Should You Wait for the Engine to Warm Up Before Turning on the Air Conditioning?

[MacManuel]

Turning on the heating requires waiting for the engine to warm up to be effective, while turning on the cooling does not require waiting for the engine to warm up. Select the appropriate air conditioning fan speed setting: During normal vehicle operation, to prevent excessive frosting of the evaporator and to ensure the proper functioning of the air conditioning system, the air conditioning's fan speed and temperature control should not be set at the lowest settings for extended periods. When the vehicle speed is below 25 km/h, the fan speed switch should be set to the low-speed setting to avoid insufficient power generation and inadequate cooling. Duration of single air conditioning use: If the interior temperature has reached a comfortable level, the air conditioning can be turned off or turned on again after a while. Prolonged use of the air conditioning can cause excessive pressure on the condenser, leading to wear and tear on the cooling system. Therefore, the duration of each air conditioning use should not be too long.
