Company Overview

O'Brien Service Company operates as a locally owned and managed entity. Founded in 1981, our mission has always been to deliver a full spectrum of heating and air services (HVAC) in Wilmington, NC.

Established in 1981, O'Brien Service Company is a locally owned and operated business focused on providing a complete range of heating and air services, from installations to ongoing maintenance.

Jimmy Williams, born in Wilmington in 1961, attended schools in New Hanover County and graduated from the Machine Trades program at Cape Fear Technical Institute in 1984. In July 1984, he joined the City of Wilmington Fire Department after applying for a position there.

Williams has attended The Church of God of Prophecy on College Road since he was a young boy. The pastor requested volunteers to take an HVAC course at Cape Fear Technical Institute to service the six units at the church, and Williams volunteered. Williams graduated from the program at Cape Fear in 1986.

To build his skills, Jimmy offered his services on a volunteer basis to Donald O'Brien. With a reputation for exceptional HVAC knowledge, O'Brien was someone Williams wanted to learn from. In time, he would take over the company from O'Brien.

This company has the BEST customer service. I called this morning before they opened, left a message and got a call back in MINUTES! They got a tech out to my house in a couple of hours and this fella is out there working on my A/C in the pouring rain. My house is already cooling down!!! I Whole-heartedly recommend them!!! I have to purchase a new system soon and will be working with them.

Our downstairs (Main) HVAC went out in the 99degree temps. Ouch! The unit was original to the house and about 17 years old. We interviewed and priced a few of the local HVAC companies and decided upon O'Brien. Took about a week to get scheduled, but Richard and Will braved the heat and installed a new 3 ton, 18 SEER Trane in about 4 hours. Cost about $8800. Expensive - yes. Worth it - yes.

These people are as good as it gets . They explained everything that was going on with my unit. Got me up and running first thing in the morning . I am so glad I read the reviews online before I picked a company to use. I will keep a contract with this company forever. They kept in contact with me the whole time and didn't charge a arm and leg to get me going again .now I found out the sell filter and deliver them too. So great.

As a customer service manager myself, I can say that all the staff that my wife and I came into contact with at O'Brien's was above and beyond our expectations. We called around to get quotes from other Heating & Air companies in the area, but no luck on even getting a call back. When we did decide to call and set-up an appointment for a sales call it was on Memorial Day weekend, I didn't expect a call back but with-in an hour or two Mike R called me back. This blew my mind since it was a holiday weekend. After the long weekend Mike R came out on Tuesday for us to select a unit and pick a install date. Some how the cards fell in our favor and O'Brien's was able to come out that Friday. Michael arrived with his install team sharply at 8:30 to start replacing our old unit. Michael and his team did an awesome job on the install and I know they had several obstacles to over come with this being an old house with old wiring and a crawl space that is indoors. I know in the future I will need heating & air work done and will definitely be calling O'Brien's.

Great response time. Professional employees from initial call to end of service. We had no working AC in a recently purchased older house. For an unscrupulous company, this would've been an opportunity to oversell service or a new HVAC system, but not O'Brien's. Chris Harris, our service tech, quickly identified the problem and addressed it for a small service call fee. Very impressive. Liked them so much we asked to signed up for a yearly service contract.

I do not know how we happened to find this company but the stars alined and we found them. We live at the beach part time and the sea air kills the AC units. So as of now we can expect to arrive at the beach to find something a miss with the AC system.

This companies customer service is always polite, caring to our issue and work diligently to schedule a technician for our AC fix.

I wish our fixes were not in the oppressive heat of our attic. The technicians are hard workers, knowledgeable and work under harsh conditions. We always have issues resolved with new parts if needed in a relatively short time and the balance of our summer is comfortable thanks to them.

Glad we got the package, its paid for itself many times over. Thank you for your consistency!

Chris was very professional. He explained everything thoroughly and even took the time to show me exactly what he was talking about and why the repairs needed to be made. He provided me with options and even gave me suggestions on the maintenance that should be done in order to get as much life out of my system as possible. He even showed me how to use my gas fire place, haha. Excellent customer service. Great job, Chris!

I cannot say enough positive things about the exemplary service I received from O'Brien. From first contact to completion of service, I got the very best. I was very pleasantly surprised that I was able to get same-day service. My technician, Matt, was courteous, professional, and kind. He explained the issues with my system and showed me the malfunctioned part he replaced. I have never had such a positive experience with any previous heating and air company. O'Brien now has me as a customer for life!

They quickly concluded that our existing system needed to be replaced. For options, they tried to sell us on a lot of things we didn't need. Got the base package installed and it worked for 2 days and then was intermittent. Had their service tech come out who couldn't find anything wrong. I ended up finding an issue with the control board and found out that they had re-wired the board during install. When going over the contract, we told them that we didn't want a new board because ours worked fine. When i asked them to replace the board, they became defensive saying that the fine print on the contract excluded them from having to fix any board issues. But it is apparent that the work they did created the issue. After being jerked around, they finally said the fine print was a CYA for them - their install team can't be held responsible. It is like getting your car brakes replaced, then your tire alignment is off afterwards, and they claim it wasn't their fault.

You can't get much better than a company like O'Brians. They fixed a 7 year problem I had been having with another company and their professionalism and knowledge far passed any other company I have worked with. They stand behind their work and are polite and helpful if you do have any concerns. I only wished I had used them from the beginning!
