“Matthew B. was my technician that came to do my annual inspection. He went about doing his job while answering any questions I had. I have a faked wall around my inside unit. He removed the wall without getting flustered even with me wanting to be so helpful :) . I cannot say enough good things about Matthew or O'Brien's Service Company. I love my unit it does everything plus more than I expected.”

“We had an after-hours call on New Year's. Chris was the tech that showed up about twenty minutes after we had called in. He was polite personable and he even put booties on when he entered the house. I could not have asked for better service. Thank you”

Verl A.

“This was my first time using O’Brien and I was very impressed with their response time and knowledge of our system. The technician, Trace, was very thorough, and although this visit was a system planned maintenance request, he fixed a problem with the condensation drain that I would never known about. I highly recommend the O’Brien Service Company.”
