No heat at 5:30 in the morning in January. Tech was here by 7, had the part on the truck, done by 8:15. Price was exactly what he quoted.

Karen L., Rowley

Replaced our water heater the same afternoon we called. They put down drop cloths, wore boot covers, and took the old one. Would not call anyone else.

Dave and Priya M., Newburyport

Honest. Told us the boiler had a few more years in it instead of selling us a new one. That is why we will buy the new one from them when the time comes.

Tom B., Ipswich

Called on a Sunday with a flooded basement. They picked up. That alone would have earned five stars.

Mark R., Georgetown

Third time using Northfield. Same tech every time, which I did not expect from a company this size.

Linda S., Topsfield

Quote was clear, work was clean, and they explained what they did. Boring in the best way.
