What is a heat exchanger, and why is it important?

A heat exchanger transfers heat from the burned fuel to the air that circulates throughout your home. It prevents dangerous gases from mixing with the heated air, ensuring that exhaust gases are vented safely outside while clean, heated air is distributed throughout your home. Regular inspection of your heat exchanger is vital for preventing CO leaks. Annual furnace maintenance is crucial for checking the condition of the heat exchanger and ensuring safe operation.
