Jim Sanders and Dan Johnson started this company nearly five decades ago with one rule: honest work for honest prices. The trucks have changed, the equipment has changed, the team has grown — that rule hasn't.
When Jim Sanders and Dan Johnson started Sanders & Johnson back in 1977, Denver was a different place. Their plan was simple: do the work themselves, charge a fair price, and treat every customer the way they'd want their own family treated.
Nearly five decades later, the company has grown well beyond two guys and a truck — but the operating manual hasn't changed. Every job still goes out under the standard Jim and Dan set on day one.
Jim Sanders and Dan Johnson open the doors with two trucks and one promise: honest work for honest prices.
Through Denver's coldest winters and hottest summers, we've been the call homeowners make when it matters.
Our technicians have worked in homes of virtually any age or condition, from 1890s Victorians to brand-new builds.
From Denver and Aurora out to Evergreen, Breckenridge, and the mountain towns — if you're in the metro, we cover you.
Jim is the "Sanders" half of the partnership that opened this company in 1977. He's still the name customers reach for when they want to talk to someone who'll handle their home like it's his own — and he still comes out on calls when the moment calls for it.
Dan is the "Johnson" half — and the reason the company's standard for installation quality is what it is. He believes that how a unit gets installed matters far more than which logo is on the side, and he's trained every generation of crew that's come through the door on exactly that.
These aren't slogans on a wall. They're the rules that decide who we hire, how we price, and what shows up at your door.
No upselling, no gimmicks, no surprises at the end. Over 90% of our prices come in similar to or better than local competitors — we welcome the comparison.
We're a team of local, community-minded people. We treat you like a neighbor instead of a sale — because most of our customers stay with us for decades, not single jobs.
Calls are greeted by our in-house staff, not a call center. Same-day service is available for most emergencies — you rarely have to wait to get your problem under control.
The brand on the box matters less than the hands installing it. A properly installed mid-tier unit beats a sloppy top-tier install every time — and we won't ship work we wouldn't accept at our own homes.
Trent, Leo, Matt, Zabih, Tyler, Josh, Ian, Reza, Noah, Kobe — they show up in marked Sanders & Johnson trucks, in uniform, and they treat your home like it's theirs.
"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. They have earned our business for as long as we live in Colorado!"
"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."
"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!"
