"I’ve been a customer of Northern for almost 20 years. They take care of my furnace and central AC which are now 26 years old. Northern comes twice a year to service my heat and air. They are always on time, professional, helpful and knowledgeable. They explain everything to me. I recommend them without reservation."— Candace Love
