Jan 03, 2021 Report
After nearly a half-century of use, the boiler motor in my house gave out. The company I'd used a couple years ago gave me an insanely high price and a long list of skeptical and unnecessary work. I called A&J Mechanical for a second opinion and I have been amazed and impressed at the quality of work. In less than 24 hours, my boiler was repaired and the new motor was quietly humming away. The motor should last another couple decades but if/when the boiler finally dies, I'll only trust them to fix it and perform general maintenance. Can't recommend highly enough!
