Furnace keeps turning off in Los Angeles
A furnace that starts and then turns off repeatedly needs attention, but the symptom alone does not identify the cause. Use this guide to make safe observations and decide when to contact a furnace repair professional.
What repeated shutdowns can mean
Repeated shutdowns can have more than one explanation, and a qualified technician may need to inspect the system to determine what is happening. Avoid repeatedly resetting the furnace or taking apart HVAC equipment.
Safe checks you can make
Note whether the furnace turns off immediately or after running for a while, whether the thermostat still calls for heat, and whether the home receives any warm air. If a central filter is readily accessible, check whether it appears dirty; ENERGY STAR advises homeowners to inspect, clean, or change central air conditioner filters about once a month because dirty filters can raise energy use and damage equipment. Do not open electrical panels, work on gas components, dismantle the furnace, or enter an unsafe attic or crawlspace.
When to arrange furnace repair
Arrange a professional inspection if the furnace keeps shutting off, the home is not heating normally, or the problem returns after a basic thermostat or filter observation. Stop using the system and seek prompt professional help if you notice an unusual gas or burning smell, smoke, or another clear safety concern. Do not try to identify or repair the underlying fault yourself.
