"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!"

Customers say: True professional

"Our heater stopped working around 7 pm during the night, last Feb 2026. We had no heat for the whole night so it was really cold inside the house the next day. To our relief, Mark was able to come out the very next day in the morning. Mark checked and tested numerous devices on the furnace. He explained everything that he was doing while repairing the furnace. He was here for only an hour and got our heat going again. He's friendly and trustworthy. He is our Plumber and we call him for any problem. His rates are reasonable. We highly recommend him. We live in Brockton 02301."

"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."

"My gas water heater was leaking and starting to get a bit old... so I needed a replacement. Boston Standard gave me an estimate after emailing them a few photos of my existing setup, and came out to replace it the next morning. Their estimate came in lower than another company I looked at by a fair amount. They also gave me a discount on a scratched water heater they had on hand that another customer rejected. The were prompt, professional, and got the job done quickly. I will absolutely hire them again for my plumbing needs."
