How many years does a new car's air conditioning stop cooling?
2 Answers
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.
