“O'Brien was recommended to me by my friend who owns Comfort Master Heating and Air in Zebulon NC. O'Brien has been servicing my units at the beach ever since. They are on time, honest and very thorough.” -Frankie P. (Ocean Isle Beach 28469)

“First time using O'Briens but had been reading reviews. Was able to get appointment within 24 hours. Chance (service tech) called to say he was on the way and was at my house within 10 minutes. Talked about my heating concerns and he went straight to work. Went over everything when he was finished and gave me a couple of tips. Very professional. I will do service with them again.” -Sarah L. (Wilmington 28411)

“Have been using O'Brien since we moved here in 2006. Never an issue. Great staff and service techs. Excellent service plans too. Would highly recommend them.” -Tony C. (Wilmington 28409)

“We had a great experience with O'Brien - from my first phone conversation to completion of HVAC repair. I first spoke with Steele who offered experienced, professional advice after having a negative experience with another company. Our technician, Josh, was professional & performed his repair work diligently despite working in below freezing temperatures. Josh listened & absorbed all the details I gave him about our HVAC system. He worked to help us achieve a successful outcome. Working with O'Brien has restored my confidence in HVAC companies - but now that I've found them, I will no longer shop around. Thanks for your excellent service O'Brien!” -Beth H. (Wilmington 28403)

“O’Brien called to confirm appointment the day before and the tech called us when he was 10 minutes away. The tech was polite, efficient and talked with us once his inspection was completed and answered all our questions. We would gladly have our tech return for our annual maintenance.” -Loretta P. (Leland 28451)
