“We have been O'Brien customers for years and have been very happy with the quality of their work and their responsiveness. My wife recently heard a faint sound coming from our HVAC system. Concerned, she called O'Brien to check it out. The technician quickly determined that there was a water leak involved and located the break. The problem required both HVAC and plumbing expertise to resolve. If left alone, the problem could have turned into a major catastrophe. O'Brien assembled a combined team of HVAC and plumbing experts that same day and they were able to fix it before we had a major problem. Kudos for a job well done.”
