This is the second time in the past few weeks that a condenser has been diagnosed as “not leaking” and the first one was a misdiagnosis. This could be the default Honda response to A/C problems.
How did they determine that the condenser is not leaking? Were you charged a diagnostic fee for this result? If they are convinced that the condenser isn’t leaking, it would seem to be in their own best interest to locate the leak, assuming one may be present, given that the A/C is blowing warm air, since you would be on the hook for a potentially expensive repair that isn’t covered by a warranty. The whole idea of taking the car in was to find out what’s wrong and they told you what isn’t wrong.
Of course, if they’ve made a correct diagnosis, then you could end up spending 2 hours driving, plus diagnostic time at another service department, just to be told the same thing.
If you’ve been mostly satisfied with the service department at the local dealer, it might be worth the effort to go back and ask them a few questions.
