Air Handler A Coil

Post by bernsjo » Sat Jun 16, 2012 4:41 pm

I have a 3 ton heat pump that recently was detected to have a R410 refrigerant leak in the air handler A coil. The A coil was replaced, however its design configuration was different which I do not understand and the manufacturer, Goodman cannot explain. The old A coil had two sets ( one on each side of the A coil) of three strings of copper refrigerant lines. The new A coil has two sets of four strings of aluminum refrigerant lines. Does the new A coil provide better cooling exchange than the old A coil, and will the aluminum lines corrode faster than the old copper tubing and is it a good match for my 3 ton AMANA condenser? Thank you, bernsjo

No, Goodman actually decided to make the new coil worse than the old one to ensure you would be an unhappy camper. Oh yea and aluminum dissolves as soon as water touches it to ensure proper leakage of freon.
