A system and a method for controlling air massage pressure using variable frequency are disclosed. The system and method allow a user of a massage chair to adjust the air massage pressure to any desired level electronically. Air compressor power is controlled by varying the frequency of the power supply. The air pressure is monitored by a pressure sensor that forms a closed loop feedback control. This design allows for fast response and smooth pressure control. In an embodiment of an aspect of the present invention, a system for controlling air massage pressure using variable frequency includes at least one air compressor, a master control board that includes or is equivalent to a variable frequency controller and a controller interface associated with the variable frequency controller, and a pressure sensor. The system may also include a temperature sensor, a current sensor, a power source, and/or a remote control.
