"Hired Greg for a full gut and remodel of a bathroom. Greg was very competent, personable, and took the time to understand exactly what we wanted. He made us feel like we were in good hands. He took the time to make sure things were done the right way. The result was top notch, couldn't have asked for more. I would definitely use this company again!"

"Rafael did a wonderful job installing 3 zone split HVAC system. On time, very clean and neat install. All questions gladly answered, just a great experience."

"I highly recommend Eric. He and his partner are great and did the job JUST RITE. We're set for hot temps this summer."

"The crew arrived on time. They were pleasant to deal with, hard workers, and very careful in keeping the work areas clean and protected. After the installation of the Nest thermostat and Ring doorbell, time was spent with my wife and I setting things up and showing us how to take advantage of the features in these products."

"Everything went great. The crew arrived right on time and was very polite and professional. Ali explained everything beforehand and the work was done exactly as described. After installation there were some minor adjustments to be made and Ali responded right away and took care of the problem. He was also able to get the ducting corrected to a part of the house that hasn't had ac for many years. I was very pleased with Ali and his crew."

"The guys at MassAir made having to get new central AC units installed, repairs on older units, new vents and ductwork, etc., actually a pleasurable experience! It is a family owned business, and I found Joe and his son Michael to be a real pleasure to work with. They are an extremely professional, proficient, knowledgeable, honest and hardworking team, and I trust them with any HVAC related projects that I have in the future. I 100% recommend giving these guys a call for your HVAC needs! -Mike Vedder"

"Paul showed up at 8 as promised.. inspected the job an Attic Fan install & remove old unit . Did everything as he explained was needed & finished with everything completed 100% by 2 pm ! Great service hire this company they are totally professional"

"Jeff and his crew were amazing to work with! I have had some very bad experiences with previous contractors, and I never thought that I would have such a positive experience with a contractor. Jeff and his crew came in every day and performed their job - left end of the day everything clean and organized - not a mess. They went above and beyond and accommodated changes that I requested that were not part of original quote without adding to our cost. Jeff was courteous, helpful, on time, and worked on weekends as well to make sure job was done in given time frame. they even finished 2 weeks before they had estimated (was told 8 weeks, he finished in 6 weeks. I will definitely be hiring Northgate again in the future once I can afford to do more work to my house. I would 100% recommend Northgate to anyone looking for a contractor. Thank you Jeff & crew for the incredible work and professionalism."

"Jason completed the repair of 7 Oil heaters, full blower wheel replacements, nozzle head replacements, tune up and more. For the first time in 15 years all heaters run SILENT and they are 18 feet in the air in a mechanic shop of a dealership. He then served all 5 A/C units on the roof of the dealership. Ever since we hired him it has been seamless and very fairly priced. I would highly recommend him and his company. He's always available for any emergency we've had regarding the units."

"Had an outdoor TV / sound bar installed and programmed. These guys really extra mile for their customers. Would definitely recommend and will be hiring again as well."
