HVAC reviews in Denver, Colorado

Great from start to finish. Marc came out a few times and really worked on a system that fit our needs. Never tried to over sale us. The install crew were first class. Cleaned up everything, put down tarps to protect the floors. Just good people that work there.

These guys are great. Arrived on time, were very friendly and the price was very fair. I felt like they really care about delivering great service and making sure we didn't have to do more than what was necessary to make sure our HVAC was working perfectly.

Dalco installed a new furnace and air conditioner for me in December 2024. I can't say enough good about the installation. They were right on time, considerate, knowledgeable and very professional.
I would highly recommend this company and will certainly use them on any future HVAC needs.

Serviceman was prompt to the appointment and in short order was able to isolate the problem and provide maintenance to get the system up and running again.

We scheduled an initial service with Matt and he came out within a couple of days, which was great. He was friendly and easy to work with. Unfortunately, we had a glitch happen after Matt left. Matt followed up with us personally and was extremely caring in resolving the issue. He is personable and an honest man, which is not always easy to find in business these days. The next time we have a need, Matt will be the first person we call.

Maintenance provided by Jorge to our furnace and water heater was professional and fast. He even arrived early!

Jorge arrived on time. Services preformed throughly and promptly. Diagnosed and performed necessary repairs to AC unit. From setting up next day appointment to completion everything was done professionally. Glad I called Dalco. .

We are very satisfied with the installation of a heat pump/air conditioner , furnace and water heater. They were very professional and able to get it done within 2 days.

I couldn’t be happier with the service from Matt and his team at DALCO! They installed a new AC system at my home, and the whole experience was excellent. From the initial consultation to the final install, the team was professional, knowledgeable, and courteous. They helped me choose the right unit for my home, showed up right on schedule, and completed the job efficiently with great attention to detail. The new system is running perfectly and keeping the house cool and comfortable. Highly recommend them for anyone needing HVAC work—top-notch service all around!

We had a great experience with DALCO HVAC company. The owner and the scheduling manager truly came through for us when an issue came up, and we are very grateful for their effort and support. The technician did a very thorough job and was extremely professional and knowledgeable, making sure everything was done properly. Overall, the quality of work and professionalism really stood out. We highly recommend them and truly appreciate all they did for us.

I think it's cool that i received an email and a text before Earl, the technician from Climate Masters HVAC Service, showed up. They even included a picture of Earl which was a nice touch to ensure i knew who was coming to look at our ac unit. Earl was gentle, patient, and took the time to listen to my concerns, while thoroughly inspecting our ac unit. He managed to solve the problem with our ac unit and now we can finally enjoy some cool air instead of the hot we were dealing with. I am very grateful for him. I also had a good experience with their call center. The representative was really helpful and worked to arrange the soonest possible appointment for me. I think it's important to support local businesses like this one. I will definitely reach out to them for any future ac issues we might have in Denver!

I've been a long-time customer of Climate Masters HVAC Service, having been with them for 27 years. Just recently, I had two outdated (Freon) Carrier heating A/C systems replaced with modern (Puron) Carrier units. Though the old systems were operational, I decided to upgrade since Freon is gradually being phased out. Earl was the one who gave me the quote, assuring that the new units would be the right size to effectively handle both heating and cooling tasks. The installation process was carried out by skilled technicians including Nolan and Landon. They were knowledgeable, punctual, friendly, and made sure to keep my home clean during the whole process. One of the systems that needed replacing was in an attic with very limited space for working. Despite the challenging and tough working conditions, they successfully removed the old system and installed the new one. Exceptional work!

landon and the team from climate masters hvac service replaced all the ductwork in my crawlspace, and did a fantastic job! even though the work took a bit longer than planned, they stayed until everything was finished and made sure i was completely happy. they really focused on my satisfaction and did a very thorough job. i highly recommend them for any ac repair or hvac services. they are trustworthy too—i had to be away at work one day while they needed access to my house, and i had no worries about anything being damaged or missing. the crew is reliable, responsible, and truly cares about their customers. i'm definitely going to use their services from now on. their pricing was also very fair. i compared a couple of quotes for the same repair, and they gave me the best deal and the most detailed work.

we had a mini-split heating/ac unit installed for our porch and we couldn't be more satisfied with the entire process. the sales representative was attentive to our needs, didn't push us towards anything we didn't want, and took the time to answer all our questions. with our limited space, the installation was a bit challenging, and we had received conflicting information from other contractors. however, the installation went as planned—no delays or unexpected issues—and the team at our home was friendly, approachable, and very professional.

