Winter in Arizona looks different depending on where you live. In Flagstaff, Prescott and Show Low, winters are truly cold. In the valley, the days are mild, but nights can still drop close to freezing. Either way, your furnace sits unused for most of the year and then is expected to work right away.
That burning smell
Many people notice a burning dust smell the first time the heat turns on. That is usually dust that settled on the furnace while it sat idle. A light smell that fades quickly is common. A strong smell that does not go away is a sign to turn the system off and call a professional.
Your fall checklist
- Replace your air filter before the first cold night.
- Clear storage boxes and clutter away from the furnace.
- Test the heat early, on a mild day, so you are not surprised later.
- Open and clear the vents in every room.
- Test your carbon monoxide alarms and replace their batteries.
- Book furnace cleaning in early fall.
Why cleaning helps
Dust on the burner area and blower makes your furnace work harder. A cleaning removes that buildup so the system can run the way it was designed to. If you also have a fireplace, fall is a good time for chimney cleaning too.
A note on safety
Gas furnaces must vent their exhaust safely outside. Keep working carbon monoxide alarms near sleeping areas, and if an alarm sounds, leave the home and call 911.
