What Our Customers Are Saying

Richard W.

“Always provides great service and exceeds my expectations. They arrive promptly or keep you in the loop for any potential delays allowing a re-schedule if needed. I have an annual service contract and they provide a very thorough inspection of my complete system with a uncomplicated explanation of their findings. Highly recommend them as a service provider for either routine maintenance or a complete replacement of your unit! A satisfied customer for almost 20 years now!” –Richard W.

“Mike, the salesman, came and gave us an estimate. Great guy. Gave us 3 options and did not push the most expensive one. Jonathan, the installer, was on time and worked very efficiently.” –Crystal P.

Steven R.

“Mark and Justin did a fantastic job installing our new system. It was a warm day and they worked non-stop to get it done. They were courteous, efficient, friendly, and when they left, they left everything looking the way they found it. Mike was the Design Specialist and sold us a great Trane system. Looking forward to seeing our next electric bill. You won’t go wrong with O’Brien Service Co.” –Steven R.

Patricia P.

“I have used O’Brien for many years (20+), as have several of my friends, and I believe they are head and shoulders above the rest. Their technicians are always knowledgeable and respectful and they make an effort to educate the homeowner. I’m not sure how they compare in price, but I’m confident I always get my money’s worth.” –Patricia P.

Arlene M.

“The entire team from the design specialist to the installers were very professional. I was very pleased with my total experience and the results I got.” –Arlene M.

What our customer's are saying about us...
"Our old unit died on the hottest day of the year. O'Brien lent us two window units to keep our house bearable until the new unit was installed. Their level of customer service is exemplary".
