We have used O'Brien @ our personal house as well as our 2 rental properties for several years now and they have always provided excellent customer service. We had an incident occur last summer at one of our rentals. It was a VERY hot weekend and the a/c went out. Mike, the technician on call, was very prompt and courteous and did not seem to mind coming out on a weekend. We hated to ask, he actually offered! He took care of the problem in no time and as a result we signed up for the Maintenance Contract which has turned out to be very beneficial and cost effective. Needless to say, we are very pleased!

We were not having any problems but had not had our unit inspected so wanted the peace of mind that everything was in good working order. The gentleman was prompt, courteous and professional. He did recommend one item be switched out as it was showing signs of wear and could lead to a bigger problem in the future. This item was not very expensive and he was able to do the replacement right away.

From the initial call, to the estimate, to the prompt response of questions, to the follow ups, to the scheduling of service, to the actual installation and to the efficiency of the installation was all PERFECT! Haven't had to call since the products were installed, but if I do, I don't expect anything less than a perfect response! My husband and I highly recommend O'Brien Service Co to anyone needing a repair or new installation of an heating/a/c unit in the greater Wilmington, NC area! We got a Trane, and that is what O'Brien sells! Highly recommend the Trane/Clean Effects too!
Description of Work: Replaced upstairs and downstairs central heat & a/c units, and had all duct work replaced both upstairs and downstairs.
