“We are so pleased. Our heating pump went out on a Thursday, you were there on Friday to invest the problem. When it was determined it was unfixable, you had our new unit in by the following Wednesday. Thank You O'Brien.” -D.B (Wilmington 28412)

“Chance was such a pleasure to meet and to have in our home. He updated our thermostats (installing Nest) and started us on a annual service contract. Extremely pleasant and skilled- we hope we will see him again on the occasions where we have HVAC concerns.” -Charlie S. (Wilmington 28411)
Muriel B. (Hampstead 28443)
“I was using a different service company to service my heat and air. They would spend approximately 20 minutes and tell me everything looked good. I used them for 2 years and every time I had a problem, I couldn't get in touch with them, each time I would complain and was assured the problem would be corrected. I started using O'Brien Service Company and Larry spent over an hour on each of my two units. He corrected a problem which had probably been there for two years. Larry Was on time, and very professional. Don't throw your money away using other companies, use the professionals at O'Brien's.” -Muriel B. (Hampstead 28443)
Robert B. (Wilmington 28412)
“Josh was our service rep, he was extremely through servicing our heat/air unit. He listened to the issue we were having and provided us with options that we may use. Since his servicing of our unit the heating is much more evenly distributed making the entire house more comfortable. Josh was very professional in his dealing with us and it came across to us that he is also proud of the company he works for, O'Brien Service Co. We highly recommend O'Brien Service Co.” -Robert B. (Wilmington 28412)
Thomas H. (Shallotte 28470)
“Matt is awesome. Five star service rep. Highly recommend him. Glad we chose O’Brien to service and install our new system. The price is worth it.” -Thomas H. (Shallotte 28470)
Herb S. (Wilmington 28409)
“Chance was on time, called prior to arriving. Was professional in the way he went about his job. As usual the service met the clients expectations. Best HVAC company in town.” -Herb S. (Wilmington 28409)
Roseanne L. (Wilmington 28411)
“When Larry the service tech came for my yearly inspection, he found a problem within the air handler that I would have never known about. Had it not been for the fact that I have the O'Brien service contract with them this problem would have cost me thousands of dollars. I'm so happy with the quality of service I was provided. Everyone at this company is wonderful, they are very professional and extremely easy to deal with. I highly recommend them.” -Roseanne L. (Wilmington 28411)
