We're a local, family-owned and operated Denver HVAC company that installs, repairs, cleans, and certifies furnaces, air conditioners, boilers, water heaters, and gas fireplaces — for homes and businesses across 23 cities in the metro.
MileHi HVAC is a family-run shop based at 4885 S Broadway in Englewood. We install, repair, clean, and certify the systems that keep Denver homes and businesses comfortable — furnaces, air conditioners, boilers, water heaters, gas fireplaces, and the rooftop units that sit on top of the city's restaurants and warehouses.
We work the way a small shop should. The phone gets picked up. A tech actually comes out and listens to the noise your AC is making before quoting a number. Estimates are free. Pricing is upfront and honest — no surprise charges, no add-ons that weren't on the original quote. When a job's beyond what we can do that day, we'll tell you where to go next.
Most days, that approach is the whole pitch. Seniors and veterans get 5% off. Realtors get pre-listing certifications that help homes sell faster. And every customer — first-time or fifteenth-time — gets the same crew that the last five-star review described.
When the heat goes out in January, you don't have three days. We work to get a tech on-site the same day whenever the schedule allows.
Before any work begins. You see the number, the scope, and the parts — then decide.
Upfront and honest. No hidden charges, no surprises on the invoice. The number you're quoted is the number you pay.
Our installers take real pride in the finished work. Drop cloths down, debris hauled out, walked through before we leave.
You'll see the same names on your estimate, your install, and your follow-up call. That's not by accident — it's a small shop on purpose.
Runs the shop and answers the buck-stops-here questions. Reach him directly at geno@milehihvac.com.
The name customers ask for by the second visit. Furnace installs, AC repairs, rooftop commercial work — and the guy walking you through how your new system actually works before he leaves.
Works the install side with Steven. Customers consistently call out his work as thorough, clean, and professional in their reviews.
The first call. Walks you through your options, prices the job honestly, and makes sure you understand the scope before any wrench is turned.
Keeps the day moving. If you've called in about a window or rescheduled around a busy weekend, you've talked to Joni.
Quick with answers, gets you the paperwork, and makes the back-office part of the job feel as easy as the work itself.
"We had a great experience with the whole team. Shaun was so helpful with answering all of my questions and provided affordable estimates. Steven and Angel did great work on the install and clearly take great pride in their work, and they did a lot of work! They left the space they worked in cleaner than it was when they arrived! Neymi was also very helpful and quick to get answers. It was a pleasure doing business with MilHi HVAC."
"Steven and his apprentice Angel were awesome! We are new business owners of a restaurant and our a/c went out over a busy and hot weekend. They were able to come out first thing Monday morning to diagnose and repair our air conditioner. This is a commercial unit on top of our roof, so not an easy task. They were fantastic about educating me on the system. They gave our machine the love it needed to be functional again right away. Great guys, we would definitely use them again if another issue comes up!"
"Huge shoutout to the MileHi team that I worked with including Joni, Shaun, Steven and Angel. They answered all my questions from start to finish and made the entire process easy. The furnace install that Steven and Angel did was thorough, super clean, and professional. Highly recommend!"
