Biodegradable HVAC and Air Conditioner Coil Cleaner Foam Aerosol Spray, No Rinse, 19 fl. oz, AHCC-19 by Diversitech

I clean my inside coils twice a year. Spring and fall. This stuff works great. Keeps the unit efficient, and keeps the air smelling clean and fresh. Easy to use. Just remove your air filter, and front panel, spray and forget. It foams extremely well. Removed dirt and even mold.

Breakdown oils effectively, fresh scent, cleans wells, usually all on the first use. Paid 36 for 3 cans which was a great value.

Did as advertised, easy to use, would recommend this product

Love this product, keeps my Coils clean in the dusty area we live in , its Texas Yeee Hawww

This is the only coil cleaner I will use from now on. No harsh chemical smell. Foams thickly and does a good job cleaning the coil.

Had a ridiculous amount of buildup on the evaporator coils in my internal AC unit. The buildup was that greasy, black sticky gunk reinforced with fine dog hair that had escaped my plenum air filters. Bought one can of this foaming cleaner per side of the A-frame and applied liberally, first on the top-side (which was clean, but the hope was to have it flow through and loosen the gunk from the bottom), let it sit for about fifteen minutes. Then went back and sprayed the underside of the coils, using about half the can per side. Let sit for about fifteen minutes and came back to a noticeably cleaner set of coils. Repeated this process and saw a huge difference. I would call this foamer very effective, easy to use, and a good value for the price. Do note: You will want to use eye protection and wear sleeves when you apply this foam. It does burn a bit when it hits your skin, it is irritating if you breathe it in (so a respirator or good quality mask isn't a bad idea), and you'll want to consider gloves. You DO NOT want to get this in your eyes. Also, make sure you have a gallon or so of vinegar on standby. The gunk that melts/falls off will get collected and condensate water will flush it down your drain line. You won't want it to clog your line, so flushing it with vinegar during and shortly after the process is a good idea.

It work pretty good did the job.

The product didn't dispense very well. Doesn't seem like the right nozzle for the job. It would also be better if the can dispensed at any angle. I believe the cleaning agent worked but it was not easy to get it where you wanted it .

Came broken and without nozzle , no way to get a refund or re purchase
