The Nashoba Air and Boiler Works team arrived on schedule with all the parts and equipment to replace our oil furnace. The workers made appropriate measures ( drop cloths and feet coverings) to avoid and soiling of floors and carpets. They removed the old furnace from the basement and then commenced the installation of the new furnace. During the process the team was joined by other Nashoba to undertake special tasks (sheet metal, electricians, other technicians) to complete the install process. The team worked seamlessly and professionally together in completing the install in one day. I was impressed by their team work and they left the job site very clean. I highly recommend Nashoba Air and Boiler Works for your home HVAC needs as they provide responsive service and a competitive price.
