Last year, we bought a 1.0 HP Carrier Inverter Aircon (Window Type). We originally planned to buy the cheaper Hitachi one, which we already had in another room. But my sister’s friend who had an appliance shop said that the Hitachi one was bad, and recommended that we get the Carrier instead (more expensive by a few thousand pesos).
SRP for the Hitachi is around 26k, for the Carrier, it’s around 30k. We got most of them on promo where they gave us free stand fans.
We wanted a window type aircon because it’s just easier – installation is faster since we already have the aircon hole (rectangle), and aircon cleaning is cheaper – just P400-500 for window type vs. P1000+ for split type.
CARRIER 1.0 HP Window Type Inverter Aircon
Anyway, we decided to try the Carrier upon his recommendation. Everything seemed okay. But that aircon was seldom used anymore after the first few months, then the ber months were cold enough not to use the aircon as much because that bedroom had good air ventilation. Haha, tipid mode pa din! 😀
Then last week, it started getting warmer, so the Carrier aircon was used. But it wasn’t getting cold at all. It was like it was stuck in FAN mode. After trying different modes on our end and the aircon was still not getting cold, I finally called Carrier for service.
Fortunately, we were still within the 1-year warranty so the service was free. Technicians came to our house, we explained the problem, and they knew what the problem was immediately.
Apparently it is a known issue – one of the sensors was triggered because of power surges. So all the technician did was reset the thing and that solved it. The aircon was putting out cold air again and the room was getting colder.
Of course, I asked him why this happened and how we can avoid such a thing in the future. Yeah, because if this happens again and we’re out of the warranty period, we’ll have to pay for the technician to come and reset the thing. Sayang naman kung ganun lang. According to the service form, he performed a “reset coil sensor” something something (couldn’t read the rest).
Also, we have 2 Hitachi inverter aircons in other bedrooms and we’ve never had a problem with them like this. J also has the same Hitachi inverter aircon. So 3 Hitachi inverter aircons bought 1-2 years ago and I’ve never heard of them having any problem as what this Carrier inverter aircon had.
Wala namang masabi si kuya except he told us to just unplug the aircon whenever it’s not in use nalang. Hahaha. So we’ll have to plug the aircon every night before turning it on, and then unplug it every morning after use. That’s the solution. LMAO. Hassle.
Well, at least the service was free this time, so I wasn’t pissed off that bad. Imagine if that was the problem and then I had to pay for them to fix what was essentially a product design flaw. We also have one free aircon cleaning pala, part of the package, that we should avail of before our warranty ends.
Also, the filter for this Carrier model was not as easy to remove and put back as other aircons.
HITACHI 1.0 HP Window Type Inverter Aircon
When we bought our first Hitachi aircon a few years ago, it was the cheapest and probably the only one available window type inverter aircon in the market (compact version). I really did not have high expectations. But my sister’s friend E recommended it because she had one. So we tried first with one aircon. It worked really well, even at 25-26 Celsius it was cool. This aircon runs almost 24/7 and the only problem is we have to have it cleaned more often because it gets dirty faster.
J’s old aircon broke so I recommended the Hitachi to him, too. Then a few months ago we bought another Hitachi again. So far so good, we haven’t had any problems. These aircons can get very cold! (a good thing)
We haven’t had any problems with these Hitachi aircons, and they are even used more than the Carrier one. No electrical surge issues. So many power interruptions have happened since we got them, no problem. We just clean the filters when we feel that they are dirty (every 1-2 weeks ideally but mostly just when we remember to) and then when we feel that the aircon is not getting as cold as it used to, we get it cleaned (every few months).
Update May 10,2018: Some of you requested for a fuller review of the Hitachi, so I made one: http://www.karenmnl.com/hitachi-window-type-inverter-aircon-review-compact/
Both these aircons work well at cooling, they both have remotes. The Hitachi remote works better if pointed at the aircon (we have the remotes velcro stuck to the wall near the door so they don’t get lost). I wish they had the remote wall mount thing that our old LG aircons had, so we didn’t have to ghetto-fix these remotes with velcro tape.
All of these newer aircons don’t have the wall mount. Update: the Carrier has a remote control holder. See update below.
