That looks like dried up condensate. The insulated line needs to insulated all the way to the coil.

I'm going to agree. That looks like normal condensation that has evaporated. Freon is a gas. The dripping is under the water drain, and is in a catch pan. Did the repairman check to see if you had a Freon leak, since that is what he thought it was?

You can't see a freon leak, can you?

You can see oil residue left by a refrigerant leak.

So is it a freak leak? I know you cant see it but does the oil residue mean the leak is there. I had it inspected early but just decided to fill the freon up. The freon was empty when they inspected it.

If there was little or no refrigerant in the system AND the tubing or drip pan had an oily reside then yes, there is (or at least was) a leak at that point.

As said, residue from a refrigerant leak will be oily.

If your evaporator coil is before the fan as in the fan drawing through the coil you may have problems with your drain line as no trap can be seen in your pics.
The negative pressure in the fan cabinet can cause air to flow backwards in the drain line preventing water from draining.
Also, during days of extremely high humidity the moisture flowing across the coil can increase the negative pressure across it causing water leakage on these days.

If your coil is before the fan you could eliminate leaking by installing a trap.
