Air flow versus refrig charge

riverrunwest
12 years ago

I had a 2 ton system installed and they used a 12 inch return duct with a 20x20 filter rack. The filter would make alot of noise so I replaced the 12 inch with 16 inch. The noise is gone and it seems there is more air flow, do I really need to have the charge checked? The system is cooling well just curious.
