The main reason for the slow heating of air conditioners There are several reasons for the slow heating of air conditioners: The dirt of the transpiration device and the condenser is too thick, which will cause air flow blockage, affect the heat declaration, and make the air conditioning heating a big discount. The filter is not cleaned for a long time<img src="{{media url="wysiwyg/The_main_reason_for_the_slow_heating_of_air_conditioners.jpg"}}" alt="" />
