To a domestic brand to make a comparison of the two products, two different types of air conditioning, energy efficiency ratio were 3.42 and 2.92, respectively, the input power is 760 watts and 890 watts, the price difference is about 500 yuan .

And businesses install their own ranks. Outsourcing refers to the so-called air-conditioning installation work to a number of "guerrilla", compared to some merchants introduced stringent installation specifications, with a professional installation team.
Consumers to buy air conditioning before, pay attention to know whether there is a strict business installation specification, installation personnel are sufficient, as far as possible to reputable businesses in order to avoid disputes.
