Before it gets cold, swap your air filter and turn your furnace on to make sure it actually fires up—don’t wait for the first freeze. Keep the area around the furnace clear, open all your vents, and check any exposed ductwork for loose joints. Make sure your thermostat works and has fresh batteries. Test your carbon monoxide detectors. If you’ve got a heat pump, clear leaves and debris from the outdoor unit. And last thing—schedule a tune-up. It’s the best way to catch problems before winter really hits.

You’ve already checked the thermostat, breaker, furnace switch, and filter.
Clicking, repeated attempts to ignite, or flame going out = pro job.
Leave the home immediately and call your gas company or emergency services—not an HVAC tech first.
Grinding, screeching, banging, rattling—these indicate failing motors, bearings, or blower issues.
System turns on and off every few minutes—often a deeper airflow or sensor issue.
Could be blower motor failure, duct blockage, or a safety shutdown.
Especially if it happens after the furnace has run for a bit.
A little frost is normal—a big ice block is not.
Leave immediately and call emergency services.
Especially metallic, ozone, or “overheating plastic” smells.
Often points to failing components or inefficient combustion.
Could be a clogged condensate system or frozen coil.
Usually more than a DIY fix.
Blinking lights or digital codes usually need proper diagnostics.
