Top 3 Major Dangers of Using an Outdated Heating System

Using an old heater poses various concerns, especially if it hasn’t had its yearly HVAC maintenance service. Knowing how to detect and handle these problems immediately may significantly influence your money and the safety of you and your family, and we highlight three dangers of operating an old furnace.

  • Leaks

Gas furnaces require a constant supply of natural gas to operate. Their gas pipes can deteriorate and leak over time, potentially lethal poisoning and destructive furnace explosions.

  • Fire dangers

Many older heaters lack enhanced safety measures in their newer equivalents, increasing the risk of a fire as the equipment ages.

  • Poisoning from carbon monoxide

Carbon monoxide poisoning is the most serious risk of operating an aging gas furnace. Carbon monoxide is a colorless and odorless gas that, even at tiny levels, can cause dizziness and nausea.
