Let’s dwell on the first two brands – Mitsubishi, and Daikin. These are rightfully considered the most expensive and most innovative brands in the world of air conditioning. They set the fashion and standards in the world of air conditioning. Servicing air conditioners of these brands requires highly qualified technicians, because every mistake here costs quite a lot of money, especially if we are talking about servicing industrial air conditioners.

The main difference between these models is reliability. Reliability is achieved in two well-known ways:

Quality of materials used.

(this is a separate topic, the quality of the materials is simply impeccable, starting from the plastic from which the case is made, and ending with the air conditioner compressor itself. The details are thought out and well-fitted. In such air conditioners as Daikin and Mitsubishi, you will not hear creaks, unnecessary noises, the smell of cheap plastic, the vibration of the outdoor unit, etc. Japanese manufacturers have saved us from these troubles. These brands are sometimes jokingly called eternal air conditioners. We understand that nothing is eternal, but these air conditioners are long-livers. If you regularly carry out maintenance of air conditioners, they easily “live” for twenty years)

Protection systems.

(by protection systems we mean protection against voltage surges, protection against overheating and overcooling, protection by freon level, and much more. When diagnostics and cleaning of air conditioners are carried out, technicians most often try to bypass these protection systems. Thus, there is a high probability of failure of expensive equipment.

The simplest example of filling by pressure – many Japanese air conditioners have electronic regulation of freon pressure in the system. When cleaning air conditioners, the bad master thinks “The pressure is a bit low, let me fill it up.” He does not even suspect that the air conditioner itself has set such pressure. 

Then he starts filling the air conditioner, and the air conditioner understands that there is more freon than necessary, but it carries out automatic pressure regulation and the pressure does not increase. In turn, the stubborn one does not give in and continues to fill the freon into the air conditioner until we get a hydraulic shock of the compressor. Then there is an expensive repair) Unfortunately, foolproof protection does not always work and we get such very unpleasant moments.

In conclusion 

I would like to say that the maintenance of air conditioners by Daikin, Mitsubishi, Panasonic, Toshiba, Fujitsu, Hitachi, and other Japanese brands should be carried out exclusively by people with good work qualifications. The company “DR HVAC” employs such professionals who are ready to come to your aid at any time. Call and order air conditioner maintenance, and you will see that after us the air conditioner will work like new.
