Redesigned modern evaporator has 35% MORE PASSES, using three-circuits, instead of the original single-circuit design. This is a direct bolt-in replacement and requires no modification.As far as evaporators go, we highly suggest going with a good used evaporator over these new versions. What happens is this: These companies use more coils (35% more passes) which equals out to thinner metal. It has been our experience that these often fail within a few years. We suggest flushing and pressure...

Even though we stand behind these used units for 30 days, we still suggest that you pressure test them before installing as we all know what...
