Clogged HVAC Condensation Line = Water Damage Waiting To Happen

When people think about their house having water damage, they usually picture the big stuff such as a pipe that has burst in the wall, a failed water heater, or a severe storm. One of the most common calls we get for indoor water damage comes from something totally silent, and hidden. That would be your HVAC condensation line. It sounds like a minor detail, but when this little pipe gets blocked, it can cause thousands in damages before you even realize there's a problem.

What is an HVAC Condensation Line?

Your air conditioner doesn't just cool down your house, it also draws humidity out of the air. Think about how a cold drink gets covered in sweat on a hot summer day. The exact same thing is happening inside your AC unit. All of that moisture drips off the cooling coils into a drain pan, and then flows out of your house through a small plastic PVC pipe. Usually, it just drips safely outside or into a floor drain.

How a Tiny Clog Causes Damages

Since that pipe is constantly carrying warm water all summer, it becomes a perfect breeding ground for algae, mold, and general slime. Along with household dust and pet dander that gets sucked into the system, a clog is bound to happen.

Once that pipe is blocked, the water has nowhere to go. Since your AC can easily pull several gallons of water a day out of the air, things can go downhill fast.

• The pan overflows: Within hours, the drain pan fills up and spills over.
• Ceilings and walls get soaked: If your AC is up in the attic, that water is coming down through your ceiling drywall and insulation. If it's in a hallway closet, it’s soaking through the flooring and baseboards.
• Mold begins to grow: Mold only needs about 24 to 48 hours to start growing on wet drywall. This is one reason why you need to act fast as soon as you suspect damages.

Red Flags to Watch Out For

Catching this early can minimize damages. Keep an eye out for these signs:

• The AC randomly shuts off: A lot of newer systems have a safety switch. If the pan starts filling up with water, it shuts the whole system down so it won't overflow. If your AC suddenly stops working, check that pan.
• Puddles around the unit: If you see water pooling around the base of your indoor AC unit, the line is already backed up.
• A musty smell: If your vents start smelling like a wet basement, you probably have standing water somewhere.
• Water stains: Spots on your ceiling or walls near where your AC sits are a dead giveaway.
