    Aj and jameel were amazing! They were both so quick and efficient. This is our 2nd time using Donnellys and we will always use them for any of our heating or air conditioning needs.

    Exceptional service completed by tech, Dan Kelley! He was extremely polite, communicative, professional, and courteous! Obviously, no one ever wants to need a plumber in their house, but if you’re going to have someone, they’re the way to go!

    I needed a water line break repaired leading to the supply line of a toilet. My house is over 120 years old so the plumbing is ancient. I called Donnelly and spoke with their service agent who was polite, informed and able to offer same day service . My Plumber Nick arrived promptly , was polite, efficient and highly professional. He wore booties when entering the house. He quickly determined the problem, documented with photos . I agreed to the repair quote. Nick was very careful to replace copper piping, clean and carefully connected a new t valve and then allow the pipe to cool before re opening the connection. Success !! I was very pleased with the quality and professional results. Pricing was a bit high but quality and timely result made it worth while .

    A very satisfactory experience. The tech, Shane Galvin, was clear laying out options and costs enabling me to make the best decision selecting the optimal solution. He implemented the fix, tested it for performance and left a satisfied, smiling customer. Highly recommended.
