HVAC reviews in Needham, Massachusetts

Outstanding furnace repair service—definitely recommend! My furnace wasn’t heating properly, but their technician, Clayton, got back to me quickly and was able to fit me in at the last minute. He clearly knew his stuff and took the time to walk me through the diagnostic process, checked important components, and explained what to look out for in the future. Clayton also replaced the air filter and made sure everything was running efficiently. The warmth in my home is noticeable now, and the furnace works great. Prices were fair with no surprise fees. I’m really happy with the service I received.

I have used this AC repair company in Needham a couple of times, both for my large basement and for a home renovation project. My first experience was getting heating and air conditioning installed in my 4000 sq ft basement. Oliver was very prompt, professional, and made sure everything was completed on time. He really went above and beyond to make sure I was satisfied. Later, I needed help converting an old heating system to a high-efficiency setup and adding a new 3-ton AC unit. The team also removed the old oil tank and installed a WiFi thermostat, so now I can control the temperature from anywhere. Everything works perfectly, even when running multiple showers for guests. The office staff, especially William, was very organized and efficient. Jace, the foreman, was professional and made sure the job was done right. If you need reliable AC repair or installation in Needham, this is the place to call for excellent service and great value.

William was excellent! He was very professional, friendly, and really knew what he was doing with our heater repair. William was flexible with my schedule and did a fantastic job fixing our heating system. We have several heating units, and he made sure to inspect and service each one, checked for any leaks, cleaned up everything, and ensured the system was running smoothly. His work was tidy and he was a pleasure to have in our home. He made sure we were happy with the repairs and even offered to come back if we had any issues once the heater was running full-time. I highly recommend Harmony Heating & Air Conditioning for any heater repair or replacement needs.

I recently had my furnace repaired at my home in Needham. Shawn and William showed up right on schedule and were both very knowledgeable and professional. Throughout the day, I had quite a few questions about the furnace and how it works, and they patiently explained everything to me in a way I could understand. Now I feel much more confident about how my heating system operates and how to keep it running smoothly. After finishing the furnace repair, they made sure to clean up the work area so well that it looked like no one had even been there. I highly recommend this team for anyone in Needham who needs furnace repair. They are honest, helpful, and truly professional.

We have only had great experiences with this AC repair company. When we first called them, we were having major problems with uneven airflow from our upstairs air conditioning system. Other companies told us the only solution was to add a mini-split to the part of the house not getting enough cool air. But when we reached out to this team, Oliver came out to inspect everything and explained a few different options. We chose to replace our old attic ductwork since it was worn out and not working well anymore. The price for the job was very fair, and every question we had was clearly answered. The crew finished the ductwork replacement in just over a day, and since then, we haven't had any more airflow issues. After that, we signed up for their regular maintenance plan, and now they come by twice a year to service our AC and heat pumps. We've had several different technicians over time, including Jace and Clayton, and every one of them has been professional and knowledgeable. Overall, we are extremely satisfied and would highly recommend their AC repair and maintenance services.

We were extremely happy with the furnace repair service we received! When our furnace suddenly stopped working, we expected it to be a stressful experience, but thanks to Oliver and Clayton from the installation team, everything went smoothly. The staff were very friendly, professional, and always respectful of our home, making sure to keep things clean during the process. They replaced our old furnace quickly and even installed a new whole house humidifier, finishing all the work in just two days. Oliver took the time to answer all of our questions, and the office manager handled all of the warranty paperwork for us, which was incredibly helpful. We highly recommend this company for anyone needing furnace repair or installation in the area – they truly go above and beyond for their customers!

We have been using Harmony Heating & Air Conditioning ever since our furnace was installed in our Needham home. We signed up for their annual furnace maintenance program, which sends a technician to us twice a year—once before the winter and again before summer—to inspect our furnace and make sure everything is working well. for a long time, we've had william as our technician. over the years, we've seen him become even more skilled, and he's always had a friendly attitude. he does a great job keeping our furnace running smoothly, and it's nice to see a familiar face come by each season. we are very pleased with the service and plan to continue with them for a long time.

William came by first to check out our heating system and give an estimate for the repairs. A couple of days later, Oliver led the installation of a new condenser and a two-zone mini split heater at our home, with help from Clayton. We had an older Sanyo mini split system that only provided cooling, and they replaced it with a modern Mitsubishi system that handles both heating and cooling. Oliver explained each step of the process clearly and finished the job efficiently. The cleanup afterwards was spotless. Once everything was done, he walked me through the new system and answered all my questions, even sharing some tips I didn't know before, even though I’m familiar with these systems. Working with Harmony Heating & Air Conditioning was a great experience from start to finish. I had looked into several Mitsubishi heater repair companies and saw their strong reputation. Now, after having the work done, I can say I’m truly impressed. This was easily the best home service experience I’ve had in years!

I couldn’t be more satisfied with the AC repair service I received! I usually don’t take the time to write reviews, but this experience definitely deserves it. So many companies these days either offer average work with high prices and poor customer service, or they only care about you until you pay. This company is different. When Clayton came out to our home in Needham to give us an estimate for a new AC and furnace installation, he made us feel comfortable right away. He was friendly with my whole family—even my young son who kept interrupting. Clayton took the time to involve him in measuring the house and talked with him about math, which my son really enjoyed. I had already gotten a quote from another company, but without even knowing about that, Clayton gave us an estimate that was $400 less, and he included a bigger, more powerful outdoor unit than what we had before. We even got a letter from another company promising to beat any written offer by 5%, but my wife and I decided to stick with Clayton because we felt he was honest and fair from the beginning. On installation day, everything went smoothly. The new AC units are much quieter and cool the house much faster than our old system. We even ended up with an upgraded 3-ton outdoor unit at no extra charge because of a mix-up with the supplier. Instead of rescheduling or raising the price, they just installed the better unit at no extra cost. As long as I’m in the Needham area, I won’t call anyone else for AC repair or installation!

Harmony Heating & Air Conditioning provided excellent and prompt service when other HVAC companies couldn’t help. Clayton clearly explained all the available heating and cooling options and recommended what would work best for our home in Needham. He took the time to answer all my technical questions about the different HVAC units we were considering. Shawn and Oliver handled the installation with care, making sure to protect our floors and leaving everything clean afterward. They took care of any concerns I had and managed the rebate and warranty paperwork for us. The new Ecobee WiFi Thermostat is fantastic, and our home feels more comfortable than ever.

I've relied on Harmony Heating & Air Conditioning for my heater repairs for many years and they've always delivered excellent service. They respond quickly whenever I have an issue, and are great at figuring out what's wrong with my heating system. Shawn was especially helpful when it came time to replace my entire heater—he explained different options and made sure I understood the energy-saving rebates and tax credits I could get. The installation team did an outstanding job, finishing the work quickly, neatly, and with a lot of professionalism. I highly recommend them to anyone in Needham who needs heater repair or maintenance.
