Is up to individual. You want a peace of mind, then is better to buy.

Is also depends on brands and past experiences ... good brands like pana (my only experienced) seldom have major issues unless you have 1 lemon unit which is just bad luck. When I bought 7 units of pana ac 10 years ago, only 1 unit gave me problem and the rest are ok till today.

If you are not in hurry to buy one, wait till Dec for year end clearance sale. Otherwise, you can try HLK or Onking.

Yes. I have done it ... 1 5hp now using 1hp

This normally happens when the water outlet is clogged with 'jelly' like dirt and when the filter is dirty.

This is a quick and simple diy, otherwise you need to call the air cond technician.

Remove the casing and use a mini bottle or a colouring brush to clear the outlet mouth area. Then use some hot water to wash it away. Test by pouring 500ml water slowly and it should drain away. Fix back the casing and is done.

In reality, how do you measure ? .....just asking .

Buy a higher hp ac to compensate for the distant.

Double the hp.

If you want to prolong the service interval, you need to add another layer of finer filter. The normal filter are too coarse to trap dust with leads to quick accumulation of dirt in the coil and blower.

The slight downside of additional filter is the drop in air flow and cleaning every 2 to 3 months regularly is advisesble to maintain the air flow.

I bought a meter from a filtration media factory for RM30 and can use for about 8 ac.



I cut to the original filter size and staple it together.

If you are a 'hot' person and always want the feel of cool air, have the ac face towards your bed, otherwise away.

Invertor and non ...
1. Budget
2. If you think invertor save tnb bill, then buy, otherwise non. In theory, invertor is and also depends on user pattern and maintenance.

You place is an odd shape and I doubt placing only 1 ac will cool the room evenly.

With budget of 2k, buy 2 units of 1hp non invertor. If you feel is a hot day, on two ac, otherwise 1.

Place 1 each in the bedroom and study room. You can always interchange usage depending where you spend more time.

Having 2 ac is easier to decide on placement and I am sure you can decide on that.

Have a budget for monthly electricity bill and it saves you the headache of invertor and non.

If that is my property, I will install 2 ac with a budget of 2k.

If you place the ac like the other forumer suggested, you wont feel the cool air at the bed area. That is why I suggest you have the ac face you. On low or medium if you dont want strong wind from the blower.

If you decide on 1 ac, follow the suggestion of the forumer on the placement. You cant have the best of both places having cool air.

When sleeping, why need to cool the work area with 1 ac ?

BTW, I think you need a 2hp ac for the whole open area with1 ac.

AC blow air the same like fan.

If you want strong wind .... set to maximum, otherwise, low or medium.

Buy ac slightly above room size requirements as per recommemded specs .... for human heat, pc heat, change of weather heat during the year, property west facing direction, etc . Specs dont take into account for all those.

Eg .. if you have more people in an enclosed room, human generate heat and it takes longer for a lower hp ac to cool the room and vice versa.

2hp is a suggestion but if you know 1 5hp is sufficient, you know better.

Looking at the layout, I think is better to install 2 ac of 1hp for faster for even cooling of the rooms. Once the cooling effect is achieved, 1 ac can be off to reduce electricity cost.

There is a off timer to set in ac remote. Preset once unless change remote battery.

Having a curtain is a good idea for 1 hp but if is a 2hp, then it will be too cool at night for 1 room even if you set at 25 or 26.

As we discuss further, you can have a clearer picture why I suggest 2 1hp ac.

1 hp ac is selling for average 1k and if you buy 2 is 2k. Installation is a 1 time cost ... average 200 x 2. You have cooling for 2 rooms evenly. Infact using your idea of a curtain, you may not use 2 ac at the same time if you are mostly in either 1 room thus some savings in tnb bill. You on 2 ac only when the need arises.

2 hp ac is selling for average 2 5k. Installation is about 300. The cooling section firstly depends where you place your indoor unit. A ceiling fan will helps in the distribution of cool air.

Go for brand you are currently using and have no major issue, otherwise go for trusted brands like pana or friends suggestion. Trial and error can be annoying esp if it frequently breakdown.

Personally dont like the idea of different brands ac in a house. When the need to troubleshoot, there is always available units for comparison.

Depends whether the technician is able to access it. Normally he will not want to bring down the unit if there is no cleaning required.

Why ceiling and not wall ac ?

I assume then you need to lower you plaster ceiling height to accomodate the ac for its aesthetic overall blending.

Am not using, so can recommend one.
