The Mitsubishi Heavy Industries MSY-KJN are good entry-level home air conditioning units that are compact and efficient. This review is being written by Steve who had worked previously on quite a few different split system installations but would not consider himself an expert on this product.
Heater/Cooler Review: The MSY-KJN is a single zone split system, meaning that it can top up or cool down your room in order to make the temperature more comfortable. As it is only a single zone, this also means that you cannot get heating and cooling at the same time. This shouldn’t be an issue for most people, but if you are looking for both heating and cooling at the same time then you may need to look at some other options.
The first thing that Steve noticed about this unit, and which was repeated by many users, is how easy it is to install and set up. It can be done on your own with little trouble. This is a huge bonus as most people do not like paying large fees to have a technician come and do the job for them.
The next thing he noticed is how quiet it was compared to his old unit. As this was an upgrade, it meant that he did not really notice the difference in noise over the course of the day. However, when his wife came home she commented on how much quieter it was and felt that the house was cooler. To be sure of this, he walked up to it and could barely hear a whisper. The amount of noise that a split system makes is a very important factor for many people as it can drive them batty if they have to listen to it all day long.
In terms of cooling power, Steve found that it cooled the house down quickly and efficiently. It was able to cool down a room by 5 degrees in under 20 minutes which is nice, but not something he would brag about. He did notice however that once the desired temperature had been reached if left on the eco mode the unit will run intermittently for another 30 minutes or so before finally turning off. He found that this was an effective way to keep the room at a constant temperature and that it did not run all day long which would be very inefficient.
The Mitsubishi Heavy Industries MSY-KJN is high quality and reliable unit with great features. The fan speed modes are pre-programmed but he did find that he was able to adjust it slightly. Because the unit is only a single zone, you will either need to buy another MSY-KJN if you want heating and cooling or look at some of the other options on the market. Steve actually had this installed in his home and found that it runs very quietly, so he doesn’t have to worry about ticking his wife off. He did find that the timer was annoying and he didn’t see why it couldn’t be turned off, but that was probably just him. All in all, this is a great unit and if you are looking for something quiet with low power consumption then this might be the one for you.
