Peter installed our whole home dehumidifier when we first moved to Cape Cod 3 years ago. He did an outstanding job! Since then we have Quality Mechanical Systems come out to tune up our two unit HVAC system in the spring time, and then in the autumn they come out to do preventive service on the two furnaces. Angela runs the office; she is polite and efficient. Ethan is a young man who's been coming out for us recently, you can tell he was trained by Peter; professional, polite and efficient. I highly recommend Quality Mechanical Systems. read more

Outstanding service! Angela took my call. She was thorough in qualifying my issue and immediately scheduled Peter to come by the following day. Our a/c was not working. Peter discovered the cause of the malfunction: chimpmunk in the outdoor a/c unit. He removed the nest, replaced the damaged parts for a fraction of what it would have cost us with another company. Peter was knowledgeable, professional, responsive and very patient with this rodent terrified client! read more

Peter and his team were efficient and provided quality service. I will definitely use this company again for my future needs.

If you need any HVAC work done, call these guys and you won't regret it. They're the best of the best. Top top.

I called 9 other companies to service my air conditioner. Some did not respond, some had long wait times (week or more) , and another outrageous "high volume fee"of $400 just for coming out. Angela from Quality Mechanical Systems answered my call promptly and was so kind and helpful! Her husband, Pete, arrived and repaired my a.c. quickly and efficiently. He is such a nice, friendly guy. HIGHLY RECOMMEND THEM!! read more

Thank you Peter for your super, prompt and reliable service today on our furnace. It's working again like a charm. The only hvac company to use on Cape Cod! read more

Prompt attention and incredibly nice. Efficient beyond expectations. Service is exceptional. Installation was fast and affordable.

Bought my house in June of 2021 . It was a flip that some dirt bag did. Had issues with the HVAC since day one of buying the house. Tracked down the installation company which is this company. Had and still having airflow issues . Owner came out n mentioned the subs he used on this install he let go . Changed the filter added a bit of charge and ran for the hills. I had the feeling he knew it was more than a filter and corner's was cut on this install. I called the company back with no return call cuz they don't seem to back up what they install. I want to make it clear that I'm a easy going person not the kind that complains about everything. I'm in the contractor world myself and stand by my installs and quality of work . Sick of hearing short staffed issues as an excuse to hack people's home in any trade. If your going to install do it 150% take pride not just people money. read more

This Company is a family business that runs itself like a quality well-oiled Corporation. Pete and his team are responsive and courteous (with small business care) yet professional and top-notch (with state of the art equipment and processes). They installed 3 residential systems for me over the past 10 years and currently continue light maintenance (only when necessary) on all of them. read more

I was extremely disappointed with Peter Savary from Quality Mechanical Systems. He appeared punctually for an AC installation estimate but after promising an estimate within 72 hours we had not heard back from him in over two weeks. After multiple calls to track him down we finally heard "We are really busy. You should get other estimates if you want the work done before September." We are all busy. Honest communication regarding time frames was all that was needed. I would have sought additional referrals then. Now we are three weeks behind and will most likely be unable to complete our AC installation this summer. I would NOT recommend Quality Mechanical Systems. Peter was not trustworthy, honest or responsive. read more

Squeezed us in becase we were leaving town. Showed up early, solved the problem promptly on a very old system. No big upsell. Very polite. explained the problem and fixed it. Highly recommend. read more

Peter and his team are absolutely wonderful!! They are super professional, highly skilled, on time, polite, respectful-all the good things!!!! They installed our new high efficiency furnace last year and central A/C this summer. They really go out of their way to provide excellent customer service. We've been extremely happy with everything they've done for us, we will continue to use them and highly recommend them for any of your HVAC needs! read more

Great service and great price. We lost pressure in our steam heating system they were quick to respond and even came up to Belmont to help us out. It was a complex problem seeing our house was built in 1903 and not much has been done to update our system. Peter went over everything in detail with us and took time to show us how to even save some money. read more

These folks were recommended by a neighbor. They provided prompt and professional service at an affordable price. They installed a new 3.5 ton Carrier air condenser and evaporator coil within 5 hours on an 85 degree day. When it comes to any type of home service, you need a company that you can trust and rely on. The level of service that these folks provided exceeded my expectations. Don't get cheated by the bigger guys who rake their customer through the coals. Give these guys a shot. read more
