How does this unit improve heating and durability compared to a worn core?

• High-density fins increase surface area for faster heat exchange into the HVAC blower air stream.
• Aluminum construction resists typical corrosion and helps maintain a tight seal at joints.
• Precision dimensions reduce trimming or adjustment during installation.
