At his visit at my request Mr. M****** was helpful, courteous. He listened to my request and advised me that there is no reason to add any other equipment to my heating system. This made me more trusting as, he was not interested in charging for unneccessary devices. I was not charged for his time or visit by his office.

The installa... read more

TF O'Brien did an excellent job in handling the service call for my HVAC system. In scheduling the visit they set up an appointed time window that accommodated my work schedule so I did not need to take time off. When the technicians arrived, they were courteous, efficient, honest and especially respectful of keeping my home as clean as possible.

Needed to have our boiler checked out duee to the cold weather. Called T.F. O'Brien who we've been using for years for both the A.C. and heating. Justin C. arrived when they said he would and made sure everything was working as it should. Good service. Stand by T.F. O'Brien and their employees.
