maxj23 0 Report post Posted July 17, 2015 Hi all just wanted to ask, i have a system 4 aircon and btu capacity for outdoor unit is 28k btu. Indoor unit for living rm is 18k and 9k x3 for each bedroom. If i use 2 bedrooms 9k each + living rm 18k total use is 36k btu, will it cause damage or overload to the outdoor unit?
