How much does it cost to clear or repair an AC drain line?

The low end is a simple clog near an accessible cleanout. Prices rise when the line runs through an attic or wall, is poorly sloped and keeps clogging, or has already overflowed and needs a new pan or float switch.

What is a float switch, and why does it shut off my AC?

A float switch is a small safety device in the drain pan or drain line. When water rises, a float lifts and cuts power to the system so the pan can't overflow. That's why a clogged drain often looks like a dead AC: the system stops, and on many setups the thermostat screen goes blank too. Our guide to an AC that won't turn on walks through the other safe checks.

If your AC shut off suddenly and you see water in the pan, the float switch is probably doing its job. Clearing the drain usually lets the system restart. If your air handler sits in the attic or above a finished room and doesn't have a float switch, adding one is cheap protection. Many attic systems also have a secondary pan underneath the unit as a second line of defence.

How do I clear a clogged AC drain myself?

Some clogs clear with a simple, safe approach:

1. Turn the system off at the thermostat and the breaker.
2. Find the outdoor end of the drain line, usually a PVC pipe near the outdoor unit or foundation.
3. Attach a wet/dry vacuum to the end, sealing around the pipe with your hand or tape, and run it for a few minutes.
4. Check the pan at the air handler. If it's draining, the clog is clear.
5. Restore power and set the thermostat to Cool.

Stop and call if water keeps rising, the pan is cracked or rusted through, or water has reached the ceiling or wiring.

When should I call a professional?

• The clog keeps coming back.
• The system shuts off again after you clear the line.
• Water has damaged a ceiling, wall or floor.
• The pan is rusted or cracked.
• The float switch doesn't seem to work.
• The system drains to a condensate pump that isn't running.

Repeated clogs often point to a line with too little slope, a missing trap, or a pan that's breaking down. A technician can fix the cause instead of just clearing the symptom.

How can I prevent drain line clogs?

• Regular maintenance: a tune-up includes a drain flush and a float switch test. See our guide to AC tune-up cost.
• Change filters regularly: dirt that passes a clogged filter ends up in the pan and line.
• Keep the outdoor drain end clear of mulch and soil.
• Ask about a float switch and secondary pan if your air handler is in the attic.

What does a condensate pump do?

When the air handler sits lower than the drain point, such as in some garages or utility rooms, a small pump pushes the water up and out. Pumps can fail or clog. If the system shuts off and the pump's reservoir is full, the pump is likely the issue. Replacement is a moderate job; installing a pump where none existed costs more because of the new drain routing.
