Introduction: Spotting the REAL Problem -- Common Air Conditioning Repairs Carrollton TX

If you’ve noticed water dripping from the eve of your house and creating a rust spot on the siding, gutter, or brick, it’s more than just an eyesore. This is one of the most common signs we see as HVAC professionals in Carrollton and Farmers Branch (CFB), TX — and it almost always points to a clogged AC condensation drain line.

The good news? With the right know-how, you can often solve this problem before it causes major damage to your home.

Why Water Dripping from the Eve Is a Red Flag

Your air conditioner pulls humidity out of the air and sends that water through a small PVC drain line. Normally, that water drains safely into a plumbing line under your sink or bathtub. But when the line gets clogged, the overflow can back up and eventually spill out of your emergency drain line, which usually exits through the eaves of your home.

That’s why you’re seeing:

Water dripping down your siding or brick
Orange or brown rust streaks forming
Possible mold or algae growth near the drip

The Risks of Ignoring the Drip

A small drip might not look serious, but in North Texas heat it can escalate quickly:

Rust damage to metal siding, flashing, or gutters
Wood rot if water hits trim or soffits
Indoor leaks if both the primary and secondary drain lines back up
Foundation Issues if left untouched for years
Costly repairs from water damage or AC shutdowns

DIY Fixes for a Clogged AC Condensate Drain Line

Before calling in a pro, here are a few safe troubleshooting steps homeowners in Carrollton and CFB can try:

1. Tap or Vibrate the Drain Line

Sometimes a light buildup of algae or debris can be loosened by gently tapping the PVC pipe near the unit.

2. Use Compressed Air

If tapping doesn’t clear it, try blowing compressed air through the drain pipe. This can dislodge blockages and restore flow.

⚠️ Pro Tip: Make sure you know where your drain ties in. In many North Texas homes, the AC drain connects under a kitchen sink or bathtub. Always cover the drain opening before blowing air, or you could create a messy water spray inside.

3. Flush with Vinegar

Pouring a small amount of distilled white vinegar into the line can help prevent algae growth and future clogs.
