The present invention provides an air conditioning surge testing method and system and belongs to the air conditioner testing technical field. The air conditioning surge testing method is applied to the air conditioning surge testing system. The system includes a test host, a front-end collector and a sensing unit, wherein the test host and the sensing unit are electrically connected with the front-end collector. The method includes the following steps that: the front-end collector collects the real-time characteristic information of the air outlet of the indoor unit of an air conditioner to be tested through the sensing unit, wherein the real-time characteristic information contains at least one item selected from air speed information and sound pressure information; and the front-end collector sends the collected real-time characteristic information to the test host; and the test host determines whether surge noises are generated according to the real-time characteristic information.According to the air conditioning surge testing method and system of the invention, a test result which is obtained through analysis based on objective real-time characteristic information change ismore objective; an entire testing process is automatically realized; long-term and sustainable testing can be performed; the efficiency of the testing can be the improved; and the labor costs of the testing can be reduced.
