Flexible HVAC Duct
How can I confirm that my flexible HVAC Duct does or does not leak hot and/or cold air during it's operation?
The duct is 12 years old and is accessible in my attic.
I understand the HVAC professionals use some kind of a Temperature sensing tool.
Anyone know what it might be???

Look for holes and while the A/C is running check the connections at the main trunk and the boot. Feel around for cold air at the same.
