When a system is open for repairs, is there a procedure for testing the condenser and evaporator for obstructions or fouling? For example, measuring how much pressure it takes to produce a certain flow rate? or measuring how much of a vacuum can be pulled with a given cfm pump? I'm thinking this might be possible given the the narrow passages of modern condensers. Except they seem to be so inexpensive that blind replacement of a condenser is more economical than testing first.
