HVAC reviews in Littleton, Colorado

Aaron was able to schedule us same day and showed up on time. He was thoughtful and genuine in his assessment of our issue. I would work with Aaron again. Highly recommend!

Got a referral from a friend and gave Aaron, the owner a call. He came out within the hour and gave me a diagnosis of what was wrong with my furnace. He was so professional and courteous. I had heat within four hours. Highly recommend Small Heating and Cooling LLC.

Aaron and his son do such a wonderful job at an affordable price. We have used their services for years. You should definitely give them a call for all your HVAC needs. You’d be getting a great value and supporting a local, fantastic family business.

Aaron has serviced our geothermal heating and cooling system, which includes three geothermal heat pumps, for the past two years. His impeccable attention to detail, technical understanding of heating & cooling systems, and timely responsiveness keeps me coming back to him for any scheduled maintenance or repair services needed. No need to compare to any other service provider because he is the ultimate professional, and I trust his advice without question!

Aaron came out and diagnosed our furnace quickly and definitively. Truly appreciate his services. He provided sound recommendations and was very genuine and honest.

I’ve had Aaron work on our geothermal HVAC system for years. After cycling through quite a few HVAC companies and having all sorts of problems, I eventually found Aaron and he was able to fix everything. He’s very knowledgeable, friendly and professional. Also his prices are good. Having a geothermal system is significantly different than just a HVAC system as I found out the hard way and it’s a great relief to know that whatever happens I have somebody who can always fix it.

My experience with Small H&C was outstanding! Aaron was easy to schedule with, and showed up on time. He diagnosed our furnace issue, fixed it within an hour, and now our furnace operates better than ever before. The pricing was more than fair as well!! Highly recommend!

Excellent job. Both Joe and technician Russell from Harmony Heating, Air & Electric were professional, polite, and well-informed. Russell took the time to explain the necessary AC repair work in a way that was easy for me to understand. He was tidy, wore a mask and shoe covers, and cleaned up after himself. After completing the repair, he ensured I fully understood the work he had done. He is one of the finest technicians I've ever had the pleasure of working with in Littleton. I am thoroughly satisfied with both Joe and Russell.

The entire team at this exceptional HVAC service is outstanding. Damon displays remarkable customer service skills, providing thorough information on every air conditioning system he presents. Joe and Taylor have visited my residence in Littleton twice to install an AC system and unit. Both are incredibly approachable individuals. Manuel did a fantastic job installing the Halo air purification system, another impressive professional. I also had the pleasure of meeting their manager, Arthur, who was equally impressive. I wholeheartedly recommend their services to my family and friends. Thank you, guys!

During a routine maintenance check, it was discovered that our furnace had reached the end of its lifespan. Emmanuel was able to install a highly energy-efficient unit within a week. This new system not only operates incredibly quietly, but also features continuous fan control. We are extremely pleased with this upgrade. Although we hadn't anticipated needing to replace our furnace just yet, it wasn't entirely surprising given its age of almost 29 years. We felt confident in working with the team to update our HVAC system. They were punctual, knowledgeable, and professional throughout the entire process in Littleton. We are very satisfied with their service.

I first engaged Harmony Heating, Air & Electric for a project involving the fabrication of a gutter section and two sets of upper/lower skylight saddles, along with the corresponding step-shingles. The time span from placing the order to picking up the finished product was just a few days. The craftsmanship was outstanding and the precision was top-notch! Not long after, my furnace's circuit board malfunctioned. I reached out to Russell who promptly returned my call. He listened carefully to my description of the problem and immediately sent out their service technician, Taylor. On the very same day, Taylor came to my place in Littleton, assessed the situation, and identified the faulty board. In no time, he sourced a replacement board, informed me of the labor and material costs, and gave me the option to choose a convenient day for him to return. The following day, Taylor came back, installed the new board, tested it, and ensured everything was functioning properly. Most importantly, he made sure I was completely satisfied as a customer. The customer service, workmanship quality, and follow-up provided by the team was exceptional! I can't praise them enough. There's no doubt that I'll be using their services in the future.

Our heater stopped working right when we had a cold snap, and we have a 1-year-old and a 4-year-old. Many places were booked for two weeks, but I managed to set up an appointment with a local service. They had a busy schedule but were doing their best to help everyone. I called on a Thursday, and later that day, they informed me that a technician could come out the next morning. Since our old heater needed replacement, we decided to get a new one. To help us get through the weekend, they worked on making the old heater functional for a few days. Their team was very supportive and provided us with all the options available. They aimed to install the new unit the following Monday, but they couldn’t make it. However, they called to apologize and assured me they would arrive first thing the next morning at 7, which was the original plan. The technician arrived right on time and efficiently replaced our heater. He also checked all the vents to ensure they were working properly and even went the extra mile to assist us with a few additional requests. We are extremely grateful for their service and will definitely reach out to them again for any future needs.

i don't usually write reviews but harmony heating, air & electric really impressed me. my ac stopped working on a really hot night in littleton. people in my neighborhood suggested this company, so i called and damon was able to come out the very next morning (other places told me i'd have to wait weeks). damon was great—friendly, professional, honest, and easy to talk to. he went above and beyond fixing my ac, even finding parts quickly when needed. as a new homeowner, it's a huge relief to know i have a reliable ac repair company now.

