My vehicle's AC feels overloading engine after being on for 30 minutes or so, there's a whine sound when compressor turns on, and it goes away when compressor trips automatically. I noticed that it is putting more load on engine as now idle RPM is more than 1100, close to 1400 after initial 30 minutes run.
I think there's some clogging / blockage in system, or compressor/condenser needs replacement. I replaced compressor's noisy bearing few months ago myself, it ran without issue after that. Then there's condenser fan replacement recently. The last AC service done was bit less than 2 years ago.
I will try to take it to AC tech tomorrow, but I want to know following:
- Would it be a good idea to replace condenser + compressor?
- Is there's chance of getting new condenser of Pajero Mini 1995? or I've to look for kabli one?
- Any recommendations for expert AC tech in Karachi? Most people say to go to market near Tariq Road, but which workshop to trust?
