Drain Line Cleaning

During the summer, when it’s humid, it’s normal for your AC to drain anywhere from 5-20 gallons of water per day. It’s completely normal for your AC to drain 5-20 gallons of water outside of your home (via the condensate drain pipe outside your home or office). It’s NOT normal for your AC to drain any amount of water inside your home or office (around your indoor AC unit on the floors or attic). Want a professional to assess your AC system to make sure everything is working properly?

If your AC is draining water outside It’s simply just doing its job. Your AC is responsible for cooling and dehumidifying your home or office. Humidity is the amount of water vapor in the air, so to dehumidify your home, your AC pulls the water out of humid air and drains that water outside.

Here’s how:

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)
