The real good efficient is the old daddy gas. R11, and R12

Already buy, don't ask how much lah. Later you find out is cheaper your heart ache.

My 2 cents.
Why not put 2hp + 1hp. At least you can focus the cooling point where you need. If only one, your cooling to dining area will be longer time. By than, you already finish your lunch / dinner.

Cold are move downward, but of course for long running hours is better to cover the stair area.

Mine is 2hp + 1hp, with 2hp, my living area is just enough cooling, but not to the extend of real cool. My dining area take longer time to cool down if only switch on the 2hp @ living area, when i have large group of people dining or "open table" during CNY, i switch on the dining area a/c together with my living room.

Midea oem to many company including some you listed above. Panasonic have better remote, and silent. Sharp I would say ok lah.

I am using 4 sharp, 1 panasonic, 1 york.

Sometime is also depend on luck.

Last time i know Acson oem from York, so quality should be in par with York. My mom house have york and acson, both controller can swap and use.

Noisy to someone maybe ok for others. Ok for someone maybe silent to others.

is better know the technical spec like db so you can roughly know the technical noise level.

Like someone mention panasonic not very quiet, but acceptable to me. York is noisy, but putting on living room is ok.

Forget to add, db level you need to ask at what fan speed level.

Agree, all product will deteriorate over time, even when service it still get louder over time. My installer do told me before.

The most silent is centralized ceiling type. My 2cents.

Dry mode is mainly use in 4 season country. At certain point of time air is very humid you need to use dry mode. Especially when the area have lots of electrical / electronic items.

Not good for room, it will make the room very dry. Skin will dry, mouth will dry.

Personal preference. To me 27 really not nice especially if area is all closed. For close area still prefer 23 our lower.

Reliable, York lo

Don't only see 1hp, 1.5hp.... Check the btu when you want to buy.

Also some AC have the powerful function. Like my Panasonic inverter, the powerful function is run at full load.

Cal you won't get good price

May not be sewerage pipe, can be rain water pipe, but doing that way is wrong, your building management find out you have problem. If is rain pipe, heavy rain you risk water flowing out.

See if it connect to any of your toilet our above toilet.

I think the non inverter got two version one with ion another without ion. Get the ion, according to the saddles person is more reliable than the non ion, cause is newer design.

When I choosing York time (last year), legend explain and show me the ion and non ion version. The two physical outlook is difference. I told himYork make lots of noise in my room. He agreed and point out the ion version is quieter, cheaper than most model and for living room is not to bad. That is the reason I have York in my living room now.

My noise level is the blower section, and what I mean on the physical blower unit is difference. The non ion i saw is same version design as my old room York.

Also I did not mention model as I don't know the model. The non ion model now could have change.

Lay time i user vacuum cleaner to suck the jelly out but you need to make sure the vacuum can suck water.

If A/C generate high BTU take up higher wattage is normal, but if higher btu can be generate using same or lower wattage (comparing another model) mean is very efficient.

Just like car, if 1.5L engine can generate 200nm torque, vs 1.8 generate 230nm torque, you don't know which engine more efficient. Actually 1.5L more efficient. <not actually the correct way of comparing>

But If i say this engine use 2Liter petrol to generate 200nm torque for 10 mins, vs another engine using 1.8Liter petrol to generate 200nm torque for 10 mins. You know which one more more efficient.
