Water – What should be cleaned or examined after an air conditioner drain pipe leak

air-conditioningdrainleakmoldwater

The other day, we found some water on the floor in our utility room. After some research and investigation, we discovered that the drain pipe from the central air unit was blocked. We were able to use a vacuum to unplug the drain line, and since then it has drained normally.

However in the meantime, we had some water on the floor, some in the blower compartment of the AC unit, and a lot of standing water in the condensation pan in the unit. We have had some bad experiences with water damage and mold in the past so I wanted to ask:

  • Do we need to be concerned about the water that leaked from the catch pan into the blower compartment?
  • Should we try to wash out/bleach the pan or anything? (It is very hard to get to!)
  • Should we have an HVAC tech come look at the unit/blower to check for damage?
  • Should we do anything special to prevent mold growth?
  • Is it worth it to have our ducts cleaned?

What else got wet besides the pan? Did the pan drain to the outside properly?

IF you got drywall or insulation water-logged, you will want to thoroughly dry those areas. It's not really worth it to clean out your ducts unless there is a lot of debris in them... The debris is what would mold, and with the constant movement of dry air over it, it's unlikely to stay moist enough long enough. Other than that, I don't think there is any necessary work to do besides making sure it doesn't happen again!
