A wall-hung high-efficiency boiler, installed by HMS
Westborough borders Shrewsbury, where one of our owners grew up, on the east side of the area we serve. It sits right where the Mass Pike meets I-495, and we cover the whole town, Lake Chauncy area included.
Whatever you have, an owner answers the phone, estimates on new systems are free, and any diagnostic fee goes towards your repairs.

Heat pump, boiler and coils
HMS is the best! After hearing that we had no hot water, Ryan made time to get out to the house and quickly diagnose what the problem. We needed a new boiler. HMS came up with a fair quote and the boiler was installed within 48hrs. Highly recommend.
