Judging air conditioning lack of fluoride tips

As the peak season for air conditioning approaches, more and more people are starting to notice some maintenance issues with their units. One of the most common concerns is whether the system needs a refrigerant (fluoride) recharge. But how can you tell if your AC is low on refrigerant or if something else is causing the problem? Let’s go through some simple methods to help you identify if your air conditioner needs a fluoride top-up. A properly installed air conditioner should not require refrigerant for at least two to three years. If it starts leaking within just a few days, that’s a red flag. However, if your AC isn’t cooling, it doesn’t necessarily mean it’s low on refrigerant. There could be other issues at play. First test: Turn on your AC and let it run for about 30 minutes. Check if it reaches the set temperature. If the unit runs constantly without reaching the desired temperature, it might be a sign of low refrigerant. Second test: Use a thermometer to measure the temperature difference between the air coming out of the indoor unit and the air entering it. A healthy AC should have a difference of around 15 degrees. If the difference is less than 10 degrees, it could indicate a refrigerant shortage. Third check: After running the AC for 15 minutes, open the indoor unit panel. You should see condensation evenly covering the evaporator coil. If parts are dry or frosted, that’s a sign of an issue. Fourth test: If the outdoor unit is accessible, touch its two valves after running for 15 minutes. There should be a noticeable temperature difference. If the small tube is frosted, that may point to low refrigerant. If the large tube is frosted, it could mean poor system circulation. Fifth inspection: Use a pressure gauge to check the operating pressure of the AC. Also, look for oil stains on the connectors and valves. Refrigerant leaks often leave behind oil traces, so if you see grease, it could mean there's a leak. By following these steps, you can get a better sense of whether your air conditioner needs a refrigerant recharge. Always remember, if in doubt, it's best to consult a professional technician to ensure everything is working safely and efficiently. By Chen Wei, Beijing Business Daily Reporter
