They run concurrently, ie, 3 years for indoor unit from date of purchase and 10years for compressor for outdoor unit from date of purchase.Look at the energy efficiency as well when deciding.

QUOTE(epie @ Jun 7 2020, 12:29 PM) [attachmentid=10510220] I have been using Sharp Inverter air cond since 2015 with no issues. After factoring in cost savings, ended up with Sharp instead of paying more for other brands. guys, based on this energy consumption tested by suruhanjaya tenaga...this is the lowest consumption i can find for 1hp aircon any review on this? Purchased this same model you listed recently for my dad's room to replace a 15 year old Mitsubishi aircond which was falling apart. Just installed two weeks back, fast rapid cooling and compressor is quiet (barely audible) compared to my neigbours Panasonic Inverter which has a quite loud buzzing sound and based on experience, Panasonic air cond tend to become noisier as they age. My older Sharp inverter is equally quiet even after 5 years of daily use. One of it runs 24/7. Only downside will be spares availability if it breaks down (mine didn't), but I don't expect modern aircond to last more than 6 years; as long as I can recover the cost from energy savings within that period;I'm happy. |

QUOTE(xphr3ak @ Jun 8 2020, 07:51 AM) If i am not mistaken the highest EER is Sharp AHXP10VXD(17.71). Yeah but for the price, recovery will take a long time. EER around 13 and price range around 1.2 to 1.3k can recover cost from energy savings quickly; especially if you use the aircond extensively.QUESTION: Is Panasonic CS-U18VKH(2hp) has strong and long airflow? Thanks. Our monthly usage soared to 1500 kwh; as one of the non inverter aircond was faulty and drawing high amount of current. Replaced both with Sharp Inverter. So far based on daily average reading, usage dropped from 50kwh/day to around 30 to 40kwh/day |

QUOTE(thor74 @ Jun 8 2020, 11:54 PM) The energy saving rating comes from Sirim so they are consistent with other brands. Sharp aircond is made in Thailand for our region, Midea doesn't have an Aircond factory at Thailand as of yet; don't think Midea is manufactured in the same factory as the compressor and indoor unit design are completely different. Usually if they come from the same factory; certain parts will be similar.Nowadays Sharp aircond is ODM (design and made) by Chinese manufacturer most likely Midea after Sharp is sold to Hai Hon (Fox). However, the newer sharp aircond feels more cheaper built compared to my older inverter unit. Anyways, hoping for trouble free period for 6 years. By then I have fully recovered the purchase & installation cost. This post has been edited by dayalan86: Jun 11 2020, 01:07 PM |

QUOTE(Momo33 @ Jun 27 2020, 01:43 PM) so for Aircond ...most of the electronic components can last around 10 years if put on NORMAL use. Yup fully agreed; that's why when installers tell me about expensive spares for brands other than Daikin or Pana for homes; and I counter them back as to how often do home owners repair air cond which have damaged PCB board or other components which can roughly translate to almost 40% of a new air cond cost and they do agree with me. For home owners, repair cost is moot but warranty service call is the determining factor. In this case Midea and Sharp; are equally good as the other two major brands (from experience)components degrade over time . Airconds Performance usually degrade over time . with loss of cooling and higher power consumption . like 5 to 10% so I feel after 7 years regular use , time to start looking for a NEW one .. wait for better offers during Sales. . so why use a 10 years aircond when you pay more for power and less cooling. do a ROI will help . I calculate the ROI for my electrical equipment up to 5 years of age except for fridge; which I expect to last about 10 years or so before being need to be replaced. Momo33 liked this post

QUOTE(shinchan99 @ Jun 6 2021, 06:55 PM) Yeah we are using two units. 1.0 HP and 2.0HP J-Tech Inverter for more than a year now.I am also using the older 1.5HP and 2.0HP Eco Inverter Series from Sharp which has a better build quality compared to the J-Tech Inverter units. The new 2.0HP J Tech Inverter has follow me function (the louvres is motorised) to direct air your way. Initially got Sharp Eco Inverter series because of the coanda airflow feature but now other brands have it too; however, the newer J-Tech Inverter energy efficiency is higher at low price point. Thus, went for Sharp again. Our Eco-Inverter series is 6 years old now; compressor is slightly noisier (buzzing sound when it hits some mid frequency) and then it goes away on the 2.0HP but still very much quieter compared to our neighbours Panasonic Inverter Air cond which are newer than ours. Our 1.5HP unit is run nearly 24/7; also no issues with it but we service every 6months to 9 months once. Sharp indoor unit fan noise can be loud (can hear wind blowing sound) if on high speed probably due to the long air throw feature, to me it was comparable to Mitsubishi Electric AC sound and quieter than York (now Daikin).

