Gibson package unit blowing little air into house. Help!
So, I have been working on my central air unit. My problem this time is that there is little airflow coming through the vents in my house, all of them the same. I took the panel off by the blower and made sure everything was clean. I then noticed that while the panel is off, there is much more air flow through the house. I thought it could then be that there was something constricting the airflow in the return duct, but my husband checked it out and said nothing was there. What am I missing?

I'd say you have a clogged filter somewhere. Either that or a crushed return duct.
Friend of mine lived in a house for 5 years, never knew there was a filter in the unit that needed changing.
Have you looked at all the return grilles for a filter?

Yes, we have. The house sat vacant for 10 years before we started fixing it up again. The duct work was put in about 2 years ago when we first got the place, and the system has not been run, so as for right now there are no air filters. I was trying to get it working first before I went and picked some up.

where would the filter in the unit be located? I can't find it in the online manual.

A model number is required when we search for the manual.

I have found a few numbers on it, but I think the one you need is GR4GA-036K096C

Can you get to the dirty side of the evaporator coil? (item 34)
It is opposite the blower side of the evaporator coil.

Behind the fan? I'm trying to get in there, but it is proving quite difficult.

Looks like you have a small door in panel 9 that will let you see the dirty side of the coil.
Turn off power and clean it with some simple green and a water hose.
Home Depot has a nozzle like the Bullseye that can focus into a very small stream . I use the Bulls Eye from Johnstone but this one uses the same 3 ball bearing method for controlling the stream well enough to practically sign your name on a sheet of paper.

I always pop the top and the coil is always dirty.
I sometimes use a stick of pvc to prop it open if one is side sealed with tar or mastic.
Use a large trash bag to keep water off of the blower motor.
