Across Southern California, where furnaces sit idle for months at a time followed by sudden use, certain common furnace problems appear repeatedly. Residents throughout Los Angeles County experience no heat or blowing cold air, furnace short cycling, odd system noises, surprisingly elevated utility costs, failed pilot systems, and patchy heat delivery.

Routine visual inspections plus easy homeowner tasks usually eliminate a significant portion of these issues before they escalate into expensive crises. Knowing these common patterns helps you recognize warning signs quickly.
No heat or blowing cold air often frustrates residents first. This symptom most frequently results from thermostat malfunctions, failed ignition systems, blocked furnace filters, or engaged limit switches. In dusty areas like Glendale and Burbank, filters accumulate debris fast, drastically limiting air movement and causing the system to shut down for protection.
