If a new car's air conditioning stops cooling after more than two years, it is important to regularly clean and maintain the air conditioning evaporator and replace the air conditioning filter in a timely manner. The functions of car air conditioning are: 1. To achieve a cooling effect through the continuous cycle of refrigerant; 2. To remove dust, odors, smoke, and toxic gases from the air inside the car, making the interior air fresher, and to humidify the air inside the car, increasing the relative humidity. The maintenance methods for car air conditioning are: 1. Do not set the temperature too low; 2. Control the direction of the air vents; 3. Avoid prolonged use; 4. Occasionally use high fan speed; 5. Turn off the air conditioning when driving at low speeds.

My car's air conditioning stopped cooling after just two years of use. Last summer during extreme heat, it blew warm air like a heater. The mechanic at the repair shop said refrigerant leakage is a common issue, possibly due to small cracks in the pipes or aging seals. After refilling with new refrigerant, it became much cooler. They also found the air filter completely clogged with dust - cleaning it made a noticeable improvement. New car AC systems typically last 3-4 years without issues, but neglecting maintenance can cause early failure. They recommended annual checks for both the filter and refrigerant pressure to prevent compressor overload damage. Avoid frequently and abruptly turning the AC on/off while driving - gentle operation extends lifespan. Early detection saves both money and hassle.

When the car's air conditioning becomes less cool after a few years of use, it is usually caused by insufficient refrigerant or a system leak. The compressor and condenser will gradually wear out with frequent use. I make it a habit to have a technician test the refrigeration system pressure every two years to ensure proper circulation; at the same time, I clean the evaporator to prevent clogging. Over-reliance on maximum fan speed can easily accelerate component aging, leading to reduced cooling. Simple maintenance like replacing the filter can be done by yourself at a low cost, preventing major issues. Ignoring these small maintenance tasks for four or five years can lead to expensive repairs later. Taking early action ensures higher efficiency and longer durability of the air conditioning system.

If the air conditioning in a new car becomes less cool after five years, it is mostly due to a lack of refrigerant or clogged components. Reluctance to pay for maintenance can lead to compressor failure and costly replacement. It is recommended to spend a little money each year to check the refrigerant pressure and replenish it in time to avoid complete system failure. Regularly changing the filter and keeping the air intake unobstructed can save on repair costs. Poor air conditioning efficiency also affects fuel consumption, so early maintenance saves money and ensures peace of mind. Remember to schedule simple and hassle-free inspections after three years.
