Previously I was in doubt about the quality of this AC. In the local market sellers are giving bad reviews about this. But but but... Wait listen me carefully... This product is amazing and it chilled my 20x20 feet room in 30 minutes. Go for it...

R32 Dual Inverter 2 Ton AC. Chills room so fast like jet speed.
Delivery: Received before date
Installation: Received same day on request by Onida. Rs.1600
Quality: Nice
Bought this for my mother to use in 200sqft hall. Room gets chilled within 5-8 minutes, ODU is so silent.
Happy with purchase.

Installation technicians are having poor knowledge and unskilled. They don't have proper tools to use.They made my newly home wall dirty, outdoor & indoor unit not fitting perfectly. They don't have proper tool for wall hole and drill bit for anchor bolt. Outer unit wall hung stand unevenly fitted and several place in my wall made hole and dirty finger prints. I sugest you, please hire skilled & knowledgeable technicians for installation

After ordering this 1ton ac i thought it would be not good enough for my 10x12 size room..But it cool my room within 10mins and i am using it on 26 all night it maintain the temp very smartly....Would recommend this product to everyone

Very good ac.best cooling
.and energy efficient...it consume 0.5 unit in one hour with 26* temprature. I am happy.thanks onida and flipkart..

This is my first AC. The best product from onida. Cooling is very good. Cool my room in ten minutes. Very energy efficiency. Noise is very low of indoor and outdoor unit. Also it looks very good. Installation is done in time and very very best. This is the best AC for middle class family. Onida AC is the one of the best company. Very very very Thanks to flipkart for giving delivery before time. I again thanks to flipkart and onida because they complete my dream.

Very nice product. Fast cooling, energy efficient, not noisy, good working. I am posting review after 2-3 electricity bills generating. It's very energy efficient. The bill hardly increased by 20-25 percent when summer was on full swing and air conditioner working was almost full day and night. So, this product is highly recommended to buy. Full Cooling time in hot condition is very less and it takes hardly 10-15 minutes for room cooling.

The unit cooling is good, I bought this with 3 years insurance plan.
Only glitch was the tubes were missing. Flipkart was good enough to sort it inspite brand being lazy -1 star is due to brand behavior though I am covered under insurance so no worries.
My choice was due to research on build quality, value for money and option to buy 3 years total warranty specially needed for cost due to avoid costs due to possible pcb malfunction in invertor ac.
1699 spent on insurance even covers one tim...
