What Our Customers Are Saying

Emily and David G.

“We have two service contracts for our homes with O’Brien. We have used them to install 2 new units and they have responded to all concerns promptly and with high quality service. Matt came over recently to see why our AC was not pushing out cold air. He fixed the problem in minutes. Ahh! Highly recommend! “

Jodi D

“These guys were great! They were prompt, friendly, and polite. They brought us window units to use over the weekend when we had a family gathering for graduation, since our installation wasn’t scheduled until a few days later. They explained everything well. I love that their photos are online. The ladies in the office were wonderful too! This has been a very easy experience. VERY professional!”

Patrick D.

“In addition to being prompt, courteous and direct, the service technician (Chris J) was thorough with troubleshooting and diagnostics and left me reassured with the level of quality of the repair. “

Mark B.

“Trace came on time and even called when he was on his way. Found the problem quickly and fixed it right away while showing and explaining exactly what the problem was. Obrien service co is not the cheapest but they do a great job and I would recommend them. Trace has been to our house twice to fix different problems and has been outstanding.”

Abigail C

“O’Brien is a great company. This is the 2nd HVAC system we have bought from them and this time we got the dream team. Mike was exceptional during the estimate and quote (I was difficult!) and Mark and Justin, his helper were excellent. Mary Alice, part of the office team is also top rate. These staff members are assets to this company because at every turn, they do the right thing, go the extra mile and stay professional throughout.”

Anthony G.

“From sales representative to installation team. I was very satisfied with service preformed. Professional manner, follow up and excellent payment option. Already recommended to neighbor.”

Anne J.

“From estimate to installations to inspections, I have rarely worked with a company whose employees are as courteous, knowledgeable, and concerned with total customer satisfaction and happiness as those at O’Brien Service Company. I recommend them without reservation.”

What our customer's are saying about us...
"I had another company check my heat pump after an over $500 electric bill. The company said that the compressor in the outdoor unit was not working and needed to be replaced. He gave me what I thought was a very high estimate to fix it, especially since the part was still under warranty. I decided to call a few other companies and get a ballpark estimate what it would cost to replace the compressor and as I suspected all were lower than the company that found the problem. I decided to have O'Brien come to the house, since they said that they do 2nd opinions for free and they had good reviews on Angie's List. The O'Brien technician that inspected the compressor verified that it was not working, but he also found what may have been the cause, a link in one of the coils. They fixed both in a timely fashion and the cost was still lower than the original estimate for just the compressor".
