  • Na check ko ung fan.. napakadumi na pala


    Linis lang ba to mga sir?



    Nasagot mo na pala tanong mo o :) . Barado na yan kaya hindi makadaloy sa drain pipe yung water discharge. Ayan naghanap't nakatagpo ng ibang butas na dadaluyan sa indoor unit mo.
  • @mikoy

    kitang-kita kung gaano kakapal ang dumi ng fan mo. siguradong mas terible ang dumi nyan sa evaporator/cooling coils, may hangin pa ba lumalabas dyan? ipalinis mo na.
  • @musicgeek

    Ty sir. Ung algae po sa outer unit normal lang ba un?


  • ^Yes. Since water + all sorts of dirt = algae (lumot) . Palinis mo na yan AC mo. The cleaner will flush out the dirt from your unit and inner part of those tubes using their pressurized washer. So condensate can flow out normally from your aircon. Ask the cleaner if they can clean the outer part of the tubes. Abutan mo na lang cguro. Or you can wash those using water hose. Then clean your surroundings too and avoid standstill water (mixed with soil) buildup from infiltrating your drainpipes. Iwas sakit na din lalo may pandemic tayo.
  • algae po sa outer unit normal lang ba un


    In copper lines/refrigerant tubes? Not actually. That means the pipes are meeting the atmosphere—meaning it is pooooorly insulated. Condensate should never form on those areas, you need to have that reworked. I'm prolly guessing based on the diameter of those lines, they didn't even bother putting EVA foam tubes.

    Maraming salamat mga sir.

    Meron na ako for schedule mamayang umaga at kausapin ko sila about copper lines/refrigerant tubes.

    Nagduda ako dun sa last cleaning na free. More than 30 mins lang ata ung nangyari. Napansin ko na di nila tinanggal ung fan compared sa mga napanood ko sa yt.

  • Goodmorning :) need your insights mga sir

    4 years old LG 2.0 HP inverter split AC. This problem started bago ako magpalinis ng AC months ago.

    Nag a ice po ang indoor unit if 24 degrees na ang room temperature (i read my room temperature using a xiaomi air purifier and wall thermometer). I also use a wattmeter. If kaka on lang ac and talagang mainit it runs at its full 2000 watts para mapalamig ang room, during this period walang ice nafoform, as in parang normal lang. Pero after an hour and a half and papalapit na sa 24 degrees ang room temp, start na mag throttle down ang compressor. This is where the problem starts. When wattmeter reads 1000-1200 watts and 25 degrees na room temp ice begins to form sa condenser unit. May slight fix ako dito. I use the "WATT OPTION" button sa remote to dictate the compressor na ang maximum power lang na pwede sya magfunction is 60% capacity, wattage reading sa watt meter drops to 600 to 800 watts, then the icing on the indoor unit slowly stops. A quick fix tho not ideal dahil hilaw na lamig nya and matagal maabot 24c. Kinda hassle kasi need pa manually iset na gano everytime i use it.

    Bagong linis narin po pala ang AC, replaced na ni tech ang R410a (refrigerant was weighed) and navacuum pump narin. To sum it up, bakit sya nag a ice when the room temp is almost 24 degrees c na? Salamat po.

  • Tanong sa mga experts sa aircon. Safe ba gamitin ito sa inverter aircon para panglinis at pangtanggal ng dumi?

  • @lynkchiz. Ano room.size mo. Baket 1.5hrs bago mapalamig ang room?

    Malamang may leak yan ng refrigerant o hindi pure refrigerant (fake) ang ginamit

  • @phobia
    kemrad coil cleaner gamit ko, ok naman
  • Gusto ko sana malaman kung safe yun gamitin or pwedeng ma damage yung coils sa long term. naitanong ko sa nagrerepaire ng aircon noon at sinabi nya na nakakasira daw ng coils yung mga product na nagfofoam. dishwashing soap daw pwede na. totoo kaya yun? ang kaso lang napansin ko, hindi natatanggal yung mga dumi na sobrang dumikit na sa coils pag dishwashing lang ang gamit.

    oversize ang 2hp para sa room ko sir. tancha ko lang 1 to 1.5 hours bago mag settle sa 24 degrees sana. sir na leaktest narin dahil vinacuum nila and sinabi wala naman daw leak. bago pinalitan ayun nga nag a ice na sir bago mag 24 degrees c ang room, after mapalitan refrigerant ganun parin sir. pull down na next option. ano kaya nagco cause nito na pag nearing 24 degrees na room temp mag a ice na. pero pag kakaon palang naman di nag a ice.
  • Usual cause is kulang sa refrigerant, pero since nabanggit mo naman na properly weighed yung refrigerant charge, next possible cause would be the expansion valve, pero hindi basta-basta nasisira yun eh. Na-compute kaya ni technician ang proper amount of charge vs haba ng lines mo?

    yes sir sinukat niya ulit mano mano and pasok sa stock na timbang ng refrigerant base sa haba ng linya, dinouble check pa namin sa google and tama yung weight corresponding sa haba ng lines.

    Pati yung technician ko sir baffled and first encounter niya na ganitong case. Even called up his superior, walang maisagot unless i pull down na nga, Na bakit pag 24 degrees na room mag a ice na indoor, ni hindi maka tungtong sa 23 degrees c ang room temp, temporary solution ko then is set lang sa 25 degrees in which minsan e hindi enough para maging comfortable ang room.

