"We had S&J install a new mini-split ductless system on a floor that we couldn't get cool. We also had them analyze our current system in our townhouse, which required an upgraded cold air return duct due to a bad design by the builders. Mitch was our representative, and he did a fantastic job analyzing what we needed. Mitch provided a better, more effective solution than we had heard from any of the other vendors. Additionally, he got us a great price (after rebates) on a system that was better than the other systems we had been previously quoted. The mini-split installation was a challenge, but the installers did a great job. They took their time to create an installation that looks and operates great! The cold air return duct upgrade brought our system static pressure from 0.75 inH2O down to 0.5 inH2O total, which is nearly perfect. Our air handler is running quieter now, and we are getting more airflow through our system. I would give Sanders & Johnson 10 stars if I could!"

"Terrible experience. I had hired Mike multiple times previously and had great outcomes. Then, I wanted to replace plumbing in half of my home. He send his employee, who was a total nightmare! Screaming profanities in my home, never working, my husband ended up asking Shawn to leave. One of Bathrooms needed to be redone, because Shawn did all the work incorrectly. Mike had the nerve to tell me "he was losing money this job." Well, Mike never checked the other areas Shawn had finished. I had to redo my kitchen plumbing 5 years and ago. I also have had to replace my shower tile due to the incompetence of this company. No apologies, or accountability for the disaster. Only gaslightling, pretending to be a victim, and blaming his employee. Hire at your own risk!"