QUOTE(SheepGeeks @ Aug 4 2021, 12:59 PM) Inverter air con will only save your bucks when the space is totally enclosed (no leakage) and the capacity of air con is sized accordingly based on the space. Depends on set temperature as well, if always set AC below 24 DegC, then best to get Non-Inverter as the AC will keep running at high power and unable to achieve the set temperature within 3-4hours, if set below 24 DegC.It tend to tweak the compressor speed upon the temperature is achieve, hence, reducing power. If the space is frequently leaking out cold air or the air con is undersized, the compressor will run full speed all the way, hence, equivalent to non inverter unit. So far all my bedroom inverters are set at 24 - 25 degC and we use it conjunction with ceiling fan to spread the cold air around dickybird liked this post

QUOTE(shinchan99 @ Jun 6 2021, 10:22 PM) price point is cheaper.. you have any feedback or experience using this brand? Never tried this brand air con before, and realize many air con shop don't carry them as well.. I am using Sharp Eco-Inverter (The earlier model since 2015) and working fine with no issues at all.J-Tech Inverter Build quality is cheaper compared to the older Eco-Inverter type and particularly our 2HP unit has been having random power issues after power failure. I have another 1HP J-Tech Inverter which has no issues at all (1 year+) The 2HP J-Tech inverter will refuse to switch on (totally Dead) until few hours later after a power failure. Haven't been able to diagnose the cause; as it is out of warranty now (1 year +) and by the time we want to get the repair guy in, it starts working fine and dandy again. All our Sharp AC run more than 12hours a day during this pandemic. |

QUOTE(Snoy @ Aug 5 2021, 10:40 AM) Please be aware that the mainstream inverter aircons are normally categorised as higher end model than the standard non-inverter variant. If you want to set the AC at 16degC better get non inverter, the AC will never be able to achieve this set temperature in a normal sized bedroom.The cooling capacity is also higher even the compressor is running full speed. This means even the inverter dynamic speed feature has not kicked in yet, it already consumes less power than the non-inverter lower end model. The inverter tech is already in the market for many years and this is NOT the only tech for saving electricity in aircon. If your aim is to save electricity, an inverter aircon is the one to go regardless of any environmental factors if we are comparing the same HP units. Of course, the next steps are to consider the correct size unit, house sealing and etc. This post has been edited by dayalan86: Aug 7 2021, 12:27 PM |

QUOTE(Snoy @ Aug 7 2021, 08:36 PM) These are not good benchmark examples. Yup correct but you will not be able to fully enjoy the energy savings of a Inverter Aircond as it tries to cool down the room to the set temperature but you are right that from the get-go; higher end models tend to provide the energy savings but if you do a btu / watt / RM ratio comparison; you will see that the capital expenditure on this models tend to be much higher (unless price has significantly dropped & technology has improved a lot from the comparison I have done during 1st quarter of 2020)Although we are setting at 16C for both units but the cooling capacity is different. The key is the btu per watt. Higher end model (even inverter feature has not kicked in) has better efficiency. In layman term, when we set to 16C, inverter Aircon may cool down the room to 20C but non-inverter can only cool down to 22C with the same power consumption. |

QUOTE(Snoy @ Aug 9 2021, 10:13 AM) Please try to compare again now. Yeah will do if I am shopping for a new unit Basically, non-inverter model has higher (50-130W) peak power consumption than other models. That means even we run both in peak mode, users can enjoy better cooling experience and lower electricity bill. The initial discussion was about saving electricity bill cost. The purchasing cost was not considered. If this has to be considered, please also factor in the gained features (fast cooling, ionizer, connectivity, etc) and experience (cooling effect). Your formula can become (btu/watt + features + experience)/RM ratio. The only cost concern is the part replacement for inverter models is significantly higher. More features also mean more things can fail. But this reliability can be subjected to brand, maintenance, installation, usage and etc. |

