Detailed Written Report
Something is wrong but nobody can find the problem
Your HVAC system checks out fine, your filters are clean, but rooms still do not get comfortable and your energy bills keep climbing. The answer is almost always hiding inside the ductwork.
AC works, rooms still hot
The unit checks out fine, but cool air never reaches the far rooms — the trouble is inside your ducts.
Bills that make no sense
High-efficiency system, sky-high bills — leaky ducts quietly waste 25-40% of your conditioned air.
Musty smells, more allergies
Mold, dust, and debris hiding in your ducts get pushed through every room each time the system runs.
Don't buy a system blind
Before spending $15K on a new unit, check that your ductwork can actually deliver the air it makes.
INSPECTION SERVICES
See Inside Your Ducts with Precision
We use professional diagnostic equipment — not guesswork — to map exactly what is happening inside your duct system and deliver actionable findings.
Camera & Video Duct Inspection
See What Is Really Inside
We insert a high-resolution camera into your ductwork and record everything — crushed sections, disconnected joints, mold growth, debris buildup, rodent damage, and construction leftovers. You see the footage and get a detailed written report with photos.
Duct Leakage & Pressure Testing
Quantify Exactly How Much Air You Lose
We seal your duct system and pressurize it with calibrated equipment to measure total leakage as a percentage of airflow. This tells you precisely how much conditioned air — and money — you are losing through joints, connections, and gaps.
Duct Air Quality Analysis
Test What You Are Breathing
We sample air from inside your ductwork and at your registers to test for mold spores, particulate levels, and allergens. Combined with visual inspection, this tells you exactly whether your ducts are making you sick.

FAQ
Questions We Hear Every Day
Practical answers about duct inspection services.
How to seal HVAC ducts properly means using mastic sealant — a brushable, fiberglass-reinforced compound — at every joint, seam, and collar connection, not standard duct tape, which fails within a few years. Foil-backed tape meeting UL 181 is acceptable for minor seams. Pressurized duct leakage testing before and after confirms the work actually reduced leakage. In NYC buildings, accessible ducts in mechanical rooms seal straightforwardly; ducts buried in walls require camera inspection to locate the worst leaks.
A duct inspection in an occupied apartment typically starts with a visual check of all accessible registers, grilles, and duct connections, followed by a camera scan through the supply and return trunk lines. Technicians use a pressure pan test or a blower-door assisted duct leakage test to quantify how much conditioned air is escaping before it reaches the rooms. The process is non-invasive and usually completed in two to four hours without moving furniture or opening walls.
Common signs that a duct system needs attention include rooms that are noticeably hotter or colder than the thermostat setting, high energy bills despite a functioning heating and cooling system, visible dust accumulation around supply registers, or a musty odor that follows air distribution patterns. In NYC co-ops and condos, uneven comfort complaints across units served by a shared air handler are a strong signal that duct leakage or blockage is redistributing airflow.
NYC's Energy Conservation Code and Local Law 97 compliance pathways increasingly require documented duct leakage testing for commercial renovation projects above certain square-footage thresholds. New commercial HVAC installations typically need a DOB permit and a licensed mechanical engineer's sign-off. For existing buildings seeking Local Law 97 carbon emission reductions, a verified duct inspection report can support the building's benchmarking submission and demonstrate system efficiency improvements.
Research consistently shows that leaky duct systems waste 20–30% of conditioned air before it reaches occupied rooms, forcing the heating and cooling equipment to run longer cycles to compensate. In a typical NYC brownstone conversion with older galvanized ductwork, leakage rates of 25–35% are not unusual. Sealing ducts identified during inspection commonly reduces heating and cooling energy use by 15–20%, often more in buildings where the ductwork runs through unconditioned basement or shaft spaces.
