What is a duct test?
● Measure the air leakage of your ducts
● Find where you are leaking air
● See energy efficiencies throughout your home
● Help block contaminants from circulating
● High tech equipment is used to test your ducts

How is a duct test conducted?
Duct leakage testing is a quick and efficient way to find holes, leaks, and cracks in your system. It doesn’t take long, usually taking somewhere between 30 minutes to an hour depending on the size and complexity of your ducts. So, there’s no need to worry about disrupting your daily routines or being put out of your home.
To begin, your technician will seal off all your ducts except for your central vent. Then, a specially calibrated fan is installed to draw air out of your ducts. This is used in conjunction with a pressure sensor, measuring the exact volume of air being pulled through the leaks in your system.
By sealing your ducts, your technician can isolate where your leaks are located and give you expert advice on how you can go about sealing them as efficiently and affordable as possible. It’s that simple. Local Energy Audits takes the guesswork out of compliance by giving you the numbers you need to know, and we are certified to give you a seal of approval if you pass.
Don’t use temporary fixes
Unless you want temporary results, you need to make sure your ducts are equipped for frequent usage and won’t lead to problems down the road.
Clean your ducts before sealing them
Your HVAC equipment isn’t meant to handle excess dust and debris, leading to the need for repairs in the future.
Use mastic over tape
This gives you more protection and longevity in the integrity of your ductwork. Tape alone will break down over time, leading to repeat leakages. Mastic in combination with tape is a permanent solution.
Update your duct system
Unless you want temporary results, you need to make sure your ducts are equipped for frequent usage and won’t lead to problems down the road.
If you don’t find leaks, seal your ducts anyways
All ducts can benefit from additional reinforcements to prevent air leakage. By sealing your ducts now, you will improve the efficiency of your HVAC system and avoid repairs in the future.
