The Switch to Inverter Air Conditioner


After almost a year of contemplating on the switch to inverter air conditioners, we finally decided to buy one last March 4, 2017. We got the Kolin 1-hp window-type inverter aircon (KAG-110RSINV model) after considering other options from Hitachi, Gree, and Carrier.


Why Kolin?

We initially thought of getting the Hitachi brand, but realized its air vent was small. The location of the air vent (left side of the unit) also became a concern because we will install it in the leftmost side of our room (we thought that air flow coverage would be somewhat limited). We then saw Gree as an alternative, but it's a bit expensive. Further research showed that Gree air conditioners has the same manufacturer as Kolin, Mabe, Sharp, American Home, and Fujidenso. We found no reason to pay more for practically the same product offered by the other brands mentioned, so Gree was also scratched from the list. Carrier, on the other hand, was the most popular in my list but also the most expensive. According to the person who assisted us, when it comes to inverter aircons, brands don't really matter much (the premium you'll be paying is for the brand name and customer service). I did a quick research on the Kolin window-type inverter aircon, and it appears to be the bang-for-buck and proven effective option, albeit a high pitch / hissing compressor "noise" reported by some users (but noise level is subjective per user, and most said that it's something that you can get used to after some time).

Kolin S-Series Inverter Aircon

In the end, we gambled on Kolin. Since window-type aircons have only been around for a few years, Kolin's reliability (in terms of how long it will last), is something for us to find out.


Why didn't we get the split-type instead?

Although split-type inverter aircons are less expensive than window-type models, their maintenance cost is more expensive and cumbersome, based on our experience with the Daikin split-type aircon that we have in another room. Installation is also a hassle (especially if you don't have provision for split-type aircon) and comes as an additional cost.


Is Kolin really noisy?

After a week of using the Kolin inverter aircon, I haven't noticed the high pitch / hissing compressor "noise" reported by some users. Either Kolin has already fixed it or I'm just used to aircon "noise". Or maybe the "noise" they're referring to is the sound of the compressor after turning the unit on.

The first time I turned on our Kolin inverter aircon, I immediately noticed that it's not as "quiet" as the Condura 0.75-hp non-inverter aircon we had installed previously. I just attributed the difference to the bigger compressor (1-hp vs. 0.75-hp). But the good thing is, after the room had achieved the specified temperature, Kolin's "noise" was already comparable to Condura's.

Out of curiosity, I downloaded a noise meter for iPhone called Decibel 10th to compare the "noise" coming from our 2 aircon units. Though the app may not be 100% accurate, at least I have an objective basis for the comparison.

The picture below shows the ambient noise level in the room with the Condura aircon turned off. With a reading of 54 dB, the app compared the noise level to "any quiet street".

Kolin Inverter Aircon KAG-110RSINV Noise Level Comparison

The next picture shows the noise level of our Condura aircon that has been running for around 30 minutes. Thermostat was set to around 80% cool with fan speed set to low. With the iPhone placed around 6 inches away from the aircon unit, a 72.4 dB reading was recorded. According to Decibel 10th, the level is comparable to the average noise inside a car.

Kolin Inverter Aircon KAG-110RSINV Noise Level Comparison

Now, let's check the noise level of the Kolin aircon. For this test, I tried 3 different settings. The picture below shows the noise level with the thermostat set to 24 ℃ and fan speed set to low. Surprisingly, the reading was only 65.5 dB, Kolin is quieter than the Condura! Decibel 10th compared the noise to "average normal conversation".

Kolin Inverter Aircon KAG-110RSINV Noise Level Comparison

For the next setting, the thermostat was still at 24 ℃ but the fan speed was now at medium. The reading was 67.1 dB, still comparable to "average normal conversation", and still quieter than the Condura. 

Kolin Inverter Aircon KAG-110RSINV Noise Level Comparison

For the last setting, the thermostat was still at 24 ℃ but the fan speed was now set to high. With a reading of 69.9 dB, the noise level is still comparable to "average normal conversation", and still quieter than the Condura!

Kolin Inverter Aircon KAG-110RSINV Noise Level Comparison

Based on the tests conducted, Kolin is not that noisy after all. The "noise" after switching it on may be louder, but definitely tolerable. You can expect it to be quiet after a few minutes. 


