Many car owners lack knowledge on using and maintaining their car’s AC, leading to frequent malfunctions and costly repairs. Here are DIY solutions to common AC issues, saving time and money.

The car’s air conditioning is ineffective and the airflow is insufficient.

The possible reason for the air conditioner not providing enough cooling and the weak airflow, despite being set to the highest setting, could be attributed to:

  • The evaporator is not performing optimally. To fix it, you need to bring your car to a repair garage for expert diagnosis and treatment.
  • The amount of air blowing through the cooling system is poor, not enough, and cannot keep up with the increase in temperature of the air in the car. To fix this, check the air conditioner filter to see if there are foreign objects in the ventilation duct or filter, and clean the air conditioning system’s air filter.

Check the air conditioner filter

The car’s air conditioner initially provides cool air, but later stops cooling.

It is a common occurrence in cars that have been in use for a long time. The reason why the air conditioner in a car initially cools but later loses its coolness might be attributed to excessive dust accumulation on the air conditioner condenser or a malfunctioning cooling fan.

If you are facing an issue with your car air conditioning system not cooling properly, you can address it by utilizing car interior cleaning solutions to clean the air conditioner condenser. Additionally, it is recommended to inspect the cooling fan to determine if there is any malfunction or issue contributing to the problem.

Please follow Quantrimang’s recommendations and consider using the following cleaning spray products to address the issue of inconsistent cooling in your car’s air conditioning:

1. AC Safe Foaming Coil Cleaner: This product effectively cleans and removes dirt, dust, and debris from the cooling coils of your car’s air conditioning system. It helps improve air flow and restore proper cooling performance.

2. Nu-Calgon Evap Foam No Rinse Evaporator Coil Cleaner: Ideal for cleaning evaporator coils, this foam-based cleaner eliminates dirt, mold, and mildew that can obstruct airflow and cause cooling issues. It doesn’t require rinsing, making it easy to use.

3. CRC Industries Coil Cleaner: This powerful foaming cleaner is designed to remove dirt, grease, and grime that accumulate on condenser coils. By using this product, you can enhance the heat transfer capabilities of your car’s air conditioning system, ensuring consistent cooling.

4. Kool-it Evaporator and Heater Foam Cleaner: Formulated specifically for car air conditioning systems, this foam cleaner penetrates deep into the evaporator and heater cores to remove build-up and debris. It helps improve cooling efficiency and eliminate unpleasant odors.

Remember to carefully follow the instructions provided on the product labels to ensure safe and effective usage.

The car’s air has an unpleasant smell.

The reason behind the car’s air conditioning system emitting a foul odor is primarily due to the excessive accumulation of dirt in the filter system. Additionally, it is possible for insects or mice to enter the system and perish inside, further contributing to the unpleasant smell.

In order to resolve the issue, you should either clean or replace the air conditioner filter. It is recommended to replace the car’s air conditioning filter after every 20,000km or after using it for 2 years.

Here are some tips on how to utilize the “Rodent Repellant Coating Spray” effectively to eliminate mice from both the interior and engine compartment of your car:

1. Begin by thoroughly cleaning your car’s interior, removing any food crumbs or potential nesting materials that may attract mice.

2. Shake the “Rodent Repellant Coating Spray” bottle well, ensuring that the ingredients are properly mixed.

3. Spray a generous amount of the coating on all areas of the car’s interior that are prone to mice infestation. Focus on areas such as the floor mats, seat cushions, and storage compartments.

4. Pay careful attention to areas where mice commonly nest, such as the glove compartment, trunk, and under the seats. Apply an extra coat of the repellent in these spots to create a strong barrier against mice.

5. For the engine compartment, spray the “Rodent Repellant Coating Spray” on all exposed wires, hoses, and any other vulnerable areas. It is important to cover all potential entry points for mice.

6. Reapply the coating every few weeks or after heavy rain to maintain its effectiveness and ensure ongoing mouse deterrence.

7. As an additional precaution, consider using traditional mouse traps or placing rodent repellent sachets inside the car to reinforce the protection provided by the spray.

Remember to closely follow the instructions provided by the manufacturer to ensure safe and proper application of the “Rodent Repellant Coating Spray”.

Ice is trapped in the AC system.

Ice can form on the air conditioning evaporator when there is not enough refrigerant gas. This causes a significant drop in pressure in the tanks, which in turn lowers the boiling temperature of the gas. As a result, the refrigerant gas evaporates at lower temperatures, making the coil much colder than its designated condensing temperature. When air passes through the system, the water vapor present can freeze on the tube surface and any gaps that are present.

To address any issues with the air conditioning system, simply refill it with the appropriate type of high-quality refrigerant.

The vehicle’s AC emits a gasoline odor and is lacking sufficient cooling capabilities.

A car smells like gas and is not cold because there is a leak in the cooling system.

The air conditioning system operates as a closed cycle, which means it rarely experiences leaks. However, if you do come across this issue, it is crucial for the car owner to not attempt to fix it themselves. Instead, they should promptly take the car to an authorized service station or a trusted service workshop for a thorough inspection and proper resolution.
