No as shown the A coil in housed in the air handler unit ( the boxy part that you see inside the house). A coil produces lots of condensation from producing Cold radiator design unit, it also has drain system to drain the water down through you plumbing and out of the house. This Also need inpsected to prevent clogging and water dumping below the uinit where ever it located. The air handler fan pulls the cool air through the A coils and throuhout the house. So after 10 years of use I would inspect the A coils for corrosion also if you don't replace the air handler unit as John W and other suggested. I would get several estimates see if you getting resonable deal as suggested. They all cost about the same unless you have heat pump units.
