the right cleaner for the A/C coils

[Rixey & Jeff]

It's my understanding that different foam cleaners are needed for the condensing and evaporative coils (we're getting ready to do our first maintenance cleaning since purchasing) Since the evaporative coils vent into the rig, I'm assuming the difference in cleaners has to do with odor or toxicity. If that's correct, will Simple Green coil cleaner fit the bill? It is non-toxic and biodegradable. If I'm wrong, then what differences am I looking for in ingredients? Another possibility is that I'm making this more complex than it needs to be

I'm sure there are products that will do the job, but I've never used any type of cleaner on my AC coils. I've only used a garden hose with a sprayer and sprayed them, getting rid of bugs that got trapped in them, and sometimes a leaf or two that's deteriorated.

I do the same thing with my automobile radiators, spray them down with a garden hose sprayer. More is not needed in my opinion.

If you have ever watched an HVAC service person service the cooling unit at your home, all they do is spray it with water from a garden hose. That's it. At most, they'll use a tool to straighten out bent up fin.

Thank you! That's very helpful (keep it simple)

I use the same two as Bob shows. They work well for cleaning up dried on bugs and stuff too. Water just doesn't seem to cut that.

I dont use any liquid ... I use my air hose at low psi and blow out the condenser coil..

The Evap area is where the gateway is tucked away at down just inside the duct ... I would not want liquid getting down into the wiring..

Since I pull my AC covers every spring and keep my inside return filters clean there is really no need for me to use any liquids to clean either coil area..

I also wipe down the components with a damp rag and check the fan motor bearings for evidence of too much play..

My unit is now 11 years old.. both AC units inside are as clean as day one.

YMMV
