Intertherm heat pump rusting

[wertach]

I have an Intertherm heat pump 2 years old and the coils are rusting on the ends (the steel part). Would it be OK to paint the ends with a rust preventive paint?

Don't expect it to help much, though. The other side of this steel "tube sheet"will be unpanitable and it is rusting also.

any evaporator coil,after about a years time is gonna start to show some rust,......it is just the nature of the beast!!!!!!

wertach... an honorable attempt at preventive maintenance..but you're wasting your time.

You'll never get a bond between the copper & galvanized - you can't get inside the coil struts & you certainly won't get to the back side of the coil you can't see.

Metal will rust, just like a new muffler on a car - you can't stop it- it's part of the dust to dust program.

It would be impossible to prevent the coils from rusting since this area has constant moisture even if painted the paint breakdown in a matter of weeks.

Thanks All!
