It the aircon point direct to DB ?

If yes, don't need the switch.

But normally the installation include the switch.

1 Gang 2 Way Flush Switches (RM48) - Both Live and neutral terminate at switch.

As long as it between the spec, not a problem.

Each brand and HP aircon have the compressor pumping alleviation max spec. The spec will tell you how height the outdoor can install compare the indoor.

And the max distance between the 2.

Labor and petrol free meh...

Why people like to buy a aircon without a installer?

Cheaper?

You can tell them what you want and where to place. The extra installation work need extra charge from the std installation.

I go through 2 installation which is not std. Conseal and more than 10ft piping. As I require the outdoor unit to be place ontop the roof water tank area.

No problem for the installer and no complain.

Is it you're not agree with the price ?

Mostly can last nore than 10yrs.

Mind already 9yrs+.

What's wrong with that?

Why related the gas with the aircon lifespan?

Aircon don't require to pump gas in every service or every yrs.

R22 gas will be phase out cause depleted the ozone. Your responsible to takecare the enviroment. It is volunteer you want to do it or not.

Even it replace by R410, it is not totally gone for the R22 gas. It will cost higher since in the market getting less. Till the manufacturing totally no more produce r22 type aircon.

I knew this phase out since 16yrs ago. And my 9yrs+ aircon is using R410.

Never top up or low gas pressure since install time.

If tomorrow they told me no more r410 gas, it doesn't matter to me.

It is not you to care. Your next generation and your kids.

About 40% different from my old bill.

And change from 1hp to 1.5hp.

RM100-RM110

Average 8hr.

Aircond almost 10yrs now.

12mth x 10yrs = 120mth.

Bill save every month RM100x40% = RM40/mth (put it at RM30 or 30%)

120mth x RM30 = RM3600.

Enough for me to

1) buy new panasonic inverter air con now for RM2688
2) Left RM912 for future service.

It is famous in Sarawak.

I thought it is cheaper than Japan brand?

I saw many people using gree brand in Sibu.

That is not 90deg bend. That radius bend cannot conseal into the wall.

BTW, why not cover the pipe? The piping is very ugly friendly to speak.

You're blocking the airflow on top.

Hot air suck from top of the aircon and flow out from the bottom front.

Read the manual how much space ontop require to be clear off.

It is cheaper and economical to run if there is many aircon using. But if using mostly 1-2 aircon or 3, than is is not cheap to run.

Exam your pattern of usage. How many aircon will be use in a night or day.

Multisplit is very famous and normal in sg or some small country. 1-3 aircon per outdoor unit is normal in SG. You might option for this type smaller capacity if pattern of usage is smaller.

I also favor of multisplit instead of whole role of outdoor unit. Which is damn ugly, noisy and messy pipeline.

Just add a mcb point and wiring to the aircon. Std procedure.

Your installer might tap from your room wall socket. If the aircon is 1hp.

But you have to check by yourself are the room wall socket is fully occupy or heavy loaded with electrical appliance.

Why don't hide away the outdoor unit ontop inner side ? The MB1 location. But more inner.

That should make your house front cleaner look. Without that ugly outdoor unit.

The MB2 and living outdoor unit will be noisy next to your room. If the left next wall is the room.

If possible , all outdoor unit fly up to the top. Same place as MB1.

The compressor is a pump. A 3hp probably have a elevation max of 30m. What is the house height till the roof.

The 3hp outdoor unit alone is already noisy. But I guess once you go to sleep, the living room aircon will be off.

BTW, check the 3hp outdoor unit size can fit into that 2nd storey space.
