My house has a rotten egg smell which is very prominent when the air conditioning is on. Please help identify the source and present a solution.

If you have a gas furnace you may have a gas leak. If its not a gas leak you will need to check your ducts return and supply. If your not sure what LP or natural gas smells like call your gas supplier to check it out ASAP!

Rotten egg smell does sound like leaking gas,, but also there is a problem with dirty,clogged-moldie evaporater coils that we call dirty sock syndrome, this just might be what you have, if its not leaking gas,have someone to clean-clean-clean the evap. Coil,part of the a/c unit
