What to do if the car air conditioner is not cooling well?

The belt of the air conditioning compressor is too loose. Tighten the belt of the air conditioning compressor. If the filter is too dirty, it will not only introduce more impurities into the air inside the car, but the dirt will also block the air conditioning filter, so the filter needs to be cleaned. If various impurities tightly cover the condenser, the condenser will not be able to dissipate heat normally, so it needs to be cleaned.
A while ago, my car's air conditioning wasn't cooling enough either. Later, I found out it was mainly because the cabin air filter was too dirty and blocked the air duct. Cleaning it myself actually helped. You can start by checking the filter's location, usually under the front windshield. Take it out, clean it with a vacuum or wash it with water, let it dry, and then put it back. If that doesn't work, low refrigerant could be a factor, but I suggest not adding refrigerant yourself—high pressure can easily cause problems. It's best to go to an auto repair shop to check for leaks or compressor damage. For regular maintenance, remember to change the filter once a year to prevent dust buildup. Before using the car in summer, it's good to turn on the air conditioning for a few minutes to help extend its lifespan. If you encounter any issues, don't delay—fixing them promptly can save you a lot of trouble.
