5 Harms of Neglecting Evaporator Coil Cleaning

14.08.2025

Bạn có bao giờ cảm thấy khó chịu vì chiếc điều hòa xe bỗng dưng bốc mùi hôi hoặc làm mát kém đi? Bạn đã thử đủ mọi cách nhưng vẫn không hiệu quả?

1. Weak Air Conditioning, High Fuel Consumption

An evaporator coil that is fully covered in dirt will obstruct the airflow, forcing the air conditioning system to operate at a higher capacity to cool. This not only reduces cooling efficiency but also leads to unnecessary fuel wastage. When the compressor has to overwork, the car's engine also bears added pressure, causing fuel consumption to spike. Periodically cleaning the evaporator coil is a simple and effective way to save fuel for your car.

2. Risk of Contracting Respiratory Diseases

The air inside the car can be more polluted than the air outside if the evaporator coil is dirty. The damp and dark environment inside the evaporator coil is an ideal condition for bacteria, mold, and pathogens to grow.

When the system operates, they are blown directly into the cabin, causing health problems such as allergies, rhinitis, pharyngitis, and other respiratory diseases. This harm is especially serious for children and those with compromised immune systems.

3. Air Conditioning System Failure

Long-term dirt accumulation not only reduces performance but is also the main cause of damage to important components. Dirt can clog ducts, cause refrigerant leaks, or even damage the air conditioning compressor—a part with a very high replacement cost.

Periodic cleaning is the best way to protect the entire air conditioning system from unnecessary damage, helping the car operate smoothly.

4. Expensive Repair Costs

Compared to the cost of cleaning the air conditioner evaporator coil, the repair cost when the system breaks down is a much larger figure. The average cleaning cost is typically around one million VND, while replacing or repairing components like the compressor can cost 5-10 million VND or even higher.

Proactive maintenance is a smart way to save money, avoiding unexpected and sudden expenses.

5. Unpleasant Odors, Affecting the Driving Experience

A dirty evaporator coil will create unpleasant odors, ranging from a musty, sour smell to an indescribable stench. This smell not only affects the comfort of the occupants but can also cause distraction while driving.

A fresh and pleasant cabin environment will help you feel more relaxed and safer on every journey.
