My central ac was not working and they got it fixed in about an hour. I highly recommend them. They’re very polite and clean and good around family’s!
I had an excellent experience with B&B Mechanical from start to finish. Brendan was professional, punctual, and clearly knowledgeable about his work. He took the time to explain the issue with my system in simple terms and walked me through my options without any pressure. He arrived on time, worked efficiently, and made sure everything was running perfectly before leaving. It’s clear he takes pride in his work and genuinely cares about his customers. I would highly recommend him to anyone looking for reliable and honest HVAC service.
I highly recommend the owner Brendan from B & B Mechanical for your heating/cooling needs, he helped relocate my AC compressor for a home addition I’m working on. The service was professional, the turnaround was fast, and the pricing was very reasonable.
