Get matched with top central a/c installers in Elmwood, MA

"We are overall very happy with the project. Sila had to install a high velocity air conditioning system in very limited space. They provided a timely quote and showed up and did the work professionally and on time. There were a few hiccups, such as the installation of the hatch to the attic space, but Sila’s carpenter agreed to fix the problem at no additional cost to us, so I consider that to be excellent service. After two weeks, the system has been performing exactly as we hoped."

"Outstanding service and professional installation!!"

"My Central AC unit went out; the box outside smelled like something had fried. I called NETR, and they said they would send a technican over in a week. The technician came on time and promptly inspected the unit. He reported that the capacitor had blown, and told me that he had a spare back in his van. The labor was covered by the diagnostic site visit fee, it was just the parts cost. I told him to proceed and he replaced it. My AC was back up and running within the hour."

"The house I purchased was built in the 1950's. The house had the duct work for forced hot air but was heated by oil. Ross installed a natural gas furnace, coordinated for the removal of my oil tank and installed central A/C. The quality of the work was great and so is Ross's professional manner. He and his team were very efficient. I would highly recommend."

"Dylan has done a wonderful job installing my Mini Splits. Dylan was professional, worked hard, cleaned up, and completed the job in a timely manner. Also, he answer all question and kept me updated throughout the job. I highly recommend him to install A/C."

"The sales team and installers were professional and responsive. I had contacted other companies for quotes. Peter and team came right away and were considerate of my home and health. The others were not. When looking at my home they gave me the options needed for our unusual configuration and home history. They wore PPE and were meticulous . So happy to have a climate controlled home!!! If that is what you want call Majic!"

"The install team of Mynor and Steve were very professional and knowledgeable. They worked efficiently, explained the operation of the new unit well and left the place cleaner than they found it."

"Seamless. From the moment of making the appointment with the sales rep to come out to the follow-up phone call, I could not have asked for this installation to go better at a difficult time. They listened to my concerns regarding the look on the outside of the house and the location of units inside. They assisted with all aspects of the Mass Save program making the application process easy. They took care of actual submission of the paperwork where most companies wanted to provide the info to me to then submit."

"Carl and Henry were so great to work with. From first contact to complete install was super fast. Most of the "wait time" was working thru the Mass Save Program (which Carl was also super helpful with). They removed the old burner and installed the new one in a day with no issues and zero mess left behind. Already have a plan to work with them for central air next season. I have zero hesitation to reach out to them for any project."
