Can I pour bleach down the line myself?

A vinegar or bleach flush between visits can help, but it won't clear a real clog — and some setups shouldn't get bleach. We clear the clog first, then show you a safe maintenance routine.

Will a clogged drain damage my home?

Yes — a backed-up line overflows into the pan, and when the pan overflows it goes into your ceiling or walls. A float switch helps, but clearing the line is the real fix.

AC Drain Line Cleaning in Houston, TX

Houston's humidity means your AC pulls gallons of water out of the air every day — and when the drain line clogs, that water backs up and overflows into your ceiling or walls. Pilo's clears clogged condensate lines fast. Call (713) 728-9776 for AC drain line cleaning.

How pricing works

Band-Aid

The minimum repair to get you running again right now.

We fix only the part that failed — the fastest, lowest-cost option to get your system back on today. It addresses the symptom, not the underlying wear that caused the failure, so it's best when you're planning to replace the system soon or need a short-term hold.

Smart Fix

The repair that solves the root cause, not just the symptom.

We replace the failed component plus the connected parts that are wearing out next, so you don't pay for a second visit in a few weeks. It costs more than a Band-Aid up front but lasts longer and protects the rest of the system.

Peace of Mind

Smart Fix plus a full tune-up, inspection, and maintenance plan.

Our most complete option — the Smart Fix repair, a full system tune-up and safety inspection, and enrollment in our maintenance plan so the repair stays protected and the next problem gets caught early. Best when you want the issue solved and prevented.

Every repair starts with one flat diagnostic fee, and that fee is credited 100% toward your completed repair — so you never pay twice for the same visit. Most common repairs (capacitors, contactors, drain clearages) run $150–$400; larger fixes like compressors or coils cost more. You'll see a flat-rate quote before any work starts.

Frequently asked questions

Houston humidity. Your AC pulls enough water out of the air to grow algae and slime inside the line, especially if the run is long or has a low spot. Regular flushes stop it.