However, the Hitachi Window Type Inverter Aircon will be the one we will be getting for the next bedroom to be upgraded to an inverter aircon because I feel like it is better designed for the Philippine setting. The Carrier,
a Filipino brand, a US-based brand locally manufactured by Concepcion Industries, which I expected to be more suited to our electrical surges, fails at that, as discussed above. If we ever encounter this problem again we would most likely be already out of warranty and have to pay for the service. The plug / unplug thing that we need to do every time we use it is such a hassle! Either that or we have to install some surge protector thing for it pa. Sigh. Also, the Hitachi aircon is easier to clean (filter).
Even with all 3 inverter aircons in use, our Meralco bill was even 1/3 lower than our previous Meralco bills! The change to using an inverter aircon really did reduce the electricity consumption BY A LOT. Of course, the initial amount spent to buy the inverter aircons will take several years before it’s recouped. Next projects: inverter refrigerators!
UPDATE: March 12, 2018
I was contacted by Carrier customer service when they heard about this problem. They were very helpful even though I told them that the aircon was already working fine. They replaced our aircon with another one of the same model. They insisted on checking the unit and even fixed the installation. The original guy we got to install the Carrier did a poor job, and while that did not really affect the aircon itself, there were small gaps between the aircon and the aircon “hole”. Our usual aircon guy was not available to install the Carrier when we bought it so we settled for another installer guy, who was apparently a newbie.
The Carrier service person who inspected the unit helped us fix the gaps. He really went above and beyond what I expected. He even checked the wiring and changed the aircon outlet to rule out any problems.
As for the remote control holder, it turns out that the Carrier does come with a remote control holder, and a drain pan. The original installer did not install them and we don’t know where he put it or if he took them. This was during a very messy, harassed time for our family last year when our dad underwent major surgery, so we really didn’t have the time or manpower to make “tutok” the installation. Carrier provided us with a remote control holder, drain pan, and even installed it for us.
I am very happy with the customer service that we received from Carrier for this issue. Like I said, they went the extra mile. While other companies might take my concern negatively and just ignore me, Carrier took it constructively and totally changed my view of them. They didn’t have to do any of this, but they did. The Carrier guy who I talked to said that they take customer service seriously and take care of their reputation for good service.
After this experience with Carrier customer service, I’m actually feeling confident about their aircon now. FYI, the technician who first checked our Carrier aircon was from an authorized service center. The guy I am dealing with now who did everything I told you about is from Carrier mismo, and he is very knowledgeable tech-wise, and had tools and engineering gadget things. I felt like he knew what he was doing talaga, and he was able to explain things to me clearly.
UPDATE: June 13, 2018
We experienced the same issue again – the Carrier aircon stayed in fan mode even after setting it to cool; the compressor was not engaging. Take note, this is the replacement unit already, and not the original aircon anymore.
A service tech came by to check on it and he said that we might be pressing the remote control buttons too soon (sunod sunod pinipindot) without waiting for the aircon to respond to the first remote control press. He replaced the thermostat or something, I didn’t really understand the whole thing because I wasn’t able to watch him since he arrived at a bad time.
Anyway, the Carrier aircon seems to be fixed now, but I still want to know what the problem was. I am not really buying the “pressing the remote too fast” explanation that he is blaming on us.
UPDATE: October 20, 2018
Our Carrier aircon had the same problem again. I spoke with the service manager who came by the house to check on the unit. So it turns out that Carrier has been really “strict” when it comes to electricity fluctuations and set their threshold with only a small tolerance for deviation. Unfortunately, Meralco being the way it is, our electricity has been fluctuating and we experienced some very quick brownouts that lasted for a few seconds to a few minutes. The Carrier has a “protection” thing where if the electricity fluctuates beyond the acceptable range for 3x in one hour, the aircon will not let the compressor engage as a protective measure. So apparently, this is what has been causing all this “not cooling” problems we’ve been experiencing.
There is a very easy fix for this. You just press a few buttons on the remote, there is a specific button combination to do. I was asking but he wouldn’t really explain what it does exactly. He says it “updates” the aircon but I don’t understand how, by OTA? by Bluetooth? How can the remote get the new software to update the aircon? He just said that if you experience the “compressor not engaging” problem, just call their customer service / technical support, and they should be able to guide you on what buttons to press. Or, the technician can do a home service and do the button thing for you. Also, he said that they when you have your aircons cleaned, they have already instructed their service techs to update the aircon (by doing the button thing).
After that, if you ever encounter the same thing again, all you have to do is to unplug / plug your aircon. The unplug / plug should reset the aircon protection thing that was triggered when the aircon registered 3x beyond the norm fluctuations in one hour.
