Inverter Type AC in Pakistan (Inverter/Non Inverter Dedicated Discussion)

[anc]

Sir jee have you found a proper installer with vacuum pump in ISB/RWP

[HellsGuardian]

No proper teams in Islamabad unfortunately.

[crossfirex]

I am interested in buying 2 ACs for rooms of around 16x14ft size
Which cheapest and best DC inverter should I buy? How is ur experience with Candy and Changhong Ruba? My AC technician is totally against inverter ACs but after insisting and asking many times he suggested to get the cheapest one available in market

I live near sea in karachi so any special brand to look for? Should i get 1 ton or 1.5 tons. Both my present acs are 1ton and performing perfectly in these rooms since around 9yrs. But technician recommending 1.5ton else he says I would not be able to utilize INVERTER mode for which i am spending this money

go for inverter.. 1 ton should be fine, will take bit more time in initial cool down. later on both will perform same, got this chart from a tcl website, 1.5 can be considered but 1 ton isn't an issue either, rest, upto you, you want 1.5 or 1, pick accordingly

(3.5 kw= 1 ton)
(5.2 kw=1.5 ton)

This pic is totally against the concepts of most of the AC guys and correction room size is 17.6ft x 11.75ft
And just got haier opinion in below picture through daraz. So I have to go for 1.5ton. So how is Changhong ruba sdh-18sw pro?

yes, because ac guys don't even understand that a term "cooling load" exists

And just got haier opinion in below picture through daraz. So I have to go for 1.5ton. So how is Changhong ruba sdh-18sw pro?

i would say, consider haier candy, never experienced chanhong ruba so can't say anything about it

I am using haier good performance....
But chanhong ruba is not very much reliable...
Know many people who are not satisfied beacuse of it's durability...

Bro nowadays AC guys say no AC is reliable specially inverter ones may last 2-3yrs before defect. The good thing I liked about Changhong Ruba guys is that when i called their helpline and told them that i live near sea side. They clearly told that none of our inverter series will survive for more than 1.5-2yrs and there are likely chances of PCB fault (same thing that my technician said). Called general helpline they simply said that our AC have not yet reported any problem near sea side. But this thing is quite true but jub tak jis cheez ki zindagi hai tou hai. So keeping in view their honesty, my technician recommendation to buy cheapest inverter AC (as all of them develop fault much earlier then non inverter ac) and some good reviews about Changhong Ruba i am very much serious in buying it within few days. If anyone have some argument please do share. Same honesty was experienced by SIMTEK guys for pure sine wave UPS regarding proximity of sea but i still bought and installed it at a place that has minimum exposure to humidity and by the grace of Almighty it’s proving itself. So honesty is rare and it pays off

Can anyone please suggest me a reliable Inverter AC Service mechanic in Islamabad
Kindly share contact number if possible
Thanks

Thanks for sharing. I also value such things. I'm not using any product of changhong but I heard that their 'CHIQ' series ACs are good. If you see detail they mentioned compressor brand and even thickness of coil.
There is rusting issue in my area as well, I'm using haier from last two years.when I bought that, I disassembled the evaporator and applied epoxy on ubends, same was done on condenser. That is working for me, I alse shared pics in this thread at that time.

[crossfirex]

Please share those pics again. I also have that transparent paint i also applied on ubends but they survived only 2 years.. epoxy is same?

[umans]

New AC operation in progress. Applying epoxy on u bends to prevent corrosion. I'll do same for condenser as well. [image] [image] [image]

[umans]

Epoxy Resin. You can get it from any hardware store. Costed me 600, small packs are also available. There are two bottles you need to mix in equal proportion, it'll be thick like honey. Upon drying it'll become hard like glass. [image]

[umans]

Yups there is no substitute for proper installation. Thete is rust issue in my area so I'm coating exposed copper u bends and pipes with epoxy resin. This will prevent outer surface area. [image] [image]

What is normal repair cost of Inverter type AC? Like gas leakage, U bend replacement or welding etc?
I am thinking of Inverter type AC for the first time and many people saying that although it will save electricity but even if there is a simple leakage issue it will be very costly to repair and u cant even get rid of it as it has almost negligible resale value…

[helper_learner]

Leakage is not an issue whole inner unit is same except for the Ac control card aka PCB...

Its outer unit is different and is with controllable compressor speed / power...

Uband replacement or coil replacement or welding is not a big deal....

Main thing is the PCB which get fried normally due to not doing service (Ac got heated up and PCB give up) or voltages up and down or voltage spikes or bad frequency....

If any of these issues are present (power related) It is good to add voltage stabilizer with surge protection....

[crossfirex]

Yes PCB problem is a much bigger issue and my AC technician always make me afraid of it. Then i have to spend further money on stabilizer as well!! Previously i have been using my ACs without stablizers
But what I have heard is that pressure in coil is also higher than normal ACs and thats why ubends leak much earlier and welding cost is more than normal ac

[nfssaad]

you might want to check out pakref, they do corrosion protection coatings.

primarily i think its just lacquer / clear coat on all the electronics/copper.

but their rates are way too much.

[saqibhassan95]

Haier candy on sale
1 ton 61k
1.5 ton 75.5k
If someone is looking for cheap ac, do consider these

[helper_learner]

Is there voltage unstablity problem in your area.... If not then just add voltage spike protector
