"Steven showed up and was able to repair our AC after two years of multiple repair companies that could not help. Everyone else said we had to replace when Steven was able to determine that it just needed a quick repair. He was professional and so pleasant. English is not our first language but he was so patient with us. Highly recommend!"

"Responded immediately to the side effects of a water break in the house. Immediately restored electrical services to dry areas, came back a few days later to restore more services. Gave detailed proposal before work was initiated, had enough supplies on truck to immediately replace most of affected parts. and advised on purchase of replacement fixtures. The technician was cheerful and understood my goals in restoring service."

"They came to my home showed me what needed to be done and they went and got the water heater. When they came back a short time later they had the tank and installed it in an hour with new pipes and a new shout off that I can do."

"We obtained 4 quotes for installing a new boiler and hot water heater. AllPhases was competitive with the quote and Carl was very responsive to our questions. He also had experience working with MassSaves so we will be getting some pretty large rebates (~4k). Ken, Elander, Henry, Fred and Caesar took out our 60 year old furnace and installed a high efficiency system that should meet our needs for years to come. They worked over 3 days to complete the job and left it cleaner than when they started. There was an error message on the boiler the night after the install and Elander/Henry came by early the next morning to fix it. They have come back 2 more times to troubleshoot and everything is working great. Ken and Elander have also answered other questions I've had about the system since the job was completed. I have no complaints and would highly recommend AllPhases Mechanical to family and friends."

"Called Burke and Sons to replace a ruptured how water heater, they were prompt in getting over but not much else was good. Two very young guys came over and did the work. They were not very professional but the job got done, so I didn't really care. I never really check the area where the heater is, and today I was in that closet and it's a mess. One of the vent pipes seems to have a leak and there is a bit of mold on the floor underneath the tank. The previous tanks in that spot had been there for almost 20 years with no such issues. Also, since it was urgent, no hot water, I didn't get prices which was also a mistake. My neighbor (condo complex) needed a new tank about a month later but got prices before having the work done and paid about 850.00 for the exact same setup that cost me 1150.00. I actually ran into the guy bringing his tank in and I stopped to talk to him and he was amazed at how much I paid, and asked if there was an office where he could leave his card. He figured he woud get a lot of business, being that much cheaper."
