What Our Customers Are Saying

Susan M.

“Brent was amazingly proficient and knowledgeable.  He performed a whole house diagnostic and we were up and running within days.  Both technicians that performed the install were very pleasant.” -Susan M.

Patricia H.

“Chris H was great. He explained everything to me, he was neat, professional and my whole experience from start to finish was excellent. I am even going to take advantage of the yearly contract where they come out and check your unit, based on the information Chris shared with me. I will call O’Brien the next time I need heating and air help.” –Patricia H.

Greg W.

“There is a reason why we gave O’Brien the highest marks. They earn it with courteous, reliable and professional service. The O’Brien Company is well represented by its staff in the community.” –Greg W.

John R.

“Chris and assistant arrived within the appointment time, they proceeded through the maintenance inspection in an organized manner, asked questions, explained an issue found and how it was resolved. Another customer who looks forward to a long relationship with O’Brien Service.” –John R.

Alan H.

“They have always done a great job installing and servicing my AC/Heat Pump systems. They have installed two new systems for me: a downstairs duel fuel system and an upstairs/attic heat pump. It’s a reputable company with great people, prices and service.” –Alan H.

Carol S.

“Excellent service both on the technical side and the sales side. Very thorough and thoughtful and easy to work with. As a matter of fact, all my communications with O’Brien have been excellent. I recommend them highly.” –Carol S.

Bob D.

“From start to finish the work O’Brien Service Company performed was simply amazing. They removed two older HVAC systems (upstairs and downstairs) revised the ducting layout in the attic, and installed a new Trane XV20I air handler HVAC system. At every phase of the tear out of the old systems and installation of the new systems they were efficient, cleaned up everything and performed an outstanding job. I wouldn’t consider using any other company for any A/C system work and highly recommend O’Brien Service Company.” –Bob D.

Kim S.

“Recently had my heating/air conditioning unit’s annual service performed. My service technician, Matthew was punctual, courteous and knowledgeable. I highly recommend O’Brien to all of my friends and neighbors.” –Kim S.
