People standing behind an HVAC unitO'Brien Service Company is a referral based business, and we want to reward our loyal customers for their support.  If you refer a new customer for replacement of their HVAC system, be sure they mention your name when contacting O'Brien.  That way we can send you a "thanks" check!

"Tom B. is my salesman and he went thru the house and crawlspace to verify which unit would work best. Other companies did not. I asked quite a few questions and he answered understandably. The numerous reviews helped a lot in choosing O'brien. Scheduling went smooth and 10 days and on time work started and finished that day. Brian the installer kept working thru this july heat wave and so did the two electricians and O'brien driver who delivered and helped Brian put it in place. The following week the inspection was done and passed. My neighbor referred me so he was given a 50 gift card. Another thing they have is 24 hr phone service. I called on a saturday night and they called back monday morning. Other companies it just rang and rang. Give the local Wilmington company a call, O'brien." -Henry I (Wilmington, NC 28409)

Besides system replacement, we also have a newer referral program for our Energy Savings Club.  See the details below.

"Recently Chris H. from O'Brien Service Company performed our annual HVAC system inspection. I found Chris to be very knowledgeable, courteous and informative. Chris addressed all my questions, performed a thorough inspection during which he found a couple of minor issues which he corrected. I was very pleased with Chris' professionalism and would recommend him and O'Brien Service Company to my neighbors and friends." -Jeff S. (Leland, NC 28451)
