How to Determine When a Car's Air Conditioning Needs Cleaning: 1. When the air conditioning is first turned on, before the air fully cools or heats, a musty or dusty odor is noticeable. 2. When cooling or heating, the air blown from the vents is not fresh and may have a sour or other unusual smell. 3. Reduced cooling efficiency and increased fuel consumption. This is due to the evaporator coil being clogged with dirt from long-term lack of cleaning, affecting heat dissipation. Extended Content: The main reasons for cleaning a car's air conditioning are: After prolonged use, about 80% of tiny dust particles and bacteria in the air pass through the filter and enter the air conditioning system, bonding with condensed water and clogging the evaporator. If these dust and dirt are not cleaned in time, various problems can arise. This not only affects the cooling and heat dissipation of the air conditioning but can also pose health risks.
