What Our Customers Are Saying

Ken A.

“I own a beach house in Carolina Beach. O'Brien Service Company installed a new heat pump last year and a free service was included. It was easy to schedule an appointment for the annual service for a Saturday. Chris H. was the tech. The service was on time, with a call when in route to my house. I could not be happier with this company.”

Marlene D.

“I have had O'Brien Service Company since I moved to Wilmington 16 years ago. They graciously kept my old heat pump going as long as possible, and then I purchased a new one from them two years ago. They are always prompt, pleasant, very careful about keeping my floors clean while going in and out, and eager to answer questions. Matthew B. serviced my heat pump most recently and left me with the same favorable impression all others employees have.”

Richard B.

“The entire process was smooth and easy. After the first day, I had some concerns that were immediately dealt with by a supervisor. Price was high, but you get what you pay for. They are the best in town.”

Terrill and Wanda M.

“Salesman very pleasant, knowledgeable and took time to explain heat/air systems and answer questions.  The two installers were extremely courteous.  Both took measures to not soil or damage inside our home.   Gave us instructions on use of new systems and answered questions.”

Beth B.

“Excellent! Only company on time, actually 10-15 minutes early. Felt like they valued my time, was very professional, polite, explained options easily, follow up to the work and was very clean when work was done.”

Elizabeth D.

“Matt Hayes, a service technician from O'Brien arrived to give a second opinion on a leaky coil. Matt first explained exactly what he was going to do and seemed very knowledgeable. He was courteous and ON TIME. Kudos to O'Brien's!”