Are we satisfied with Kolin?

So far, we have no regrets in getting the Kolin brand. We noticed that it has a strong fan which helps in cooling the room faster. As advised, in order to achieve greater power savings, the thermostat setting should be 22 to 25 ℃. The 1-hp unit that we got is just right since we're already ok with 25 ℃ setting (sometimes, my wife even sets it to 26 ℃).

We're yet to find out the monthly savings it would bring. It's interesting to know if a 1-hp inverter unit will be more energy efficient than a 0.75-hp non-inverter type. I''ll give an update in 2 months to report on our power consumption.

We're hoping that this Kolin inverter aircon will really give us significant power savings and last at least 10 years to make the ₱24,000 "investment" worth it.


***Update (July 19, 2017)***

I checked our condo billing statements (December 2016 - July 2017) to compare our power consumption before and after the switch to Kolin inverter aircon.

Our average consumption based on the 3 months billing prior to the switch (December 2016 - February 2017) is 409 kWh.

After the switch, our power consumption is as follows:
March 2017 - 328 kWh
April 2017 - 338 kWh
May 2017 - 381 kWh 
June 2017 - 376 kWh

So far, so good! Am I still satisfied? Definitely! Our daily aircon usage has really increased in the past few months, yet our power consumption managed to stay below 409 kWh.

Something that's worth noting is that, the 3 months prior to the switch can be considered "cold months" since it's during the Christmas season. Supposedly, our power consumption during those months is lower due to decreased aircon usage. Our switch to inverter aircon happened during the summer season.

Lastly, it should be noted that our previous aircon was only 0.75 HP; even though we switched to a 1 HP unit already, our power consumption is still lower than before.


I'm interested to know the savings that can be achieved by the switch from 1 HP non-inverter to 1 HP inverter aircon. Got experience to share? Post it on the Comments section below. :)

    1. Hi Khenzzie. Our latest condo billing included 14 days of use of the Kolin inverter aircon. Our usual power consumption is more than 400 kwh per month, but in the latest billing, we just consumed 328 kwh. :)

      Maybe it's too early to tell, but so far so good. I'm looking forward to our power consumption for the next 2 months.

    1. On the average, 13 hours a day.

      By the way, the power consumption I mentioned above also includes consumption from other electric appliances such as rice cooker, air fryer, electric stove, electric oven, water heater, front load washer and dryer (which we use around 4 times a week for 4-5 hours per complete wash-dry session), and steam iron.

    1. Hi Vic. Just received our condo billing. Power consumption for March 18 to April 17 is 338 kwh. It increased by 10 kwh based on the previous month's billing, but I was already expecting the increase since my wife often used our electric oven during the period plus we used the other non-inverter aircon in the other room from time to time (the Condura aircon I showed above). I'm happy to learn that our power consumption just increased by 10 kwh despite of the additional use of electric appliances, and still below our average power consumption of 400 kwh per month.

      I'm definitely looking forward to more savings in the coming months. :)

  6. hi. very informative and well-written review. :)
    I am planning on buying this Kolin model versus the HITACHI RA-10HVQ 1.0HP inverter.
    Did you notice any change in the sound levels? Or the hissing sound reported by some other users?
    How about their customer service? Did you have any encounters with their after-sales office yet?
    Lastly, did they offer free cleaning services (eg. for the first year)? And if you don't mind, may I know where you bought your unit?
    Thanks a lot!

    1. Hello, thanks for the kind words. :)

      I didn't notice a change in the sound/noise levels. I also haven't tried contacting customer service/after sales office because my unit is still working perfectly. I may need to call them soon, however, to check accredited suppliers who can clean my unit.

      With regards to the free cleaning service for the first year, unfortunately, I didn't receive any. It's fine, though, since I was given a good discount when I got it. Got my unit from Robinsons Appliance Center in Robinsons Pioneer.

      Thanks for visiting and reading my blog. Good day! :)

      Our previous Condura aircon (the one replaced by this Kolin unit) is just 0.75HP.
      1HP should already be enough for your needs. We seldom go below 23 deg because it's too cold already (oftentimes, it's just at 25 deg). :)

    1. Hi, I just like to confirm, your room is 10m x 18m? If yes, that means the total area is 180 sq. m. A 1.0HP aircon would not be enough. I suggest that you have your place surveyed so a proper recommendation on aircon size can be given (most likely, you need the 3-tonner type or multiple split type units).

