How do you test an AC evaporator coil?
The most obvious sign of a dirty evaporator coil is an overall drop in system pressure. As long as you know what constitutes a normal pressure for your system, you should be able to tell if the current pressure is below that level. If it is, a dirty evaporator coil is probably your culprit.

Most people never see an air-conditioner evaporator core. Designers often tuck the evaporator core away, deep inside the dash. Like most auto parts, evaporator cores sometimes fail. When an evaporator core fails, the result is a loss of refrigerant and a lack of cooling. What is an evaporator core?
How can you tell if an evaporator core is leaking?
Because we cannot see the evaporator core, knowing if it is leaking can be difficult. We find most leaks with an electronic leak detector. With the system running, we insert the detector’s probe through the evaporator drain. Other times we must turn the system off and continue to check for several minutes to find the leak.
Which is the code for an EVAP leak?
