Hitachi Window Type Air Conditioner (Kompakt) Review - Karen MNL (2023)

since I did mineHitachi Air Conditioner Vs. Carrier InverterIn the post, some of you asked for a more comprehensive review of the Hitachi inverter window air conditioner.

I also have a review of our new LG 1.5 Dual Inverter Aircon here:

I found an unexpected air conditioner, check it out here:Inverter air conditioner with green windowVery cool and much cheaper than the others!


The model we have isRA10HVQ. The first one we bought was a few years ago when this model was the only window type inverter air conditioner available that fit our little "air conditioning hole" in the wall. I don't know what it's called, so let's just call it the air conditioning hole.

It was recommended to me by a friend of my sister. Hitachi replaced an LG 0.75HP AC (that's why we have a small AC hole in the wall). The room in which it is located is about 12-15 square meters. Thankfully, the Hitachi compact fit perfectly into our climate hole, so we didn't have to do any major installation work.

Check out this guide on which air conditioner you should get based on room size:

We bought the Hitachi for 26,000 pesos at the time and it came with a standalone fan. The table fan brand is Union, it is beautiful and has a remote control. It still works like this until nowit is durable. It's not thin.

When the air conditioner was delivered it came in a box and we were on our own to install it. Thankfully they pointed us to this installer who compared it to previous installers we had who just pushed foam around the AC to seal the hole (width only straight). More on that below.


I won't go through the technical specs because I'm not an expert on any of that. You can google the specs. I'll check it out as a user 🙂

This is how it looks from the front. The air conditioning is off, but you still see the temperature. I think it's room temperature.

You push the "door" up and down to open it. When you open it, you will see the filter/screen. Sorry about the dirty filter, I really need to clean it. You push the handles and take it off and clean it with water and maybe a little mild soap when it gets dirty. I like that the filter is easy to get and easy to return.

In fact, this is the first time I've noticed the yellow foam on the left side. It's usually not visible, but the camera angle picks it up.

The device feels solid although there is a styrofoam section inside but everything else appears to be metal.

This is what it looks like out there. It's a little dirty but that's real life 🙂 My uncle likes to put a strip of cloth on top of all our air conditioners to help drain the water better and underneath there's a bucket to collect the water used to water the garden and cleaning can be recycled exterior floors etc…

It comes with a remote, but it doesn't have a remote holder, so we just attached it with velcro.

Here are some photos of the installation (with sealant):


With newer air conditioners, there is no need to switch to fan mode first before switching to cooling mode.

We usually set the temperature to 22 or 23 C to save energy. It takes a while for the AC to cool down the whole room, but I think it depends if the AC is clean or not. If it has just been cleaned, the air conditioner will cool the room very quickly. If the air conditioner is dirty, it will take longer. Make sure all windows are closed and all holes are sealed. It usually takes 1-2 hours at night to reach temperature (starting at 30 or 29 °C to drop to 23 °C).

In order for the room to cool down faster, we turn on an electric fan to help circulate the cold air. Obviously, a less crowded space cools faster because there's less stuff to cool. Also, reduce heat-generating items in the room to help it cool down more quickly: turn off lights when you don't need them, etc.

However, once the desired temperature is reached, it is quite stable. Even if I set it to 23°C around 4am, I'm too cold. The A/C thermostat says 23C but it feels like 16C!

On very hot summer nights, I still use an electric fan to keep the room cooler, although I think the problem is that the air conditioner is dirty and needs cleaning. I turn off the fan when it's cold.

BUT, if I turn on the AC, turn off the lights, leave the room, close the door, leave it alone, the room cools down faster.For example, if I start at 30C, I come back about 20 minutes later and the room is cold at 25C. So if you want it to cool down faster, you can.

Hitachi Air Conditioner No. 2 stays at 25°C. It's a nice, comfortable temperature and every time I step into this room, it's always nice and cool. This one rarely comes out, soit is durable, is almost 2 years old and operates 24 hours a day, 7 days a week. It just needs to be cleaned more often.

To use

In terms of use, we have no problem with them. The remote has to be pointed at the air conditioner to work, that's all. Our previous LG air conditioner remote works even if you point it elsewhere.

The air conditioner has a timer function of up to 24 hours, you can adjust the temperature according to your needs and the air conditioner will work to reach that temperature.

I usually set it to Auto and Auto Swing. We never fix them, we just clean them.


You will hear the typical sound of a window air conditioner, although not as loud as previous generation air conditioners. Sounds like air is being sucked in or out, a faint hiss. There should be no rattling noises. If you hear a squeaking or rattling noise, have it checked or replaced if it's new.


When we purchased our first Hitachi inverter air conditioner, our Meralco bill was reduced by almost 1/3. Our electricity bill was 2/3 of what it used to be.

After we purchased our other inverter air conditioners, it became more difficult to estimate how much we had saved because we typically used them longer knowing they were cheaper to run. Whereas previously we programmed it to stop at 6 or 8 o'clock, this time we're going to let it run at 12 o'clock.

Even with the additional usage and rising prices from Meralco, our electricity bills have remained lower than they were before we bought our first inverter air conditioner 2 years ago.

The amount you save depends on how much you used your non-inverter AC power before switching to an inverter. But switching to inverter definitely was a big factor in lowering our electricity bills. If I had to guess, I'd say maybe P2-3k savings on air conditioning per month.


The filter needs to be cleaned regularly, perhaps once a week. At least once per month. It depends on how dusty your air is. Just remove the filter, clean it carefully and replace it.

When you remove the filter you will see some metal fins and if they look dirty it is time to have your air conditioner cleaned by a professional. If you feel like your air conditioner isn't working as well as it used to, it's probably time to clean it too.

Ideally, the air conditioner should be cleaned frequently. A dirty air conditioner is very inefficient and consumes more electricity.myth game. We clean ours every 3-6 months but the other AC gets dirty very quickly so ideally it should be cleaned every 2 months. However, sometimes it's a little awkward to call in for a cleaning appointment, wait, and end up at home during the cleaning process.still. The process of cleaning air conditioning systems takes between 30 minutes and an hour. Try to clean the air conditioners on the same date to make it less work for everyone.Cleaning costs are around P450-500each for window air conditioning. They often give you a discount if you clean more air conditioners.

They should provide an area where they can do the cleaning, e.g. B. on the sidewalk, garage, etc., preferably somewhere near a water tap and where dirty water can drain.

You can clean the air conditioner yourself if you know what you're doing and have a pressure washer. J cleans his own air conditioner and I was surprised that he could load all the air conditioners himself. It's easier to do it yourself than to code and waitHitachi Window Type Air Conditioner (Kompakt) Review - Karen MNL (11)Your air conditioner is also a Hitachi. His old LG A/C died and he bought this Hitachi based on our previous experience with them, no problems naman. As far as I know, his Hitachi air conditioner has not had any problems, and his electricity bill has also dropped a lot since he switched to inverter.
