Bubbles in the receiver dryer

[alwayz_yummy]

there should be a very little-miniscule amount of bubbles you can see even if the ac is on.. wheen you see its totally clear, its might be an indication of too much freon in the system.

but when the bubles dont stop, means lesser freon on the system, might be a leak somewher--hanapin mo yung malangis..

when the glass is so dirty, time to clean and replace the reciever/drier and the expansion valves.. and have your condensers, evaporators, solenoid valves, lines and commpressor undergo general flushing...

"but when the bubles dont stop, means lesser freon on the system"

true only for R12 system not with the R134A system, yan ang reason why most R134A receiver/drier ay walang sight glass

My R134A drier has a sight glass.... minsan may bubbles, minsan wala...

...pero di talaga dapat basis yung bubbles lang 'coz pwedeng overcharged na yung refrigerant, pero may bubbles pa rin... The pressure has to be checked on both high and low pressure sides talaga. Pwede kasing loose compression na yung compressor, or pwedeng yung expansion valve ay kailangan nang palitan...

normal lang ang bubbles. pressure naman ang tinitingnan sa linya ng A/C, hindi ang bubbles
