Growing up, I was raised by a single mom who worked hard to give us the best life she could. She taught me a lot of things, but one lesson has always stuck with me: “If you're going to do something, do it with excellence, or don't do it at all.”
That lesson shaped who I am as a man, a father, and a business owner.
When I started this company, I knew I wanted to build something different. Not just another heating and air conditioning company, but a company built on genuine care for people.
I often think about my mom when it comes to how we serve our customers. I think about someone showing up at her home to fix her furnace or air conditioner. Would they be honest with her? Would they take the time to explain things? Would they look at the big picture, not just the problem in front of them? Would they treat her home with respect?
That's the standard I hold our company to.
I want every customer to receive the same honesty, patience, respect, and quality of workmanship that I would expect someone to give my own mother.
Because at the end of the day, we're not just working on heating and cooling systems. We're taking care of people, their families, and the place they call home.
My promise to you is simple: We'll always strive to do what's right, even when it's not the easiest thing to do.
Thank you for trusting us with your home and giving us the opportunity to serve your family.

Honest feedback that drives us forward
Upgraded an old AC unit to a heat pump. The owner is great to work with on planning a new system, and Lukas and Tristan did an outstanding job on the install. Glad I found these guys after working with some bigger companies that would send techs who didn't know what they were doing and charge a fortune.
Tristen was knowledgable and courteous. The installation of the Aprilaire 800 whole house humidifier was done exactly as expected. I’ll definitely be a repeat customer.
Excellent in every way! He was thorough and explained everything and we were given a very fair price for what was done. Highly recommended!

"100 STARS IF I COULD If you’ve ever dealt with HVAC companies, you know it can be hit or miss. Michael from Flatirons Heating and Air is one of those rare guys where you immediately realize—you made the right call. Best way I can describe it (if you've seen The Patriot): if Benjamin Martin ran an HVAC company, it would probably look a lot like this. Michael showed up early—actually early, not “sometime in the window.” He came in ready to work, got right to it, and didn’t waste a second. The whole time he had this calm, dialed-in focus like he already knew he was going to handle whatever came up—like he’d already planned the battle before he even knocked on the door. He went through my entire system top to bottom and didn’t skip a thing. Every component got attention. If there was something even slightly off, Michael found it—no mercy. Hidden issues didn’t stand a chance. The level of detail was honestly impressive—he did not miss. It felt less like a service call and more like a full sweep for anything trying to cause problems later. What stands out is how sharp he is. You can tell right away Michael really knows his stuff. Everything he pointed out and explained was clear, straightforward, and made total sense. No fluff, no confusion—just someone who understands his craft inside and out. He explained it at a level where I could actually understand it (I know nothing about HVAC), which is saying a lot. And just as important—he’s honest. No upselling, no pressure, no trying to turn a simple job into something bigger. It felt like he was looking out for me and my home, not just trying to run up a bill. Like he’s there to protect the house, not take from it. That kind of trust is hard to find. On top of that, Michael’s just a solid guy. Easy to talk to, respectful, and professional without being stiff or robotic. You don’t feel like you’ve got some random technician in your house—you feel like you’ve got someone competent who actually cares about doing things right. It honestly felt like I had a friend in my house who just happens to be really, really good at HVAC. By the time he wrapped up, everything was dialed in and running the way it should. You can tell he takes pride in doing a thorough job, not just getting in and out. No loose ends, no shortcuts—just everything handled. If you want someone who shows up ready, knows exactly what he’s doing, and treats your home with respect, Michael at Flatirons Heating and Air is the guy. I’ll absolutely be using him again. Honestly, if Benjamin Martin had traded the tomahawk for gauges and ductwork, his name would probably be Michael."
