Commercial Heating/Air Conditioning rules of thumb

Hi.
The new building we are in has suffered from one side of the building being hotter in summer and cooler in winter. The building is one story. The center has offices and either side has open space which have been made into cubes.
There are thermostats on outside walls and inner walls of the central divider containing the offices.
The central part of the building has no hot air delivery, only cold air for summer. A common practice, I am told. The vents near external walls have both cold and hot delivery.
There is a main heat-pump delivery unit on roof and this kicks in during the early morning to 'jump' start the heat, if you will. After a period of time, when the temp has risen, the zone heaters kick in. These are electric and do have a fan to move the air to the ceiling delivery vents.
1) The delivery vents have a deflector to spread the heated air. If you are below them, you can feel that the hot air is not really getting sent out very well. A technique suggested is to modify the vents to just have honeycomb versus funky spreader metal gizmos.
2) One side of building is always colder.
3) Computer controlled... how does one know if this is setup correctly?
A general question: How can one critique a Heating/Air system to find out if all is done correctly?
Sorry for the weak technical description. Hoping clear enough.
Thanks. j

The only way to correct any problems is to have a local company out to check it for you. there is no way anyone can help you without actually seeing the layout and running some tests.
