Check out my latest review of the really cold and unexpected winner – Gree Window-type Inverter Aircon here.
Last year (September 2020), we bought another window-type inverter aircon. This time, it was the LG Dual Inverter model LG LA150EC 1.5HP with WIFI, because the aircon hole of the room it will be placed was bigger and could fit a bigger aircon.
Since the city was on lockdown, we ordered online from Western Appliances via Shopee. Price was about P32,000+ with FREE shipping.
As for installation, we asked our suki aircon cleaner to install it for us since he does a good job, the charge for installation was P1,100. Regular installation fee if bought from mall is sooooo much more expensive!
For the specs, please check the LG official page for this inverter aircon.
LG LA150EC 1.5HP Dual Inverter Window Type Aircon Review
The aircon is used in a room that is currently being used as a home office during the day since people are working from home now for the foreseeable future. At night, the room becomes a semi-entertainment room since it also has the biggest TV, and it’s where we often binge watch our TV series until the wee hours of the morning 🙂 So this aircon is used almost every day for at least 18 hours a day, often longer.
Amazingly Low Power Consumption
So after 6 months of use (September to February), I feel confident enough to give a review on the aircon, and I am very impressed by the electricity savings!
Normally, our electricity bill goes down a little from November to February (around P1,000 – P2,000). I attribute this to the colder weather, meaning our cooling appliances tend to use less electricity.
Now, even with the increased usage of this aircon that is ON at least 18 hours a day, our electricity bill has remained steady, and even dipped a little during the colder months, as expected. If I have to give a rough estimate, I would say that this aircon only costs about P1,000+ (maybe even less!) per month on our electricity bill, even with that much use. Room size is around 15sqm.
That is possible because we are using the aircon on Energy Saver Mode. Take note that this is during the colder months – we will see how it goes when summer comes along, and I will update this after summer 🙂
Energy Saver Mode
We’ve only been using this aircon on Energy Saver Mode, and it is able to cool the room very quickly, as in maybe 10 minutes. We also have blackout curtains on all the windows so I guess that helps keep the heat out, especially during the daytime.
The thing with the Energy Saver mode is that the aircon shuts off when it reaches your target temperature, and then turns itself back on if the temperature goes up. It can be a little bit disconcerting at first, because we would be surprised that the aircon suddenly shut off. We are used to having the aircon humming consistently in the background, so when it shuts itself off and then turns itself back on after 15-45 minutes or so feels kind of surprising each time because there’s no warning when it will shut off, but we got used to it. Still feels a little bit stressful because each time you’re like, “what?! what?! what happened? Brownout?!” and then you realize it’s Energy Saver Mode pala. But it saves money, so okay, haha.
Other Pros and Cons
Wi-Fi
This aircon can be controlled via WIFI. You can install the ThinkQ app on your phone to control the aircon and turn it on/off. Sometimes it’s just easier to either use the remote or to directly push the ON button on the aircon, rather than to get our phone, open the app, and then find the controls. But it is useful when you’re away, not at home, or in another area in your house and you want to turn this aircon on or off or adjust the settings. For example, you want the aircon ON before you arrive in the room so it’s already chilled by the time you get there.
Remote, Timer, Etc…
The aircon comes with a remote control and a remote control holder that you can attach to the wall.
This aircon also has the usual Timer function. You can also adjust the modes, fan speed, etc…
Easy to clean filter
The filter is easy to remove, clean and put back. There’s even an indicator that lights up to tell you that you need to clean the filter. Just take out the filter, wash it under running water to get rid of all the accumulated dust, and put the filter back on the aircon.
No Auto Swing 🙁
This is the only thing I’m sad about this aircon. If you sit in front of the aircon, then it’s great, you get all the cold air “wind”! But what if you’re not in front of the aircon? The aircon is located in one corner of the room. The part of the room that is the other side from the aircon doesn’t get as cold 🙁 It’s cool, but there’s an obvious temperature difference between there and in front of the aircon. The aircon just blows the cold air to the front and I can’t seem to turn the plastic wider to change the direction of the air to the sides. You can only change the wind direction Up or Down.
So to evenly distribute the cold air, we still have an electric fan in front of the aircon. With this combo, even if the temp is set at 24C, it already feels like 20C 🙂
Noise
It’s never going to be as quiet as a split type, but it’s quieter than the Hitachi. I don’t mind it and eventually the hum just fades into the background. As window type aircons go, it’s the quietest one we’ve had.
However, for the first few months, we noticed a rattling sound from the outside part of the aircon. It sounded like someone was shaking spoons & forks. But I don’t notice it anymore. We considered sending it back, but otherwise, the aircon worked well, so in the end we thought it was too much of a hassle to return/replace, especially since we were still on GCQ.
Why did we choose a window type inverter aircon?
The room already has an aircon hole, so it’s just easier to make use of it rather than to cover it up, and then have to make a new hole and do installation for a split type. Also, we are already very used to window type aircons – cleaning the filter every week is easy, unlike with split types that are usually installed very high near the ceiling where I would need to get the ladder every time to clean it. Aircon cleaning for window type is also cheaper than split type.
