Anything that will remove the musty/moldy/wet basement smell from the
heater/AC?  1994 Sentra.

Thanks,

Rick

It is probably caused by mold and mildew which has built up over time.
Often
the mold will plug the drain tubes where the air conditioner condensed water
should flow out to the ground.

If you can spray in a chemical to kill that fungi, chances are you can kill
the
smell.  The tubes need to be open so that drainage can take place.

One of the products that you might get your hand on is Consan Triple Action
20.  It is based on quaternary ammonium compounds that kill a broad spectrum
of germs, bacteria and fungi.  At use concentrations it shouldnt be
particularly
corrosive to skin or aluminum, but you wouldnt want to leave the concentrate
in contact with either.

A dilute spray of Lysol might also turn the trick.  Some people like the
odor,
others dont.  Same caveats about usage.

All the above should work to kill the fungus.   If you'll shut the a/c off
about a mile from home and let the evaporator dry out, the problem won't
reoccur.

There are commercial products for cleaning your car's a/c. Some are
reasonably priced and others are very expensive. Try your local
auto parts store or an a/c service shop.

Thanks for the replies.  I found this Interdynamics product called
"Pure Air" http://www.id-usa.com/product.asp?CID=9&PID=101 which I
think I'll try 1st, probably "relatively" cheap & available.  Agreed
about making sure the drain's clear, now all I gotta do is find the
damned thing ;-)

Doesnt say anything about the ingredients.  Might work, might not..but if
you can find it and it isnt too expensive, it's worth a try.

I've used that stuff, and I don't think it's as effective as Lysol, but
it smells better.

Do make sure the evaporator drain is clear before doing anything, though.

I havent looked at these carefully.  For any of them to work for the long
term, you have to get the mold killed out, and get the system draining.

Where moisture accumulates, things grow - sometimes nasty things.

(Personally, I believe humankind sprang from just such a humble
beginning;>).
