Something like this... but with the air duct hanging from the ceiling.

looks like a good idea.
it won't be pretty, but i think it will work.

You'll need an exhaust fan at the end of that tube to suck the hot air out ...

For short lengths like a few meters, no need. The fans used in outdoor A/Cs are static pressure optimized with their wide blades and steep pitch angles.

There will be some losses in efficiency for sure, but specific to the guy's issue, the fact that it's going to pull in fresh/cooler air with the ducting installed makes up for the loss and he'll end up with a net-positive efficiency compared to the current setup.

To further reduce this loss, it's also best to keep the ducting as straight as possible.... no sharp turns or hairpins.

I don't use one. I just posted it as a possible solution.

miss X,
your papa is right.
perusing carousell,
just the cost of the ducting, depending on the type, them ductings can be very expensive... thousands if the diameter is big...
it might be cheaper and longer-lasting in the long run, if the unit were relocated, instead of running that ducting...

i am now curious,
how come your papa knew?

UPDATE: Salamat po ulit sa mga input.. Ok na po mga Sir, sa halagang Php 6,500 hindi na namin tinawaran.. Na-relocate na po outdoor unit, nalinis na both indoor and outdoor, nadagdagan ng freon.. Balik lamig na sya [emoji4].
Sabi nung gumawa, baka yung last na naglinis ng aircon namin, binawasan yung freon kasi hindi niya ma-solve yung leak.. Resulta humina ang paglamig.
Umaliwalas pati ang garahe. [emoji41]
