hi all,
i just visited manila a few days ago and have found out the follwoing:
1. that some airconditioning service and repair shops use the wrong
lubricant; polyol ester (POE) is used instead of polyalkyl glycol (PAG)
for 134a systems or retrofitted systems from R12 to R134a systems,
2. some shops use aircondtioning compressor for vacuuming the project
car's system instead of a vacuum pump ( compressors do NOT pull
complete or near complete vacuum of 29.8 inches of mercury (inHg)
3. that some shops use the same manifold gauges for R12 systems and
R 134a systems-causing cross contamination of refrigerant and
lubricant
4. that supposedly retrofitted systems are not fitted with the quick
disconnect fittings for R134a systems
5. that supposedly retrofitted systems are not using nitrile o-rings but
are using butyl or neoprene o-rings. nitrile o-rings are green
6. that most shops if not all (haven't found one) use an electronic leak
detector and rely on soapy water and disasembling the system to find
leaks.
7. that most shops are irresponsible in disposing spent or recyclable
refrigerant and making it disperse into the atmosphere and reducing
our ozone layer causing more and more skin cancer victims.
we need to retrain, enforce and limit pollution at the shop level.

balik sa topic , yes you're absolutely right there are lots of things to be corrected in phils when it comes to A/C service.
Buhay na buhay ang BGC this evening. Bukas halos lahat ng restaurants. Sabi pa nung isang cashier...
