“Matt B was a great representative for O'Brien's. I had a new unit installed and he was with me from beginning to end. Really was good at explaining the choices for each unit. The installers also did a great job.”  -Nancy R. (Wilmington 28405)

“We have been customers of O'Brien Heating and Air for approximately 13 years. Love the fact the technicians are always professional, always on time (or call if they are held up and running a few minutes behind) and always knowledgeable. I really appreciated Josh R. during our most recent maintenance check, and his attention to our system, letting me know all that he did, and making me aware of a possible upcoming issue. All the technicians I have met over the years have been pleasant and professional, taking time to explain everything to me. Thanks to Josh and all the other men over the years who've helped us! And to the office staff who work to schedule appointments convenient to clients!” -Nancy M. (Wilmington 28409)

“Matthew was friendly and knowledgeable and made the whole process very easy. Our installation actually came early as they had an opening and called to see if we wanted to take it and the day of installation the men that came to install the HVAC were nice and polite and I hardly even knew they were here. Great service and would highly recommend them.” -Stacey J. (Wilmington 28405)

“O'Brien installed my new Trane heat pumps 10 years ago and they have been performing the annual inspection every year since then. I probably have met all of their technicians and every one of them have been very professional, courteous and knowledgeable. My last inspection was a month ago and Aaron was the technician. I was very impressed that he was so thorough, as though it was the most important thing he would do all day. He took the time to explain everything he was doing and pointed some things that would be helpful to me regarding my two systems. My experience with O'Brien Heating and Air has been a very positive one and I highly recommend them.” -Pat P. (Wilmington 28409)

“Will arrived promptly, was very pleasant, and explained exactly about the maintenance he was performing on the system. He answered my questions. thoroughly. I will be contacting O’Brien about a potential problem with the system that I asked Will about during the service call. O’Brien has always done a great job through more than twenty-five years.” -Elaine B. (Wilmington 28412)

“Larry came promptly and in a friendly and professional manner completed a thorough inspection of our HVAC units. He explained in layman terms how they were fairing and what the potential problems that may occur. He is an asset to this company and I would recommend him and O'Brien's to anyone with an HVAC.” -Warren R. (Hampstead 28443)
