Winter in Grafton, Ontario is not a joke, so if you have any reason to worry about your heating system it is better to call a local company sooner versus later for furnace repair. Delaying furnace service in most cases will not save you any money, and may even leave you in a hotel room for a few days as you cannot live in a Grafton home without heat in a few of the colder winter months. With this in mind, now is the time to start thinking about repair if you have noticed any of the top warning signs that your furnace is not behaving as it should.
