do you have the model number from the indoor coil itself?
Unfortunately yes....OR....many times the pan can be removed, cleaned, epoxy coating, sealed etc....once you find the leak you can attempt a repair.
In response to the ac tech....I am very skeptical. He would need to expose the coil to find part number and then call for availability. I am betting he is just trying to make a sale.
