Have you ever turned on your heat and noticed a strange smell?
As temperatures drop here in East Tennessee, it's a question we hear from homeowners. The good news? Not every unusual smell means something is wrong!
Here's how to tell the difference.
✅ WHAT'S NORMAL?
A mild, dusty or slightly burning smell when you first turn on your heat for the season is fairly common. Dust can settle on heating components during the warmer months. When your system starts heating again, that dust may burn off, creating a temporary smell.
This should typically fade within a short time.
⚠️ WHEN SHOULD YOU CALL SOMEONE?
Pay attention if you notice:
• A burning plastic or electrical smell
• A strong smell that doesn't go away
• Smoke coming from your vents or heating equipment
• Unusual noises or a system that isn't heating properly
If you notice these warning signs, turn off your heating system and have a professional inspect it. If there's smoke or a suspected fire, leave the home and call 911.
IMPORTANT: If you smell rotten eggs and suspect a natural gas leak, leave your home immediately and contact your gas provider or 911 from a safe location.
At Giles Heating & Air, we want our neighbors to know what's normal and when something needs attention. A little knowledge can go a long way toward keeping your family safe and comfortable this winter!
