guys,
will cassette ceiling consume more power?

Please check the spec. Look at the power input and starting amp. The lower it is the better. Cassettes has relatively higher price compared to normal room air cond.

No, but it's more expensive as it has a lower volume.

The design of the cassette is more complicated.

It is better to use wall mount as servicing is more easier.

What do you mean by lower volume?

Added on July 3, 2012, 1:19 pmThe design is indeed more complicated, but it does not run away from fan, coil, filter. Outdoor units are the same. If you are doing a plaster celing, might as well get a ducted unit. Seal it and duct the discahrge can be at the front and at the end of the hall.

any idea how much does Ceiling and ducted unit cost?

Number of units sold in a year.

Installation + unit might be 60 to 70% more than normal room aircond.

design wise no comment but service its just as easy as wall unit, be it normal filter cleaning or chemical wash, as long you got the long ladder


ceiling conceal unit + ducting + liner = 200++% of normal wall unit, and the efficiency of ducted will be lower than wall unit, so the AC nunit must be 1 size up

Service will be messier as you need to access our ceiling.

Lower efficiency of units does not mean that you need to upsize your AC. Low efficiency means you need more input power to generate the same cooling capacity. Hence, if you use ducted units, you electrical bill will be higher. I have not checked this fact, but generally it is like that.

Pay more bill and take longer time and stress the compressor, or pay more, upsize it, get cool air faster… your choice

Initially I thought of installing 1 cassette air con in my living room, but i scrape the idea because the cassette needs 65inches plaster ceiling depth to have it installed. My ceiling would then be even lower

Another thing is because my neighbours house installed cassette aircon, but during installation, the guy damaged the plaster ceiling..he wasnt so skillful. So i realised that in future, just in case it is noisy or whatever or something, I may need to meddle with it and may crack the plaster ceiling a little, so I scrape the idea...also because I was told it will use more electricity since it is a large® unit but then again, I'm not cooling it to be like a storage room..dont know how true anyway

u must be kidding


350mm or 14" ceiling depth is more than enough to install ceiling cassete unit

Agreed.

It is difficult to take down the whole unit for service. Compare the wall mount.

Cassette also easier water leaking. See alot in mall. Dont no why.

And the ugly side is you need a hole beside the unit for easy service. So every cassette unit have a cut away hole on the plaster ceiling.

Why take down the whole unit if its not broken??

Normal filter cleaning just remove the clip n cover, wash the mesh filter, no difference with wall unit.
The cassette type fan blade is easier to clean than the wall type....

If want to do chemical wash, both wall or cassette type also need air con man to take down the indoor unit and pay $$￥ for the service.

Cassette use water pump to discharge the condensation water, if the pump spoil or the pipe clogged, the ac will stop functioning, most case leaking due to poor connection done by ac guy.

As for the access opening, is a must for cassette ac install between slab n ceiling, not that ugly lar…some ppl install wall unit above tv wall panel/ half sunken inside the ceiling/ cabinet lagi ugly lor

For upper floor with roof, no need access opening at every cassette unit, one access to the roof will do

LOL...sorry sorry..not inches..cm....thinking in ft and inches for too long..haha

Anyway i think he may not like such installation, so he tell me such things...i measured the cassette, only 37cm. Still wondering if I should. Is the aircon piping and wiring teh same with any regular 2.5hp?

Do you have any idea roughly how much a 2.5hp cassette type aircond costs?
i'm also considering between the cassette and wall type for the living room.
thanks

Nope. If it is cassette, i dont need to spend, there is an extra unit at my uncle's shop that i can take if i want, so I didnt survey on the pricing. if it is wall mount, i am considering between have 2 units of 1 or 1.5hp because of the layout and the location of the aircon..

still need to think mer, foc wor....2.5hp casstte basic rm3.xk, york rm3.1k if not wrong, i bot 2011 year end
