1.5 ton inverter A/C: Which one to buy?

[SaurabhK]

finally got 1.5 PET for 40k plus installation.. However extra copper pipes of about 4 meters for both units cost me a bomb @700 rs per meter. hopefully i didnt get ripped off. Unit came with 10 feet per unit .

Congrats... U too managed to get it fr 40k then....great.
Where did u buy it from....?
Nop, u didn't get ripped off... That's the cost of the copper pipes.
I too needed extra around 2 meters... But used the ones from my old split ac including the power cables too. So I didn't have to spend a penny extra.
The installer himself suggested to use it n not buy extra.
Did u try getting it below 40k?

Hi any Idea on Sharp dealers in Chennai where i can get good prices

 

[sanchits]

Calling out all sharp and inverter AC owners... What settings /option to do u use or what are the optimum settings for fan speed, mode etc.
Sharp owners do u use auto fan speed or set a fixed speed ?
Also do u also set the Temp as auto too under mode, this is something new to me. This sets the temp as auto too and gives an adjustment of +/- 2 celcius.
Out of these settings which one is suggested n efficient as weell :-

Both fan n temp at auto.
keep the fan on auto n temp as desired.
Keep fan at a set speed n temp as desired.

Pls help me understand the settings n what do sharp owners suggest as their go to settings.my model is the x18PET without plasma cluster.

Auto Mode makes it too cold for me.. I normally have been using it at low fan speeds at 24 degrees. with 60% eco mode option.. 15 day usage in March ( nights only) have given me total electric bill of entire apartment of 1100 rs only. Its a Noiseless wonder.. However, i feel the real test would be in peak delhi heat of may June..

Thanks..but what exactly does Eco mode do, 60% or 80%. I mean how is it any different from not using it in terms of functioning or cooling ?

By the way, doe sth compressor ever shut down compeltley in this sinvertr model ?
I am asking this as I have felt that sometimes I feel little less cold n feel the temp rises after the temp coming down.
I don't know how to explain this, I am mostly setting the temp at 23-24 as of now with fan speed of 3 n use the air on ceiling swing option...don't know what its called.
After few minutes when the temp comes down I feel the air feels less colder the before n again it becomes cooler in a bit.
I thought it maintains the temp or am I missing something here or there is some malfunction with my AC or installation.
What do u think , should I call the sharp engineers n explain them this issue, my AC is brand new by the way.

I feel that since the temp in delhi is already quote low during late evenings and night n really hot summers have not set in yet, I feel setting the temp at 23/24 does cut off the compressor completely as the etemo inside might be going a bit lower then the set temp n the edofferenxe between outer n inner temp due to the pleasant weather is also causing the compressor to cut off for a tiny bit intermittently. I was going through an internaiotnal forum and read such quotes even for an inverter ACS . I am quoting it here few posts from that which kind of explain my issue as well.

"Inverters tend to go to the lowest possible speed, to remain in controll of the room.
Typically they may go one degree past the set point, and then if they are still about to overcool the room, they will switch off."

"Our Daikin inverters will shut the compressor down when inside temp drops too far below set temp, but the fan in the head continues to run. When temp rises the compressor will cut in.This will happen when there is not much variation between inside and outside temp."

I feel the 2nd point clearly explains the issue ei too am facing. Has anyone else here expereinceing the same with inverter ACS specifically sharp ?
Or I should get it checked ?

No need to get it checked.

These ACs are designed to operate in a band. Say 0 to 10% load, they would run like any other AC ie. on-off. Beyond 10% loading, the inverter would kick in and take over the compressor operations.

Even now it sometimes does ccompletely shut off the compressor when I keep at 24 c at night.
By the way, how does one know if the inverter tech is working perfectly or not ? I mean AC would be cooling or working perfectly n it might be a possibility that inverter tech is malfunctioned...how does one find out.

One issue is that I can smell foul air when the compressor shuts off...that humid air smell and as soon as its on....the smell goes away.

I just hope the AC is fine...n inverter tech is working well. I also want to ask are there any free AC servicrs included in the first year for sharp inverter ACS.

Would request other sharp inverter AC owners to pitch in.

you get 3 free services in the first year..
