Split Type Aircon: Which is best?

[travajante]

Aircon installer was here this morning for an ocular. He tried to dissuade me from upgrading the drain line from the standard 3/4" to 1" as suggested on this thread. Makapal daw and mahirap ibalot etc etc. He finally relented when I stood firm. The line will extend 22' from the front wall of the garage to the gate.

We may also need to upgrade from a 2.5 to a 3.0 based on the area and usage (living room + kitchen + small bathroom + stairs). We decided on a Panasonic but since we might be getting a bigger unit we will have to check their prices again. They recommend Daikin and Panasonic in terms of reliability. They also carry LG and Hitachi.

If all goes well everything should be up and running by this weekend

Grats, brother John! Daikin if you can. Pana , if you can't.[emoji106]
Good you stood firm on the drain size.[emoji106]

Panasonic installation successful! That 1" drain line is huge!

The whole system spent almost an hour on the vacuum pump. They kept it running while they were wiring and wrapping up the pipes.

I think I overpaid somewhere because they threw in a free breaker even when our box already had a breaker set aside just for the aircon.

They all do that. Grats, brother John!

So many posts on FB with conflicting advices. Some say don't use the aircon or it'll clog with ash or the ash will cause some kind of short circuit. Concepcion Industries says it's perfectly fine to use it.

So, which is correct?

I actually think it's okay to use it dahil air intake comes from indoor air. The outdoor unit blows air outwards naman.

where does the outdoor unit get the air that it blows outward?
from the outdoor air that may be contaminated by taal ash!

i think the answer to the question, is both a yes and a no, depending on conditions, to wit:

if the machine is a gas or diesel engine, the ash, which is actually very very fine crystal material, may be sucked in thru the air intake and not get filtered by the air filter. once it gets into the combustion chamber, it acts as sandpaper material, scouring the cylinder walls and causeing premature engine failure.

if it's our ordinary airconditioning units, the very fine ash will easily get blown thru and emerge past the aircon's heat exchange fins. no damage results.
but if the ash is heavy, it may clog these fins.

if the fine ash settles on our beautiful car's finish, and someone attempts to wipe it off using (any) cloth, that smooth paint job may get scratched beyond belief.

now, if the ash gets inhaled by humans and other animals... see the volcano thread. it's listed there.

my opinion.

#perfectly fine to use it. It will not severely clog up. If it clogs up it will simply stop cooling to protect itself. Overpressure or overheat sensors work. It will not self destruct. I work on chillers

Hmmmm napaisip tuloy ako.. After pala humupa at mawalis ang ash sa kalsada.. Sana pala umulan noh.. Para totally ma wash out sa kalsada yung alikabok.. Sa aircon din ng mga sasakyan uwi nun noh at syempre kapag nadaanan ng kalsada lumilipad mga alikabok..

my fear is,
all that ash will clog the roads' drainage system...
it is probably better to sweep them away and dump them where they will do some good.

samin pwede syang panambak.. yun nga lang sa mga mainroad at sa iba pang kalsada.. tapos paulit ulit nga lilipadin ng sasakyan kapag di mawalisan..

This one did a great job of considerably reducing my electric bill.

Barely a year old, we only turn this off when we leave or when it’s time for me to clean it so most of the time it’s running for 24 hours.

Indoor unit filter should be cleaned anyways.

Outdoor unit needs cleaning, just hose it off.

I dont think any units got short circuited outside the heavily affected areas.

A friend recently opened a shop at a mall and the contractor installed a Samsung 360° cassette type. I noticed that when their shop is full, around 20-22 people, plus lights, it gets kinda warm (though, no complaints naman from customers). Much colder pa sa common area ng mall compared sa loob. Do you think its under powered?

Additionally, the thermostat setting is always at 18deg, the lowest I think. Is it ok to keep it that way? Wala bang masisira prematurely if its always at max temp (lowest)? Also, they notice na sobrang bilis dumumi nung filter, and they said na, everytime gusto linisin ung filter, they need to secure a permit with pay pa ata. So very cumbersome, parang dapat daw nag tap na lang sila ng ac sa mall, rather than putting up their own.

Lastly, should a household ac be treated like an auto ac, wherein you put the full blast blower on first for a couple of mins before and after switching it off?

Appreciate the response/s.

[WallyWest]

AFAIK, inverters are already fully automatic. It goes full blast while the room is still warm and gradually goes on low power (but keeps the compressor running) once the desired temp is reached. That is what makes it so energy efficient. Therefore, there's no need for putting it on fan then switching manually to cooling mode.

If the room gets warm when it's filled with people, then that means the horsepower rating is not enough for the given space. When considering the specs of the AC, it's not just the room size that's considered. Things that produce heat within the room such as appliances, stoves/ovens (if any), and, yes, human bodies should have been factored in.

Anyone here who DIYs their split-type AC cleaning? I just had our AC cleaned ang noticed na pressure washer lang ginagamit for everything.

Kaya kung kaya but not worth the effort. Magbayad ka na lang ng gagawa.

I just cleaned mine yesterday. Two units... LG 2.5HP and a Samsung 1.5HP inverter splits.

Equipment list: Pressure washer, an A/C cleaning cover, a water hose, a bucket and a 3-step A-ladder. I have my kids as helpers.

Saved at least 3k. Wala pang nabasag na clips or bent evaporator fins. Walang malasakit karamihan ng mga commercial cleaners.

Yep sa window type ac ko, 500 lang ang charge per unit, and besides, ang bigat ng unit, i-pull out mo pa, dismantle and assemble. AC tech pa ang naglilinis, sideline nila, nakilala ko sila kasi nung mag reklamo ako sa new ac ko, sila ang pinadalang tech ng Condura.

I also like the fact na power washer lang gamit, no harmful chemicals that eat away at surfaces,

Got inspired and hosed down the outdoor unit of our 9-month-old 2.5hp Panasonic. It was under cover inside the garage so I didn't expect it to be very dirty but no. May bits of Taal pang sumama. The water that drained out was black for a long time. Will just clean the indoor unit's filters for the meantime habang wala pa akong cleaning cover.

Now figuring out kung abot ang hose sa 2nd floor balcony for the 2hp Panasonic's outdoor unit.
