did any one check to see if the coil is feeding 100%? such as a possible clogged distributor tube. I would want to compare pressures at coil versus outdoor unit. even though it may be airflow related don't assume it can't be a problem in side the coil, freon lines and so on. also verify the unit has the right compressor in it.

You're missing my point. I was replying to the idea of trying to determine if the OP has proper airflow by static pressure measurements. Unless his measurements are off the charts that won't give us the answer.
The whole idea of a variable speed ( also called "constant airflow motors") is to keep a constant amount of air flow under a wide range of static pressures. It is programmed to change the rpms needed to deliver the cfm selected. There is no manufacturers data that I know of that will tell you what CFM you will get under a particular static pressure with a variable speed motor. The only static pressure you might see in the literature if any will be a maximum allowed static pressure to where it can no longer maintain proper airflow. The only thing I've seen in writing so far has been from .8 to 1.0. tsp.

FREONRICK I know it is a copeland scroll compressor but that is all - also a coil problem is possible as the system has never worked. THPRE

Honestly, although this is goodman, there is way to much cluster'd crap for this to be goodmans fault.
Installed by a friend.
Installed in a mobile home.
Installed in a closet.
No AHRI match as of yet.
Installer can't figure it out.
No Tech rep in area.
Unusual static readings.
Some weird government test that can be cheated.
Homeowner trying to contact the manufacturer.
Opened the refrigerant circuit more times than alot of systems see in their lifetime.
Finally, 13 pages.
Your relief is not through goodman.
It is through the contractor.
Your coil is wrong for the heat pump. Sized fine for cooling, not for heating.
Your airflow is crap, compounding the issue.
Your contractor called goodman, goodman told him they won't touch this abortion, because their up to their rear in their own abortions that they've created.
Which is why goodman won't come out.
I think I mentioned this earlier, but the reason they don't deal with you, is because they don't want to, and they don't have to. They want to talk to their customer (the dealer), not the dealers customer (you).
The reason goodman can't help you, is because there is nothing wrong with their equipment. It's operating the way it should operate under the circumstances.
Call a different individual out who has experience with goodman equipment.
I've never heard of goodman refusing any warranty because a different contractor was used.
Most likely, you have no labor warranty with goodman anyways, you have a 1 year labor with the contractor.
OR for that matter, did anyone even register this equipment with goodman?"Better tell the sandman to stay away, because we're gonna be workin on this one all night."
"Dude, you need more than 2 wires to a condenser to run a 2 stage heatpump."
"Just get it done son."

You should take some time to look over the blower performance charts many manufacturers supply with their VS blower equipped units.
The charts are a little different than for standard blowers, because they have to give static pressure/CFM values for each of the motors airflow settings, so you have to be careful you are working off the correct part of the chart.
Here is an example of the Service Facts for an American Standard furnace, blower performance charts start on page 12.

My office manager (who doubles as my wife) said that old AHRI data disappears off the website after the equipment is deemed obsolete and is gone from inventory. So it's not surprising that we can't verify the number.

How many times must one fix something before it is fixed?
