Strange smells from your heating system are urgent warnings that demand immediate attention. According to the National Fire Protection Association, heating equipment accounts for 14% of home fires each year, and many incidents are preceded by telltale odors that homeowners ignore. Whether it's the acrid bite of burning plastic or the sulfurous warning of a gas leak, your nose knows when danger lurks in your ductwork. Here are the smells that demand you schedule a heating repair in Mamaroneck, NY immediately:

What Do Different Heating Smells Actually Mean?
- Rotten eggs or sulfur indicates a natural gas leak requiring immediate evacuation and emergency response.
- Burning plastic or rubber suggests overheating components, melting insulation or electrical failures.
