panel clearance per NEC

[topgone]

Thought per code, for this size of swbd, we need either double clearance in front of swbd or one door from each end of it? The issue is second door cannot be added neither double clearance is met. The room is tight.

How wide is the air handler in front of the switchboard? As long as the free area at the side of the swbd front is bigger than 4 feet (at the side of the door opening), you might be able to haggle with the AHJ in your area. The purpose of setting working clearance rules is for workers to be able to extricate themselves from the room should untoward events happen.
