Not all contractors are honest.
You see, you don't setup a website to promote your business, while some need(too free already, not much business sure have time to do so).
Do you have installing air cond's certifications?
Do you simply boast about the type of brackets used? The wire?
But some are boasting about this, so they can charge more, like a M of wire only rm1, they are charging SGD1 for a feet.
Like insulating drain pipe, any problem will only surface out after few years. When problem arise, the owner will look for contractor that did the job. Then the contractor can use all sort of excuse like the owner too long never service the air cond. So the owner stupidly believe this myth and let the contractor redo everything(with pay for sure).
So for the owner to realize this lie after 6 years. By the time the contractor already make enough of money

I until now still can't accept staying in a high class jail and boasting around.
That's why until today I only have money to stay in a 2800sqft corner terrace house

A morning troll on my monthly TNB bill for 1.5HP non inverter(4 hours max, 20 days) and 2HP also non inverter(1-2 hours, 22 days) which all inverter fanboys won't dare to share out on their monthly bills, rather than keep on boasting out how superior their inverter are.
The air cond in your living hall shall be as near to your sofa(or place that you sit most of the time), don't expect to cool the whole hall like your room with just 2-3 hours. It won't able to as the surface area too big.
Also, if you install it on the red box, the cool air won't able to reach your dining hall. So the best place is install on the front wall, then it can blow till dining. Also it can reduce the piping length which will improve the efficiency.
With your usage, just get the non inverter will do, no need to waste money on inverter unless your usage is > 4 hours.

As said, the duration of usage matters. If < 4 hours of usage or the air cond does not cut off(non inverter) or ramp down(inverter), both of them are the same in terms of power consumption.
If you do spend more time on doing research on this, you will know inverter are not that superior, if it does not goes to the ramp down process and short duration usage.

My master bedroom, measurement about 22*12ft, with all the corners, should be about 220sqft.
Living hall about 22*20, effective size is 350-380sqft.
My living hall should be using 2.5HP but the price difference are almost rm600, so I opt for 2HP.
As said, it is near to my seating place, so 2HP are more than enough, I only need a cool sofa area, not the whole hall.

Well, I'm using fan as my main cooling agent, so I never have any problem on getting suffocated.
Still I know most people now prefer to waste thousands just to feel nice. But for me, I just want to see my TNB bill does not goes beyond rm80 and waste money to visit clinics
Like some fanboy keep on boasting how superior his inverter air cond are, but yet don't dare to show the TNB bill to see how superior on power savings are. I have USD100k in my pocket but I don't want to show So what does it means? Nothing.
So are you man enough to show how low your TNB bills are?

Just show your bill lar, don't be a chicken on this

Well, as expected, you don't dare to show. I'm using other appliance also.
Most people that own inverter does not have their bill of < rm80, this is a fact that you trying to deny.
You see hor, by using non inverter and know that it will "consume" more power that cause a person to rely less on air cond to cool the room. When after install an inverter and believing it to be consume less power(which are not actually), they will tend to us longer hours which resulting to same as wasting power. A ceiling fan at highest speed only consume 80W of power while an inverter no matter how it saves also consume > 200W.
So, is who that kakikong, kakisong? Not me basically, but all of you that insulted me but chickened out to show the bill. Remember, is you that step on me first with your lies and I'm using facts to challenge you, but you can't find any fact with numbers to support your lies since the bill will do the talking, not your mouth or keyboard. By just keep on saying "inverter can really safe power" are not enough.

Depending on what temperature you set.
If ambient is 30°C and you want 22°C, it will blow maximum and when reaching 23-24°C only it will start slowing down.
From 30-25°C, it will still blow maximum like non inverter. that's why inverter air cond the back plate will clearly state ***-****W/h compare to non iverter that fixed at ****W/h.
So if that air cond are rated 300-1000W/h, 30-25°C will use 1000W/h and will use 300-500W/h when reached 23-24°C and at 300W when reached 22°C
When it start ramp down matters. If you are using for long hours, still inverter will have help on the savings, if like my usage, it won't have significant savings.
The numbers are assuming working on full load, so in actual it will be lesser.

You need to think on what does his Singlish means
Maintain(English) = maintenance(Singlish)
Good luck on understanding Singlish

Well, as far as possible, don't conceal and can always use a casing to cover the pipes.
Red bricks now quality are very poor as they reduce the curing time significantly.
Is not water vapor being form, are because of cold water causing the pipes to sweat.
If you insist to conceal, then you need to hack bigger hole/drain on the wall, put a 1.5-2" PVC pipe and the drain pipe inside that PVC pipe. With this way, the water will only drop to the PVC pipe. But not that practical since that big PVC pipe you need to have outlet also.
You have to choose, look nice now and headache later or look not that nice but no headache later on.

Nope, since the water dripping from the sweating drain pipe will be collected by the PVC pipe won't be that cold anymore. But I doubt the contractors will do like this, very tedious.

In this world, it won't be pure copper wire in the market, mostly are mixed with other metals.
A 99.9% of "pure copper" can cost rm10 per M.

Yes, you are right. As said numerous time, inverter will do wonders only when it starts to ramp down its output.
Undersize, wall/paint quality all come in to the equation.
Is not like some fanboys just simply says : inverter can really save electricity" type of myths but unable to show actual fact and figures

Looks more like long time never do cleaning on the blower unit?

I know your Singlish are few level higher than English which require people to think few time before able to understand what you are saying.
But can you enlighten me what is fan capacitor?

Is not I simply(is not simple simple as of your Singlish) comment(is not comments as of your Singlish), fan capacitor is used on ceiling fans and not on air cond outdoor unit. For air cond outdoor unit, it is called capacitor or air cond capacitor.
If you don' know the terms, don't simply talk like a pro, this will really mislead people that are new on troubleshooting.
http://www.ufixit.com/news/home-air-conditioner-not-cooling/

Those real hotels(not those buy few shoplot and convert) will be using central type that are much more complicated system. They are using chiller system to provide cool air to each room.
And yes, it will sweat also, especially when it is blocked.

Aiyoh, got slap directly then want to insult me with this
If I were to use my non inverter air cond for 8 hours, sure it will cost me more.
And this I already said many times, using long hours inverter will be better.
The link I provide is the proper way to troubleshoot air cond problems. Not like your way on finding a fan capacitor inside an air cond system

You got mislead by his Singlish liao
The insulator in the market are Insuflex

Copper wire is used for wiring, not for draining. The draining is copper pipe

Maybe translate it to numbers will be better to let everybody understands.
An 1HP inverter are consuming 300-900W/h of power
An 1HP non inverter are consuming 900W/h of power
Room is the same size with same internal setup(bed, cabinet, etc)
temperature set at 25°C, ambient at 30°C(after a hot day)
Both run for same duration of 10 hours, to reach the set temperature, it is 4 hours.
Assuming the room has no leak on windows, door.
Non inverter cut in for 10 minutes once every 30 minutes.
For non-inverter, 4*900 + 1/6*6*6*900 = 9kW/h
For inverter, 4*900+6*300 = 5.4kW/h
Difference, 9-5.4 = 4.6kW/h, if ignoring the first 4 hours, that's 33% of savings.
