The worst thing young adults can do is go to graduate school because they aren't sure what else to do or they can't find jobs. Grad school, after all, is often an extremely long commitment. A Ph.D., for example, can take six years.
The average lifespan for an air conditioner is 10 to 15 years. Some air conditioners last up to 20 years. As interesting as these data points may be, they don't tell you the whole story. The issue is that a variety of factors affect the lifespan of an air conditioner.
A traditional air-conditioner uses a thermo-stat for feedback and works in binary mode. Lets try and understand this by an example. Suppose you set the temperature of your air-conditioner to 23. The compressor runs on full power till the thermostat gives it a feedback . It shuts down when the required temperature is reached. The high starting current and regular start/stop cycle increase wear and tear in the mechanical parts and hence our air-conditioners need servicing as well as consume huge amounts of electricity/money. Contrary to this , in an inverter air -conditioner the compressor is always on .
