Our story

Quality service to our customers — that's the mission.

It's the line we wrote down at the start. It's the line that still runs the company today.

Ultimate Heating, Cooling, Plumbing & Electric opened its doors in 1999 and has remained family owned ever since. Through every season, every cold snap, every Denver heat wave, we've kept the same standard: do the work right, explain it honestly, and stand behind it.

With over forty years of combined experience in the HVAC industry, our NATE-certified technicians can diagnose, repair, maintain, or replace most makes and models of equipment — including Carrier, which we're proud to install as a Carrier Factory Authorized Dealer. That status isn't handed out. It's earned by meeting strict installation, training, and customer-satisfaction standards year after year.

We've grown a lot since 1999, but we've kept the things that mattered from day one — fully stocked trucks, friendly professionals, fully licensed and insured crews, and the promise that we're not happy until you're happy. Same-day service when we can. Complimentary second opinions when something doesn't feel right. A 100% satisfaction guarantee on every job.

Most of all, we've kept the part about treating you like a neighbor — because in Denver, that's exactly what you are.

What we stand for

Five things you'll notice on every job.

Honest, flat-rate pricing

No surprises. You'll only pay what you're quoted — never more. The number we tell you before we start is the number on the invoice when we leave.

Same-day service

When something's off in your home, you want it fixed quickly and done right the first time. Our trucks are fully stocked so we don't leave to come back tomorrow.

Complimentary second opinions

Got a quote from another company that feels off? We'll come out, take a look, and tell you what we'd actually do — no charge, no pressure.

100% satisfaction guarantee

We're not happy until you're happy. If something's not right, let us know and we'll make it right — that's the whole agreement.

Free in-home estimates

Thinking about a new system? We'll walk your home, measure, and write up an honest estimate. No cost, no pressure, just options.

Friendly, licensed pros

Every technician arrives in uniform, explains your options before any work begins, and treats your house like it's their grandmother's. Fully licensed. Fully insured.

In our customers' words

Twenty-five years of "they did a great job."

We let our work speak for itself — and these are the actual reviews customers have left this year.

★★★★★
"We have been using Ultimate Heating and Cooling for over 25 years and we highly recommend them with a rating of 5 stars. The Ultimate team arrived on time and went to work right away. All of the team were very knowledgeable and completed all of the demo and installation work in an excellent fashion within one day. My compliments to Junior for the creative copper artwork above the water heater."

"I recently had one of my furnaces go out and had called Ultimate to come out and give me a bid. They kept me in the loop on when they would be at my house, and from start to finish they did an excellent job. Took less than one day to replace both of them, and when they left you would never have known they were here. Everyone involved knew what they were doing, and were extremely professional."

"They did a great job of explaining my options for a new furnace. Everyone was professional and respectful. The cost was best of 3 bids and the most professional presented. I would recommend Ultimate."