After receiving numerous quotes from various heater repair services in the Littleton area and a suggestion from a neighboring friend, we opted for Harmony Heating, Air & Electric. We couldn't be happier with our decision! There were no aggressive sales tactics, only genuine and honest assistance. Harmony Heating, Air & Electric's rates were unbeatable, and their warranty surpassed any of the other competing services by 2.5 times. All of Harmony's technicians, including Russell, Emmanuel, and Manuel, who handled the installation, were extremely professional and knowledgeable. They not only arrived punctually and completed the job as per schedule, but also went the extra mile in accommodating our desired furnace placement and answering all our queries. When we noticed a minor rattling sound in the furnace, Emmanuel was at our doorstep within hours to fix the manufacturer's defect. The service Harmony provided was unparalleled, from the initial estimate, through the installation, to the subsequent repair. Trust me, they truly are the best in the business!

a couple weeks before we were set to leave for vacation, we discovered water leaking from under our old boiler. at first, we tried calling a different hvac company, but after waiting days for them to show up and getting no answers, we were pretty stressed. that's when we found harmony heating, air & electric. even though their phones were down from a power outage, they replied to our online request in less than half an hour. taylor came out the same day to check out our boiler and explained everything clearly. since we needed heat and time was short, we decided to get a new boiler installed. taylor called us the next morning to confirm a crew would be out in just a few days. when installation day came, emmanuel, damon, and another team member arrived early, got right to work, and were super friendly and professional the whole time. they spent hours making sure everything was done right, not just replacing the boiler but also updating all the old, inefficient parts around it. now our heating system runs smoother and more efficiently than ever. we’re so grateful for how fast and reliable the crew was. they really saved us from a big headache, and we’ll definitely recommend them to anyone who needs heater repair or replacement.

Reliable, trustworthy, and experienced. Joe was prompt and thorough. He wore a mask when he arrived at my home. The first time I needed furnace repair, Joe diagnosed and fixed issues with my new heat pump that had been installed by a home warranty technician. He discovered that my heat pump and furnace were incorrectly wired and low on refrigerant. I called for help again when my older furnace had some issues, and Joe quickly identified the problem, completing the repair in just about 30 minutes. Their prices are quite fair as well. I highly recommend their services.

we had to replace our old ac unit after it stopped working. harmony heating, air & electric gave us different options to choose from. we picked a high-quality system because it was just a little extra. we also upgraded to smart thermostats. installation was on time, and joe made sure to tidy up the old vents and some plumbing. we are really happy with our new ac and heating setup and would definitely recommend this company.

I discovered Harmony Heating, Air & Electric while searching for 'thermostat repair' when my thermostat stopped working. They were the second company I contacted, but they were the first to get back to me. Unlike another company I reached out to, which took hours to respond, Harmony responded to my request in just 15 minutes and had a technician on-site the same day to fix my thermostat. The technician who assisted me was Manuel. He was polite, knowledgeable, and straightforward. He offered a very fair price for the high-quality work he provided, which came with a warranty, and I was extremely satisfied with the results. The entire process was quick and smooth. I was so impressed with Manuel’s work on the thermostat that I called him again later to address a concern with my HVAC unit's efficiency. He did a fantastic job once again. Manuel and his team genuinely care about delivering top-notch service. Working with them was a great experience that gave me confidence. I feel assured that 1) the job will be done right, and 2) my investment is worthwhile. I wholeheartedly recommend their services.

I had a tricky problem with my AC unit in Littleton. It kept shutting off randomly and was hard to figure out what was wrong. After years of getting help from Harmony Heating, Air & Electric for AC repairs and installations, I decided to call them again. Damon came out to check the issue, and within minutes he found the problem, explained the repair in simple terms, and I was really impressed with his knowledge and how clearly he communicated everything. He arrived on time, worked quickly, and knew exactly what to do. I’ll definitely ask for him again if I need more AC work. As always, you can trust this company for fair prices, great service, and top-notch technicians.

We recently decided to have our furnace replaced in Littleton, and after meeting with Emmanuel from the company, we chose them for the job. Emmanuel noticed that the cold air returns in our basement weren’t up to standard and helped us find solutions that fit our home’s unique needs. We also decided to add a mini split system to our bedroom for extra comfort. The installation team was professional and friendly, arriving on time and working efficiently to get everything set up as promised. Once the installation was finished, Emmanuel scheduled a walk-through with us to check that everything was installed properly and working well. He took the time to answer all our questions about the new furnace and the system in general. We are very happy with the service and highly recommend this team for anyone in Littleton needing furnace repair or heating and cooling services.

Updated review We have been using this furnace repair service in Littleton for over three years now, and they continue to do a fantastic job! We got their furnace maintenance package for our house, and also had them check the heating system at our cabin. Damon and the team are knowledgeable, responsible, dependable, and their prices are very fair! It doesn’t get better than that—I still highly recommend them! Previous review Great experience! We called them for two different issues—installing a new furnace in a small building and repairing the furnace in our home. Both times, they arrived quickly and acted very professionally. They kept us updated the whole time and even came back on a Saturday to make sure the job was finished! We will absolutely use them again and strongly recommend their furnace repair services!
