O'Brien Service Co

Christian was very professional, personable...he was prompt. We were very happy with the service received.

Derrick was prompt, professional, and very friendly. He completed all of the maintenance requirements. Derrick is a nice addition to O'Brien's team.

My wife and I have owned our commercial building for 20 years and have dealt with four or five HVAC companies. We needed to replace our old HVAC units and O’Brien was highly recommended. I cannot compliment them enough for their work! From working with them on the estimate to the installation, they were efficient, professional and offered suggestions that saved me money. They communicated with us and followed through on all commitments. They will have all of our business from now on!

Not good, the A/C quit working the next day after the tech serviced it

All went very well. Polite, professional service.

Mr. West, was very knowledgeable, I was impressed By his professionalism.. I need an appointment, for Someone to come give me a estimate for, new duct work, And A/C.. unit… sometime in November.

Excellent. Quick but thorough work and patient explanation. He must be a valuable employee.

Everything went well! They were able to install the new unit sooner than expected. The guys, Mike, Riley and Andrew were professional, friendly and very efficient. They cleaned up any debris and made sure I was satisfied with the work. Mike Russell is awesome too. I have used O'Brien Service Company for many years and I trust them completely. Thanks, O'Brien, for another outstanding job!

Excellent - could not have been better. Prompt, professional, competent, and very nice people to deal with. They are the best.

Many thanks to Jim Z for the 2 days he spent getting my Trane system working properly and correcting some old problems. Jim is a true HVAC professional with many years of experience. O'Brien is fortunate to have him on their team. It was such a relief to have this friendly, yet no-nonsense pro, on October 7 & 8, 2020 handle persistent problems with focus and ease. I have consistent cooling and heating again. And, my electricity expense, which had doubled, is back to normal. Also, many thanks to Holly & Chris for their Sunday service call in March & for making sure of proper follow-ups. As always, O'Brien is the best. Happy New Year

Outstanding work by O'Brien Services. From the "diagnostic" visit to scheduling and the extensive repair we were impressed with the knowledge, experience, professionalism and thoroughness of the O'Brien team. O'Brien prices were reasonable for the amount of work done. Highly recommend O'Brien Services and kudos to Mike, Rich and Eric for their outstanding customer service.

When our HVAC system failed, we started looking around for a company that we would like to have a long term relationship with. Our neighbors had just had a Trane system installed in their home and were very happy with both the Trane unit and the company that did the installation: O’Brien’s. We spoke with a couple of companies, but O’Brien’s stood out. First, Mike Russell responded to our call immediately. He came to our home, and before discussing any new systems, did a complete inspection and calculation of what our home required. He then sat down and gave us multiple options of manufacturers and SEER ratings. He helped us narrow the systems down to what we decided on. We were able to schedule installation the very next week. Mike Bennet was our installer. He showed up with his team on time each morning and kept his workspace immaculate. We were very impressed with their work, and they were nice enough to repair a couple items that they found improperly done by other companies. Our system had one glitch the first week, but Tim Morehouse had it fixed before we returned home, then returned later to confirm all was well. Overall, we are extremely pleased the entire operation at O’Brien’s. We’ve always found that when you find a contractor that you can trust, stick with them. We are now loyal O’Brien’s customers.

The salesman (Tom) was involved and available throughout the whole process from providing multiple alternative quotes and advice to a follow-up visit after installation. The installation team showed up on time and worked straight through till the system was installed. They walked me through setting up the system, app and thermostat. The cleanup was well done and complete. O'Brien did a great job and I wouldn't hesitate to recommend them. A very professional company.

They are above excellent and I would highly recommend them.

Absolutely no complaints at all. Appointments were kept, and all players were courteous, respectful of our property, and they clearly knew what they were doing. Everything was clearly spelled out and reviewed prior to the start of work. Follow up was also punctual. The system so far is working perfectly. Pricing was fair too insomuch as you don't get what you don't pay for. If I had it to do over again, I'd hire these guys in a heartbeat.

We are scheduled for February, and put the request in November

Part one: I called for an evaluation and a Mr. Getzen, the technician, arrived. He did this long introduction of the service. Part two: The actual installation couldn't have been better. Courteous and competent technicians handled everything. Absolutely a great 10 on everything. Part three: Mr. Getzen comes back. First of all he shows up a quarter to 1pm instead of 11:30am without an explanation. He says we owe him an additional $576 and I said I don't because I paid what was advised by check and they received the receipt. I was told that they made a mistake but I said that's their problem, not mine. I was also suppose to receive a gift card through the AC vendor but offered to give that to the company so I won't be charged the additional fee they mentioned. Mr Getzen declined the offer that I made so he packed up and left. I had a bad experience with the interactions overall but the installation went well. I called the company to have them not have the technician come back so instead they had given me new contact card with the superior's information. The beginning and ending were negative experiences but the middle, the installation, was positive.

Professionals from start to finish. Will use again when it’s time to do the upstairs

They are a very good company, excellent reputation and service in Wilmington area, you highly recommend them; extremely courteous and always on time, and extremely reliable workers.

Perfect. heating and cooling costs dropped by 150.00 per month. house very comfortable. work done promptly and clean up too.

Person arrived on time. Was very professional and competent. Answered my questions plus provided some suggestions. I was very pleased with his service and plan to use them for the next HVAC check up.

could not have been better! Arrived on time, neat, clean, professional & could not have been nicer. And most importantly: competent.

We just bought our house in November and had Josh over for our annual service. He took the time to explain everything about the system as we have never had a Heat Pump before. He is the ultimate professional and look forward to having him service our system on a regular basis.

Excellent service! Everyone involved with the project arrived and finished on time. We had one small problem noted 10 days after installation. Technician was at the house and had the problem fixed within 3 hours of my phone call. We are very pleased with the service.

Everything went as told. Tom showed up on the day and time to give estimate. Estimate was accepted and was told they would install unit on Friday. Guys should up on Friday as planned and did an excellent job. They were very careful to not scratch up or mess up anything in the house and cleaned up after job.
