who did an amazing job of serving our A/C unit that was blowing hot air on short notice. He replaced the worn out capacitor with a new one, so we didn't have to replace our old A/C unit. RS Andrews is a trustworthy company that I would recommend for Heating, Cooling, Plumbing and Electrical issues. Thank God I heard about these guys from the radio ads because what they say delivering smiles is true. They definitely delivered a smile for us.

RS Andrews has surpassed all my expectations for quality work, experienced team members, and prompt attention to my requests. Amber Magnus, my sales rep, was personable, efficient, and professional. She took the time to answer all my questions and to help me understand what work needed to be done to install a new HVAC and why. The installation crew was just as knowledgeable, personable, and worked together efficiently, with great attention to protecting my home. I commend this company for their focus on customer service. It is becoming more and more rare in today's environment.

Excellent! Jose was our technician and he was GREAT. Very personable, knowledgeable, and hardworking. It was clear he knew exactly what he was doing. His assistant, Justin, was also great. They replaced the booster fan and other piping in our laundry room. They left the laundry room very clean and then took time to answer our questions and review their work. Highly recommend.

Since the first day I contacted RS Andrews, the service has been top notch! From the attentiveness of the customer service person responding to the calls, to Thomas who came out for the repairs. Thomas was such a breath of fresh air! He was kind, knowledgeable, informative and did an absolutely amazing job identifying where the plumbing issue came from, to the actual repair. I was bracing for an astronomical price, but GOD!! Thank you RS Andrews for who you are and how you care for your customer base🙏🏽.

Paul Creel is a great representative of your company. Paul did a repair of the main water line coming into my residence. He explained the work process and provided me with an estimate. The work was completed in a timely and professional manner. I am very satisfied with the work and clean up of the area. I will recommend your company to friends and family. WT 8/14/2025

My home is 15months old. Built May 2024. I had issues with my air beginning June 2025. All maintenance was up to date. Called the original company that installed my HVAC system. 5 visits later still wasn’t fixed. They just kept “trying” things. My system froze again this time causing a water leak. Terrell T came out and asked questions and did adequate troubleshooting and within 30 minutes my air was cooling. He even followed up with me to make sure we were still good! Will definitely use them again.

Called out RS Andrews to get a plumber to diagnose my leaking Kitchen sink. Robert H came by and did an awesome job. He explained everything that was going on, was very knowledgeable, verified the water pressure at the PRV and recommended everything needed to get me back up and running. Thanks for the service!

I had a fantastic experience with Max Borrelli for the installation of my home EV charger. From the start, he was professional, punctual, and clearly knowledgeable. He walked me through the process, answered all my questions, and made sure everything was up to code. The installation was done efficiently, neatly, and with great attention to detail. It works perfectly, and I couldn’t be happier. Highly recommend to anyone needing electrical work, especially for EV setups!
