I was quoted the following price for a 1  HP installation:
- RM200 for first 10 ft
- RM80 for point
- RM16 per ft

I may need an additional 20ft so it will cost quite a bit in per ft costs

Does this cost sound reasonable? RM 600 + in total

Hi sifu,

Does this York 1.5hp inverter + Rm250 for installation consider ok price?

One shop told me that If York brand are from China and difficult to get spare part?

Why the additional length? Is it because of placement choice or condo restricting compressor placement necessitating long pipe runs? AC should go over the shortest possible route that is above the window so that compressor is placed outside at the AC ledge. Normally around 2.5-3m for landed dwelling.

If your preference is because of deep placement within the room which needs extra length to reach compressor space, account the cost for concealment and painting back the walls or laying exposed trunking.

Finally, note that not all 1HP maximum pipe length (expressed in m or feet one way) are the same. Some could be max 10-15m. Rarely if not very few for 1HP to exceed 15m run length. For such it's more common for 2HP and above which commonly reaches 20-30m max pipe length depending upon model. The only exception where 1HP piping going beyond 15m is when a multi split system where one compressor powers a combination of 2-4 blowers of up to 4HP or more in total.

When we buy aircon, do they include installation ? If yes, can buy now and instal 2 months later ?

Thanks for the advice, cuttlefish and advocacy. I looked at the specs on the Panasonic website and it says 10 g/ m:

Chargeless Pipe Length (m) 7.5
Maximum Pipe Length (m) 10
Maximum Elevation Length (m) 5
Additional Refrigerant Gas* (g/m) :10

Will watch out for this when I engage an installer
By the anyone has an affordable installer to recommend? The quote I got was RM 800 to install. There is additional work needed to hack walls for drain pipe to route to nearest toilet

My aircon contractor just install aircon cooper but I found bathroom pipe are was not insulated.

It will drip due to humid air in the ceiling. Humid area need thicker insulation like 1/2" on top of the pipe diameter. Some do even use 3/4". Some AC supply shops sell insulation by 6' run. Perhaps you might want to find an alternative contractor to rectify that by changing that section to thicker insulation if possible.

Generally speaking, single split and multi split design pressure is based on the refrigerant used.
So for R410a, design pressure is at about 400 psig.
Piping thickness requirement should be the same for single split and its multi split equivalent.

Depending on each model, best efficiency is roughly at about 50% of the rated load.
So user can design around this figure.
But multi split is normally used due to air cond ledge space limitation, aesthetic, etc.
So those will come first before efficiency

It's quite compact. View it from the pictures or the youtube videos.

Hi Sifu,

May i know this sharp Model is good?

http://www.11street.my/productdetail/sharp...d-1-5hp-3161951

The Price is RM1258 and after survey this one the cheaper beside premium model of sharp just missing some feature like self cleaning & Lock on Sensor.

i call aconland shop and they mention the spare part for sharp is hard to find but i prefer other people opinion as shop prefer to sell their product.

Most likely is separate. I just bought a 2.5HP unit and opted self-collection at the warehouse.
A 1hp unit should be able to fit into sedan car as like what Halcyon mentioned.
[attachmentid=9468393]

Already survey for installation, since my house no cooper tube but already got electrical point for ac.

Installation fees go from 300 to 350.

The price is same whether i buy ac with the installer or not.

for multi split system, each indoor unit will have its own pair of piping
so 1 outdoor unit which has 4 indoor units will have 4 pairs of piping connection at the outdoor unit
the other system you mentioned sounds more like VRF - Variable Refrigerant Flow, this has one pair of piping per system, then will just branch to every indoor unit

hopefully consumers will start to appreciate this more
installation cost is still lower here than in Singapore and Thailand

Not all AC installers do that at least not those I use. Doesn't make sense also.

Most of the car now the doors could open almost 90 degree wide. And 1HP compressor is quite small in size.
Nope bro. Hopefully it will be good to me. Lol.. just make sure to remind myself on service accordingly and do the simple easy maintenance to keep it clean on the filters.
