I desperately need help. Living in Houston and my upstairs is hot and humid. I've had at least 4 A/C experts come to my house and nobody has been able to figure out why the system is not cooling upstairs.
I have 2 packaged units located on a flat roof of a 2 story townhome (no attic). As a result, the ductwork upstairs is sandwiched between the ceiling and the roof. I finally had someone figure out that we have an air leak in the ductwork located within the ceiling but nobody knows how to figure out where the leak is located since it is not visible. Does anyone know how to find leaks in ductwork that is not accessible?
I appreciate any help I can get.
