What is the best way to ge rid of mold in only one A/c vent? it has been tested and found to be common.San An

Large vacant house has developed mold in one a/c vent in an upstairs bedroom. The mold has been tested and found to be common, the estimates to remediate are wide range and very expensive. The house was vacated in December and the mold showed up in mid January.When first detected I thought it was dirt from not changing the A/C filter, a few weeks later small spores were visible. We have had a very warm winter, Any suggestions and ideas would be appreciated. Thanks

I would have the A.C. set so you always have some air circulating through the system this way the moisture won't form or build and create a friendly environment for the mold. Without air movement it would be natural for the condensation to form with the big temperature variance hot and cold in your region of the country. Good luck
Reply:I would try spraying a solution of 50% bleach and 50% water in the duct and running the fan.





I am only guessing but it seems the bleach might get to the mold.





You must have a high moisture situation for the mold to survive.
Reply:If it is near the vent, you can clean by hand. For larger jobs in the duct work, there are companies with specialized equipment. Also, It may be cheaper to replace the ductwork. If I were to do it myself, I would elect to replace the ductwork, especially if it is only one section.
