HVAC reviews in Denver, Colorado

Mario and his dad were great. They've done two jobs for us and are thorough and fair.

This company was great he quoted me a time he was going to show up and was more than prompt. He showed me the problems and quoted a fair price and followed through and fixed them all.

Even though busy, they have made time for us, gave an affordable price, came back after hours later on .wonderfully caring and honest. They take time explaining how things work, why they work, and were able to come up with a solution for our particular situation, where as another company did not.

This family-owned business is unlike any other business I have worked with in a long time. They are skilled, knowledgable, honest and really care about their work. They took the time to educate me and helped me look at long-term solutions/care of my HVAC system. Additionally, they went above and beyond in correcting other issues unrelated to the work they were contracted to do. (Eeeek? Things that need to be addressed). The craftsmanship is clean, thoughtful and tidy. Perfectionistic and impeccable.

Replaced my HVAC system in a quick timely manner and it didn't break the bank. Very friendly, courteous, and very responsive. Would highly recommend them. Forget the big HVAC companies out there and go with them.

Steven and sons do amazing work!! They were very punctual and did a great job replacing my old furnace/ac system. Will recommend to all my family and friends.

Mariano was awesome! The communication was great and he fixed my heat in no time. Highly recommend this company.

Just FANTASTIC. Mariano and I had a great first phone call, chatting details for about 10 minutes, then we hammered out the details via text over the next couple days. No hard sales pitch here! Mariano talked to me about different system options, pros & cons, brands, every detail I asked about. He shared his expert opinion and together we came up with a system with better equipment and a better cost.

I am SO HAPPY with how it all came together. I'm glad we didn't go with the first quote we got.

Steven, his sons, and their helpers are a great team.

I had some parts replaced this month on my 15 year old furnace-the tech person Mariano explained what needed to done, did quality work, and at a very affordable price. I have peace of mind that the work was done right and am well pleased with this company.

The team was friendly, quick to respond and knowledgeable. They outfitted our home with a brand new furnace and AC system. They stand behind their work which is something I really appreciate and they didn't leave until the job was done and we were completely satisfied.

I had Steven & Sons Change out my heating system before the winter 🥶 never been so warm and cozy in this house.

Very respectful and responsive. Would definitely recommend!

This a geniune family business that cares about the job they do and the customers they serve! They are friendly and communicate with you when they are on the way and during the job! Steven & Sons put my mind at ease knowing all is well with my heating and AC! And assured me to feel free to call them with any problems that may arise! Their pricing was reasonable and their work is unbeatable! I promise you won’t regret hiring Steven & Sons! Five Star all the way around!

Steven and Mariano replaced our furnace and entire A/C system. They did a fantastic job! Gave me a superb deal, kept me informed the entire process and everything now works perfectly. Extremely professional, courteous and knowledgeable. We will be using them again!

True professionals of their craft. Mario and Steven were great letting us know exactly what they were doing with our furnaces, and they didn't make me feel rushed to make a decision either. Their prices were very competitive and we I be using them again in the future!

Steven and Mario did a great job installing my new furnace and heat pump system, as well as a whole house humidifier. They were knowledgeable and explained thoroughly how my new system works. I felt very comfortable with them in my house and even left to do a few errands while they were here. They were super friendly to my two dogs as well! I highly recommend Steven & Sons!

They were quick and knowledgeable when I was having some problems with my heating system. Mariano got me back online after a run to the supply house. Fair price and would have no problem referring Steven & sons.

GREAT service! After installing a new AC & furnace for us last summer, the AC went out this June. I texted late at night and they showed up first-thing the next morning. Got it fixed within an hour - just a bad capacitor.

I hired Steven and Sons for my AC replacement for my condo this summer. During this time, I asked a lot of technical questions before making a final decision on the overall project. My project was a bit complicated because of the design of the original AC unit at my condo. Mariano who co-owns the company with his father was very patient and very detailed in all the responses he provided to my questions. He also gave me the confidence that the job would get with the highest quality of workmanship which I witnessed myself while they performed the work. It's not easy to find a great, fair, and communicative AC company in Colorado and I feel I have finally found someone who I can trust. I called Steven and Sons back to my condo to clean out my HVAC ducts because I was so happy with their work. I highly recommend them to anyone for their Heating and Cooling needs.

Mariano came out on short notice and resolved our issue. He is extremely knowledgeable and made suggestions on how we could improve our system. We are a recuring client and highly recommend Steven & Sons for any HVAC issues!

When our 27 year old HVAC system went out, we got quotes from a couple companies. Mariano was responsive and friendly via text. We felt good about the equipment suggested, price, and installation timelines. When install day came (the following Monday), the whole team showed up - they were on time, friendly, and careful with our home. They ran into a couple bumps with our existing thermostat and other equipment, all of which they were cheerful about getting taken care of (they called tech support for our thermostat and brought in wire splitting parts as needed).

We reported that the new AC unit sounded like it was starting hard and they came back out a few days later to find that the Honeywell tech support person they worked with on day 1 gave them incorrect instructions. They fixed it up and now all is working great. They were even conscious about putting our vining plant over the thermostat (which it wasn't long enough to do when they started the process a few days earlier).

We're thrilled with their competence, competitive pricing, attention to detail, and friendly demeanors. Highly recommend!

Mariano came through big time. Did a great job , efficient, honest. Hard working. I would definitely highly recommend this company!