Jamie and Earl are absolutely fantastic to work with! We were incredibly fortunate to connect with them. In just a few hours after my call, Jamie was at our doorstep in Denver, evaluating our HVAC issues and promptly providing a reasonable and firm quote. There were no hidden costs or unnecessary upgrades, he was straightforward about what our system needed. Within two business days, Jamie and Earl had arrived at our location, carried out their job efficiently and professionally. They cleaned up post-service and took us through a final walkthrough, explaining what they had done and how to maintain our HVAC system. I would strongly advise anyone who needs HVAC services to consider this team. They are a local business that truly gets things done the right way!

Last week, Jamie from Climate Masters HVAC Service gave me an estimate for a new AC unit, breaking down the cost and warranty details clearly. This morning, Nolan and Earl came to install it, demonstrating great professionalism as they explained every step of the installation process. Earl later took the time to explain in depth about the maintenance of the AC system. I highly recommend them for AC unit installation services in Denver. They did an outstanding job!

I've been relying on Climate Masters HVAC Service for the past eight years to service my ac system, and i can't recommend them enough. When it was time for a new furnace and central air unit, they were the ones I turned to instead of Four Seasons. Their team, including nolan and earl, are highly professional and always do top-notch work. Remember to reach out early, as they are often in high demand when it comes to working on your furnace in Denver. Trust me, they are worth the wait!

My brand new AC unit and heat pump were installed in just a single day by Climate Masters HVAC Service. I'm quite amazed and eagerly anticipating the comfort this system will bring for countless years ahead. The workers, Jamie, Earl, and Nolan, were fast and efficient in removing the old AC unit. They installed the new outdoor converter and indoor equipment in no time. The only minor delay was due to my outdated electrical panel needing a specific breaker. Once it arrived, the system was promptly connected and my house started cooling instantly. My tenants are ecstatic! Thank you once again.

During my home renovation, Landon installed a new furnace system. I have nothing but praise for them and I'm completely satisfied with their work. Nolan was incredibly patient with my countless inquiries and numerous design modifications. He even made multiple visits to my home to discuss various options. The entire team was professional and demonstrated a high level of expertise. The furnace repair technicians, including Earl, arrived promptly, displayed a great deal of politeness, and took extra care during the installation. They also showed me how to operate the new system. Even my highly meticulous contractor was impressed with their work!

had a great experience with our ac repair and installation. they put in two new ac units at our house in denver. the prices were very fair compared to other quotes we received. landon and the team did an awesome job and their work was impressively neat and tidy. they moved two returns and added vents, and you can’t even tell where the old ones were. i was expecting a lot of mess and dust, but when i got home, everything was clean. any dust from the installation was cleaned up before they left. the workers really put in the effort and were very respectful. the price was right, communication was clear, and the job was finished quickly and professionally. overall, it was a great experience and i would recommend them to anyone needing ac repair or installation!

i had a fantastic experience with climate masters hvac service! landon came out to my home in denver and quickly figured out what another technician couldn’t solve after spending hours on my furnace and air conditioner. the other company’s technician had told me i needed to replace both my furnace and ac, even though my air conditioner had been working perfectly until he looked at it and it suddenly stopped. landon arrived to give me a second opinion on my furnace and ac. in just a few minutes, he discovered the issue with the air conditioner (it had shorted out) and got it running again at no charge! he also advised that replacing the air conditioner wasn’t necessary, and it’s still working great years later. they replaced my furnace with a better price than what i was originally quoted, and i’ve been very happy with both their service and the new furnace. they really know their stuff when it comes to hvac systems. i’ve recommended them to friends and would definitely use them again!