      Regarding installation fee, it depends on the promo of the store. But usually for split type aircons, may bayad talaga.

Just a few tips to ask, do you use the dry mode function of your Kolin inverter? If yes, when and for how long do you use it?

    I made initial research but I would still want to hear from an actual brand user. :)

  27. Hi sir! :) Thanks for this wonderful article. It was really helpful. I also got the same unit. Just curious, did you take out the plug from the drain hole and let the water naturally drip out? I did. only to find out after 1 month of installation that the unit works best if you leave the rubber plug on since it has the NO DRIP design. The manual says taking out the rubber plug and installing the drain pan may have a little effect on the performance. What do you think?

    1. Hi, thanks for visiting my blog. :) I removed the rubber plug. The last time I used a no-drip aircon unit (i.e., the one replaced by this Kolin unit), sa loob nag-drip yung water na naipon! :P Also with the rubber plug attached, you'll sometimes hear water splashing inside the unit (based on feedbacks I've read from other users).

  28. What a coincidence! I was looking for reviews of Kolin AC, particularly the one we bought, and I stumbled upon your blog. Turns out we have the same exact model. I'm hoping that this is a good buy! https://image.prntscr.com/image/hbR2lidBTYeQvilPO1zWfg.png

    How's your unit now, by the way (almost a year from when you purchased it)? How many times did you have it cleaned? What's your latest electricity bill? Has it been consistent with the 'promised' savings?

    For comparison, we used to have a Condura 1.5HP Non-inverter AC (which we sold due to high electricity cost), and our average monthly electricity bill was around 6K.

    3. Regarding the 0.75hp non-inverter unit, like what I mentioned in my post, I used a Condura 0.75hp non-inverter unit previously. When I upgraded to a 1hp Kolin inverter unit, my power consumption decreased even though I'm now using a bigger unit (1hp vs 0.75hp). If you're going to use the aircon for at least 6 hours (continuous usage), I suggest dagdag ka na lang and get the inverter type. Pero kung tipong 3 hours lang, ok na din non-inverter type (check the Energy Efficiency Ratio when comparing non-inverter units). Hope this helps. :)

    4. Regarding the Kolin unit being noisy, it never became an issue to me. That's also the reason why I wrote this article and showed the dB reading as well. Good luck on your decision. :) Whatever brand you choose, as long as it's an inverter one, you'll surely get power consumption savings. :)

    1. In my case, there is a noticeable difference in the "noise" when the unit goes automatic. Maybe nasanay ka lang sa almost noiseless operation ng split type? We'll know when your electricity bill arrives. Please keep me posted.

      Delete
    2. The compressor has variable speed and you can't hear the compressor noise. It slows down when it reaches the desired temperature. The only way to observe is visually. Makikita mo pag steady, hi-speed, less vibrations. Pag may zig-zag motion, slow speed na, noticeable ang vibration pero tahimik parin.

    Replies
    1. If inverter to inverter, theoretically lower yung consumption ng 0.75hp unit. But if it's 0.75hp non-inverter vs 1hp inverter, mas matipid yung 1hp (just like in my case).

  43. hi, did everyone here used the drain pan? the agent from where i bought it told me not to use it... he said that it is recommended to keep the plug... it will help the evaporator to be cooled by the water splashing on it specially that its summer... is it true?

    1. They said that it's better to keep the plug on. But my bad experience with a dripless unit made me decide to remove the plug instead. I still experienced the savings and still happy with my unit even with my current setup. :)

  44. Hi, i'm also doing some research right now on whether to go inverter or stick with conventional, non-inverter AC unit. i didn't get to read all the comments, but i'd like to know if it would be more economical to switch to inverter-type if i only use my AC when i sleep at night with the AC unit usage at an average of 8 hours? your reply would be much appreciated.

    1. I suggest that you go with the inverter unit. 8 hours of daily usage should be enough for you to experience the savings.

