My 5 year old Daikin split AC's PCB died a few days back during a voltage fluctuation despite having a stabilizer.
The service guy quoted a bill of 5600 INR for PCB replacement.

I've still not gone for the renewal though.
I have asked a local electrician to try and repair the PCB, let's see how it goes.

Will need to get a good stabilizer and spike protector also.

Could be a lot worse!

But could be a lot better if you can get a guy with a soldering iron to fix it. Good luck!

I have purchased a 1 Tonne Carrier Octra 3 Star Cyclojet A/C for my study room of size 120 Square feet. Price was Rs. 31,000 after discounts. The installation was done by Carrier Service personnel for free.

The technical specification and other features of the A/C can be found here

The outdoor unit of the A/C is cylindrical in shape, unlike conventional boxy ones, with the fan at the top. Carrier calls it Cyclojet and was introduced quite recently. This was the main reason for me to buy a carrier A/C as I wanted to check it out. There are mixed reviews about cyclojet though. Long term reliability and performance remains to be seen.



Looks: 8/10 Looks good, not great. The indoor unit is small being a 1 tonner. It has a bright white LED display for temperature. Outdoor unit looks fancy though

Price: 9/10 I believe I have got the A/C for a good deal.

Noise level: 9/10. Super low noise levels.

Cooling: 8/10 Although it will not instantly chill the room, say like a 1.5 tonne fitted to the same room size, it cools the room in about 10-15 minutes.There is a Super Turbo mode for quick cooling.

Power Consumption: Although too early to comment on it. I expect it to consume anywhere between 6-8 units per day for eight hour operation.

Installation: 8/10. The service personnel were professional in their approach and did the installation in clean manner.

Service: Although too early to comment on it,friends vouch that Carrier has got a pretty good service network and they do respond promptly.

@BLACKBLADE; Carrier lost a lot of their Mojo in the past few years. It is always good to see them coming back. Let us hope. Incidentally the original Voltas was Carrier.

Guys, how important is a voltage stabilizer for an AC? I run all my appliances - refrigerator, TV, AV receiver - without stabilizers, and has held up well.

I have shelved my plans to run the AC on UPS until the day I have enough money to buy a solar setup and a large UPS, so the plan for 1.5T Daikin stays. I am waiting for payday to come to make the purchase.

As per my recent experience a good spike protector plus a good stabilizer is a must for costly equipment.

The day when I got that voltage fluctuation, my home theater setup was powered through a Belkin spike protector and a V-Guard stabilizer and the protector cut off the line during this fluctuation.

However, my AC was through a generic stabilizer only and the PCB went kaput.
Belkin saved my amplifier, PS4, etc.

Was it the stabilizer or the spike that cut off the line? My LG tv is going through a Belkin Spike that is connected to an APC Stabilizer which is receiving power from the mains, which is also protected by a full house UPS. Inspite of this the TV board had conked out and needed replacement a year back.

It was the spike since I could see the power safety cutout light.

Do you mind sharing the link or an image of this spike. I only have these kind at home - about 8 of these -

This is the one that I'm talking about.

Hmmm... Mitsubishi or Daikin... Daikin or Mitsubishi....

Decisions, decisions. I fancy Daikin (but for no good reason other than brand bias towards seeing Daikin/General as the luxury brands) but I am not going to get specially corrosion resistant.

The Mitsubishi has, it seems, special coating on indoor-unit components, even reducing dust build up, and blue-fin protection on the outside coil. Both have copper components, so no aluminium-repair problems in the future.

i have two sharp 1 ton inverters and so far they are running good and its almost three years. would like to know if we can do the maintenance as DIY as the so called technicians just pour water and say they are done. Outdoor unit service seems fairly easy but i am skeptical about touching the indoor unit and you-tube is a bit confusing.

Yes, you can do the regular maintenance yourself.
Need to clean the air filters and the outdoor unit.

Almost all indoor units have a pop up cover which can be opened and filters can be taken out for cleaning.

Thanks Buddy. I am already doing that. But i wanted to go the next step. Means completely cleaning the indoor unit either with a coil cleaner or some other method as lot of accumulated dust in the internal fan and coil.

That also can be done fairly easily.
Only need to make provision for draining the water, etc.
Spray the cleaner, wait for some time, spray water.
