The invention discloses a non-industrial air conditioner flexible load control method and system. The method is characterized in that three user-side operation strategies of a maximum load strategy, an optimal comfort strategy and a comfort equilibrium strategy are make according to a non-industrial air conditioner control participation way and characteristics of a typical building, so that the user-side comfort is balanced and load capacity is reduced to the greatest extent. Meanwhile, a non-industrial air conditioner load control master station system is established, and a communication network between the master station system and a user side is established, so that a demand response terminal and the load control master station realize data interaction, and therefore, the non-industrialair conditioner flexible load control purpose is achieved, area electricity utilization peak is effectively reduced, and safety and economical efficiency of area power grid integral operation are improved.
