Interesting??? I would love to have every unit I service setup in a lab with all the ports already put in..:)
You will never find a nice port inbetween the furnace and coil....
Your best bet is to find someone who can interpret the results as things in the field are never so cut and dried.
They are if you install the ports when the system is installed and commissioned, this allows you to benchmark the equipment and show the customer exactly how the equipment is performing. Some areas are now requiring third party benchmarking and eventually will be required on all jobs.
