Hitachi Home & Life Solutions India [Hhli] — AC is not cooling

Address:

Jhansi

I have purchased hitachi 1.5 ton 4 star inverter ac whose details given below & ac is under warranty.
Model no : - rsn 417 hcea
Indore unit no : - se190d92917
Outdoor unit no. :- 190d51793
Coolant r410

My ac is not cooling the room so on date 24 may 2020 i have filled a online complaint for “ no cooling issue “ against complaint no [protected] but not fully resolved & closed in your system.
Again i have filled a new complaint no [protected] again force close in systems without any resolution.
Again new complaint no [protected]

My room size where ac is installed is 90-100 square feet & ac is feeding the power with stabilizer in input voltage range 230 v +/- 10% of 1 phase 50 hz, whereas this ac is also able to cool 180-200 square feet room.

Service engineer came on 25 may 20 to check "no cooling issue" of my ac. He checked and said that this issue is due to leakage of refrigerant gas however he could not identify the leakage point at that time.

I suggested him to perform nitrogen test on my ac but he denied to perform the same on site (At my home) & asked me to send the ac to the service center.

Next day i have taken my ac to the service center and left it there. After 2 days service engineer called me & said that no leakage was found in your ac & give my ac to take back to my home.

Same day service engineer came & filled the refrigerant gas r410 but pressure of gas was low & current taken by compressor is not rated current which is 7.1 amp. & cooling is not coming at the desired temperature 16 degree when checked by service engineer by temperature meter at ambient temperature 35 degree centigrade.

Again after 2 days service engineer came to top up the gas refrigerant but unable to resolve the issue of cooling when set temperature is at 16 degree the service engineer temperature meter is showing 20 degree centigrade inside the indoor unit (Emitted air temp.) at ambient temp 33 degree centigrade. & compressor draw 3.5 ampere to 4.5 ampere current where as full capacity loading current of ac is 7.1 ampere.

Again on 10th june 2020 hitachi service engineer came & top up the refrigerant gas r410 now compressor is drawing full capacity current 7-8 ampere but my indoor ac unit unable to cool or emits air temperature less then 21 degree centigrade. & room temperature never goes below 29 degree centigrade resulting continuous running of compressor.

When i checked this temperature test with another 3 star 1.5 ton hitachi ac at set temperature of 16 degree (Lowest) of indoor unit emits inside temperature of air is reaching 6 to 7 degree centigrade.

Hence it is concluded that hitachi supplied defective / faulty unit of ac or its model rsn417hcea is defective which is never meet the desired temperature parameter & never chilling the room temperature below 28 degree centigrade.

If you want to cool the room at 16 deg c then the indoor unit emits the air temperature should be less than 8- 10 deg centigrade for some time then only it will meet the room temperature at 16 degree centigrade.

Hence you are requested to replace the faulty unit of my ac with new fresh unit of same model as my ac already under warranty & as already i have faced a lot of delay.
