Gas Furnace (Heat Generation)
It creates heat by burning fuel. It delivers a fast, intensely warm blast of air (typically 110°F to 120°F at the vent), making it incredibly effective in freezing and sub-zero climates.

Heat Pump ( Heat Transfer)
It does not create heat. Instead, it uses electricity and refrigerant to absorb ambient heat from the outside air and move it indoors. Heat pumps are highly efficient in mild to moderate cold climates like California.
