I've found the ones with brass wand and tip do deliver more
pressure and flow.

Two gal sprayer won't fit in the bucket with the coil
cleaner.

Air compressor not suited for indoor boxes, the store people
don't much like that.

Not all sprayers are created equal and there are far more
cheapos than
well-built sprayers. Look for a Hudson brand, preferrably
with a
brass wand and brass sprayer tip. A 2 gallon will allow
for more
pressurized air, less frequent pumping, and more
versatility. Less
likely to find quality at HF than a hardware store.

I use an air blow gun to clean A/C fins, then follow up with
a garden
hose blast.
