The service was excellent! At 70yrs old and limited income Luke got my furniture up and running quick. He also worked with me on the bill. Thanks North Star.

Everyone we were in contact with at Northstar Services was outstanding. Phone calls were answered promptly and every question was answered. Obtaining an estimate was very easy and the on-site visit was detailed and complete. The day of the install of the new Boiler went smoothly. Everyone was friendly and worked together well. We are extremely pleased with the result!! Karen and Steve Talbot

Very polite young men worked on the project, and left the basement cleaner than when they began. Excellent service, arrived on time, and were finished approximately when they indicated they would.
