Heating season in Los Angeles is short but real — and the first cold snap is when neglected furnaces fail. Twenty minutes in October prevents most of it.
What you can check yourself
- Replace the filter — a clogged filter is the #1 cause of poor airflow.
- Test the thermostat — switch to heat and confirm warm air within a few minutes.
- Clear the area — keep storage away from the furnace closet or attic unit.
- Listen — new rattles, booms, or squeals are early warnings.
- Check vents — open and unblocked in every room.
What belongs to a professional
Heat exchanger inspection, gas pressure and combustion checks, electrical connections, and safety controls need trained eyes and instruments. That's what a professional tune-up covers — and every Precise Air visit includes access to a free comprehensive home safety inspection.
