    On a particularly chilly day, our wireless thermostat unexpectedly lost all connection with our furnace. We reached out to a local HVAC company in the hopes that they could provide a quick solution. Within a short span of 2 hours, Clarence arrived at our doorstep. He took the time to understand our problem, ensuring he didn't leave until our furnace was back up and running. Clarence demonstrated a high level of expertise in heating and cooling systems and went above and beyond in explaining how we can optimize our system for efficiency. Alongside his professional abilities, Clarence also had a delightful sense of humor, making the entire experience enjoyable. We were thrilled to have him in our Westminster home. Many thanks to Clarence and his team.

    I arranged a service appointment for my AC unit with Harmony Heating & Cooling. Their specialist, Lucas, delivered outstanding and skilled customer service. I also had some questions about setting up a new air filtration system. Lucas took the time to address all my queries and even managed to install the new system on the same day! He's a pleasant and professional individual. This occurred in Westminster.

    UPDATE: Our whole building AC overhaul has been accomplished (even ahead of the scheduled time, I must mention). I am extremely satisfied with the service provided by Clarence, Lucas, and Kai from Harmony Heating & Cooling. They were professional, courteous, and fantastic, even in the face of challenges I presented them with (like clutter and a pet). I will definitely contact them in the future for any AC repair needs! Thanks again, team! Lucas also came out to provide an estimate on overhauling our AC system. He was professional and well-informed. He answered all my queries patiently and we are eagerly anticipating the completion of the service.

    I made a call one day, and the very next day, they were at my place ready to service my hvac system! Clarence and Lucas provided terrific, quick, and knowledgeable service. I decided to opt for their regular maintenance plan and I'm now more confident than ever that I have a trustworthy team to rely on if my heating system fails this winter in Westminster. Now, a year later, they've expertly repaired a different section of my 23-year-old boiler, helping me prepare for another winter. They're truly professional, respectful, and well-versed in the services they provide. I'd recommend them without a second thought.

    During the recent cold spell, my furnace suddenly stopped functioning. I reached out to Clarence, the owner of Harmony Heating & Cooling, who guided me through a diagnostic check of my furnace. As someone with mechanical experience, I attempted to rectify the issue but to no avail. Clarence personally came to my home in Westminster, identified several issues with my furnace, and suggested a replacement instead of costly, time-consuming repairs. His quote was significantly lower than any other furnace repair service I had consulted. Clarence is not only professional, thorough, and respectful, but he also takes time to explain the problems and physically shows the issues. He's a hands-on technician who does the work himself. It's not often that you find a company where you can interact with, negotiate a deal, and have the owner himself do the repairs. I strongly recommend that you have your furnace evaluated by Harmony Heating & Cooling before contracting with another service. You'll save money, receive quality parts and service, and have the opportunity to deal directly with the owner.

    I recently had a new furnace installed, along with an A/C unit featuring a variable speed fan, ultrasonic air cleaner, UV light for viruses, and a humidifier. It’s fantastic! My home feels much more comfortable, and my energy bills have decreased! The team was professional, prompt, and did an excellent job. Their quality of work and clean-up exceeded my expectations. I highly recommend their maintenance plan; it keeps the heating system in excellent condition. Trane is unbeatable! My previous Trane system lasted 20 years and was still running well when I had it replaced with a newer model. This upgrade has significantly enhanced our air quality and reduced our utility costs.

    As a new family in the area, it can be tough to know which company to reach out to for AC repair. Like many others, I searched for a business with positive reviews and came across Harmony Heating & Cooling. I'm so pleased I did! I called and scheduled an appointment with a friendly secretary, and they sent a technician right on time. I can't praise this company enough, especially the skilled repairman. He quickly identified the issue and had my AC running smoothly in no time. I really appreciate the excellent service; companies like this are becoming rare!

