What Our Customers Are Saying

Steve R.

“Matt was very courteous and professional. Not only did he do a great job fixing our problem, but he was very informative about our options for the future. “

Cathy & Mike R.

“Company is locally owned, highly competent, and responsive to your needs. Their techs are highly proficient in trouble shooting problems and very professional. O’Brien does an excellent job of following up on trouble calls and installations”

Lori & Corey N.

“We have had an excellent experience with O’Brien Service Co. They are organized, professional, and detail oriented. I highly recommend them.”

Cherry H.

“Every experience with O’Brien has been great, from last year’s installation to this year’s annual Tune-up. Trace, the tech who did the tune-up yesterday was right on time, answered all my questions, and did a thorough job. He was pleasant and personable, too! All in all, a top notch job from a top notch company! “

Deena & Mark S.

“The salesman, Scott, was very receptive to my questions and took the time to explain things thoroughly and honestly. The 2 who placed the unit in our home, one is named Rich, were very friendly and respectful of our home. They did the job in a timely and efficient manner. Rich was very helpful in explaining the new touch screen thermostat and answering my questions. We will need to have additional duct work added when we finish off a few rooms on the 2nd floor and look forward to working with this company again .”

Rose R.

“From the rep who took my call for information, to the sales rep who came to my house, to all installation personnel, total professionals, a pleasure to work with.”

Julianna & Stanley W.

“O’Brien Service Co. is not for those who are working for the lowest price. I believe you get what you pay for and we have been pleased with every employee we have dealt with – sales person, office personnel, installers and technicians.”