  46. Hi,

    Im using kolin, but the split type (1.5), my normal consumption not using an aircon(before purchase) is around 1.5, now it just double my consumption, and my normal bill is around 3.5. that includes 2 electric fan, 1 32inch tv, 1 49 inch 4k TV, 6 FT fridge(non-inverter), top load automatic washing machine(6kg) used 2-3 times a week, coffee maker(single cup), flat iron(usually 2-3 times a week, i dont iron my clothes by my wife and kids do). and also use of over every now and then. all of my bulbs are LED. my aircon termostat is set to 25, but lately we've set it to 23. our room window mostly receive heat from the sun , but usually we cover it with thick curtain, since Im on night shift and need a substantial blockade from light. our latest bill just reach 400kwh+ amounting to ~5k, due to simple change of termostat(25 to 23)

  47. Hi. We're using kolin s series 1.2hp..were shifting to inverter. But confused on getting 1.o or 1.5. Per features, our current unit's cooling capacity is 11,200. But with the inverter 1.0hp thats only 9600. But the wattage is quite far from 960watts to 760watts. The inverter 1.5hp wattage is 1080 watts which is higher than my current ac. What can you suggest. Thanks

    ReplyDelete
    Replies
    1. Get the 1.5hp. your compressor speed will drop once you reach the desired temperature. The tendency of an underpowered compressor is to run at full power, negating any savings.

  50. Hi, I've heard that to be able to save using the inverter type aircon, we must use it for a minimum of 8 hours? Is that true? We only use our inverter type aircon for 4 to 5 hours everyday. Not everybody uses aircon for 8 hours and more. We sleep late and wake up early. Does it mean that there is no savings if the inverter type aircon is used less than 8 hour? Would appreciate your feedback on this. Thank you.

    1. Much better if you can provide actual dimensions of the room. We need the floor area to determine kung ilang hp yung dapat na kunin. Pag masyado kasi malaki yung room, baka di kayanin ng 1hp unit (worse, 0.8hp). From what I know, 1hp ang lowest ni Kolin.

  52. Torn between Condura and Kolin 1.5HP Inverter. Actually andito ako sa Bodega sale ng Condura ngayon, haba ng pila. Tip lang for buyers, dito sa Bodega Sale Class B ang benta nila meaning yung may mga slight cosmetic damages. Then sa Kolin, sa Main Branch nila sa may Magallanes, they gave me 18% discount sa SRP nila Class A aircons. Kaya ngayon, I'm still torn should I get the Class B from Condura or Class A from Kolin. Yung discount na makukuha ko from Kolin halos kapresyo ng Class B from Condura... Only a few hours left to decide...

  58. I bought my Kolin 1HP window type inverter last April 30. When our bill came last May 15, it just went down by Php 200. So I thought maybe because we still used the old non inverter aircon for the 1st 15 days, and used this new one for the 2nd half. So i waited for another month to see if it was really cost efficient. When i got my bill last june 15, WOW... it went down by almost 2k. It's really true... inverter aircon works well indeed and is very cost efficient. Im using mine for about 12 hrs on weekdays and 15 to 18 hrs on weekends (23-24c temp), and my sister uses her own (1.5hp window type kolin inverter) for about 8 hrs everyday (22c temp).

  66. We had the Kolin 110rsinv inverter window aircon since july 2017. It worked very well for around 9 months or so. We had it serviced last july 2018 because it won't turn on, and just makes a clicking sound and blinking Led when powered on. It also had EE code in the LED display. The repair men simply replaced the part/box where the Led display is. It worked fine for a few days but the problem returned. The unit would suddenly turn off, make the clicking sound, turn back on again, turn off, and so on. Sometimes the unit would work for 10hours+ without issues, so we held off having it checked.
    This went on for almost 3 months. Today i have repair men back at my place so they can check. I will try to update with their findings and recommendation.

    1. The repair men said the board with the leds were loosely connected, which might have caused the unit to blink due to power problems. We'll monitor and hopefully that indeed was the only problem.

  67. Great review and I really like the fact that you got really detailed pagdating sa sound levels! I initally wanted to purchase this but ended up getting the Hitachi despite the slightly higher price tag (RA_10HVQ) kasi Hitachi talaga ang pioneed ng window type na inverter AC and di ako nag sisisi.

