The technician, Jared LeClair, arrived within a couple of hours of my call (on the hottest Saturday of the year) and went straight to work replacing a capacitor and repairing a damaged duct. My house cooled from 90 degrees to 76.Thank you Jared and O’Brien for saving my weekend. I have always been pleased with your service.

Kevin came out to help us very quickly, even though it was after hours and he wasn't technically on call. All the techs were booked up and so he went above and beyond for us. He also showed me what he was doing every step of the way, so I could learn as he worked. Great experience!

I recently had issues with my air conditioning system and when I called O’Brien they were super helpful and were able to get someone out the same day to asses the problem. Thankfully they were able to get a part the next day and had my system up and running. Service technicians Joey and Kevin M were knowledgeable, professional and very polite. Lydia was also super helpful in scheduling my service. I would highly recommend this awesome company!

I was thrilled with the service provided by OBrien. Matt really took his time going over all the options with me, answering all my questions, and completing all the paperwork needed for my rebates and warranty. DeeAnne, at the office made scheduling around my difficult work schedule a breeze. John and the install crew were clean, fast and courteous. They worked hard on a hot day to get my A/C up and running yet I hardly knew they were there.So happy with how everything worked out. I highly recommend O’Briens!

Jonny came out late for a faulty blower motor service call . Motor would not start and needs to be replaced. Jonny put in the order and I spoke with Angel the next morning and she told me the motor was in stock and scheduled me for that afternoon . Jonny called in route arriving early! Jonny replaced the motor and got us back in AC quickly. Jonny did some system checks, pressures, temperatures, Amp draw and capacitor check as well as condensate drain. Service was very professional, detail oriented from a Technician that really enjoys his work.Thanks Jonny!Highly recommend O’Brien to all my friends and neighbors.

Efficient, professional, lovely team of young techs who did the job right! My house was cared for as they worked for nearly 8-hours installing my unit. It was a hot day yet these guys didn’t miss a beat. Eric, Jackson, , and Javon. From estimate to install, I’ll take O’Brien every time!

O'Brien Service Company recently replaced all the air flow tubing on our HVAC system and installed a media filter. It started with Kris, the salesman that visited our home, inspecting the system, addressed every question we had and prepared a reasonable offer that compelled us to retain O'Brien to perform the work we needed done. (We interviewed 3 of their competitors as well.) They even offered us a 3 year interest free loan, that we took advantage of!! Will and his team were great to work with. While the temperature in the attic was 130 degrees the 3 of them were undeterred and completed the job in the time planned for the removal and replacement of the air flow tubing along with making improvements in the air flow to rooms where there was barely any air flow coming thru the vents. Their tenacity in making sure we were satisfied was obvious in everything they did. Highly recommend talking with O'Brien if you have need of the services they offer. Janet and Larry Gorski

We’re thankful we chose O’Brien Service Company to install our new HVAC system. Their professionalism throughout the entire process shined above the rest. Everyone we communicated with at O’Brien‘s was detailed, organized, kind, and knowledgeable. Matt Childree was wonderful throughout the quote and design process including providing options for relocating the new HVAC system to a more ideal location. Gauge Hancock and the other team of installers treated our home like their own, but more importantly, they did an amazing job with the install and kept us informed during the installation. Thank you to the O’Brien team for giving us peace of mind and confidence knowing we chose the right service company.

O’Brien Service Company was great AGAIN! Never had anything but the best work done by O’Brien.

Thrilled with the visit by Tyler and the bill only about $400 including a year of service plan. Only place to go for a/c and heating needs! Thanks!

We highly recommend O'Brien Service Company for water heater installation. They were very knowledgeable and were able to answer our questions and accommodate our needs. We received a fair quote with no hidden fees and stuck to it. I cannot say enough good things about Kyle and Ryan work effort. They worked efficiently, removed the tank, left our place very clean and were also able to walk us through on how our new system operates. Great price, great customer service. We would absolutely use them again."

