Hello. I have a leaky evaporator coil (I can even hear the refrigerant hissing out of it). Could someone recommend a replacement model number. Seems like it would be risky trying to have someone repair it. I would like to be armed with what I want before the contractor comes out. I have a carrier infinity r-410a system from 2005. It was installed by the previous owner of the house, so I don't think I'm going to get any warranty help (please correct me if I am wrong about that).

Carrier condenser model 38TDB060311, evap coil model CD5AXA060024ABAA, furnace model 58MVP120-20.