    I had a technician come out to service my older downstairs furnace recently. The initial worker wasn't able to fix the furnace after two visits, but he suggested contacting another service. The next technician arrived while the furnace was still running, looked it over, and shared his thoughts on what might be wrong. However, shortly after he left, the furnace stopped working. No problem, though! The tech returned and worked for over four hours, draining some water from clogged pipes. After he left again, the furnace ran for about 12 hours before it shut down once more. The technician said he would send a more experienced specialist. When the advanced technician came out, he quickly identified the problem as a clogged P-Trap, based on how long the furnace had been operating. He took care of the drain issue, and the furnace has been running perfectly ever since! The advanced tech also provided some useful maintenance tips. The total cost for everything was around $250, and they could have easily tried to sell us more services, but they didn't. After reading some other reviews, I was surprised because my experience was excellent. These professionals did a fantastic job!

    All I can say is wow. Clarence and his crew are miracle workers! Not long after I started at my current job, all four of our furnaces broke down at the same time. I called a bunch of HVAC companies, but they all said they couldn't help. I was starting to lose hope that anyone would even come out to take a look. Then I got in touch with Clarence. When I explained what was happening, he came out the same day to check all four furnaces and gave me an estimate. There were a few new steps for both of us, but we worked through it together! As soon as my estimate was approved, I called Clarence, and he said they’d be there in two days with all the parts to get started. Clarence and his team repaired all four furnaces and cleaned everything up in less than five hours. I was so impressed with how quickly and professionally they worked. The team was respectful and efficient. About a week later, I noticed one of the fans wasn't working. I called Clarence, a bit worried since we had just fixed the furnaces, and he came out within an hour to check it out. Turned out it was just a bad connection to the old thermostat. He suggested we replace the thermostats, and within about a week, he came back and got the new thermostats and breakers installed and working perfectly. We are really happy and looking forward to working with them again!

    we had a really good experience getting our old ac replaced and upgraded. the team made everything easy and smooth, so we also had them fix our furnace. when i called to set up a time, they were able to come out the next day and put in the new ac and the circuit in about six hours. clarence was fantastic and always got back to us quickly with answers to our questions, even when he was away. i highly recommend their ac repair service. the whole crew was great!

    we recently had to contact an hvac company a couple of times. the first time, they quickly fixed our downstairs thermostat at a really good price. the second time, they replaced our upstairs hvac system after it had been running for many years. we’re happy to say we’ve found our reliable go-to hvac contractor. kai, who worked with us, really understands when it’s right to repair or replace a unit. his prices beat out the bigger companies, and you don’t get stuck paying extra for big overhead. on top of that, he noticed we’re veterans and gave us a special discount, which we really appreciated. it’s great to see a company still taking care of their customers like this.

    I reached out to Harmony Heating & Cooling for a quote after contacting a few other places, and their offer was by far the best. I got a new Trane furnace and a 75-gallon State water heater that work perfectly with our State A/C unit, all for a great price. Kai and the team arrived right on time in Westminster and finished the installation in just four hours. They made sure everything was set up correctly, tested all the systems, and explained how to use everything, including tips for the future. I'm very happy with both the new furnace and water heater, and especially impressed with the professionalism, quick service, and value I received!

    Kai and Lucas spent the whole day installing a Mitsubishi combination heat pump and air conditioner on the third floor and outside our home. While setting up the outdoor compressor, they noticed we were worried it might block our window view. Without us even asking, they made sure to find a spot for the unit that didn’t cover any part of the window. They were very thoughtful, skilled, and worked efficiently. We had a great experience and highly recommend their HVAC services.

    i needed my furnace repaired and finding a reliable company was really stressful. after looking for a trustworthy furnace repair service for months, my landlord suggested this one, and they turned out to be very professional and fast. lucas came out right away, checked out my furnace, and gave me the best price. we scheduled the repair for the next week, and now my furnace is working perfectly, just in time for the cold colorado weather. they are licensed and insured, which gave both me and my landlord peace of mind, since a lot of places i called before weren't insured. really grateful for their great service!

    Harmony Heating & Cooling installed an HVAC system in my home many years ago. After decades of reliable service, the air conditioner finally stopped working right before a holiday weekend, just as I was getting ready for a big celebration. Even though it was late in the day, four technicians, including Lucas, arrived at my house with the new AC unit and had my home cool again within two hours. The installation was done quickly and at a much better price than another HVAC company had offered. The team showed excellent professionalism and really cared about making sure I was comfortable for the holiday. Five stars!

