What are the reasons for poor air conditioning cooling effect in the xrv?

The following are the specific reasons for poor air conditioning cooling effect in the Honda xrv: 1. Insufficient or low refrigerant: This may be caused by a small refrigerant leak. It can be observed from the sight glass on the dryer tank. During normal operation of the air conditioning, if there are continuous bubbles in the sight glass, it indicates insufficient refrigerant. If obvious bubble flipping occurs, it indicates a severe shortage of refrigerant. In this case, simply adding refrigerant will suffice. 2. Loose drive belt of the car air conditioning compressor: If the drive belt is loose, the compressor will slip during operation, leading to reduced transmission efficiency and a decrease in compressor speed. This results in reduced delivery of compressed refrigerant, causing the car air conditioning to not cool properly. If the compressor drive belt is too loose, it should be tightened. If it cannot be turned by hand, it indicates the drive belt is too tight and should be slightly loosened. If tightening is ineffective, or if the drive belt has cracks, aging, or other damage, it should be replaced with a new one.
My old XRV has been running for three years, and last year the air conditioning started cooling slowly with no cold air coming from the vents. I figured it might be one of these common issues: the AC filter was too dirty and blocking airflow—I took it apart and found it full of dust; refrigerant leakage causing insufficient pressure to drive the system; the condenser fins were clogged with dust like a blanket, so a cold water rinse would help; the compressor not working due to a loose belt or stuck solenoid valve; or the temperature sensor acting up and giving false readings. That time, I replaced the filter and cleaned the condenser, which solved about 80% of the problem, saving me 500 bucks at the repair shop. On hot days, I start by turning on the external circulation to vent the heat before switching to internal circulation—the AC cools faster and saves fuel.
