Questions and Answers
My furnace won't ignite on the coldest Minneapolis days. What's usually the issue?
This is a common problem in our extreme cold, often caused by a failing ignition control board, a dirty flame sensor, or issues with the gas valve. The intense cold can exacerbate minor electrical or sensor problems. Our technicians are experts in cold-weather furnace diagnostics and can quickly pinpoint and resolve the ignition failure to restore your heat reliably.
What are the signs of a cracked heat exchanger, and why is it so dangerous?
Key signs include a strange, metallic smell when the furnace runs, visible soot around the furnace, excessive moisture on windows, or the furnace frequently shutting off. A crack can leak carbon monoxide—a colorless, odorless gas—into your home's air. This is a serious safety hazard. We perform thorough inspections and use specialized tools to detect cracks that aren't visible to the eye, ensuring your family's safety.
How can I prevent these major furnace problems before next winter in Minnesota?
The best defense is a professional pre-season tune-up. We recommend scheduling service in the fall. Our maintenance includes cleaning critical components like the flame sensor, checking gas pressure and electrical connections, testing for carbon monoxide, and inspecting the heat exchanger for early signs of stress. This proactive care improves efficiency, prevents cold-weather breakdowns, and extends your system's life.
