"Don't buy!"

1.0 rating
Very Unsatisfied

I have had this unit for 5 years and it's nothing but a money pit. I have replaced the bearings, compressor and now a coil. Very expensive. Never again. Every time it's repaired the guy says I have never seen so many problems. Remember, don't buy.

"Don't buy Mitsubishi AC"

1.0 rating
Very Unsatisfied

I purchased a Mitsubishi(Heavy Ind) Inverter AC in June 2014 in Surat. Suddenly in August 2015, after 13 months, the AC stop working. I handed over the matter to the Surat authorized service center. They visited several times, took the inside unit and outside unit PCB & did a lot of research. Finally, after 45 days of long service time, they declared that the outer unit PCB is not working, hence you need to pay 14000 rupees for a new PCB. The irony is that I bought the AC for 50,000 thousand and they're asking 14,000 rupees for repairing charges which is 30% of the cost! Can you imagine any AC will give you such trouble ! My clear view is: 1) Very very poor service: Service is too lethargic, they never call you. Every time you have to follow up. They don't have a proper person to repair the AC. My AC took almost 45 days to repair & still I am waiting to start. They just gave me a discount on the PCB to 10700 rupees. For that I called their Delhi Office(International Aircon) Mr. Shailendra to resolve the matter. 2) Product is having very poor quality. Can you imagine, after paying 50000 rupees, after 13 months 15000 rupees is the repairing cost !! My Sharp AC is working since the last 6 years at home without any problem. 3) All the people in Mitsubishi heavy ind(International Aircon) look like a bunch of monkeys. They never listen, never see and never speak to the customer unless and until you shout. My recommendation: Don't buy a Mitsubishi Inverter AC.

"Never work corectly"

1.0 rating
Very Unsatisfied

Installed in 2006 by reputable ac company. Two years later, board burned down. Cost $450 to repair. Now expansion valve is stuck. I don't think I will fix. This product is piece of garbage. Do not recommend Mitsubishi to anyone. Save yourself a trouble, buy something else.
