Air conditioner not cooling? 3 ways to tell if it's low on refrigerant, beware of repairmen scamming you out of money
Many friends nowadays are saying that their home air conditioner's cooling performance is far worse than before. It used to be that setting it to 26°C made the house nice and cool, but now even at 22°C it doesn't feel cool at all. It's really uncomfortable, and the electricity bill just keeps climbing! Many people say the repairman told them this situation means it's low on refrigerant, and just adding some refrigerant would fix it, right? But is your air conditioner really low on refrigerant? Actually, you don't know how to judge that yourself. Now the editor will teach everyone 3 ways to judge for yourself whether it's low on refrigerant, so you don't have to rely entirely on the repairman. You can judge for yourself, and it won't be so easy for the repairman to cheat you out of your money!
1. Touch
There are requirements for where to touch too. We shouldn't just feel the temperature of the air, but rather touch the condenser fan at the back of the air conditioner. If this spot doesn't feel cool at all when you touch it, but the compressor is still working normally, that means the air conditioner really is low on refrigerant, and you still need to add refrigerant promptly.
2. Look
We can look at the air conditioner's condensate water. If the water comes out fast and in large amounts, that means the air conditioner's cooling performance is still very strong right now. But if the air conditioner produces very little water, and slowly too, that means the air conditioner is low on refrigerant, cooling weakly, and needs refrigerant added.
3. Feel the air
The air blown out by the air conditioner's outdoor unit, as everyone knows, is normally relatively hot air, so people avoid walking near it when they come across it outside. But if the air it blows out isn't very hot, that means it's low on refrigerant and needs refrigerant added. However, if your home's air conditioner outdoor unit is mounted outdoors, absolutely do not stick your head out to feel it yourself, bro, safety first!
