Seems odd to me but I suppose the climate is mild enough that a good working heat pump would be sufficient 90% or better of the time.
BTW, I suppose the system not having any backup heat would make it difficult for the system to stage it in
Also, I would ask them to show you exactly where the leak at the coil was. I have almost NEVER seen an indoor coil leak unless the coil was in a home with sulfur water. You mentioned the system was only 2 years old or so which makes me doubt the claim of a coil leak even more. My guess is, when they brazed the lines for the evaporator coil, they didn't wrap the metering device and most have a nut with a rubber O ring that will melt if you don't keep them protected while brazing.
