RE: How do you measure system airflow?

So much of what we do requires either measuring or approximating airflow measurement on the entire system (over the evaporator coil) what method or methods do you use?

If you absolutely had to get a system air measurement within 5% of reality on every call what method would you use?

We use total external static pressure and Alnor flow hood.  For our new installs on gas furnaces we prep the furnace at the shop by  drilling test ports and plugs prior to install.
