Drain Line Cleaning

Below, we’ll explain both of these scenarios in more detail.

The AC condensation process:

• Step 1: Your AC pulls warm/humid air into your air handing indoor unit and that air blows over the evaporator coils.
• Step 2: The heat from that air is absorbed by the refrigerant and carried outside.
• Step 3: When the hot & humid air hits the indoor air handlers evaporator coils, the water in the air gathers on the coils and drips into a drain pan, located below the evaporator coils.
• Step 4: Once that water has gathered in the drain pan, it drains out of your home or office via the condensate drain line and is dumped outside using the condensate drain pipe.

So, if it’s humid out and you notice water pooling in your yard around the AC condensate drain, this is normal. All it means is that your AC is working hard to dehumidify your home.

If water is draining from your indoor AC unit…
…there is likely an issue with your AC system, like a:

• Rusted, cracked or damaged drain pan
• Clogged condensate drain line pipe (lack of semi annual maintenance or stubborn clog in the pipe)
• Frozen evaporator coil (which usually indicates a refrigerant leak)
• Damaged or clogged condensate pump (lack of semi annual maintenance & pump clean out)
• Improper pitch of the drain (after the AC unit leaks the base the unit sits on (if wood) starts to sag which leads to improper drain pipe pitch)
