AC Drain Line Clog in San Antonio, TX

An AC drain line clog in San Antonio, TX shows up as water where it should not be: a stain on the ceiling under an attic air handler, a puddle beside the furnace, or an AC that shuts itself off for no clear reason. Central air pulls gallons of water out of the air on a humid day, and all of it has to leave through a 3/4 inch PVC condensate line.

That line clogs with algae and slime that grows in the dark, damp pipe. Our crew clears it with a wet vac at the outdoor end or with nitrogen pressure from the inside, then flushes it and checks the trap. We also test the float switch or pan sensor that should shut the system down before water overflows. If yours never tripped, we'll find out why.

Attic units need a secondary drain pan under the air handler, and many older installs have a pan that is rusted through. We check it while we're up there.

A clogged drain that tripped the safety switch is a common reason for an AC not turning on. Call (866) 703-1217 when you see water.

Central AC Repair FAQs

Common questions about central AC repair

Questions we hear about AC Drain Line Clog in San Antonio, TX.

Talk to our crew
Why is my central AC running but not cooling the house?
The usual causes are a clogged filter, a dirty outdoor condenser coil, low refrigerant from a leak, or a failed capacitor that has stopped the outdoor unit while the indoor blower keeps running. Our crew measures the temperature split across the indoor coil to narrow it down before we quote anything.
Is it worth repairing an older R-22 system?
Sometimes. R-22 has not been produced or imported in the US since 2020, so any recharge uses reclaimed refrigerant at a high price. A small electrical repair on an R-22 unit can still make sense. A major leak or a failed compressor on one usually does not. We'll give you both numbers.
Why does my AC keep tripping the breaker?
Common causes are a compressor struggling to start because of a weak capacitor, a shorted fan motor, a compressor with a winding shorted to ground, or loose and overheated wiring. Resetting the breaker over and over can make it worse. Leave it off and call us.
How long does a central AC system usually last?
Many central air systems run 12 to 15 years with regular maintenance. Units near the coast, where salt air corrodes coils, and units in very long cooling seasons often wear out sooner. Age alone is not a reason to replace, but it factors into repair decisions.
Do you work on heat pumps and furnaces too?
Our focus is central air conditioning: split systems and packaged units, the outdoor condenser and the indoor coil and air handler. Call (866) 703-1217 and tell us what you have, and we'll let you know if it is a job for our crew.
