AC Drain Line Cleaning

Stop the leak at its actual source: the drain line

Almost every AC water leak traces back to one thing: a blocked condensate drain line. We clear it completely and check the whole path, not just the visible drip.

Request this service AC Cleaning

Every AC unit produces condensate water that needs a clear path out through the drain line. Algae, dust, and debris build up inside that line over time, and once it's blocked, water has nowhere to go but back into your home.

Common Problems

Water pooling near the indoor unit

This is the clearest sign of a blocked drain line, since condensate that can't exit through the drain backs up and overflows.

Ceiling stains below a central or cassette unit

A blocked drain on hidden units can leak slowly into the ceiling before it becomes visible on the surface below.

A musty smell near the drain outlet

Algae and organic buildup inside the drain line create a distinct smell, especially noticeable near the outlet point.

The AC shuts off unexpectedly

Some systems have a safety switch that shuts the unit down when the drain pan overflows, protecting against water damage.

Signs You Need This Service

Any water pooling or dripping from the unit

Ceiling or wall staining beneath a hidden unit

A smell specifically near the drain outlet point

The unit shutting off on its own during use

Benefits

Clears the actual cause of leaks

Prevents water damage to ceilings & walls

Full condensate path checked, not just the drip

How it works

Leak source inspection

We trace the water back to confirm it's the drain line rather than a refrigerant or structural issue.

Drain line clearing

The condensate line is cleared using pressurized flushing to remove algae, dust, and debris along its full length.

Drain pan cleaning

The drain pan at the unit is cleaned to remove buildup that can quickly re-clog a freshly cleared line.

Flow test & leak check

Water is run through the system to confirm free flow and check that no leaking remains before we finish.

Equipment & Technology Used

Condensate line pressure flush kit

Clears algae and debris along the full length of the drain line without damaging the tubing.

Wet-vacuum drain extraction

Removes standing water and loosened debris directly during the clearing process.

Drain pan tablets

Approved treatment tablets that slow future algae buildup inside the drain pan after cleaning.

Moisture meter

Checks for hidden dampness in ceilings or walls near the unit to confirm no ongoing leak remains.

Frequently asked questions

In most cases yes, since a blocked drain line is the actual cause behind the majority of AC water leaks.

Yes, especially with central or cassette units where the leak can travel through the ceiling before becoming visible.

Algae, dust, and debris build up gradually inside the tube, eventually restricting or fully blocking water flow.

If a full drain pan was triggering a safety shutoff, clearing the line typically resolves it.

Every 6–12 months as part of regular maintenance, or immediately if you notice any leaking.
