Car AC Diagnosis of Various Symptoms Dedicated Thread

Idea of general service+gas refill bro? If you don't mind can you PM me your cell # in case I need your guidance?

Thanks

I don't know but I give him 1000 for Labour rest I bring gas they charge 2k for gas but you can good gas for 700 or 1k

Car AC comps won't work. Vaccum pump is available but its too costly. A 4 CFM pump is worth 45,000.

Someone got 3cfm pump for 7k I guess

I Am Also Planning To Install Additional LINE Filter Drier.....As These Units Only Have Strainers But Not Proper FILTER....A Filter In-line Filter Will Prevent All Kind of Moisture Build-up Inside System And Make It Work LIKE CHAMP After Many Years..

It Cost Rs 450..Comes With Both Fitting Ends As Well As One Can Braze Them On Lines If They Want....!

all my home split A/C had them, I used to weld them in place, simple procedure honestly, just required a wet blanket on the drier while welding.

Secondly ser_gtr said a compressor will further contaminate the lines :0

Yes they will but he said that about normal compressors with 12000 BTU power they are under powered and often take long time to bring vacum down to 29mmhg with poor ports that start seeping air in as soon as vacum starts to go below 12 mmhg. I used was a 25000 BTU compressor with custom made proper ports. It hold vaccum for one hour and went to 29 mmhg in just 13 minutes. That's one hell of a thing.

Umm single stage?

yaara sab choro, 60000 BTU compressor use karo. zindagi aasaan banao..

j/k - buy a proper 2 stage vacuum pump, its a tool that pays for itself over time.

How much would I need and from where to get this gas and which one would suit best for my mehran? R12 maybe???
Also do I need to separately purchase the oil/liquid they put in with the gas or is that included in the service/labour charges???

Kindly give me your cell # I won't bug you THAT much I promise

[obsolete]

I recently put gas in my cultus... got a pipe replaced + leak check via pressure and vaccum. .. paid him 900 for this.... for the gas he was asking 2200 ... i have my own cylinder so i said no thanjs.... researched the market for original gas.... found out u can get original 134 feuron or genetron by buying the whole cylinder. .. but khuli gas.. they usually selll China cc gas..... i asked a guy that he can weigh hus cylinder and let me charge it in my car.... he can weigh the cylinder again and ill.pay for the gas consumed... after half an hour of behes and argument he agreed..... i borrowd a pipe from a another shop... and from empty to full, 600g gas was charged... so i paid him rs.600 (rs. 1000 per kg for genetron r134).... the ac works like a charm

Well I think it's serpentine condenser in mehran. If it came with original fittings then there is sticker out there otherwise you need to fill gas according to pressure charts. I think you can put r12 in your system. It's more efficient than 134 but if you put 134 you need to have good fan with condenser as it does not easily releases heat. Best if you install multi flow condenser and fill 134 gas. You have to buy oil otherwise they put oil as they please and they put oil in compressor only

You should put oil distributed everywhere condenser drier etc

I Heard For Someone That These Don't Work On Mini Splits Because They Have Strainers And Both Line On These Units Work Actually

As Suction Line.....But As I Know...It Only Have Strainers Which Is Nothing But A Small Net Type Grill Inside ...It Cost 45rs ...LOL

So This Idea Of Filter Drier Came In My Mind And When I DIG Into It...I Found It And Shopkeeper Agreed With Me That These Goes Into

Split UNIT And You Are NOt INSANE To Think Of It Here

I Am Looking For Now A Gas Welding Setup...A Propane Torch Comes Real Handy But I Won't Find It Here....! Oxy/ACY Cyl Set Is The Solution But Its Costly........Any Idea....

LOL... A 3CFM Single Stage Pump Will Be Good Enough.....

I wonder How Much A 48,000 BTU Unit Comprssor Weight And Who Will Make Vacuum Pump Out Of It

I have once used a 60000 BTU Bristol radial piston compressor for a vacuum pump, not bad, but 2 problems - firstly its a bit heavy and secondly its a bit bulky.

vacuum pump FTW..

very easily available, go ask any A/C supply shop.

Yes they do go into A/C linesets whether the unit is ducted central AC or mini split ductless.

Propane Torch Or Oxy/ACY Setup????

Propane Torch Is Handy And Easy To Carry And Very Good For Short Jobs....I Will Be Looking For It Along With Nitrogen.....!

[Xulfiqar]

propane

Not The Mention The Power You Need To Crank Up That Thing And Start It......It Will Require 3 Phase Connection For Sure And Sane Mind To Operate .....!

[SER_GTR]

propane

I Will Try It In Tariq Road Market ....Not Came Across It In Hashu Centre Saddar.....Or My Bad I Didn't Look Good....!

Its Easily Refillable Also??? Propane Butane Is Just A Form Of LPG I Guess....
