I'm having my installer manager drop by this Thursday to check out some minor issues with duct size to AC tonnage and noise due to airflow issues.
I bet he shows up with not one piece of electronic device.
Not an air flow meter to show intake at return grill (not an issue with me) nor
a decible meter (a big deal with me).
I mean...say someone "thinks" he is hearing more noise from one register than another. Wouldn't it be prudent for a top notch HVAC troubleshooter/manager of firm to carry a relatively quality Decible reader?
At least then, he could possibly say that one register area is not emitting any more db's than another.
PPL with $20,000 home theatre systems trying to remedy a noise problem.
Doesn't it behove a top notch HVAC contractor to show up with something in his kit besides his cell phone?
