It’s been 3 years and hopefully they never leak.

We're talking long term here, not just a few years, sir. PPR is preferred over ųPVC anytime. Not just material, size matters, too. Drains must be oversized beyond an inch in diameter as they'd be prone to clogging. Water+dirt+dust=jelly sludge.
The options I shared were concocted after seeing fellow designers, friends complaining about the servicing, maintenance of splits years down. Window is a lot simpler.

PPR nga ang pipes ginamit. Thanks for that. Actually it's the contractor who insisted to have it embedded, while I wanted it to be external para madali lang i-repair just like you said. I'm also concerned long term-wise.
As for the AC units, mas madali nga to service window units but the deal-breaker is the noise that window units make. Mas tahimik talaga ang split ACs, inverters or not.
Meron ba window units as quiet as split ones?

Carrier makes 2.0 HP window inverters ...

Proper installation lang sa mga spki type aircon walang shortcut tatagal unit mo na wala problema. I've been using split type aircons more than a decade now and wala problem. Maingay window type acu even yung inverter type and mas tahimik yung split type.

Hehe....there will always be pros & cons. There are less noisy window units, though.
If splits are desired, here are some tips:
-Find the shortest route from room unit to the condensing for max efficiency. The condensing unit must be on a well-ventilated area & accessible to service. Though all-weather, delay rust by sticking on a sheet of extra rain protection, like polycarb or acrylic.
-Insist on larger PPR drains beyond an inch in diameter with the least bends & distance to larger plumbing. P-traps are best installed on joint drains to prevent odor contamination. Common leaks are from clogging. Water & dirt will gel.
-Install room units on perimeter walls to avoid routing lines thru ceiling. If ceiling routing is unavoidable, lay the properly insulated tubes & pipes on a sloped gutter tray all the way to the exterior outlet. This will handle condensation drips. Leaks & electricals can be a nightmare to sort.
-Avoid cassettes when you can. Drain is by pump, not gravity. And, ceilings will tend to have blow marks & finger prints from service.
-For easiest trouble shoots & swaps, opt for exposed lines over embedment. Just cover the unsightly w/ removable plastic or aluminum C-sections.
True, proper installs, attention to detail, following standards & using reliable brands can give trouble-free split enjoyment for a long time. Taking measures to address known contraindications are just ounces of prevention that will outweigh the pounds of cure.

Just sharing, sir. Thanks.
Note that free-install offers are contracted out. Discuss & insist with AC vendors & their contactors the detailed install specs & procedure. Chances are they'll request a lil add-on. Negotiate the cost, never compromise the specs. Some will contradict, sweet talk, convince & guarantee you with their 'experience' & 'standard' practice....the GOOD ones will agree with the sound request of proper install & materials.

as trav says,
wag maniwala na weather-proof sila.
install a protective roof.

and make sure just how much all those tubings will cost you. sukatin nang ma-igue at linawin ang condicciones ng pag-gawa.

I have one split type A/C with approximately 40+ feet copper tubings installed from one part of the house to the other side.

well, if it can not be avoided...
errr...magkano po siningil ng nag-kabit, por metro?

my colleague chose beauty. the tubings were buried in the wall.
hayun, when it started leaking, the repair bill was also a beauty.
hindi na niya pina-tago sa loob. pinalabas na lang niya.