20:32 26 Jun 26

Unfortunately Obrians was very late in arriving as we waited all day for a plumber to clear our kitchen sink. They finally showed up as tech was finishing up a job 10 minutes away in Calabash. The price given to me the day before was $124 to clear the clog. Upon arrival the plumber quoted $537 for a 15 minute job. He stated the $124 was a dispatch fee. The office listened to the recording and it showed a discrepancy in detail. The dispatch invoice will not be paid. I don't know how they stay in business.

Great experience from start to finish! Our design specialist, Jeremy, did a great job of explaining the benefits of replacing our old system with a Daiken system and helping us feel comfortable and confident with that decision. We're glad we did! Our installers, Mike and Pierce, did a great job! Worked tirelessly and efficiently, were very respectful to our home, and did an excellent job of explaining different parts of the system to us! Our contact with O'Brien, Heather, has been great keeping us informed and responding to our calls! We've been using O'BRIEN Service Company for many, many years, will continue to use them, and HIGHLY Recommend The O'BRIEN Team for all your HVAC needs!! Danny Pearce

Eric and Jackson need a raise- and motorcycles! They were polite, professional, extremely funny- and they are the two cutest installers at O’Brien! Kris also very nice and great sense of humor! No one wants their AC to give up- but if you can laugh through it, eases that financial pain significantly!

Greg Thompson

16:25 17 Jun 26

We discovered what appeared to be a water leak inside a wall around 7pm one evening. We called the after hours line and within minutes Kevin (HVAC supervisor) diagnosed the problem over the phone as a plumbing issue and referred it to an Obrien plumber, who come out right away. Chris was our plumbing technician and he was professional, courteous, and knowledgeable. He fixed the problem quickly, charged us fairly, and we had the problem solved by 9pm the same night. We could not have been more pleased.

Rene Denis

23:17 16 Jun 26

I was able to get same day plumbing service for an issue that was created by a handyman that I hired. When the service tech came onsite, he quickly identified the issue. He went above and beyond to get the parts that were needed and got my problem resolved. Very professional and courteous.

Give O'Brien a Chance, you will be relieved you did! Licensed Chris Perry provided excellent customer service. Chris repaired our leaky garden faucet in under an hour here in North Chase Wilmington.

I don't write many reviews but I had to for the amazing job the team of O'Briens did at our house. Our old HVAC unit finally gave up the ghost after 20+ years of service. Kris was very helpful with sales information and explained the process in an easy to understand way. The installers Mike & Pierce were awesome at installing the new unit! They took their time, were very neat and did a great job! The process from sales to installation was top notch. For anyone needing HVAC services, O'Brien Service Company is the best!

We had Obrien install a complete new HVAC system on our first floor and could not be happier with the entire process of working with them. From the first visit, going over our home space, to the financial options and finally the installation team, everything went absolutely smooth, was totally transparent, and we’re looking forward to being part of the Obrien family.

We had a great first experience with O'Brien Service Company. We called for a commercial AC inop issue on a used Bard unit we had purchased and installed ourselves. Where most companies wanted nothing to do with this type of service call, O'Brien was on location less than a few business hours and the technician was friendly and fully confident in working on our system. He was able to quickly find the issue and replaced the part right away. Now we have cold AC and at a minimal cost to get us back up and running. Thank you!

I wanted to take a moment to recognize the sales representative and installation team for an outstanding HVAC installation from O’Brien. From start to finish, the crew was professional, knowledgeable, and respectful of our home. The quality of workmanship was excellent, communication throughout the job was clear, and the install was completed efficiently and cleanly. We are extremely pleased with the overall experience and the attention to detail the team provided. Great job representing the company and delivering top-notch service.

