Jim Sanders and Dan Johnson started this company in 1977 on a simple idea: do the job right, charge a fair price, and treat people like neighbors. Decades later, that's still how we run it.
Our techs are NATE-certified with over 100 years of combined experience across homes of virtually any age or condition. No upselling, no gimmicks, no surprises at the end of the invoice.
"Highly recommend Sanders & Johnson! Over the years since we bought our home, we've tried many HVAC companies and finally found S&J. They are super professionals. If you have an emergency, they get someone out same day. If it's preventative maintenance, they're efficient and thorough. Prices are fair."
"Good price, excellent service and professional attitude. They replaced ~110' of sewer line in one day in poor weather conditions. Followed up with inspection and relocated line to prevent from having to remove any trees. The tech Zabih kept me informed. The crew was courteous and had minimal interruptions to the sewer access. Highly recommend this company."
"Saunders and Johnson has been amazing. Tyler came by to help determine where my tankless was leaking and nothing turned up the first time. When it started to leak again, they waved the fee. Tyler was diligent and found the origin of the issue. He talked me through retracing where the water was coming from with a camera, provided me with a detailed report and several options for repair vs replace. Everything was high quality and I'd recommend them to anyone."
"We appreciate Zabih for his help plumbing in a new shower valve and replacing our old fixtures. He has a gentle nature, communicates clearly and performs excellent prompt service. We would definitely recommend him."
"Sanders & Johnson have been our go to for all HVAC and plumbing. They are always on time and very professional. Any items needing attention are explained in detail and repair pricing is totally transparent. Noah and Kobe replaced our hot water heater on a day's notice after it stopped warming properly. They were super nice and got the job done quickly and cleanly!"
