What Causes the Unpleasant Odor in Chery Ant's Heating System?

[GraceLynn]

Chery Ant's heating system unpleasant odor reasons are as follows: Evaporator (also known as the evaporator box) issue: The car's heating primarily comes from the heat of the radiator, which is located inside the evaporator. The heating system utilizes the engine's cooling process to blow heat into the cabin via a blower. Over time, a small amount of moisture and dust may accumulate on the evaporator, leading to mold growth and consequently producing an unpleasant odor. Air conditioning duct odor: The air conditioning ducts can develop an odor due to dampness and mold. It is recommended to turn off the AC switch 2 minutes before parking and switch to external air circulation to continue blowing until the car is parked. This practice helps dry out the moisture in the ducts and prevents mold growth. Air filter odor: The air filter has a usage cycle and should generally be replaced every two years. Over time, it can also develop mold and produce an unpleasant odor. Additionally, bacteria can accumulate inside, which is harmful to human health.

I've driven quite a few cars myself, and it's quite common for the Chery Ant's heater to develop unpleasant odors. The main reason is the growth of mold or bacteria inside the evaporator due to moisture, especially after seasons with heavy rain or frequent use of the air conditioning. The odors are usually musty or dusty, stemming from an aging or clogged cabin air filter, which results in less fresh air being blown out by the heater. Leaving the heater unused for long periods or parking the car for extended durations can also lead to moisture buildup and rampant mold growth. The solution isn't difficult—regularly replacing the filter is key, at least once a year, and using an automotive air conditioning cleaner to spray the air intake while running the fan to clear out dirt. Developing a habit of running the heater for half an hour during non-rainy seasons can help sterilize and prevent issues beforehand. If the problem becomes severe, a professional deep cleaning at a repair shop may be necessary. Failing to address it promptly can degrade the air quality inside the car and even trigger coughing or allergy symptoms.

I'm the kind of person who loves figuring out car issues. The foul smell in Chery Ant's heater is too simple to fix. The odor is 99% caused by a dirty evaporator or an old air filter. If you often drive with windows closed, the humidity builds up and mold starts growing. When I dealt with my own car, I bought a cheap car cleaning spray for about ten bucks, sprayed it into the AC intake, and turned the fan to max to blow out debris—easy fix. Remember to replace the filter first, or the cleaning is wasted. Electric car heating systems tend to accumulate moisture, so I suggest blasting hot air at high temp for about ten minutes every few months to disinfect. DIY saves time and money, but if the smell turns chemical, it means wiring issues—better get it professionally cleaned. Don’t delay too long; it affects driving mood.

I've encountered the issue of foul-smelling warm air in the Chery Ant, which is mostly caused by moldy evaporators or contaminated filters. Humid weather or improper use of the air conditioning can lead to bacterial growth inside the system, resulting in smelly air being blown out. The solution is to clean the evaporator and replace the filter, with preventive checks during each maintenance session. Ignoring it may allow bacteria to spread and harm the respiratory system. Simple maintenance can prevent most problems.

As a health-conscious individual, don't overlook the musty odor in Chery Ant's heating system. That mildew smell comes from bacterial growth in the AC system, which may cause respiratory discomfort or allergies when inhaled, especially harmful to children. The causes often lie in expired filters or damp evaporators. Regular sterilization, cleaning, and replacing with high-efficiency filters are essential. We recommend visiting professional shops for comprehensive treatment to ensure clean, fresh air. Don't delay for cost savings - health impacts are irreversible.
