Overall the work appears to be well done and the workers were helpful and descriptive. They arrived promptly and got the work done quickly. My only complaints would be that they messed up our basement stairs bringing in the new system (which will need to be fixed and re-painted) and they forgot our UV light which I had to remind them of. It was corrected the same day but had I not said anything it may have been left out. But they did fix some issues that I was not aware would be fixed so it was a welcomed surprise and I appreciate their willingness to go above and beyond what was expected.

Donnellys team supplied us with a new cast iron boiler just in time for the winter season at a reasonable price. They also flushed out our hot water heater. Great service

Nick was extremely competent and friendly. Our hot water heater was leaking and we had no hot water.
Nick showed me what was happening and replaced it. He explained the new heater.
Nick also made an important recommendation to replace a valve on the water coming into the house. We need to schedule this with our water supplier first.
