We service both gas and electric furnace systems with manufacturer-trained technicians.
Heat exchanger cracks, ignitor failures, and gas valve issues all fall within our scope.
Furnace failures carry a safety dimension — carbon monoxide and gas leaks — that most other hvac repairs don't, so the diagnostic has to start there, which is exactly why furnace repair calls in Biwabik, MN get treated with urgency, not a next-available-Tuesday slot.
