HVAC reviews in Denver, Colorado

I needed my air ducts cleaned after suffering from bad allergies. Apex Clean Air came through and sent their technician Mike to perform a thorough inspection and sanitize my ducts and thoroughly clean my HVAC system. Mike was excellent in the customer service he provided and in representing the company. My furnace was in need of a good cleaning and Mike explained everything in detail from start to finish. I now have fresh air circulating through my ducts and my families allergies have also improved. I highly recommend Apex Clean Air because of their integrity! A very honest business and reasonable in their pricing. This company will go above and beyond to ensure you are satisfied!

Ken was on time and went immediately to work cleaning the dryer duct. He was friendly, knowledgeable, and did a great job. The process was quick and done in such a way that it did not make a big mess. Based on my experience, I would recommend Apex!

If we could give a 10 STAR REVIEW to the 6 young men that Apex sent to install our new HVAC units & large diameter ductwork, without any hesitation, We Would! They showed up on time, were very personable, answered all of our questions & concerns, worked together hard & seamlessly for 2 full days, did impeccable cleanup & they all stayed until the job was complete! Michael, Alexis, Will, Isaiah, Diego and Angel. The WOW install team! After this experience we fully trust Apex to take care of us in the future. And we can truly, highly recommend Apex to anyone with HVAC replacement needs. 🙂

Ken did an outstanding job servicing my homes air duct system! He was very knowledgeable, professional, friendly and communicative! Left the home in great condition cleaning up after any mess or dust! From setting the appointment to the day of service, the team’s communication as top notch. Thank you Ken for great service today. Highly recommend Apex Cleaning!

I had a rental property needed deep cleaning and service a week before Christmas and I reside out of state. I called apex customer service let them know what is going on what my budget is they came out and helped with vent cleaning. Deep cleaning furnace dryer vent. So worth it . The mess was left by tenants and they removed everything

UPDATE:
Britny from customer service reached out and was very helpful and offered to send out one of their best guys to re-clean the ducts. Frank came out and did a much more thorough job. He pulled out multiple large items with his bare hands that had been missed by the first cleaning. He then proceeded to re-clean all ducts. I included a few more before and after photos that show how much was missed on the first cleaning that Frank was able to fix.

Original review: We used a Groupon for duct cleaning, and had to wait a month for our appointment, which was rescheduled the day before service was scheduled. We were able to be seen last minute, which we were (at the time) grateful for. When the technician arrived, he attempted to upsell us on a new air filter and a disinfecting spray. We declined and he got to work. Upon receiving our “after” photos, we could clearly see dirt, debris, and some larger items left in the vent (left by previous tenants), including an electrical faceplate, credit card, phone pop socket, and door stop. All items were easily removed by hand and shows some lines were not even attempted to be cleaned. We’re fortunate we only paid for a Groupon and not the full price, but even the little bit we spent on the Groupon was a waste of money.

Thrilled new client here. I was amazed at how swiftly Santiago could arrive and diagnose the problem, fixing it in merely a few hours. The service has left me feeling ecstatic and now my family and I can luxuriate in a cool home in Denver. Thanks Santiago!

every individual from harmony heating & air conditioning that arrived at my denver property and responded to my calls was exceptional: they were supportive, skilled, considerate of kid nap times, polite to me, informed, punctual, and friendly. Plus, they managed to work within my budget, ensuring we got the best value for our money. they didn't attempt to upsell or intimidate us into getting things we didn't require. blake, jerome and walter have been especially helpful. for any ac repair needs, we will always reach out to them.

I've utilized their services before and have always been satisfied. This time, there was a minor miscommunication, as I wasn't aware that they wouldn't arrive if I was unable to answer the phone call alerting me of their arrival. However, when I managed to contact the office, they were excellent in accommodating me and arranging for a technician to come over soon, fitting into my schedule, even though the initial appointment didn't take place due to my mistake. The AC repairman who arrived, Jerome, is always indispensable and more than happy to clarify any uncertainties. He does an outstanding job with AC repairs. I plan to continue utilizing their services, but will ensure that I'm reachable by phone prior to the next appointment.

Blake, the AC repair expert, was timely, skilled, and friendly. He clearly communicated the issue with my air conditioning system and quickly resolved it. Now, just as Denver's weather hits its peak heat, my AC system is running smoothly. I would definitely use their services again and recommend them to others.

Outstanding service! Frank did an exceptional job and was incredibly well-versed in HVAC systems. We're very pleased with the AC repair service we received from Harmony Heating & Air Conditioning. Our air conditioning system in Denver is functioning flawlessly! We couldn't have chosen a more proficient company. We highly recommend them.

