What Causes the Foul Smell in Surui's Air Conditioning?
3 Answers
Surui's air conditioning emits a foul smell due to the accumulation of dust and dirt in the system over time, which leads to mold growth and odor. The Surui is a compact 4-door, 5-seater sedan with body dimensions of 4680mm in length, 1765mm in width, and 1490mm in height, with a wheelbase of 2660mm. It is equipped with a 1.5L naturally aspirated engine that delivers a maximum power of 80 kW at 5800 rpm, paired with a 5-speed manual transmission. The vehicle features front-wheel drive, with a MacPherson strut independent suspension at the front and a torsion beam non-independent suspension at the rear.
I recently encountered the smelly air conditioning issue with my Surui too, it's really annoying. The main problem is the accumulation of water and dirt in the evaporator box of the AC system. If you don't use the external circulation for a long time, mold starts to grow, especially after rain when the humidity is high, the smell becomes more noticeable. Additionally, if the AC filter is too old and hasn't been replaced, it's full of dust and bacteria, and the smell comes out as soon as the air blows. Last time I took my friend's car to the repair shop, the mechanic said the drain hole was blocked, preventing water from draining, and it got much better after an evaporator box cleaning. Now I regularly open the windows for ventilation for a few minutes, check the filter every month, and buy inexpensive activated carbon filters to replace them—it's not expensive. Avoid using internal circulation for too long, and after starting the AC on hot days, turn on the external circulation for a few seconds before closing the windows.
The unpleasant odor in the Surui's air conditioning system is commonly encountered during humid seasons. This occurs because residual moisture and dust inside the AC system, particularly on the evaporator surface, foster the growth of bacteria and mold, resulting in an unpleasant smell when the air blows. I recommend scheduling a thorough professional AC cleaning at an auto repair shop. They use specialized cleaning agents sprayed into the system to effectively eliminate bacteria and odors. Additionally, remember to inspect and replace the cabin air filter—a task you can easily do yourself by purchasing the correct model online and following the installation instructions, which is quite affordable. For daily use, turn off the AC a few minutes before parking and run only the fan to dry out the system. Adopting this habit will generally resolve odor issues.