QUOTE(Freya.ch @ Oct 29 2021, 11:30 AM) One of my air cond (Panasonic) the red light also keep blinking and will automatically stop after a while (maybe 30min or so) . Last the aircond service personnel told me because of the gas leakage. That day they test it, the aircond did not off itself after some time and I don't see any blinking (so far). The room is a room that I hardly use nowadays, so I dare not say is completely solve , but at least on that day itself, is working fine. The personnel told me that air-conditioning blinking can be caused by different issue, better check first Lot of issues can cause it, we had one York (Old Type) with similar issue, one guy told us PCB board, but after replace PCB board same issue.And the issue doesn't pop up when the service guy is around, eventually asked the guy to remove and take the AC back with him; will probably replace it with a Midea or something cheap, as we use this air-cond rarely for our living hall. |

QUOTE(pigduck @ Apr 21 2022, 05:45 PM) Someone corrected my post above, newer inverters achieve efficiency by running at max power to cool down the room and then drop the speed to maintain temperature. This achieves quick cooling + savings, if the unit has high efficiency. Older inverters, work by trying to run at lower speed first and gradually going up to max speed before reducing the compressor speed once cooling is achieved, this causes delay in cooling and subsequently not much savings during initial start up period of the AC. Again, how much capital outlay vs savings you are looking at needs to be calculated and I have not done this, But will find the cheapest 5 star rated air cond (if I am shopping for a new AC) and discard it once it breaks down, probably will go for Midea or so next. |

QUOTE(pigduck @ Apr 22 2022, 11:23 AM) Right. Do you think this then causes the wet effect on the air conditioner thus creating the white jelly (mold)? I feel like my Panasonic Econavi is way too wet. I had another room that now uses a Daikin and in the past MAY have been a Panasonic used to have white jelly or ice but not anymore. Air cond's have a rated capacity to cool a certain size room, sizing of the AC must take into consideration the dimension of the room and heat load (sun ray facing etc); Otherwise it won't be powerful enough to cool down the room to desired temperature.Maybe we set the temperature too low thereby creating ice / condensation on floors and the air cond was too wet and couldn't dry in time thereby creating white jelly (mold). Panasonic is really lousy now that I'm thinking of it. The Daikin also suffered from white jelly until I'm not sure what I miraculously did to stop it. I think I set the temperature higher. So roughly, 1. use a 1 HP non-inverter at 22 degrees for a big-ish room so the compressor is constantly running and not shutting off and on 2. could use a 1.5 HP non-inverter 22 degrees for big-ish room but it might reach 22 degrees faster and the compressor cycle on and off through the night thereby wasting electricity or it runs at 1.5HP all the time vs the 1HP thereby eating more electricity anyway 3. use a 1.5HP inverter set at 24 degrees for a big-ish room so the compressor runs at a lower speed but doesn't shut off and turn on thereby saving electricity Some times the end goals of ppl are different - some want a cool room, some want to save electricity The claim with the 1HP is that it takes longer for the room to cool down but we want it to be a constant cooling. Different goals again. Maybe I should find an air cond with turbo cool for the start. In my room I'm constantly adjusting the temperature and modes with my Daikin wifi remote now. So I set it to dry mode then eco mode etc etc. The problem with the Daikin remote is that I can't schedule it to say after 2 hours switch to another mode. Also it never stays on eco mode, I have to manually set that all the time. Main functions that are good to have imo:- 1. Turbo cool 2. Schedule modes 3. Self-cleaning although I'm not sure how good this actually works besides just blow drying the fins - technically, if I can schedule modes, I can schedule the last hour to just fan mode 4. Removable drain pan - this is sooo important. I don't know how to remove my Daikin drain pans! I tried removing the blower wheel but couldn't! It's all so difficult! And because of this, I might need to pay service ppl or buy the wash bags. Over the years, I've bought the wash bags but it's cumbersome. I think Mitsubishi also allows for drain pans to come off easily.... service ppl over the years I have noticed with my air conds have wrecked a lot of my units. Broken covers, drain holes, loose drain pans, etc. It's like they are just as bad as I am but I pay them to be wreck my units. You would think as service ppl they'd know how to handle air conds that they recommend us to buy. 5. Eco mode Inverters don't switch off completely, and can run the compressor at lower speed; whereas non inverter compressor can only turn on / off. A properly sized air cond for a room, will have a proper on / off cycle with a non inverter, for inverter, if your room + heat load calculation gives you borderline between 1hp and 1.5hp, go for 1.5hp for long term savings on energy but if non inverter, then just get 1hp as it will be able to cool down the room with a longer period. Heat load factor is important criteria which many air cond installers don't take into consideration, I have sized two rooms with a slightly bigger air cond and one following the capacity informed by the air cond installer. The two rooms which are sized with slightly bigger units cool better compared to the room with the "proper" sizing as recommended by air cond installer. |
