You are talking about Car AC or domestic ACs?

You need some equipments for this job by the way.

car AC

Its quite easy infact..All u need is a cylinder of R134a ie AC refrigerant(gas) and a port attachment to connect to the low pressure side of ur AC..Start the car turn on the AC and luk into the clear glass window on the low or high lines and fill the gas until u stop seeing air bubbles!..This is not the recommended way as its a must to vacuum the AC system atleast half an hour then fill gas but it's an easy method u can do at home!

You Are Going To Overcharge System Badly If You Fill R134a By Watching Bubbles In Glass

You Need Proper Method To Charge

Measure Ambient...Proper Evacuation.... And Then Charge As Per PT Chart With LOW/HIGH Sides Connected .....

You Can Only Charge R134a Blindly If You Know Are Charging By Weight And Knows Exact Weight Of Gas Going Into System

But most of the reputable shops like Punjab Car A/C and Ahmed Car A/C use the same method to fill the gas. It means they aren't using proper procedure as well.

As i mentioned in my post that this is just a rough method and can definitely lead to overcharging and based on my personal experience even honda 3s dealerships use the same method of just connecting low side ports as most of the dealerships dont have refrigerant evacuation and storing machines instead the prefer to leak all ur gas and then charge u for filling it again!

Usually there is a whole market for this..a tank is quite expensive around 20k plus but can fill ac gas of ur car for a lot of years to come as a honda civic only takes 0.5kg of gas!

This method works for charging an R12 in AC system which we don't have now. Now we use r134a refrigerant. Changing it with that sight glass bubble method is a major FLOP and should not be used. Instead use PT chart method to charge or otherwise you'll have a very low performing AC in your car.

HONDA 3S If They Do It Like This Is Like A K2 Cigarette In Benson Box......'

However It Does NOt Need Evacuation Machine But Proper Tools To Perform

NO ..Proper Way Is To Hook Up Guges On Both LOw/Hi And Charge As Per Exact Weight If Known Or Using PT Chart As Per Ambient Temp
