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.

    We worked with Lauren Mushrush and Derek Reed of Breen and Sullivan and they were incredibly easy and professional to work with.

    Our newly installed generator failed to work the first time we lost power after installation and no one from the company will respond.

    Edit: The company has reached out and corrected the problem.
