Ok there are two different types for a HVAC system the one you read from
the EPA is typically installed on the downstream air to kill yes
biological, but if you can kill them the amount of the UV dose nm~cm2
the biological (anthrax 46,000 nm~cm2 ) are the highest in the range.
So all that would fall below that UV-C dose range as "allergens",
viruses and bacterias would be killed.
Now as far as "mold", "efficiency" and "allergens". Mold would call for
coil irradiation. As you know mold is always and continuously growing
on the coil because it is a perfect environment for mold to grow.
When the UV-C is applied to the face of the coil it will kill the mold,
thus having pressure drop across the coil which would equal
"efficiency". The motor for the unit would not have to work as hard
because there is not restriction on the coil (mold) on the air flow; so
you will accomplish extended life of the HVAC, energy saving becasue the
unit is not working as hard and no maintenance to clean the coil with
pressure washing which would not be as well. Plus, the fouled air would
not be as fouled.
Hope my explanation was helpful.

An air side pressure drop would lessen the air flow and reduce the amount of
work that the fan motor has to do.It would also reduce the load on the
compressor so how can you claim -

If the coil was all clogged up with mold, would there not be a
restriction on the air flow? Yes, there would so if the coil is no
longer clogged with mold then what I said would happen, no? Not to
mention you would no longer be spreading mold throughout a building.
And I forgot to mention before some HVAC manufactures sell this as a OEM
in their shipped units.

Funny thing, mold. Mold likes to grow in a dark environment. Mold likes to
be warm. Mold needs some organic material to breed upon. Mold is in the
air all around us. Mold spores are in the air around us all the time.
Funny things about air conditioning & refrigeration. The coil seems to run
cool compared to other environments. [40º F in air conditioning]. Mold
doesn't necessarily like cold. If the homeowner keeps up on the filters,
there's little organic material.
What happens is during the off cycle / winter months, mold can develop
provided there is some water available. Eventually, the water is gone, the
mold dies, but alias, it does foul the coil.
And yes UVC will prevent mold build up to begin with. But I believe a
standard incandescent light will too for a whole lot less $$$.
Don't get me wrong, I install UVC 's when the customer wants / needs them.

Ok, so if what you say is true what is the growth on a coil and why is
there a need to clean them. You can take a sample from the coil, have
it tested to prove that it is in fact mold, bacteria, etc.
One of the best food sources is human skin flakes, which are everywhere.
Yes, changing the filters will help but not solve. And you only
addressed the AC side of a HVAC what about heating? Always dark and
damp, just as mold likes.
Plus you wrong about the incandescent light, it is in the wrong spectrum
of light to kill what we are talking about.
