Duct Leakage Testing
At C2S Energy, we provide certified Duct Leakage Testing to help builders,
contractors, and homeowners verify that HVAC duct systems are properly
sealed and performing as intended.
What Is Duct Leakage Testing?
Duct leakage testing measures how much air is escaping from the duct system into unconditioned spaces like attics or crawlspaces.
Even small leaks can lead to significant energy waste, poor airflow, and higher utility bills. Using specialized equipment, we pressurize the duct system and calculate leakage levels based on airflow and pressure readings.

Duct Leakage Testing
for Code Compliance
At C2S Energy, our Duct Leakage Testing services are designed to ensure your HVAC system meets energy code requirements and performs efficiently.
Ductwork is often hidden behind walls, ceilings, or in unconditioned spaces like attics—making it easy for leaks to go unnoticed. Unfortunately, even minor leaks can cause major issues, including energy waste, uneven heating and cooling, and increased utility bills.
Our certified technicians use calibrated, industry-standard equipment to conduct precise tests that measure the amount of air escaping from your duct system.
This testing is required in many new construction and retrofit projects under IECC, Title 24, and other local building codes. We provide thorough inspections, clear documentation, and expert guidance to help you meet compliance and performance goals.