SUMMARY
This is the most energy-saving aircon we’ve had so far. Even with that much use, it is not using as much electricity as we had feared. After realizing how cost-effective this aircon is, this is the one we have been using more, so we tend to stay in this room more to use the other aircons less 🙂
I am so happy with the low energy consumption that I am wondering if it’s worth it to replace my bedroom’s 16-year old 0.75HP non-inverter LG aircon. Yes, the old aircon is also an LG. The 16-year old aircon is still going strong since I don’t use it as often as I’d like because tipid tipid! (That’s why I tambay in the room with the dual inverter aircon nalang, haha.) The 15sqm room with the old LG aircon gets very cold at night with temp setting at 22C, with electric fan, it feels like 16C sometimes (December to February)! However, if I set it at 23C and upwards it’s not cold enough. Will a 1.5HP dual inverter aircon cost less in terms of power consumption than a 0.75HP non-inverter aircon? Can a technical person tell us in the comments? 🙂 Thank you in advance!
Also, there’s the problem of the size, since the aircon hole is small because the 0.75HP aircon is small (same size as the Hitachi compact inverter aircon though). So if we get another LG LA150EC, there’s the added hassle of having to expand the aircon hole 10 cm wider and 2 cm taller (concrete wall – make bakbak the extra concrete, refinishing it and repainting to make it look good as new). I’m wondering if the purchase cost and the hassle will be justified by the electricity bill savings so I will feel freer to use the aircon more. Why this LG dual inverter aircon? Because I’m more impressed with the energy savings of this aircon than by the Hitachi one and it is also quieter.
What do you think? Do you have other suggestions? Should I just stick with the old aircon until it croaks? Should I just wait for newer aircon models to show up?

Hi! Would you recommend the LG Dual Inverter over Hitachi? How would you compare the two aside from the noise level? Thank you 🙂
Hi Carla, thanks for asking 🙂 Just our personal opinion (since we don’t have any hard data), we feel that the LG uses less electricity, so if that is a major factor for you, the LG is better 🙂 I also feel like it cools faster (but it’s a 1.5HP vs a 1.0HP comparison).
However, we’ve had the Hitachi for a few years now, being used daily, and so far it’s still working great, so proven na siya na durable. The main thing that the Hitachi does better than the LG is the auto swing function (the LG doesn’t have auto swing). This is very useful especially if your aircon is located in a not so ideal place in the room, the auto swing helps the cold air circulate better.
Saan location ng room kung saan nakainstall si LG Daual inverter? Top floor with direct sunlight?
Yes, top floor with 2 windows. May bright sunlight but not harsh direct sunlight. We also have blackout curtains on both windows 🙂
So glad to see your review with LGs window inverter.
It’s kinda new sa market so hooefully it last longer like your hitachi. Im 80% sure that I will purchase this but for some reason can’t stop thinking na basta inverter sirain “daw”
Hi Sherry Rose,
Thank you very much for your comment! 🙂
I think nasa alaga din yan. As long as you take good care of it and don’t abuse it, it should last a while (basta walang factory defect). 🙂
Of course, the newer appliances are not as durable as the ones from decades ago. Honestly, the newer appliances all feel flimsy compared to the old Whirlpool refs of my aunt, and even our old refs of my grandma (forgot the brand name na, basta bought in the 70s / 80s), and our old, old Carrier aircons.
But those old things use a lot of electricity 😀
Anyway, for the aircons, just make sure to clean the filter every week, and have professional cleaning done every 3-4 months if the acs are used all the time 🙂 That’s why I still go for window type – it’s usually easier to clean the filter as it’s usually placed at an accessible height. I’m short so it’s going to be a hassle to climb up and get the filter out of a split type ac every week because split type acs are usually mounted near the ceiling! 😀
Anyway, I’m glad I was able to help you narrow down your aircon choices. Good luck with your new aircon 🙂
I’m actually thinking of buying an inverter aircon soon. I thinking of hitachi since my current aircon is a hitachi non inverter with the same size. But I am considering LG because it has an app, bigger air vent(or whatever it’s called) and around 5k cheaper. LG will require more work though. On paper Hitachi HVQ models should save more money as it has inverter fan, motor and pcb. LG if I remember correctly only has inverter fan and motor. I wonder if the pcb is a big factor though. Maybe the energy saving mode of LG save a lot idrk.
Yep, I think it’s most likely the energy saving mode of LG that’s contributing to the bigger electricity savings 🙂 It turns the aircon off a few times a day for 5-10 minutes so that must be a factor.
I am still considering upgrading my 16-yr old non-inverter LG to the Hitachi inverter mostly because they are the same size. I actually want to get the LG as it’s a newer model, I think, but it’s bigger than my old aircon so the installation is going to be a hassle… Still on the fence until now and haven’t jumped the gun.
Hi Karen,
thanks for your review. We bought a LG LA200EC at Black Friday and installed the air con on the follow Sunday.
I agree with you in all cases you mentioned, especially with the shut off when the energy save mode or sleeping mode is starting.
