My husband did a lot of research when we realized that we needed a new furnace. After countless weeks of getting qoutes and references, we decided to go with Northwood. We are very happy and pleased with our choice. Gary and Brian completed the instaltion with profection and with no disruption to our family. They explained what they did and what we need to do to maintain our furnace. We are so pleased with their work that we have recommended them to many of our friends and neighbours.
