Cold nights and power outages are part of life on the North Coast. The best defense? A healthy heating system. At California Heating, we see more emergency furnace repair calls in Humboldt County during December than any other month. A quick tune-up today can save you from a cold holiday weekend later.
Why Furnaces Fail in Winter
- Dirty filters restrict airflow and overheat the exchanger.
- Condensate lines freeze or clog in damp garages.
- Old ignitors crack after years of cycling.
- Loose wiring fails after summer corrosion.
Most issues start small—then turn into no-heat emergencies just when the temperature drops below 40°F in Arcata or Eureka.
The California Heating Preventive Checklist
- Replace filters after heavy use.
- Inspect vents and outdoor terminations for blockages.
- Listen for rattles or delayed ignition sounds.
- Schedule annual maintenance before the next storm.
