Heating and Air Conditioning Tips
What to Do When Your Furnace Fails on a Freezing Night
Published 2023-10-01 · By David Anderson, Idaho Falls Heating & Air

When your furnace fails on a freezing night in Idaho Falls, it can feel overwhelming. As residents of Bonneville County know, our cold semi-arid climate means winter temperatures can drop well below freezing, and being without heat is not just uncomfortable; it's unsafe. Thankfully, there are several immediate steps you can take to minimize inconvenience and maintain safety until help arrives.
The first thing to check if your furnace stops working is the thermostat. Make sure it's set to 'heat' and the temperature is higher than the current indoor temperature. If your furnace still doesn't operate, try turning it off, waiting a few moments, and then turning it back on. If this doesn’t resolve the issue, it might be time to consider troubleshooting more serious problems. As a heating and air conditioning expert in the Idaho Falls area, I’ve seen the importance of understanding your system's basics.
Common Causes of Furnace Failure
There can be numerous reasons your furnace stops working. Here are some common issues to consider: 1. Power Issues: Check the circuit breaker. A tripped breaker can cut power to your unit. 2. Thermostat Malfunctions: If the thermostat is malfunctioning, it may not communicate properly with the furnace. 3. Dirty Filters: Clogged air filters can strain your furnace, leading to overheating and possible shutdown. 4. Pilot Light Problems: If your furnace has a pilot light, check that it’s lit. If it’s out, follow the manufacturer’s instructions to relight it safely. 5. Mechanical Failures: Age or wear and tear can cause parts to fail. Most furnaces last between 15-30 years, depending on maintenance.
If your furnace isn't operating correctly, it might be time to call in an expert. At Idaho Falls Heating & Air, we specialize in Furnace & Air Conditioner Repair and can quickly get your system back up and running, especially in the cold winters of Downtown Idaho Falls. In the meantime, keeping your space warm is crucial.
Keeping Warm Until Help Arrives
While waiting for a technician, here are some strategies to keep your home warm: - Seal Drafts: Check windows and doors for drafts and seal them with weather stripping or blankets. - Use Space Heaters: If you have space heaters, use them wisely, ensuring safety precautions are in place, such as keeping them away from flammable objects. - Wear Layers: Dress warmly with multiple layers of clothing, including socks and hats, to retain body heat. - Stay in One Room: To conserve warmth, gather in one room, ideally the one that receives the most sun during the day. - Cook or Bake: When safe, using the oven can also help heat the space temporarily – just remember to never leave it unattended.
Remember that if you find yourself frequently experiencing issues with your furnace, it may not be a short-term fix you need, but perhaps a full evaluation of your system. Regular maintenance can prolong the life of your unit and ensure it operates efficiently, which is crucial given Idaho Falls's freezing winters. You can keep your heating system in good condition by scheduling HVAC System Maintenance annually.