I’m also super impressed with the very low energy consumption. We use the air con in our 30m² sleeping room.
The only challenge I have is the sleep mode. Do you have an idea how long it needs until the machine is going to shut down when the temperature is reached?
I noticed that one at night the mode was established after 30 minutes and in an other night it needs much longer. First I thought there is something wrong, but after I switched the TV off and went up to bed the air con was in the sleep energy saver mode.
So it looks like everything works as it should…. I’m only a little bit concerned
Hi uwe,
Thank you for your comment 🙂 I’m sorry I have no idea how long before the Sleep mode kicks in. It just happens. Also, this aircon isn’t used very much these past few months because of the colder weather so I can’t give any recent update 🙂
Hi! I just purchased the same aircon recently. Question ko lang is by the time you turn on the AC, you switch to Energy Saver mode ba agad then set the target temperature or fan muna for few minutes? Thank you!
I still do FAN a few minutes although the sales people said no need na for newer aircons hahha 😀
Thank you so much for this very detailed review! Super big help! More power!
Thank you very much for your kind comment, Mabel 🙂 I am so grateful that you found the blog useful! Hope it helps you in deciding on your new aircon.
Lageng nag CH 02 error ung amin, so akala ko sira then bgla n lng gagana tpos sira nbmn then bgla gagana..
Nangyare n din b s inyo to?
Hi, hindi ko alam yung error. Pero sarili talaga siya nag on-off on-off, yun yung feature niya para sa pagtitipid sa kuryente.
Hi.
I am currently searching for a new unit to my old busted carrier split type ac and thinking of getting an LG. Features are enough to entice me but I have no idea how good their after sales is and how easy to deal with their service centers, for maintenance and other things I may need. Do you contact their service center or just go straight to your suki aircon cleaner?
Hi, for cleaning, we just go to our suki aircon cleaner 🙂 So far, we’ve never had to contact LG for problems with our LG aircons. Not even for the old LG non-inverter aircons we’ve had since the early 2000s!
Of those old LG aircons, only one unit remains and it is still working 🙂 The other old LGs have since been replaced with our newer inverter aircons, mostly because they were rusty and overused already.
Hi, what is the best ideal hours per day naka ON si LG premium dual inverter with oinizer?
Nag reorganize kami ng rooms… we don’t use this ac that much anymore kasi that room naging parang guest room nalang siya. I have a new ac review, you might want to check out Gree window inverter ac 🙂

Kamusta consumption during Summer? How much inabot
This is totally failure technology because duel inverter reduces the power input which is not sufficient for air conditioning. Room Temperature doesn’t reduce bellow 29-to-24-degree C. With thermometer we found that cooling effect experienced front and not entire room. The HC mode found to be working only on high speed FAN MODE with 10% cooling, compressor outside and condenser in internal unit doesn’t work effectively.
Instead of cooling entire room you get cooling effect only in front of swing flaps, that too with high-speed fans. Those who are convinced with the idea of Low Power consumption and low electrical bill, they are likely to get frustrated because this AC works like a cooler and not air conditioner.
I have purchased this AC from local dealer and not from Amazon. This is just for information who go through reviews before they purchase.
I wasn’t very happy, in fact I never been so disappointed than buying LA15OGC dual interverter unit. Hindi siya lumalamig ng maayos to think na maliit lang ang kwarto namin. Natapat pa ko sa rude service tech at customer support ihohold ng napakatagal ang tawag mo.
hello! do you put your ac po on 40% energy control mode? i live in a dorm unit po kasi (15sqm) to be exact and dalawa lang po kami sa room, we usually have our ac turned on 8hrs max na po a day. but our electricity bill is usually 1.4k-1.6k but we have other appliances po, pero inverter din like the fridge. feeling ko lang po kasi the bill is too high for 2 persons hehe or is it justifiable po ba? thanks po!
We actually have not used this LG ac in a while, only rarely when we have guests over since we moved the home office to another room.
But 1.4 – 1.6 k sounds about right if you have an aircon and also a ref, plus other things like TV, computers, electric fans, electric kettle, rice cooker, lights, hair dryer, etc… The bulk of the consumption will be the ref and aircon though, and that sounds about right.
You can check the Meralco appliance calculator to get an idea of how much it costs to run your appliance. You can choose the type of appliance, then how many hours per day, how many days per month, and the app will calculate it.
I don’t know how many HP your aircon is, also, if your dorm has a big window or is sun facing, if insulation is good or bad, etc… those factors will affect how much electricity the ac consumes.
Generally though, an inverter 1 to 1.5 HP ac running about 9 hrs a day every day will cost around P600-900 per month from what I remember from the Meralco app.
Regular size inverter ref naman will cost around P600-900 per month and higher depending on how big it is, according to the sales people sa appliance stores.
There is also a significant increase during the summer months. Like, for us, almost everything just being the usual activities, Meralco bills during summer months can go up almost twice, we’re not doing anything differently. Then come back down to near half again during the colder months until Feb.
Hope this helps 🙂
