I was thinking of getting a round metal pipe wide enough to accommodate the idu pipes, cut off the excess length beyond the brick wall, and fill the remaining gap - between the bricks and the metal pipe with concrete.

Isn't the hole position determined by the mounting bracket and marked on the supplied template? The pipes are usually not exposed.

A two-inch plastic pipe is fine. easy to cut to length. It can be cemented into the wall.

After installation, seal the outside end with white cement. That will keep insects/etc out. It is easily broken out if necessary

My ACs do not have open front panel, but the filter wraps around top and front of the cooling coil. All the incoming air has to go through the filters: whatever the design, there will be the same amount of dust and the same amount of cleaning.

Any suggestions?

Thanks

Once such a big opening is done and requires to be filled up and finished, why not go a step further by enlarging the hole upwards or as necessary, so that the refrigerant pipes are fully concealed by IDU. You are going to fill up and seal the opening later anyway.
Placing a 2 inch dia PVC pipe during or prior to installation of piping is a good practice. However, it it is not done and piping installed, you can cut any Polycarbonate Water bottle to the length of the wall thickness and splice it fully. This can now be wrapped around the refrigerant pipe, inserted in the wall. Fill up the internal with loose foam sheet cut pieces stuffed around and between the pipes and finish with White Cement or Plaster of Paris. Leave the smooth finishing part for the professional Painters.

One problem with LG Inverter AC is that the filter is at top of the IDU. This improves the aesthetics, but the location is a dust magnet and clogs up very fast. In Delhi's dusty environment I clean the filter every two/three days.

Thanks everyone! I don't have to mess with a metal pipe. Plastic/ pvc will be convenient. Thanks

I am thinking of buying LG Windows Inverter AC 1.5 ton.

Model LG 1.5 Ton 5 Star Inverter Window AC (Wi-Fi Supported, Copper Condenser, JW-Q18WUZA, White)

Any ideas how it is?Is it good? Feedback on Amazon seems encouraging. Any other Windows Inverter AC recommended?

My current inverter AC has started giving P4 error and technicians don't know what is the issue hence need to buy. Anyone knows what could be the issue.

Thanks for the help.

Price = 32,000 (Plus 5% cashback on my ICICI credit card)
Extended warranty = Re 3,231 (two years, so total warranty = 3 years)
Removal of old AC + Installation = 750
Retailer = Vijay Sales, Dwarka.

I was offered Rs 3,000 for my old 1.5 T window AC, which I refused. Got that one serviced, cleaned, and the gas refilled. It will now do duties in a room that is seldom used.

I am pretty happy with this AC, been using it for more than a year now.

Ohmygod... Mechanics are doing water wash on our hall AC. It is scary wondering where all water will go. Oh well, it is my first time, but I guess it isn't theirs

Three hours later...

It didn't actually go well. Their pressure-wash machine stopped working and they were unable to complete the job. Yes, there was some water spread around.

They are now putting the AC back in functioning order (I hope) and will hopefully return tomorrow* with a working machine.

These things happen. They did their best to fix it.


*Otherwise known as Monday, to fit wife's schedule. I'll complete the story then.

They did, and although they said they had only cleaned one side of the machine, it has made an amazing difference: it is cooling again.

So things can only get better. Hopefully.

Water Wash Finished

The technicians polished off the second half of the job in one third of the time it took the first-visit guys to do their half.

The advised us that every AC should have "chemical cleaning" (I didn't notice any additive, but there could have been one) once a year. They also said that the office bosses never volunteer it, but we should demand it. They said that one other of our machines needs it: should be done next week.

This is how we prepared for the visit. There is a lot of stuff underneath there that needed to be dry!



On the other hand, if your AC is on a bare wall with clear tiles under it, all you'd need is a mop.

The used water that had passed through the machine was totally black. It is now functioning very well again. Except it now has a high-pitch whine: I suspect they might have washed the lubricant out of a bearing. We have to get it fixed: it is not a liveable-with noise!

Also check the Panasonic Inverter AC range; equal features like the LG one. We bought the KU18WKYXF model in March from Reliance Digital and it works like a charm. The major benefit of Panasonic is the weather-resistant silver coated outdoor unit. That was a dealbreaker for me, since my building is closer to the sea in Mumbai.

Spray WD40 if the noise source is hard to reach or use silicon grease if easy to reach. Similar problem happened to my AC as well. The blower motor started making noise after pressure wash. A shot or two of WD40 at the motor spindle fixed the noise for good. You guessed correctly, the pressure wash removed all the lubricating grease and oils.

I have been using the in-situ IDU cleaning with pressure wash for a couple of years. It is a temporary job and the AC required pressure cleaning every 4 months.
I opted for full cleaning this time. They removed the IDU and dismantled the whole unit. Then they used pressure washer on all items except the electronics PCB and the blower motor.
They showed me the muck collected behind the fins - due to the regular in-situ pressure washing. It has clogged the fins so much the CPU of the AC thinks, it is a fault condition and doesn't allow the compressor to reach the full speed.

After the clean up, the AC works like new. In the earlier days, they used chemicals (probably Hydrochloric acid) to clear the accumulated muck. Fortunately the pressure pump has stopped the acid wash.

As a bonus, the power consumption has dropped too - from 8 units a day to 5 units.

I was also thinking, and don't allow them to go pouring coconut oil into the works.

I have silicon grease, ordinary general-purpose grease, and Singer machine oil (and, even, a bottle of engine oil!). I am doubtful about one thing, though. Won't the bearings be sealed bearings?

If you google for that code, it suggests its a inverter compressor drive error or failure. My guess is your compressor is still under warranty. Technicians might be avoiding it knowing its a big job and not something that they can make money on. Push for an investigation and tell them it might be compressor related.