    I have used Harmony Heating & Cooling for heater repair at both my home and business. Every time, they have gone above and beyond with their service. They always respond quickly to my heating needs, and their technician, Lucas, has been very professional. I appreciate supporting a company that gives back to our community, especially to local schools. They are always the first to help out with donations for school fundraisers. I am grateful for their excellent service and positive impact on our area!

    when our old heater stopped working unexpectedly, we got a few quotes from different companies for the repair and replacement. we chose this company because their price was fair and they could install the new furnace quickly. they even called us to offer an earlier appointment when another job was rescheduled. kai and clarence, the technicians who handled the installation, were very polite, knowledgeable, and kept us updated throughout the process. there were no hidden fees or unnecessary sales pitches, and the job was done in just about four hours. it’s only been a short time, but the new heater is running smoothly and keeping our home comfortable, which is important with how cold it gets in colorado. i’m really pleased with the service we received.

    We recently needed a furnace installed in our home, and we reached out to Harmony Heating & Cooling for help. Clarence was our salesperson, and he was incredibly attentive to our needs during the consultation and bidding process. He was fantastic at returning messages and answering our calls as we made our decision. While we received lower bids, none matched the excellent communication skills Clarence provided—he truly made us feel valued as customers. Once we decided to proceed and made our deposit, they continued to impress us. The installation was completed a day earlier than expected, and the installers were efficient, friendly to our pets, and made sure to clean up every day. The furnace works even better than we anticipated, and we are extremely satisfied with every aspect of our experience. We believe a 5-star rating doesn’t fully capture how great it was, and the project went smoothly with no unexpected surprises. We highly recommend this company, and Clarence was an outstanding liaison between us and the team. You've earned our business for life! Overall, it was an amazing experience. Kudos to everyone involved; we are so happy we chose Harmony Heating & Cooling!

    I highly recommend this company for your HVAC needs. They installed a new 3-ton, 2-stage heat pump split system in my home, and I’ve been very happy with it. Their team comes out every six months for maintenance to keep everything running smoothly, and they also change out the whole-home air filter during each visit. On the most recent service appointment, I asked if they could install a soft starter to help reduce the starting and running amps, since I’m preparing to get a home generator. Clarence handled the installation, and everything went perfectly. Every technician I’ve met—whether it’s been Clarence, Kai, or Lucas—has always been professional, friendly, and clearly knows HVAC systems inside and out. Living in Colorado, where the weather can be unpredictable, it’s great to have a team that understands how urgent it is when you have heating or cooling issues. I appreciate their quick response times and reliable service.

    i called this company to take a look at my furnace because it was making a strange noise, especially after i had trouble getting help from another larger company. clarence, the technician, was fantastic in every way. from the friendly team who answered the phone to the quick scheduling, everything went smoothly. they fit me in for a furnace repair much sooner than expected, which was a big relief with the cold weather in colorado. i really appreciate how professional, courteous, and knowledgeable they were. if you want your furnace fixed right by people who care, i definitely recommend choosing this company over the bigger ones!

    After several other companies said no because the ac repair job was too complex, this team in westminster stepped in and replaced the old, broken hvac system in my condo. The job took a few days and needed a new line set installed through the building, which was a big challenge. From the start, i felt confident that i was getting true professionals, not just the only folks willing to try. kai, who came out to look at the project, spent a long time figuring out exactly how to get the work done—checking the ceiling, stairs, and all areas of the building. Later, clarence, the project manager, double-checked everything and made sure there were no surprises. The quote i got was for a high efficiency ac and heating system, but the price was about the same as what others offered for a basic one. When it was time for installation, lucas and his crew showed up right on time, acted professionally, and kept everything clean. It wasn't an easy ac repair, but they handled it calmly and got the job done right. Every question i had was answered quickly by the office staff, who stayed friendly and helpful. for top quality ac repair in westminster, i highly recommend this company. i am extremely satisfied with their work.
