Water and Fire Risks in the Valleys

Summer heat in the San Fernando and San Gabriel valleys means air conditioners run hard, and a clogged condensate line can flood a hallway ceiling or a closet quietly. Check the drain line and the pan under an attic air handler before summer.

Neighborhoods against the foothills see wildfire smoke and, after a fire, mud and debris flows in heavy winter rain. Keep a plan for sandbags and know which way water runs off the slope behind you.
