Reliance is famous for its pathetic after sales service and support. Be it Jio or any other Line of Business, Reliance has displayed poor customer service. Reliance is just a Lala's Galla (money box), once money goes into it, you cannot get it back. Forget your ₹900 bucks and just pray that the AC works well. God forbid if you need ResQ's assistance in the future.

We finalized a Panasonic 1.5T 5 star non wifi model by making the payment on 2nd April 2024. I was told the AC will be delivered to home within 2 days and installation will be done 2 days after delivery. During the booking we were informed that there is a separate standard installation charge of Rs. 14xx that needs to paid at the store itself and if we need a stand for ODU, it also needs to be paid during booking itself. Any extra material used during installation will need to be directly paid to the installation guy. Now the wait started for delivery and installation.

As promised, the AC was delivered to home on 4th April by 4PM. I was told to login to the ResQ app to track my delivery and installation. The app promptly updated that the AC is delivered on 4th April 4pm and the service engineer will be assigned within 24hours. Next morning when I checked for the status on the app, it showed me the same status.

I think Mitsubishi Electric has more dealers. Not sure who stocks and sells Heavy. If I am not mistaken, previously, someone - near the PNB - Sector 28 market used to stock.

We have got all in Mitsubishi Electric. Though they have also reduced the size of outdoor units ( smaller now) than in the past, cooling is still better. You will notice a significant cooling difference with a high ambient temperature. Daikin will almost stop working at 46 +

Hi Turbanator,
Will you please share the model number or star rating of your AC?

Also, I wonder how these brands calculate their operating range. Most of them claim cooling in 50+ degrees but struggle when the temperature reaches mid to high 40s.

We have 5 Inverter AC's and they all weather power cut without any problem.

Thank you for your inputs Aroy. You are right, the price most probably had factored in installation cost also for our previous purchase. Do not recall the pricing details but the installation was done by friendly neighborhood electrician/carpenter with whom the dealer had tie-ups. IIRC, Hitachi did not send its own engineers to do installation back then.

Went ahead and purchased the LG 1.5 ton AC TW-Q18WUZA.ASLG from Croma. Croma offered the best price as compared to other LG dealerships that we checked at. Due to heavy rush given the harsh summers, the AC was delivered day after next (something which Croma salesperson informed us about upfront).

Installation engineer is expected to come today / tomorrow. There was a mix-up and our installation request got assigned to an out-station LG dealership so had to get it transferred. They are expected to call me today to fix an appointment.

The salesperson insisted we should get an MCB and not just a regular power plug. He said there have been instances of ACs catching fire due to not using an MCB. Recommended a 32 AMP MCB for LG AC (5000W cooling capacity).

While we will get the MCB fitted for this new AC, for the existing one also, should we get an MCB installed (currently it is connected via a stabilizer to the power socket plug)?

Having experienced a fire in our bathroom due to geyser malfunction (was not used for long time) in the past, am a bit concerned about safety precautions we should take when using such appliances, hence the query.

Anything else which should be kept in mind as part of the installation?

Thanks,
S

In my opinion, the salesperson is fearmongering. Regular 16A power plug and switch is more than sufficient as long as you ensure you have a good quality 3 core cable. Key is to ensure that the wiring inside the plug terminal is proper with no strands cut and full contact of the copper strands with the terminal slots.

Even if you go for MCB, you need a 16Amps MCB not a 32 Amps. 32 Amps will not trip even if there is a fire. 1.5 Ton AC will not consume more than 16 amps of continuous power so there is no reason for a 32 Amps MCB. Even a 16 amps MCB will not trip immediately if the consumption exceeds 16Amps. The time taken to trip depends on the how much more current over the rated is being drawn and for how long.

4 of my LG Inverter split AC's have no MCB on the switch. They are all on the main distribution board.

32A MCB is fine for non inverter AC, but it is an overkill for inverter AC, as the inverter AC has a "slow start", that is it speeds up slowly (DC motor) and takes about a few minutes to ramp up to maximum RPM. I have checked and in our case the 2T Inverter AC starts with 0.9A and slowly ramps up to 9.5A within 3 minutes.

Anyway in case of short the current will be quite high, so an MCB will trip.

I have 2 LG 1.5 Ton 5 Star Dual Inverter Wifi Split Acs. One is a 2021 5-in-1 and other is 2024 6-in-1 model. Due to top floor we need to put our ACs in HC mode for minimum 30 mins before the room temperature reaches 25 degrees. In HC the 1.5 Ton will be working close to 1.75 Tons. My previous connection was Anchor 16A Socket and Plug. Twice it got melted and in 2022 we switched to a 32 amp MCB switch and never faced the issue again. Our 2024 model also got installed with same 32 amp MCB switch.

It's just a matter of peace of mind.

Are these Mitsubishi Electric ACs good for NCR's new highs?

Please suggest a place to buy 2T Mitsubishi split AC in Gurgaon?

Hi everyone, I have following queries regarding the ACs.

1) Between a 3 star and 5 star AC, which would be cost effective in long term in terms of energy bill, maintenance cost?

2) My bedroom size is 13 by 11 feet. Should I buy a 1 ton or 1.5 ton AC? As per , AC buying guidelines, it suggests to go for 1.5 ton. But one of my friend is having 1.0 ton AC for the same size of his bedroom and he mentioned that it is sufficient for him. Please guide.