    Ang mga split type inverter (LG) po ba may expansion valve din or electronic expansion valve na dahil inverter? thanks po, really frustrating na itong problema na ito, ayaw ko pa naman sana gumastos para sa new AC :(
  • Yeah, baffling nga. Saan naka-install ang indoor unit? Malapit ba sa bintana? How bout keeping the fan speed at max if may ice formation pa din?
  • @lynkchiz,

    Baka barado yang unit mo. You may want to check if any of our similar experiences / solutions help:

    1. Detailed & meticuluous cleaning of @statix and my unit wherein they take apart the indoor & outdoor unit for thorough cleaning. It's illustrated in the new DC inverter thread. Sa post ni @statix naka detalye how the cleaners remove even the drain pan to make sure there ain't any dirt that's stuck up in the unit. This is more of proactive maintenance but perhaps this can solve minor clogging.

    2. One moderator posted (in the 400+ pages old DC inverter topic) that his kolin AC na mahina buga ng hangin. It might be different manifestations sa kanya, BUT baka same solution to your situation.

    NormanABates wrote:

    napa ayos ko na ang Kolin ko. i have to join this FB group para madami choices: Inverter Aircon Technician

    This is what the technician did:

    Technician 1: Nilinis nya aircon. usual na linis using pressurized washer. mga 45mins to 1hr siguro. when we put the unit back, sabi ko same paren, walang effect. He then called a backup and told me to wait for his companion(the main technician).

    after around 30mins, dumating na galing din sa service.

    Technician 2: Sir, ano pinalitan dito dati?
    Me: Fan Capacitor.
    Tech2: Tested it. 4.5v is reading 2.9 only. Sir, mahina na, palitan na natin.
    Me: ok,
    Tech1 and Tech2 went out to look for a 4.5v capacitor. after around 30mins, they came back with a new capacitor, smaller but same capacity na 4.5v

    they put the capacitor and tested it. still the same! sobra hina ng buga. He then removed the top cover, lumakas yung buga! Then put it back, hina nanaman. Thats when he told me, madami na stucked na alikabok sa front radiator.

    Tech2: Sir, linisin ulet namin. Bili ka Liquid Sosa.

    Tech1 and Tech2 cleaned it again using liquid sosa mixed with joy dishwashing liquid. Maayos at halatang di nagmamadali si Tech2. Lahat ng fins, dinadaanan nya mabuti. After around 1 & 1/2 hour, done na sila. I remember yung radiator din pala pinalitan 'daw' nung sinabi kong 2nd na gumawa ng aircon, now i know liquid sosa lang ang katapat.

    Yung hangin nya, abot na sa dulo ng kwarto, noong di pa nalilinis, kahit 1 feet ka lang sa tapat nya, di mo masyado ramdam yung hangin.

    Bale eto ang ginawa: Deep cleaning using Liquid Sosa to remove stucked dirt sa radiator and changed the Fan Capacitor.

    Name ng aircon Technician: Kuya A/C - Aircon Services.

    Fee: 700 cleaning + 1.8k capacitor(3mos warranty) = 2.5k

    pull down na next option.


    That solved my sisters panasonic st inverter na nagyeyelo din coz of stucked up dirt. May kamahalan yan, costs nito is P3,000 sa kakilala lang nila technician. I was quoted P8,000 by authorized Daikin service dealer for that.

    In any case, suggest you get 2nd opinion from other techs.

    hi sir yes triny na naka max fan speed. same parin nag a ice pero kaya nga sa post ni statix medyo mahina na buga compared sa nung brand new siya. kaya need na siguro ipull down para ma general cleaning.

    hi sir musicgeek di ko na kinopy paste buo pinost mo at baka mapuno po thread hehe, anyway sir salamat sa very informative na post, very important information na baka nga need na ng thorough cleaning, humina na nga buga niya compared nung sa brand new pa siya 4 years ago. siguro mga 1/3 ang nabawas sa lakas ng hangin ng buga niya sa MAX speed compared nung brand new siya (bago narin pala indoor fan motor nito, tinatry ko lang irule out noon kaya napabili ako),..

    Hmm ano pa kaya ang puwedeng rason? how much is too much na refrigerant? kasi if 120psi ang refrigerant niya ngayon baka puwedeng sobrahan ng kaunti like 130psi? para sure lang na tumaas ang saturation point niya which is above 0 Degrees C ( zero degrees celscius). any opinions mga sir?
  • ^If I were you, first order should be to search for an expert technician. One thing I've learned in this forum's not to confine ourselves with traditional techs as they offer limited solutions. It's best to find repairsmen who can think out of the box like moderator NormanABates case. Try mo JDL Electronics. They have a Youtube channel and looks to be they're very knowledgeable in AC servicing. Search mo na lang sa FB yung contact number nila.
  • @lynkchiz
    nung nagyelo yung split type ac namin, because of two reasons lang, kulang refrigerant and madumi yung ac. since verified na hindi kulang yung refrigerant then tingin ko marumi yung indoor unit niyan.

    our ac is used 24/7 and we have pull down cleaning at least 2x a year. hindi na kami nagpapalinis ng hindi pull down since hindi malinis ng maayos.
  • sir frequenzy,
    thanks for sharing. dahil nga ngayong pandemic 24/7 narin sir si AC. baka nga hindi na malinis ng husto ang indoor unit kaya ganito nag yeyelo na. confirmed narin na walang leaks and properly weighed ang refrigerant yet the problem persists. sa 4 years na buhay nito never pa na pull down. mukhang ito na nga ang solution. wish me luck! ipapapull down ko na ito sa weekend. thanks all sa insights niyo :) mabuhay po tayong lahat
  • @lynkchiz
    wow 4yrs, cgurado nakadikit na sa fins yung dumi niyan. yung sa amin kasi after 6months nararamdaman mo na yung difference kapag bagong linis.