I've been a loyal client for a considerable amount of time, entrusting them with the annual maintenance of my two HVAC systems. They offer an excellent membership program, which I find quite beneficial. Curtis, the technician, demonstrated extreme professionalism and efficiency. With his extensive knowledge, he took the time to thoroughly explain the services he was performing and the additional options available. I'm truly satisfied with the service in Denver. Many thanks!

Great service! Curtis and the Harmony Heating & Air Conditioning crew were detailed, respectful, and considerate; my new air conditioning system is functioning perfectly, they tidied up post-repair so I didn't have to lift a finger; they even pointed out a hazardous gas leakage in the basement to me. Curtis ensured that i understood how the new AC unit operates, and double-checked to make sure nothing was left out. I'd give them more than two thumbs up if I could. Thanks, guys!

We collaborated with Walter from a reputable heater repair service for the installation of our Heating/AC system. We chose MiniSplits for our individual rooms and a Slim Duct for the shared spaces. The system has been functioning flawlessly, keeping us warm all winter. Their team was punctual, arriving early in the morning, eager to start. It took them a solid two days to manage our power requirements, set up the system, and even install a suitable attic entry door. We were particularly impressed that they employed a certified electrician to manage the power needs of the system. The professionalism was exceptional, and we are extremely satisfied with the outcome!

I recently got a full-building AC system set up in Denver by a renowned HVAC repair service, and the interaction with each team member was exceptional. Curtis, Blake, and Easton were polite, skillful, timely, knowledgeable, and efficient. I can confidently and without hesitation endorse them. I also scheduled a follow-up appointment to inspect my AC system, and the work done was professional, swift, and thoughtful. Their service truly left me impressed.

curtis from harmony heating & air conditioning was very professional and provided answers to all my queries. they successfully rectified a poor repair job done under my home insurance warranty and got our smart thermostat back up and running. curtis even suggested multiple solutions to the problem (initially, a control board was missing several terminal blocks when we purchased our denver home). i insisted on the most appropriate repair, so they promptly ordered the correct part from the manufacturer. this ensured we didn't lose the functionality of our ac/heater while waiting for the rest of the repairs. i would suggest their services to any homeowner seeking a better understanding of their home systems.

My heating system malfunctioned unexpectedly early on a Saturday morning. I reached out for help, and was provided with useful advice on how to keep the house sufficiently heated until a service technician could arrive. Within a short span of 2 1/2 hours, Isaac was at my doorstep. He diagnosed the issue and swiftly got the heating system temporarily operational again, until the necessary control board could be sourced for replacement. Just three days later, Isaac returned and installed the new control board, providing a lasting solution to the issue. This was my first experience with their HVAC services and I was thoroughly impressed. The team was courteous, supportive, and highly proficient in their work. The pricing was fair and they even extended a discount coupon, further reducing my expenditure. Despite my heating system being 22 years old, there was no attempt to coerce me into purchasing a new one. As a parent to a 10-year-old, the prospect of spending a weekend without heat was daunting. But the HVAC team promptly came to our rescue. For any future heating or cooling system needs, I will definitely be relying on their services and I strongly recommend them to others.

Curtis from Harmony Heating & Air Conditioning was extremely professional, providing a detailed explanation of the AC repair project. He captured photographs and videos of the proposed work, and patiently made sure I comprehended why certain components needed to be replaced. He even pointed out the specific parts that required replacement. Throughout the entire process, Curtis maintained a tidy workspace by utilizing protective gear. He was considerate enough to inquire if I had any queries or feedback about the work done. Curtis ensured to collect all the necessary details for the upcoming job, including the best time to contact and a follow-up date. He also made sure I was in agreement with a follow-up call concerning the recommended AC repair service. Overall, my encounter with Harmony Heating & Air Conditioning in Denver was highly satisfactory.

Frank and Curtis are among the most courteous and proficient individuals I've ever had the fortune to encounter and collaborate with. Both of these gentlemen went above and beyond to ensure I was well cared for. They were flexible with scheduling, managing to accommodate me sooner than expected. Curtis identified and addressed several issues with my AC system that I wasn't even aware of during his visit. He took the extra effort to educate me on the intricacies of my AC unit, explaining what was wrong, and also gave me a thorough understanding of my home's ducting system. He patiently answered all of my questions and allowed me to observe his work. I would highly recommend their AC repair services to one and all. A perfect 10/10 experience in Denver.