3) Has anyone used/ is using portable AC? Is it a good option if one doesn't want to buy 2 ACs? How do they differ from split ACs? Are they more noisy?

1. 5 star AC will definitely reduce the electricity bill, especially if you use the
AC for more than 5 hours a day and six months a year.

2. 13x11 room may need 1.5T AC if
. It is on top floor
. Two sides have sunlight falling on them
. If you use the bedroom during daytime also

3. AC works by extracting heat from the room and dissipating it outside. A portable AC cannot throw the heat outside the room, hence will be ineffective. It may at the best act as a cooler throwing cold air on you, but will definitely not cool the room.

Regarding electricity consumption, take the numbers with a pinch of salt, as the electricity consumption depends on the heat load in the room. If the room is on the top floor with two walls facing sun the AC will run longer to cool the room, while a room with a few floors above and no sunlight on the walls will run much lesser to cool the room.

Any way the savings in electricity does not warrant a large difference in purchase price, unless you are in a place like Delhi and run the AC from end March to October

This year's summer has been amongst the hottest, and in BLR we have been using the AC 14-16 hours a day, which is a departure from the norm of max 6-8 hours. Even if these ISEER numbers are under ideal conditions, still it's the only reference. So any ISEER>6/7/8, is preferred and be relevant for next few years.

It's a 2 ton 4 star inverter model but the cost difference between 4 and 3 star model in my case was around 2k rupees, so it was a no-brainer. The installation is scheduled for this Friday so I will post an update later on its performance.

It's been a month since I got the Panasonic 2 ton unit. Here's my experience:

1. Noise levels are acceptable at LO/MED fan speeds. There is another quieter setting below LO at which the blower is barely audible. But it's not usable as the cooling rate drops in some time. I usually keep the fan speed on Auto and it seems to switch between LO and MED speeds from time to time.

2. Cooling levels are average for a room size of 15x20 ft. Room gets no direct light but heat from terrace. Outside temperature peaks at around 44-45 degrees during the day. The outdoor unit distance is within 3 meters. The AC takes around 15-20 minutes to cool the area directly in front and almost 1 hour for the entire room. Having app connectivity helps as I can remotely switch on the AC well before I step in the room. There is a powerful mode for faster cooling but I haven't tried it yet. Good thing is that once the set temperature is reached, the unit works well to maintain it. There are no "too cold" moments, a major issue with our non-inverter units.

3. App connectivity is seamless. All settings can be controlled on the phone, including convertible modes, timer, usage profiles etc. The app shows filter health (no percentage) and energy consumption as well. Since April 30, I have consumed 200 kWh which translates to a daily average of 7 kWh. The usage is around 5-7 hours a day at 26 degrees (mostly) and Auto mode. I believe energy consumption is on the lower side for its tonnage, members can correct me if I'm wrong.



4. It comes with plenty of features. Some gimmicky, some useful. There is a horizontal air direction mode which I found to be very useful. Seven convertible modes can be used to limit the AC's working capacity and save electricity. It's a different thing that cooling starts to suffer at second lowest (55% mode) and is inadequate at lowest (40% mode) setting. Then there is a clean mode to clean the insides of the AC (well that's what I was told ) but I'm yet to try that.

5. Build quality isn't the best. Both the indoor and outdoor units are surprisingly compact and light. While the outdoor unit is alright in terms of quality levels, the indoor unit is quite disappointing. There is a sizeable panel gap at the front just above the air vents. The front cover panel also feels flimsy and low-grade. Quality has definitely taken a dip as compared to our older (and 40% cheaper) Panasonic unit. Remote is of acceptable quality with a white backlit display, no complaints here.

Overall, I would rate it 3.5/5. Cooling and build quality isn't exceptional but the AC scores high on convenience with a good list of usable features and app connectivity. It costed me around 52k after exchanging my old non-working AC. This price includes installation and a swanky V Guard voltage stabilizer, which I think was an unnecessary expense. Hope this information will help others in decision making.

Thanks for reading!

A portable AC does have an exhaust vent which throws the hot air out. So it does help in cooling the room much better than a cooler, however may not be as effective as a split or window AC.



Portable ACs are recommended only if there are absolutely no provisions for fixing a split/window AC - like a hostel room, or houses with very old architecture.

Also, these portable ACs are not exactly cheap. A 1.5T portable AC details at 40k+, which may be in the same territory as a regular AC.

I have a Blue Star 1ton portable AC. Its suitable as a stop gap arrangement. Its not energy efficient. The hot air discharge pipe gets quite hot and if its length is long (AC placed far from window) the cooling loss occurs from it. You have to adequately insulate it to prevent that. Also, the AC is sucking and throwing air from the room to outside, so creating a vacuum inside the room. It creates a negative pressure differential between the inside and outside and of the room which encourages influx of hot air into the room.
I'd say it is comparable to a 0.75 ton AC in the same room.

Hello All

One of our room is 105 sqft of carpet area. We already use Hitachi (17 year now), Hitachi(5 yrs), Panasonic (5 yrs - have spent more than AC cost in repairs). My Inlaws use Carier models and I felt Cartier cools better than above ACs.

I thought of buying 1 tonne Carrier, but family mechanic keeps saying to go for Mitsubishi.

We have floor above us and not direct heat.

Any recommendation for Chennai weather?
