The Cost Of Car Air Conditioner Cleaning Is Affected By Many Factors. How Much Does A Professional Foam Cleaning Agent Cost?
A thorough "respiratory system" cleaning: why you need to deep clean your car air conditioner
Just this past summer, when I went to a client's home to perform a deep cleaning of the whole house, he told me a problem. Every time he turned on the air conditioner in the car, there would always be a sour and musty smell that was worse than the smell of exhaust outside the car. As a senior home economist, I understand that this is not just a matter of "taste". The air conditioning system of a car, especially the evaporator box, is simply a "super petri dish" for mold and bacteria in a closed environment with alternating hot and cold temperatures all year round. The simple "no disassembly and washing" spray can only cover the smell for a short time, but cannot solve the fundamental problem at all. Just today, I will tell you how to effectively perform in-depth maintenance of car air conditioners from a professional deep cleaning perspective.
Tool selection: Professional equipment is the foundation for deep cleaning
Professional deep cleaning of car air conditioners is different from the "one bottle of foam" method at roadside auto repair shops. It is like a precise minimally invasive surgery. What we need to prepare is not just cleaning agents, but a complete set of visualization equipment. The main core tools covered are as follows: There is a high-definition endoscope, which is used to observe the pollution conditions inside the evaporation box; there is also a special cleaning spray gun, which is bendable and capable of multiple angles; there is also a high-power suction machine, which is used to suck away dirty foam; it also includes special air-conditioning evaporation box cleaning agents and bacteriostatic agents. The choice of cleaning agent is very important. Professional products with a neutral pH value must be used to prevent corrosion of the hydrophilic coating on the surface of the evaporator. This cannot be replaced by household detergent. In addition, a complete set of protective equipment, such as goggles and gloves, is also necessary to prevent eyes from being hurt by splashing objects during the cleaning process.
Operational process: three rigorous steps from "diagnosis" to "cure"
The initial stage is disassembly and diagnosis, which is different from simply taking out the air-conditioning filter. During deep cleaning, the blower or fan resistor must be removed, and interior parts such as the glove box must be appropriately adjusted according to the car model to provide the endoscope and spray gun camp with After creating an operating channel, I will use the endoscope to show the client the surface condition of the evaporator in real time. The thick layer of sticky dust and mold spots are direct evidence of odors and allergens. The next step is to carry out precise cleaning and flushing. Use a special spray gun to evenly and comprehensively spray the foam cleaning agent on each fin of the evaporation box. Use the expansion force of the foam to wrap and peel off the contaminants. After leaving it for a few minutes, use high-pressure airflow or clean water with a suction machine to rinse repeatedly to completely discharge the dissolved dirt. The third step is disinfection and restoration. After cleaning, spray a long-lasting antibacterial agent, and be sure to replace the air conditioning filter with a new one before installation and restoration. Finally, start the vehicle, turn on the air-conditioning refrigeration function, adjust the air volume to the maximum, and blow away the remaining moisture in the pipes. The entire process is considered a closed loop.
Detail processing: "millimeter level" cleaning of evaporation boxes and pipes
The difficulty of deep cleaning lies in the "invisible part". The structure of the evaporator box is like a dense cooling fin, with a depth of only a few millimeters. It is impossible to reach with ordinary tools. When operating, I have to control the angle and strength of the spray gun to ensure that the cleaning agent can penetrate into the root of each fin. , but do not use excessive force to avoid damaging the fragile aluminum fins, and the waste liquid after cleaning must be extracted promptly and completely. If it is allowed to flow out naturally through the drain pipe, it may leave stains on the chassis components that are difficult to remove, or even block the drain pipe, causing water to accumulate in the car. In addition, cleaning the inside of the air duct is also important. I will use a slightly damp, lint-free professional rag and use a long-handled tool to wipe the leaves inside the air outlet. The dust here is a secondary source of pollution.
Guide to avoid pitfalls: Don’t be tempted by “no disassembly and washing” and low prices
In an auto repair shop, you may have seen what is called "visual cleaning", but the fee is only around 100 yuan. There is a huge trap here: a large number of so-called visualization modes only use an endoscope to let you take a look, and then spray some foam at will, without performing suction and water flushing operations at all. As a result, a large amount of dirty foam is left in the evaporation box. After waiting to be air-dried, it will cause the drainage holes to be blocked, and breed odors that are more difficult to dissipate and remove. For true deep cleaning, since it involves a large number of parts that need to be disassembled, takes a long time, and the equipment used is expensive (such as a suction machine), the labor cost itself is very high. According to the market situation we talked about at the beginning, the cost of "deep cleaning" that can access the evaporator box and condenser, combined with labor and materials, is generally 300 to 500 yuan or even higher. If a store gives an all-inclusive price of less than 200 yuan, it can basically be judged as a "superficial form." In addition, never replace the air conditioning filter element after cleaning because you want to save money. That is equivalent to adding a door to the garbage dump in the cleaned room.
Comparison of effects: from "Don't dare to turn on the air conditioner" to "Forest Oxygen Bar"
The effects it exhibits are immediate. Before the cleaning operation, the air in the car feels "turbid", and it is also mixed with the pungent fragrance left behind after being masked by chemical cleaners. After the cleaning is completed, when the customer sits in the cab again, the most intuitive feeling is the "transparency" of the air. The musty smell that would make people feel sick after smelling it has completely disappeared. It was replaced by the fresh smell that the air should have. You can even vaguely smell the aroma of fresh grass and trees coming from outside the car. Talking about health from another perspective, completely eliminating the huge group of mold called the evaporator box can greatly reduce the risk of respiratory discomfort in the car for passengers and drivers, especially children and people with allergies. The cooling effect of the air conditioner is usually improved obviously with the naked eye. This is because the "mud quilt" covering the radiator is removed, and the heat exchange efficiency naturally returns to its previous state.
Deep cleaning of car air conditioners is not a consumption behavior, but a necessary investment for the respiratory health of your family. Prices on the market vary from 100 yuan to 800 yuan. I hope this guide can help you see through the superficial phenomena to see the inner essence, avoid the so-called "no disassembly and washing" trap, and choose professional services that can truly solve the real problems, so that every time you travel, you can be accompanied by fresh and clean air.
