The gas never needs to be refilled or recharged unless it leaks. Then the cause of the leak needs to be cured.

Have been meaning to ask the general opinion of Whirlpool current devices. The look very smart!

Also wondering about two other makes, current T-BHP score:

Samsung: went down hill for a while. How is it now?

LG: if their support for AC is as good as for other devices (seems to be a pretty good experience overall) does that make LG worth buying?

This is probably called innovation !! AC can be used as Fridge to keep vegetables and vice versa !! lol:

:uncontrol I'm happy to say that the onion episode is closed!

Only fly in the ointment is that it is a R22 type AC. I was asking for a R32 or R410 and am particularly keen on Mitsubishi. My sister's place has a few of these machines and I just love the volume of air it throws out compared to the rest of the machines.

It seems like a no-brainer to wait for the next batch of Mitsubishi to arrive and go for a 1 ton from it. But just confirming, is R22 v R32/410 really such a big deal as it is made out. Especially with the non-availability of the refrigerant in the later years.

Any other maintenance tasks that I need to be aware of?

Yes it's a big deal. R410a has way more GWP as compared to R32 and is as well less efficient (internet) then R32. As long as you keep using R410a it is contributing more towards the GW which as per the current read on internet is more damaging.

So R32 is the best option. Mitsubishi has R32 but they are non-invertor AC.

My suggestion would be go for R32 for the environment reason as it would be priceless contribution. Just my 2 cents :-)

Was looking at Panasonic as well since a user has mentioned a below 30K price. Not sure what refrigerant is used by them. Most of the websites don't seem to carry that information.

Not keen on Inverter models. I am OK with the fixed speed ones, will maybe move to them when they have been tested thoroughly in our conditions.

That seems reassuring and thank you for replying.

My sister has three Whirlpool Split A/Cs (two of them are 5 years old) and it is the only brand that seems to work for them. They are wary of LG. Two units stopped functioning (not sure why), they were bought along with Whirlpool machines.

No idea about Samsung.

Even though GW potential of R410a is higher than R22, R410a is better in the sense it does not cause Ozone layer depletion

R32 as well has zero ozone deplition. 1/3rd GWP of R22 And R410a.

My Hitachi Inverter refrigerator has 600a refrigerant. Zero ozone deplition and GWP of only 6. This refrigerant is yet to make it to AC.

By and large refrigerator refrigerants are not preferred in ACs. the only R12 AC I know was the first version of the Voltas Crystal with the B1G compressor.

Great I didn't knew Godrej has a much better green solution.

Greed to save has no end. If there is reasonably priced technology which has less harm to environment then at this stage R32 is the only refrigerant and ACs with it should be on top of the list in preference.

However, the challenge is with the reasonable pricing of such appliances. The Godrej one was 58k I think. That pricing completely negates the advantages on all fronts. I finally picked up a Voltas Inverter for 32.5K all inclusive and that consumes around 970 watts. However at Rs.28k less than the Godrej a back of the envelope calculation told me that I was better off with the Voltas AC irrespective of its close to double the power consumption as against the Godrej AC!

Godrej has priced them insanely. Just like CFL and Led bulbs are priced. As advantage in terms of power savings and saving earth( noble cause) is fully negated by pricing. For example in Bangalore, the usage will be limited to two months @ 6-7 hours per day., it does not make sense to pay double and triple the price for R290 models over R22 models

If we can contribute less heat in those 6-7 hours it's helping slow down/reduce GW.
So high money spent for environment cannot be negated if it is helping in the larger cause which is irreversible.

And why R290? Why not R32 when it's available at a reasonable cost. Even that could help as compared to R22 and R410a.

As technology progresses and mass production happens, R290 would be the choice in future may be if prices are reasonable.

My inverter AC has two "eco" settings reducing the maximum power. I think that some inverter ACs can be set to run at half-power or less. With current consumption of 400-500 watts or less, we will soon be able to run one off the inverter! :uncontrol

Or more seriously, from a small generator or modest solar set up. Inverter ACs lack the surge start-up power drawn on every power up of a conventional system, but I suppose they still draw a lot of current to get started in the first place.

About ISEER , yes that's one contribution to help environment by going for the highest rating. But if that is not affordable, the least and the very basic i.e. refrigerant should be wisely selected. Which again is R32 based on current market scenario and tech advancement.
