Duct Testing & Smoke Testing Services in Houston, TX

Precision Air Diagnostics by Flat‑Out Plumbing, HVAC & Restoration

When it comes to energy efficiency, comfort, and indoor air quality, your ductwork and building envelope play a critical role. At Flat‑Out Plumbing, HVAC & Restoration, we combine duct leakage testing and smoke testing with our blower door diagnostics to uncover the hidden air leaks that cost you money and comfort.

These advanced testing methods work together to give a complete picture of how air moves through your home—and where it’s escaping.

🔍 What Is Duct Testing?

Duct testing measures how much air is leaking from your HVAC ductwork. Using a calibrated fan and pressure sensor, we seal off your duct system and pressurize it to measure leakage rates.

❌ Common Issues Duct Testing Reveals:

• Disconnected or crushed duct runs
• Leaky seams and joints
• Gaps between registers and drywall
• Air loss into attics or crawl spaces
• Reduced system efficiency and uneven temperatures

⚠️ Duct Leaks Can Cause:

• Higher energy bills
• Increased humidity and condensation in attic or wall cavities
• Reduced airflow and hot/cold spots
• Mold or mildew growth from condensation buildup
• Poor indoor air quality due to pulling in dusty or polluted air

We use duct blaster equipment in compliance with International Energy Conservation Code (IECC) requirements to ensure your system meets air leakage standards.

💨 What Is Smoke Testing?

Smoke testing is used during a blower door test to visually detect air infiltration and exfiltration. As the blower door depressurizes your home, we release a safe, non‑toxic smoke near suspected leak points.

🔎 What Smoke Testing Identifies:

• Leaks around windows, doors, attic hatches, or plumbing penetrations
• Gaps in insulation or framing
• Leaky electrical outlets or light fixtures
• Faulty weatherstripping or sealants
• Envelope breaches not visible to the eye

The smoke is drawn through cracks, gaps, and unsealed areas, clearly showing where outside air is entering or conditioned air is escaping.
