Lennox 71L27 Heat Exchanger

The Lennox 71L27 Heat Exchanger (around 40 lbs) is a vital component designed specifically for Lennox gas furnaces (compatibility with some other brands might be possible, but verification is necessary). This heat exchanger is constructed from durable stainless steel to efficiently transfer heat. The 71L27 acts as a barrier between the furnace's hot combustion chamber and the cooler air circulating through your HVAC system. The stainless steel construction allows excellent heat transfer, warming the air that's then distributed throughout your home. High-quality stainless steel resists corrosion and ensures long-lasting performance within your furnace. This minimizes the risk of leaks and potential replacement needs. By efficiently transferring heat, the 71L27 helps your furnace operate at its peak, potentially reducing energy consumption and lowering your heating costs.
