Before employing more advanced techniques, a thorough visual inspection is crucial for duct leak detection. Start by checking the most accessible sections of your ductwork, such as those located in your attic, basement, or crawl space.

What to Look For During a Visual Inspection:

Gaps and holes: Look for any visible openings in the ductwork, however small.
Loose connections: Check for areas where duct sections are not properly sealed.
Damaged sections: Look for tears, punctures, or crushed areas in the ductwork.
Improper sealing: Examine the sealant around joints and connections for cracks or deterioration.
Signs of pests: Rodents or insects can cause significant damage to ductwork.

3. Using a Smoke Pen or Incense for Duct Leak Detection

A smoke pen or incense stick provides a simple and effective method for detecting smaller, less visible leaks. Simply light the smoke pen or incense and carefully introduce the smoke near the ductwork joints and seams.

Interpreting the Results:

Smoke escapes: If you see smoke escaping from any areas, you’ve identified a leak.
Smoke stays contained: If the smoke remains within the ductwork, the area is likely sealed properly.
Multiple tests: Perform this test in various areas of your ductwork to obtain comprehensive results.

Using a Professional Duct Leak Detection Kit:

Seal all accessible ductwork openings.
Introduce pressurized air into the system.
Monitor pressure fluctuations. Significant drops indicate leaks.
Use a manometer or digital gauge to measure precise pressure differentials.

This method is more precise than a visual inspection or smoke test, helping to pinpoint the exact location and severity of the leaks.

5. Professional Duct Leak Detection Services

If you’re uncomfortable performing DIY duct leak detection or seeking more comprehensive diagnosis, consider hiring a professional HVAC technician. Professionals utilize advanced equipment for accurate assessment and offer effective solutions for repair.

Choosing a Qualified HVAC Contractor:
