Since I did my Hitachi vs. Carrier Inverter Aircon post, some of you have been asking for a fuller review on the Hitachi Window Type Inverter Aircon.
HITACHI WINDOW TYPE INVERTER AIRCON 1.0 HP
The model we have is the RA10HVQ. The first one we bought was a couple of years ago, when this model was the only one available window type inverter aircon, and which can fit in our small “aircon hole” on the wall. I don’t know what it’s called, so let’s just call it the aircon hole.
It was recommended by a friend of my sis. The Hitachi replaced a 0.75HP LG aircon (that’s why we have a small aircon hole on the wall). The room it’s in is around 12-15 sqm. Fortunately, the compact Hitachi just fit our aircon hole exactly so we didn’t need to do any major installation work.
You can check this guide on what aircon to get depending on room size: https://www.doe.gov.ph/sites/default/files/pdf/consumer_connect/properly_sized_room_air_conditioners.pdf
We bought the Hitachi for P26,000 at that time, and it came with a free stand fan. The stand fan brand is Union, it is nice and has a remote! It still works until now, so matibay naman. It’s not flimsy.
When the aircon was delivered, it came in a box and we were on our own when it comes to installing it. Fortunately, we were referred to this installer who did a better job compared to the previous installers we’ve had who would just shove foam around the aircon to seal the hole (bara-bara lang). More on that below.
I’m not going to go through the technical specs, because I’m not an expert at any of that. You can just google the technical specs. I’m going to review this as a user 🙂
This is what it looks like in front. The aircon is off, but you’ll still see the temperature. This is the temperature of the room, I guess.
You push the “door” at the top and bottom to open it. When you open it, you’ll see the filter / screen. Sorry about the dirty filter, I really need to clean it. You push up the handles and take this out and clean it with water and maybe some mild soap whenever it’s dirty. I like that the filter is easy to get to and easy to return.
This is actually the first time that I am noticing the yellow foam on the left side. It’s not visible normally, but the camera angle picks it up.
The unit seems solid, although there is an area inside that is styro, but all the other stuff seems to be made of metal.
This is what it looks like outside. It’s a bit dirty, but this is real life 🙂 My uncle likes to put a strip of cloth on all our aircons to help the water drip down, and there’s a pail under it to collect the water that can be recycled for watering the garden, cleaning outdoor floors, etc…
It comes with a remote, but no remote holder, so we just put velcro.
Here are some pics of the installation (with sealant):
With the newer aircons, there’s no need to go to Fan mode first before going to cooling.
We usually set the temperature to 22 or 23 C to save on electricity. It takes a while for the aircon to cool the entire room, but I find that it depends on whether the aircon is clean or not. If it has just been cleaned, the aircon cools the room very fast. If the aircon is dirty, it takes a longer time. Make sure all the windows are closed and that any holes are sealed. Generally, it takes us 1-2 hours at night to reach temp (starting from 30 or 29 C to go down to 23 C).
To make the room colder faster, we turn on an electrical fan to help circulate the cold air. A less crowded room will cool faster, obviously, since there are less things to cool down. Also, reduce heat-generating items in the room to help it cool faster – turn off lights if you don’t need them, etc…
However, once the desired temp is reached, it’s pretty stable. Even if I set it at 23 C, by around 4am, I am very cold. The aircon thermostat says 23 C, but it feels like 16 C!
On really hot summer nights, I still turn on an electric fan to help make the room feel colder, although I feel that the problem is because the aircon is dirty and needs to be cleaned. I turn off the fan when it gets cold.
BUT, if I turn on the aircon, turn the lights off, leave the room, close the door, leave it alone, the room cools down faster. Like, if I start at 30 C, I come back around 20 mins later and the room is cool at 25 C. So if you want it to cool faster, you can do this.
Hitachi aircon #2 is kept at 25 C. It’s a nice and comfortable temperature, and whenever I enter that room it’s always nice and cool. This one is rarely turned off, so matibay naman, it’s almost 2 years old and it’s turned on 24/7. It just needs to be cleaned more often.
In terms of usage, we don’t have any problem with them. The remote control needs to be pointed at the aircon to work, that’s all. Our older LG aircon remote will work even if it’s pointed somewhere else.
