Temecula winters are mild but real — and a furnace that sat unused all summer needs attention before you rely on it. Here's your fall preparation checklist.
Temecula's winters don't get the respect they deserve. While we don't see the freezing temperatures of the Midwest or Northeast, overnight lows regularly drop into the 30s from December through February — cold enough to make a failing furnace genuinely uncomfortable, and cold enough to cause pipe damage if your heating system fails completely.
After sitting unused all summer, your furnace deserves a proper check before you depend on it. Here's what to do.
Change the Air Filter
If you haven't changed your filter since spring, do it now. A clogged filter restricts airflow, causes the furnace to overheat, and can trigger the high-limit switch — leaving you with no heat. Start the heating season with a fresh filter.
Test the System Before You Need It
Don't wait for the first cold night to find out if your furnace works. Turn it on during a mild day in October or November. Listen for unusual noises, check that warm air is coming from all vents, and verify that the thermostat is responding correctly. If something seems off, you have time to schedule a non-emergency repair.
Check Your Carbon Monoxide Detectors
CO detectors should be tested monthly and replaced every 5–7 years. Before heating season is a good time to check batteries and verify they're functioning. Install one on every floor of your home, including near sleeping areas.
Clear the Area Around Your Furnace
Furnaces need clearance for safe operation. Remove any storage, boxes, or flammable materials from within 3 feet of the unit. Check that the combustion air intake and exhaust vents (typically PVC pipes exiting the exterior wall on high-efficiency furnaces) are clear of debris, spider webs, and vegetation.
Schedule a Professional Tune-Up
An annual furnace tune-up before heating season is the most effective way to prevent mid-winter failures. Our technicians inspect the heat exchanger, burners, igniter, blower, and all safety controls — catching problems before they leave you without heat.
