What is the typical operating temperature for a gas furnace?

The typical operating temperature for a gas furnace is usually in the range of 130°F to 160°F. This temperature range is ideal because it efficiently heats air while maintaining a balance between comfort and energy efficiency.

When the furnace operates within this range, it ensures that the system can effectively warm the living spaces without overshooting and causing excessive energy consumption or discomfort. Operating above this range can pose risks such as increased fuel consumption, higher system wear, and the possibility of overheating.

The other options presented reflect temperatures that are either too low or excessively high for standard residential gas furnaces. Temperatures below 130°F may not provide sufficient heat output for effective home heating, while those above 160°F could lead to operational issues and safety hazards. Hence, the range of 130°F to 160°F is the standard for a properly functioning gas furnace.
