Do You Need to Wait for the Engine to Warm Up Before Turning on the AC in Summer?

[SanAndrew]

In summer, you don't need to wait for the engine to warm up before turning on the AC, but you do need to wait in winter when using the heater. Here are some precautions for using the car air conditioning system: 1. Select the appropriate fan speed: During normal operation, to prevent excessive frosting on the evaporator which could affect the AC system's performance, avoid setting the fan speed and temperature control at the lowest settings for extended periods. When driving below 25km/h, set the fan speed to low to prevent insufficient power generation and cooling capacity. 2. Duration of AC usage: If the cabin temperature has reached a comfortable level, you can turn off the AC or switch it on intermittently. Prolonged use of the AC will increase the condenser pressure excessively, causing wear to the refrigeration system, so avoid using the AC continuously for too long each time.
