Quick answer

If your AC shut off on its own, water is leaking from the indoor unit, or the drain pan under your attic system is full, the condensate drain line is likely clogged. Family First Comfort clears AC condensate drain lines across Fort Worth, Tarrant County, and the DFW Metroplex, cleans the drain pan, tests the float switch, and gives you one flat price before any work.

Your air conditioner pulls a lot of water out of the air during a humid North Texas summer. That water drips off the indoor coil into a drain pan and runs out through a small condensate drain line, usually PVC, to the outside or a nearby drain.

Over time, algae, slime, dust, and debris build up in that line until it clogs. When it does, water backs up into the pan. In many DFW homes the system sits in the attic, so an overflowing pan can mean a stained or soaked ceiling, unless a float switch shuts the AC off first.

We clear the line, clean the pan, and make sure the safety switch works, so the next clog doesn't turn into a ceiling repair.

Signs You Need Condensate Drain Cleaning

  • The AC shut off on its own and the thermostat went blank
  • Water in the secondary drain pan under the attic unit
  • Water dripping from the indoor unit or a stain on the ceiling below it
  • Water dripping from a pipe over a window (a secondary drain line)
  • A musty smell near the indoor unit or from the vents
  • No water coming out of the drain line outside on a hot day

What's Included

  • Clearing the condensate drain line from the indoor unit to where it exits
  • Flushing the line to confirm it drains freely
  • Cleaning the primary drain pan and checking the secondary (emergency) pan
  • Testing the float switch, and replacing a failed one
  • Included in every AC tune-up, or booked on its own any time
  • Checking the drain trap and the line's slope and connections
  • Checking for water damage or rust around the indoor unit

What Affects the Cost of Condensate Drain Cleaning

  • How clogged the line is and where the clog is
  • How easy the indoor unit and drain line are to reach in the attic or closet
  • Whether the float switch, drain pan, or a section of line needs replacing

We give you a clear price after diagnosing your specific situation, not a generic number before we've seen your system.

Condensate Drain Cleaning FAQs

Why did my AC shut off and my thermostat go blank?+

In many DFW homes, a float switch in the drain pan or drain line cuts power to the AC when the condensate drain backs up. It's protecting your ceiling. Clearing the drain line usually gets the system running again.

How often should an AC condensate drain line be cleaned?+

At least once a year, ideally during your spring AC tune-up. Homes with attic systems, long drain runs, or past clogs may need it more often.

Can I pour vinegar down my AC drain line?+

Many manufacturers suggest a small amount of plain vinegar at the drain access to slow algae growth. It won't clear a line that's already clogged, and you should never use bleach or harsh chemicals that can damage the pan or coil.

Is water in my secondary drain pan a problem?+

Yes. The secondary pan is a backup. Water in it means the primary drain is clogged or the main pan is leaking, so it's worth having the drain cleared before the backup overflows too.

Is condensate drain cleaning included in an AC tune-up?+

Yes. Every Family First Comfort AC tune-up includes clearing and flushing the condensate drain line and checking the drain pan and float switch. We also clear clogged drain lines as a separate service call any time the AC shuts off or starts leaking.
