A category 1 natural gas furnace typically has an air temperature rise of how many degrees Fahrenheit?

A category 1 natural gas furnace typically operates with an air temperature rise between 60°F and 120°F. This range is significant because it reflects the effective temperature change that occurs as air is heated while passing through the furnace's heat exchanger.

In practical terms, when the furnace operates efficiently within this temperature rise range, it indicates proper combustion and heat exchange processes, which are crucial for comfort and energy efficiency in a heating system. The efficiency of a furnace can be gauged by its ability to maintain a balanced temperature rise; if the rise is consistently outside of this range, it may indicate potential issues such as blockages or equipment malfunctions, leading to inefficient heating or safety concerns.

Understanding the standard temperature rise range helps HVAC technicians diagnose furnace performance problems and ensure that systems are functioning optimally, providing warmth effectively while conserving energy.
