Ac doesnt chills during daytime .. only chills during morning and nights

Quality of gas

Please survey the market you will find different rates for R134a ranging from 600/-RS to 1300/-RS per KG. I would request you to try cheaper and expensive refrigerant and then report back here which one work's better. I think it's something to do about purity of refrigerant.
That Multiflow condenser thing is also correct but i asked OP and he didn't mentioned which setup he is using.
Cultus from 2000-2006 came with Multiflow as well as sprentine condensers after that from 2007-2016 only sprentine condensers were available in Cultus from factory.
Rest I would agree to all of your other point's those are 100% spot on correct but i doubt that these arrogant AC technicians will do it that proper way ever and please tell me where to find these spal/bosch/gate item's i have searched the whole market in my city and I'm unable to find even one of these.. All junkies here are just keeping those so called (Japanese junk fan's) jaappaanniii pakhay.

For your kind information Hakim sb,I have done that swap already. But system was not performing at its best due to low quality gas. I changed the gas with original Honeywell and now AC is chilling in peak hours as well as AC load on engine has been reduced.

Vent temperatures with 'low quality' and 'Honeywell' gas? Ambient temperatures and humidity levels too, please

[sk_cooldayz]

I have a toyota passo 2007 model. Its AC had been working fine from 2011 till last Year. Last year and this year I am facing this issue of low AC cooling during day time and in congestions.

Got it checked with multiple AC workshops. They all say that pressure is fine. Compressor must have gone weak. Change the compressor with Toyota Duet compressor (price 6500 Rs) and change the condenser with china condensor (5000 Rs). Gas + labor (3500). AC gas spray valve 2000 rs.

I am not ready to accept their version. Is there a procedure to follow to see if compressor has really gone weak? Please tell me honest and qualified person in pindi/islamabad where i can get my car checked.

Thanks

bhai aap he in sahib ko samjhao.plz

I have tried to but i will not comment on it any more. Because if a person is not even ready to accept that there are different quality R134a refrigerants available in market then i would say he haven't surveyed the market and haven't used them himself. Simple as that. He should himself check the vent temperatures with both kind of refrigerants under same conditions only then he will get the point...
Rest as i stated above i do agree with all his other point's those are absolutely correct.

A very mature response ... much respect

[Massive_One]

Brother, which shop in Lahore would you recommend to get Cultus AC service / gas refilled + blah blah blah. Cuz our Cultus AC is also not performing well .

[hassantahir2]

I'm not from Lahore so can't comment on it. I think @RehanBhatti can guide you better about it as he is from Lahore.

[Massive_One]

Yes please, if anybody has personally experienced any specific technician who is expert in servicing car AC, kindly let me know guys.

[sayedgulhassan]

Ac gas affects the cooling bhai... I have personal experience with this

[maxpain007]

yr yeh kesay pata chalyga k konsi gas ki quality achi hai ???? sab wohe blue color k clyinder waali uae kerty hain ..... aor gas ki keemat bhi 3000 rs hai ... har bar check bhi ne ker sakta dalwa k ..

It is believed that non of the local mechanics have ever tried to botch your car AC.
Now, If the system's running pressure values are in acceptable range (not too high, nor too low) then its a clear indication that the compressor is doing its job quite well.

Not necessarily, but AC gas do escape very slowly through multiple weak points of the system like the schrader valves (service ports), O-rings seals etc, so topping up the refrigerant isn't a bad idea, however you need to measure exactly the pressures in relation with ambient temperature conditions.
You may share here both system's static (before operating the car AC) and running pressure values along with ambient temperature reading for analysis.

Changing system parts is highly inadvisable, before doing anything major it is suggested that to clean the condenser unit thoroughly (externally), however care must be taken not to damage/bent the fins. Also check the condenser fan, it should be rotating at optimum speed, for comparison check the fan of some other passo.

Honeywell, Linde and Arkema have good reputation in our local market...
But you never know what's inside the cylinder at AC technician shop because they get them refilled again and again. So the cylinder might be of some good company but refrigerant in that might be low quality one. It's all upto the person working on your car.
OR you can get the gas can's they are available in small quantities the best in them is Dupont (don't know if some better one is available or not but in my city i have found dupont refrigerant the best in can's) and that is available for roughly 800/-RS for 360 gram or so i don't remember the exact grams now there are many other brand's available but again we can't check if they are orignal or not. I have personally used KLEA gas can's and well they do ok i will say not exceptionally well but atleast better then what our local AC technicians charge. Those cost about 350-400/-RS for 250 gram refrigerant can.

These AC technicians mostly visit the wholesalers or big AC parts shops, there they negotiate and make a deal on any popular running item "aj kal ye brand buhut chal raha hay or is mein do numbri nahi or honeywell k counterfiet buhut agaye hein islye hm nahi rakhtay" among the different variety of referigerants. They fill their empty honewell gas cylinder by weight and put the cylinder back in its carton.

Each city has a bunch of reputable AC shops with a number of satisfied customers, they do charge more but generally their work is reliable. The must have proper tools and jigs like the recovery machine, a good set of gauges and other related items. So it is generally expected that such workshops may not be hesitant to invest in good quality referigerant gas.

[ZainMahdi]

I'm ready to accept your points, provided that you support them with empirical data.

I'm not disputing that there are different brands available in the market with varying prices. What I'm disputing is that using cheap 'China' R134a will significantly reduce cooling compared to DuPont etc.

Even one data point will convince me - just post vent temperatures for DuPont and cheap R134a - the control variables should be ambient temperature and humidity, on the same A/C setups, with the same (high) quality of workmanship.

If you don't have data right now, then further discussion on this point is moot.

[ZainMahdi]

Vent temperatures, please.

What is ur location in Lahore?? If cantt then let me know
