I have 5 Panasonics. One of them is almost 10 years old. All are working great. Never gave any issues.

Have a look at Mitsubishi Heavy Industries acs. They have the smaller IDU as well as the bigger ones. Both of them have higher air flow rates and long throw. I wanted the larger IDU but settled for the smaller one because I wanted a 5 star inverter model which only comes as smaller IDU.

You have two options

1. Install a VRF unit with one ODU and 9 IDU. VRF are installed by Commercial/Industrial division and their competence and workmanship is far ahead of Home Division installers. Further VRF units use better pipes and fitting, so leaks are rare. Unlike domestic units, VRF units are designed for decades of use.

2. Get the splits assembled by local assemblers using old technology. These have minimal electronics and are quite rugged.As they are assembled and supplied locally maintenance and warranty should not be a problem. The only downside of old technology is power consumption, but you are not bothered much by it.

Hello folks,

I am on the lookout for a sub Rs.30k 1.0 ton inverter split ac. Which among Voltas, Godrej, Lloyd would be better w.r.t durability and service? Other brands seemed to be a little expensive when compared to the ones mentioned above.

Thanks in advance.

Not sure about Hitachi or Carrier, but LG does not have regular splits. They only sell inverter ACs. Voltas will surely have regular splits. Whatever you go for, make sure you take extended warranty coverage. Chemical fumes or for that matter even seaside air can cause problems with ACs coils and circuitry.

What is the reason that the chemical fumes won't affect a non-Inverter AC?
Asking because I have a problem with my washing machine because of the environment it's kept in & one of the mechanics suggested that a non-Inverter Washing machine wouldn't have the same problem. But I couldn't exactly understand the explanation he gave as to why.

Waste dump in the nearby drain by factory causes the fumes which damage copper. It will damage non inverter as well but since expected life of the AC will be 2 to 3 years, low cost of non inverter is better advised than inverter.

Cleaned and started all the ACs today. However hit a problem with a LG dual inverter 2T one which is exactly year old. Now then, it cools but the ODU is making noise like a tractor (no exaggeration). There is decent amount of condensation on the large pipe going into the ODU. This unit was serviced last by the ASP in November.

Now then, 0.9T Hitachi unit which has not been serviced by ASPs for the last 6 years is running fine, and the ODU is silent.


Now then, what could be the problem with the LG unit, or is there is known problem? when new the LG ODU was pin drop silent.

We also have a LG 2.0T Dual Inverter Unit. The ODU of our AC also heavily vibrates for first ten minutes or so only, post that it becomes pin drop silent. I have also noticed water droplets on the pipe connecting the ODU.

I would say observe the noise after 10-15 minutes of operation. I feel that it vibrates initially as the AC runs on full load for first few minutes. In our case, its a top floor room which gets really hot in the summers.

Under full load, the compressor tends to vibrate. The vibration is rendered innocuous by its rubber bush in the mount. But the rubber ages fast when the unit is placed directly under the hot sun. The vibration shakes the entire unit and the blower's fan blades might foul its enclosure causing the tractor noise.
Some manufacturers are notorious with flimsy metal shields while others like Voltas, O General make rigid frames. Heard this in cars too ?


Observe in close quarters. If the fan blades are running foul, attend to the problem asap. Or you will end up with a broken fan blade. This will trip the compressor periodically every few minutes.


Permanent solution is to see where it vibrates and renew the rubber bushes.

Condensation on the suction line is normal. Nothing to worry about.

The tractor like noise you describe needs attention, observation. More than the compressor, it could be something else. I have a Mitsubishi Inverter and it makes very little noise during start up and almost no noise while running.

Aircon experts, I beckon you all.. there is a need for another unit for the bedroom, we have a Panasonic HVAC which is still good, so far, albeit a bit noisy and a bit ineffective in chilling quickly, but it keeps the hall ventilated and warms up the hall during peak winters which is nice for the folks.

This time we need just a cooling unit as the room gets unbelievably stuffy at times, the need is for quality, quality and quality, i.e silent operation, effective cooling and maybe features like air purifier or plasmacluster ion if possible.

Price isn't an issue, as long as performance and reliability are equal to the high pricing.

Been using Daikin for more than 11 years in two of our bedrooms, 365 days a year. Very satisfied with them. Have a one year old Mitsubishi Heavy Industries 5 star ac for about a year now. It is awesome too. Is about 15-20% more pricey than most other models but I've been happy with its performance. I probably should have stuck with a 3 star and saved maybe 10k but nevertheless like the brand, performance and the product look and design.

We're all light sleepers, so I really dont want the aircon to be spitting and creaking at night.. how is the refinement of both and which is more silent?

Panasonic is a noisy one, but can live with it as it's in the hall. Also do they have some form of air purification/pollution filter tech?

Went for MHI for its fantastic throw of air. The 5 star does not have the distance of the 3 star but one can definitely feel the air across a 14 ft room. On full fan speed there is some sound but my BLDC fan is anyway louder. I like the refined looks of the MHI and it does have two extra strips of filter but not sure of its purification capability.