The ac has a timer function up to 24 hours, you can adjust the temperature to what you like and the ac will work to reach that temp.
I usually just set it on Auto and on Auto Swing. We’ve never had any of them repaired, just cleaned.
It will have the typical window-type aircon noise, although it’s not as loud the older generation aircons. It sounds like air being sucked in or pushed out, a gentle whoosshhhhh. There shouldn’t be any rattling sounds. If you hear any high pitched sounds or rattling, have it checked or replaced if it’s still brand new.
EFFECT ON ELECTRICITY BILL
When we got our first Hitachi inverter aircon, the effect on our Meralco bill was an almost 1/3 slash. Our electricity bill became 2/3 of what it used to be.
After we got our other inverter aircons, it became harder to estimate how much we saved, because knowing that they were cheaper to run, we tended to use them longer. Whereas before, we timed it to stop at 6 hours or 8 hours, this time, we let it go for up to 12 hours.
Even with the added usage and the increase in Meralco prices, our electricity bill remained lower than before we bought our first inverter aircon 2 years ago.
How much you save depends on how much you were using your non-inverter AC before you switch to inverter. But switching to inverter definitely, definitely was a big factor in reducing our electricity bill. If I had to guess, I would say maybe P2-3k savings per aircon per month.
The filter should be cleaned often, maybe once a week. At least once a month. It depends on how dusty your air is. Just take out the filter, gently clean it, then put it back.
When you remove the filter, you’ll see some metal fins, and if they look dirty, it’s time to have the aircon professionally cleaned. If you feel like the aircon is not performing as well as it used to, it’s probably time to have it cleaned, as well.
Ideally, the aircon should be cleaned often. A dirty aircon is very inefficient and uses up more electricity daw. We clean ours around every 3-6 months, but the other aircon gets dirty very quickly, so that should be cleaned every 2 months, ideally. However, sometimes it’s a bit of a hassle to call for a cleaning appointment, then wait at home during the cleaning process, and make bantay. The cleaning process takes around 30 mins to an hour per aircon. Try to have the aircons cleaned at the same appointment so it’s less hassle for everyone. Cleaning costs around P450-500 each for window type aircons. They usually give some discount if you clean more aircons.
You’ll need to provide an area where they can do the cleaning, like in the driveway, garage, etc… preferably somewhere near a faucet and where the dirty water can drain.
You can clean the aircon yourself if you know what you are doing and have a power washer. J cleans his aircon himself and I was shocked he could carry the whole aircon by himself. It’s easier daw to just do it himself than to schedule and wait His aircon is a Hitachi just like this one, too. His old LG aircon died and he bought this Hitachi because of our experience with them na so far, no issues naman. His Hitachi aircon does not have any problems, as far as I know, and his electricity bill was also cut by a lot since he switched to inverter.
This post was not sponsored by Hitachi, sana it was It just so happened that my sister’s friend recommended it to us, we tried it, and then refer refer and that’s how we all ended up with this aircon.
- compact size can fit into smaller ac holes
- durable (matibay naman), we’ve never had any of them repaired so far, even with constant daily use
- it was the most affordable window-type inverter aircon at the time
- if people are in the room and lights are on (LED), it takes 1-2 hours before it reaches desired temp; however, with no one in the room, lights turned off, it took less than 20 minutes to go from 30 C to 25 C
- 1.0 HP is the lowest HP available, there’s no 0.75HP
- no accessories included: no remote holder, brackets, etc…
ABOUT THE INSTALLATION
For those asking about the installation, we got e-5 Air-Condition & Electronics Service Center, # 254-8361, 711-8506, 711-8987. They are located in Sta. Cruz, Manila. We ask for Daniel.
Mounting (salpak), P650
Brackets, around P450
Sealant, around P250
Any adjustments like making the hole size bigger, P250 (they have a grinder)
Those were the prices for our location, they might charge higher if you are located farther.
We don’t buy aircons that often, but when we do, they are the ones we get because their work is much more professional looking than the ones we got before na mukhang bara bara talaga and only use L-brackets.
Check that the aircon is angled slightly downward at the back, so that any water that condenses can drip down.
I hope you enjoyed this blog post. Please feel free to leave a comment below, I love hearing from you!
