Foul Smells From Your Air Conditioner

[DavidB]

by David W. Bynon

That foul smell from your car's A/C is not only offensive, but it can also be bad for you. The air entering into your car passes over the A/C evaporator (the cooling element). When you operate your car's A/C, water condenses around the evaporator coils. The moisture on the evaporator makes it a magnet for air pollutants, including dust, dirt, grime, pollen, spores and germs. These pollutants form bacteria, dust mites, and fungi, which all add up to create the bad smell that often occurs in A/C systems.

Most luxury cars now offer filter canisters to scrub pollutants from the air entering the car, however, the smell may still remain. In any case, it's still a good idea to treat your car's A/C each year with a quality A/C and heating system cleaner. The product I prefer is Wurth A/C & Heating System Cleaner. Simply spray Wurth A/C & Heating System Cleaner into the exterior air intake vents and inside heat and A/C vents. It eliminates odors caused by bacteria, fungi, mildew and stagnant water.

A friend of mine is a very good mechanic at a local dealership. He told me he solves this problem by putting 50-50 mixture of bleach and water in spray bottle. With AC on regular so it brings in outside air, and fan on high, he sets the spray to a fine mist and puts a fog above windshield so it will be pulled in. He says the bleach won't hurt the paint, but kills all the nasties.
