Split Type Aircon: Which is best?

[travajante]

Our house contractor placed embedded AC tubings inside the walls and drain into the regular pvc downpipes. They used cpvc or pex yata which they say is much stronger and minimizes leaks compared to regular pvc pipes. Sorry dont know the exact material they used but usually for high pressure water daw. 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.

Can't remember Doc. It can be avoided since pwede "back to back" installation but I insisted they install the outdoor unit Doon sa Other side Since nakakasira ng aesthetic pag sa harap.

What I remembered is they brought 50 ft tubes and wirings, basta isang Roll and halos ubos yun rolyo

I'd rather look for a nearby service center than SM or any other appliance center, and have them install it.

This is much cheaper and maintenance​ should be fairly easy as you can call them anytime.

The nearest service center around our place is Samsung. I'm a bit worried after reading some problems encountered with this brand. It's only a year old.

Yun din naiisip ko...

Plan is to start talking to Mitsubishi directly for their "multi split type" models... And the possibility to have them install a unit if I decide to buy overseas...

Gusto ko din sana Samsung since meron silang air-free mode and it works well with their robot vacuums...

Pero may 360 mode din naman Mitsubishi

The gel are actially algae. To prevent them from building up, always use the self-cleaning function of your A/C, if available. Either that or leave it in low fan for 30 mins before totally shutting it off.

I can attest that this will prevent algae from blocking the airflow and drain. It also brought down our electrical consumption compared to when the same unit was suffocating in algae gel. During that time, I was having the A/C cleaned every 3-4 months. After religiously using the self-cleaning feature, 5 months out and it's still blowing strong air with barely noticeable reduction in performance.

^+1. The frequency of cleaning will depend on location's pollution. Avoid having units facing roads or the dustiest side & direct sunlight.

In a way we've been lucky. We wanted to hide the tubings, but the installer convinced us not to. With the same reasons you presented here.

Yes....but then there is added cost to do embedment the right way.
When embedded installs on new construction are requested, I would always pre-install the insulated lines in PVC pipes way before the wall plaster is applied. This will prevent unsightly old-new plaster joint cracks. Chipping thru existing painted walls to embed new lines will require masonry & paint work. Both will need lengthy cure time if you want top notch results. To prevent the said old-new plaster cracks that are bound to show months after, I'd clad the entire wall w/ cemboard for permanent seamlessness. All that will be added work & cost for the owner.
With external routing, the addition for the cover is minimal....& when trouble comes, it'll be a big relief for everyone.[emoji4]

Windows, being DIYable, will get you freedom from the AC service people....much like freedom from car dealerships. Washes can be done yourself if you're handy. Some brands like Panasonic & Carrier share the same non-compact unit dimensions. To keep swaps quick, sticking w/ same brands & retaining sizes will save you the time, work, hassle & cost of cavity/blockout adjustment.[emoji4]
