Furnace blowing cold air — Los Angeles, California
When your furnace runs but only pushes cold or lukewarm air through the vents, the problem usually lies with the pilot light, flame sensor, gas valve, or a clogged air filter that triggers a safety shutdown. A certified HVAC technician can diagnose the root cause and restore heat, often in a single visit.
