Wilmington, NC, Commercial HVAC Installation and Replacement Services


You can rely on O’Brien Service Company for the professional installation, repair, and maintenance of your business's heating and cooling equipment. We ensure every system runs efficiently and quietly, enhancing the comfort of your commercial space.

  • What is the cost of a new commercial HVAC system?
    The price depends on the unit's size and specific features. For example, a small-to-medium-sized commercial property will differ from a larger commercial building. The capacity of the system and its energy efficiency will also determine the price point. At O’Brien Service Company, we believe in transparent pricing and providing detailed quotes to help you make informed decisions.
  • How do I know if it is time to replace my commercial HVAC system?
    Typically, well-maintained systems last around 15 years. However, if you notice rising energy bills or frequent repair needs, it might be time to consider new, energy-efficient equipment. That way, you can enjoy maximum efficiency and comfort for your customers, guests, and employees, while also reducing your heating and cooling costs each month.

  • What does it mean if my commercial HVAC equipment is making strange noises?
    These could be indications of underlying issues. Our O’Brien Service Company repair specialists are adept at identifying and fixing minor problems before they escalate into bigger, more expensive ones.
  • Is it better to repair or replace my commercial heating and cooling system?
    Generally, if your HVAC system is relatively new or the damage is minor, repairs might be the best option. However, for more severe issues, especially those not covered under warranty, upgrading to a new system might be more economical and efficient.

We back our repair work with a warranty at O’Brien Service Company. Contact us to get your commercial HVAC system back in top condition.

  • How often should I maintain my HVAC equipment?
    Regular maintenance is crucial to keep your system running efficiently and to maintain your warranty. It’s akin to regular oil changes for a vehicle.
  • What are the advantages of professional commercial HVAC maintenance?
    Benefits of professional HVAC maintenance include inspection, cleaning, and prompt resolution of potential issues. Regular maintenance can improve your commercial HVAC system’s energy efficiency.
    According to the U.S. Department of Energy (DOE), commercial buildings consume 40 percent of the energy used in the United States, so imagine reducing a portion of that and how much you could save in heating and cooling costs each month!

Client Reviews

“I was very pleased with the communication, response time and excellent service provided by O'Brian Service Company. Ryan took care of everything needed to address a problem with my water heater. He identified the issue, communicated with me regarding options, offered his professional opinion and then had the issue remediated the same day. He was kind, professional and eager to help.
Kyle followed up with a very thoughtful call later in the day to ensure that everything was fine and the tenant at the house had his needs addressed.
This is a responsive, thoughtful and professionally operated company with amazing individuals who care about you and your needs, issues and problems. Look no further if you need assistance.
Thank you, Katie”

“O’Brien Service Company just installed my new HVAC system and I am thrilled with the job they did!! I knew they’d be great as they had previously installed my daughter’s system and I’d used them before to service my old system. They were fantastic every step of the way. They came right away for an after hours visit for a diagnosis. Kris Sciales came the next day and gave the most thorough and understandable estimate for the new system. Not a doubt in my mind he knew what I needed. Agreed to proceed and Alex came next to get the layout specifics. Got the new system installed later that week by Eric and Jackson. They were there all day, and I came home to everything finished and perfect! Amazing job by two super professionals!! Thank you, Eric and Jackson! Smoothest work I’ve ever had done! So happy, I got O’Brien’s to come back and clean my ductwork, too. Jordan came for that work and did a fabulous job, as well. Kris returned the next week for the safety inspection and we were all set! I highly recommend O’Brien Service Company and especially this extra fabulous team of people involved, including project advisor, DeeAnne! Thank you!”

“Repairmen Eric and his other(name escapes me) helper were absolutely GREAT!! Worked from 9am till 5pm to install a new system in a tight spot in closet.
They really knew the job and were very polite and interesting to talk to.
I will definitely recommend O’Brien when the A/C kicks the bucket.
ALSO THANK YOU FOR THE TWO LOANER WINDOW UNITS. REALLY SAVED THE WEEK & WAS COOL ENOUGH TO SLEEP.

THANK YOU,
