Not all self rinsing cleaner are the same . The ones that are a brighter green in color seem to work a little better as far as clinging to the coil . The clingy is what I look for ,that is what emulsifies the dirt to really get it out. I use it almost full strength so it leaves an actual "I just got my coil cleaned " smell which is ok and safe for the H/O. I also get the one that is USDA approved for use in meat packing plant or whatever the bottle says. Remember though , this stuff will keep a clean coil clean .If you got one that has grown stuff I would go foamy cleaner which is hard to work with indoors and dangerous ,or I would pull it and wash it garden hose style with foamy cleaner in an outdoor enviroment. But to answer your question ,yes the self rinsing stuff is a great time saver. I use it on all my already properly clean coils. IF you think about it you could spray it on a heat pump in winter and the defrost cycle would rinse it .Or at least I think it would

Do you believe that on a clean coil simply applying self rinsing coil cleaner will be sufficient to maintain a clean coil? I don't get to use it often and was curious if it's really that good, because if it is, it seems like a good time saver on those bi-annual maintenance agreements.

Shoot a video of that please so I can show to the techs. I'll put it in the what not to do section or homeowners that spend more trying to save a buck lol.

Speechless... really I am. Good luck with that.

You are going to spray down a coil in an attic with a water hose?

Normally we take the coil outside and pressure wash it.

And if this is "Tech to Tech", why are HO's here? (Home Owners)

i have a carrier 3 ton air handler in my attic and cant figure out how to clean the coil. there is no access what so ever. the coil is actually in the air handler. i think its a 3 year old system.