    Concern ko rin noon is yung louvers nasa left side kasi yung output ng air kasi sa left most part ko din siya ng room iiinstall pero since it can really angle towards right side and nakita ko yung build quality I went for it.

    High pressure and high air discharge rate despite the small outlet and the reason for this is because Hitachi uses a larger evaporator/condenser for better heat transer kaya mas mahal rin (13.X EER I think). Not affiliated with them I just want to share my experience with this model.

    It is really cool-running, quiet, well insulated, and their after-sales support is impeccable. Those who want to go for it di kayo mag sisisi, i'd like to share my review po pala sir glenn if okay lang:

    1. Auto, Cool tapos 25C yung usual na setting nung amin. Check mo kung may gap sa door, windows and kung may iba pang butas sa walls. Makaka-affect kasi yun sa consumption (pag hindi na-m-maintain yung lamig inside the room, mas matagal magtatrabaho yung aircon mo, which means mas malakas sa kuryente). What you can try is i-fix mo na lang sa low (or medium) yung fan speed (i.e., hindi automatic).

I am worried about the maintenance issues of having the split type since I have heard insects and lizards might get inside the outdoor unit and mess the circuit board inside. Does this happen to window type too? Does insects get inside the vents? I would also like to hear your maintenance issues on having the split type. Thanks in advance sir!

    1. We've been using window type aircon since 1990 (the bulky Carrier units) but we've never experienced insects getting inside the unit. I guess it depends on the location, but in general, insects going inside the unit shouldn't be a concern. :) In terms of maintenance, cleaning window type is easier since you can easily pull it out. For split type, the indoor unit will be cleaned in its current location (so expect them to pull the water hose and use plastics to catch the water coming from the unit while it is being cleaned). So far, no issues with my window type and split type aircons. :)

  92. Thanks for your informative blog.

    I have a non-inverter Kolin 1hp that I have used for almost 4 years. I clean the front filter on a regular basis and vacuum the cooling fins when the filter is removed. I have never had any additional cleaning performed as I believe "If if ain't broke, don't fix it."

    I have considered switching to an inverter type Kolin to reduce our electric expense, but when I read that people are setting their units at 22 or 23 to maintain a comfortable temperature...I am concerned about the cooling efficiency of the inverter type Kolin.

    Normally, I set our non-inverter Kolin at 28 or 29 unless it is a very hot day and then never below 25 to obtain a comfortable temperature. So if I would switch to an inverter type Kolin and have to set it at 22 or 23 I think it would run longer to obtain a comfortable room temperature and negate any energy savings.

    Where did you discover the data that "Gree air conditioners has the same manufacturer as Kolin, Mabe, Sharp, American Home, and Fujidenso?" I ask because when I saw the remote for the Gree it was identical to my Kolin remote. I asked a seller of the Gree on Lazada if Gree was made by Kolin and he replied, "No sir we are different than Kolin." Maybe the remotes and compressors are identical, but Gree has some different features than the Kolin...so I am curious.

    I could buy a Gree 1hp inverter type for P22,761 and have it shipped to Palawan for P953 for a total of P23,714 or buy the Kolin 1hp inverter type at our local Robinson's Appliance for P27,995 (possibly a discount for cash) and pay them P300 to deliver it to my house for a projected total of P28,295.

    The price difference of P4,581 is a consideration. My concern would be the shipping after watching airport ramp employees throw cargo off the airplane and the delivery drivers who can also handle cargo in a rough manner.

    Any thoughts from all readers will be deeply appreciated.

    Salamat po.

      Hi! the you can set the temperature as desired, the optimal energy savings and thermal comfort is between 24 to 26.4 degree Celsius,for the inverter the temperature has very minimal deviation while on non inverter temperature tend to have a wide deviation before the set temperature(too cold or too warm while on inverter its on the middle)

      We are using KAG-150RSINV 21sqm 9 hrs with 24-26 degree Celsius sleep mode average consumption 2.50kWh previously using KAG-160RS 6-7 hrs average consumption 4-5kWh.

      As for the brand I think internals are made by gree but they change the front cover(rebranding as Kolin)

      You can try Gree brand and share your experience or stick with Kolin, it depends on your preference temperature/brand... :)
