    Breen & Sullivan Mechanical Services, Inc. provides excellent service. Their technicians are knowledgeable, friendly, and prompt. They offer thorough maintenance and repair services, going above and beyond to ensure customer satisfaction. Their work is done efficiently and with attention to detail, and they prioritize cleanliness, leaving the work area spotless. Customers appreciate their fair prices and would highly recommend the company to others. Timothy from Breen and Sullivan noticed that the dryer vent was not hooked up in the attic, a potential fire hazard, and connected the customer to the sheet metal group. John came out to fix it and worked creatively and carefully. Both Tim and John were personable and professional. Guss “Gustavo” in service is amazing. He fixed the residential AC system which had a leak and today he installed a new thermostat and did the AC service. He is a hard worker, very clean, respectful, honest. Breen and Sullivan were generally quick to respond to an HVAC need. Andy and the team worked through a challenging condensation issue in a fair and professional manner.
