25 Ambient Means You Are Hunting For 8-10 Degrees ...Pretty Much Attainable.....!

People In This World Use A/C On 25 B.t.w Even In Winters With Climate Control Or Small Duration

That is exactly what i am saying. We reach the same point no matter if we follow 1/3 rule or 30C less than ambient rule. This what my point is.

Anything less than 24-26C is a direct call for pneumonia.

No We Don't ...If We Go Minus 30 Degree Rule..... On Ambient 25 You Are Asking For -5 Degrees Whereas 1/3rd Is Like 8 Degrees...

As I Said Before....Its A General And Universal Thing......! Every System Have Its Own Efficiency Depending On Components So You Can Charge System As Per Specs And See What comes Out Of It....Its Not Gonna Be Same For All Systems

There Are Many Factors Involved......1/3rd Is Just A General idea To Know ....!

With Modern Climate Control...You Are As Good As Using Your Split A/C In Winters Also .....

As i said -30 is just merely a trick. Its not even a proper rule. Which ofcourse makes it not applicable in all situations bro

Brothers what kind of equipment do we need in these cases and their cost?
1- only for A/C check up and maintenance?
2- for gas refill and checkup and maintenance?

please mention cost of these equipment if one want to use it sparingly.

I would love to see an R134a unit that can provide a delta of 30C - Are you sure you are not confusing with ammonia systems that chill down to -40C..

[ahsanonline]

There are 1kg cans of r134a with the brand name 'freezer' (or 'freeze', i dont remember!) in the market. Has anyone used these? They look somewhat identical to honeywell, which shopkeepers also claim comes from china (doesn't everything these days??). The 'freezer' gas costs approx 700rs. for a can I think. Honeywell they're demanding 1100rs.

For A 1st Try If You Doubt You System's Capability Or Leak Doubts...Get that freezer....I Got It And It Doing Job Pretty Much Fine...

Honeywell Is Same Price As Here In KHI But You Need To Make Sure You R134a Won't Goes Into Vein Then You Recharge That

That FREEZER Brand Is Also Quiet Good And 1 KG Can Cost For Like 700-750....You Need To Get A Can Valve Also Which Will Cost Around 150/- Also Available In I Guess 300g Can ....

Get A Thermometer........Shove It In Your Car A/C Vent...Measure Temp....Day/Night

Get A Thermometer.......Stand In Shadowed Place In Day(Before Measuring Day/Night A/C Vent Temp).....Stand For 5-10min..Take Thermometer Temp...

POST All 4 Readings

On DIY Note........If You Have Blower In Home...Give You Car A/C Condenser A Nice Clean BLOW ...Then Wash It With Mind Pressure Water...This Will Also Make Diff If Your COndensor Is Chowked...Also Physically Inspect If FINS are Not Too Much Bent/Damaged

I wash the condenser weekly with running water. The fins are in amazing condition as the condenser was changed last year.

Good Enough Then....Take Temps And POST Here

You Might Be Just Running LOW On Refrigerant Or Anything Else....A Good Idea Of It Comes When You Connect High Low Side And Take Pressure Readings...But For That You Need Manifold Gauge Set / Couplers

For vaccum pump. Do you think old fridge compressors can do the job? They are pretty cheap almost 2000 from scrap yard.
