I need to clean my evaporator coil on my Central HVAC (heat pump) unit. I have used a softbristle brush on my sweeper and there are still fuzzy stuff left up there. I am don't want to damage or bend my coils so what do you suggest I can use to get the rest off? Would Scrubbing Bubbles work OK or would that damage the coils? I know they sell a non rinse coil cleaner but I live in rural area and not sure where I could get it. Thought Scrubbing Bubbles might work and not hurt the system.

Is there an alternative to Rinse Free Coil Cleaner?

The rinse-free cleaner should only be used in warm weather; running the a/c actually provides the rinse action. Otherwise, the safest "cleaner" to use is hot water in a pump sprayer. Use caution not to wet the motor.

Sure, if by Scrubbing Bubbles you mean coil cleaner. Or if by coil you mean toilet. I wouldn't recommend it as it is not recommended for this use on the can. HVAC manufacturers' research and testing has established a link between airborne chemical elements and indoor coil failure. Cleaning products are rather high on the list of culprits.

Using any cleaner in Winter will require rinsing.

Cleanup

Yes, it is such. ;)