Mart Cactus

We have 2 separate HVAC systems (upstairs and downstairs) and both were over 20 years old and literally held together with duct tape. One failed and we decided it was finally time to replace both systems. We got 3 quotes and OBrien was the middle one on price, but we really liked the attention to detail of their quote as they had measured the house square footage, where windows were, and did a full inspection of the existing duct work and vents. They'd also quoted for a variable speed system which is much quieter than a standard system and this appealed to us as the outdoor units are right by our pool. After accepting their quote and paying the deposit they scheduled 3 days for installation in around 3 weeks time. Installation of both systems went smoothly and on time - they found one issue with rust in existing ductwork and gave us the option to ignore it or replace it, and we choose to do that as it wasn't too much extra. The new system is working great, its virtually silent, and we love having the option to control it by an app.

The technicians who came by were very professional, knowledgeable, and courteous. We had the HVAC system serviced and the dryer vent cleaned. They discovered that the dryer hose had never been connected to the vent properly up in the attic. He had to do a lot of extra work to fix it and get it vented properly. I would definitely recommend this company and will be using them again in the future. Excellent experience. Thank you for taking care of this for us!

Karen Shor

Our hot water heater (which our builder put in our attic) went in the middle of the night causing water to pour down into our master bedroom closets, hallway and living room. The only plumbing service where I could reach a live person immediately was O’Brien. Their plumber, Anthony Butts, was at our home in 30 minutes. He expertly cleaned-up the mess and replaced the old hot water heater (with an assistant.) He followed-up with suggestions of ways we could avoid such a catastrophe in the future. He also pointed out a problem with our roof! Thank you O’Brien and Anthony for your prompt and professional service! Karen and David Shor

I have been sitting on this review for a year now while I've been enjoying the finest heating and cooling experience in my own home. I feel myself take a deep breath of fresh, clean, isothermal air as soon as I walk through my door each and every day.If it weren't for O'Brien, I would still be suffering through uneven distribution of heating and cooling because I'd still be using a system that was outdated and poorly configured. And also putting out over 70% humidity.O'Brien did a complete overhaul of my HVAC system: new air ducts, new boots, new supply vent registers that were actually sealed properly, and a brand new and energy efficient inverter system by Daikin.The biggest task was relocating our new air handler to our attic so that we could gain an additional return vent for proper circulation of air in our home. That entailed building a platform for the air handler to sit on, installing the air handler, and adding the proper electrical wiring and drainage for the system. All of this was done properly despite having to work within the awkward confines of our attic. At the end of each day, the technicians had a pleasant demeanor, having just sweat buckets while carefully working around fiberglass insulation baffles in the stagnant heat of my attic.We had been wanting to do this HVAC upgrade for a while but hesitated because we were worried about finding a reliable service provider that could properly complete our install without causing us further anxiety. When Jeremy came to our home for the free estimate, he was by far the most thorough out of the 10 to 12 contractors I had already spoken with. There was zero guesswork in Jeremy's process when he went through our entire house and did a room by room load measurement. He was the only one who not only did this, but also had the service manager come by to verify that his calculations were correct.After speaking with Jeremy, we actually got excited about spending money on our new system. It did cost something, but I fully believe that if you take the time to research and learn, you end up getting what you pay for. Jeremy was able to further my knowledge of all things HVAC, while also recommending ways we could save money. It was also very nice that 0% financing was offered, so we are happy to have spent the money.Now that it has been almost an entire year of being able to walk from one end of the house to the other and never experience even a minor fluctuation in temperature, I have zero regrets. What used to be 70%+ humidity is now down to 45-50% humidity with our new system! I am so thankful we went with O'Brien because it's a blessing to have such a reliable system that gives me comfort and peace of mind. With such a big project, there were many opportunities for things to go awry or for the installers to tell us what we wanted couldn't be done. Every service technician went above and beyond to make sure that every.single.facet of our system was fully replaced and brand new, no matter how small a nook or cranny they had to squeeze into.If you're looking for someone to service or replace your HVAC system, please call O'Brien. Choose them! They offered multiple options for us so we could "price shop", so save yourself the time and hassle, and just go with the people who really know what they're doing.TLDR: they have a really good Super Bowl commercial with their service truck jumping the WB draw bridge and I feel like that really shows how committed they are to getting the job done.
