AC Condensation Leak

In today’s house construction, many heating furnaces and air conditioning evaporator coils are installed in the attic. It frees up closet space in the house and it’s quieter when the heating/cooling is on.ac leak sacramento home inspection

When an air conditioning evaporator coil unit is installed in the attic (silver box in photo), a condensate overflow pan is typically installed under the unit. The condensate overflow pan is a safety device intended to prevent unwanted condensate leakage (water) from spilling onto floors and ceilings.

In the photo taken at a recent home inspection, there’s rust colored water in the overflow containment pan and the pan appears to be corroding… not a good sign.

If left unchecked, the pan will eventually rust through. This can lead to mold growth in the attic insulation or drywall ceiling; and/or ceiling water stains or leakage onto the floor.

You can count on a Pacific Coast Inspections, Inc. home inspector to see red (in the water containment pan). We recommend further review by a licensed HVAC contractor.
