"WORK NEEDED TO DO INSATLL WENT WELL. INSTALLER WAS VERY INFORMATIVE.EXPLAINED EVERYTHING NEEDED FOR THE JOB IN DETAIL. VERY PROFESSIONAL."

"I recently asked Nick to remove an old cast iron boiler from my basement, and I couldn’t be more impressed with his service. From start to finish, he was professional, efficient, and extremely knowledgeable. The job wasn’t easy, cast iron boilers are bulky and difficult to maneuver—but they handled everything with great care and precision. They showed up on time, worked diligently, and made sure to keep the area clean throughout the process. The crew also took the time to explain what they were doing and answered all my questions clearly. What really stood out was their attention to detail and respect for my home. They protected my floors, cleaned up thoroughly afterward, and ensured everything was in great shape before leaving. I highly recommend Nicholas Gouveia Plumbing and Heating to anyone looking for reliable, skilled plumbing services. I’ll definitely be using them again for any future work!"

"They responded quickly and installed the system within 2 days"

"I appreciated being able to speak with someone in the office to explain my situation (leaking water heater), and having someone come to my home so quickly to go over my options for dealing with the problem. Dylan, Aaron and the entire crew were so professional and knowledgeable about the on-demand hot water system we chose to install. They were a pleasure to work with, and I would highly recommend them to friends in need of similar services."

"Majic Air did a great job of listening to our desires. We wanted to install central air conditioning in our two story home. We did not want ductless wall units. Shawn, the salesman, was able to come up with a plan that combined traditional ducted AC for the first floor of our home with ductless ceiling cassettes for the second floor of our home, completed with one wall unit for our finished third floor office. We have the air conditioning we wanted and the look we desired. The installers were professional, hard-working, and incredibly neat - leaving us with a tidy home each day. This was a complex job, and Majic Air got it done."
