“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,
Art Parker (Jeff Wesche, owner of Duplex). 5701 Park Ave. 28403 (Jeff is 5703).”
