Hello friends! I want to share some information about drawbacks. Which its circuit more complex. Conversation energy is losses more these Acs often come with R410A refrigerant gas while most technicians still only have an R-22 Refrigerant gas. Worst condition is its cooling which is very far from satisfaction actually when I listened about TCL then I thought may be its better or equal compare then others brand but I am very depressed after purchasing and used. So now finally I sold it on half price due to least service and maintenance. So plzz be aware from this type of your bad output decisions.
