Understanding the Need to Recharge the AC Gas
Most modern AC systems today are operated using a compressor that functions to circulate the chemical refrigerant through the system to make sure that cold air is produced. AC systems operate using two sides the low and the high side. The refrigerant first starts as a gas in the system’s low side, and it is then converted into liquid form as it travels to the high side. The continuous circulation of the chemical through the low and the high pressure of the AC systems is what allows it to keep its environment cool
AC systems are pressurized so; it is crucial that they are properly sealed off for them to function the way they should. Over time though, wear and tear can cause the pressurized systems to start developing leaks. The moment that a leak begins, the possibility of the refrigerant to leak out is going the there, and it may even reach a point where the AC will lose all of it capability to keep producing cod air.
It is when the level of refrigerant in the AC system has dropped very low that there is going to be a need for it to be recharged. Pressured refrigerant needs it be recharged into the system for it to start functioning properly again. This important knowledge when you want proper AC maintenance. Being aware of the symptoms that your AC needs recharging of this gas is crucial.
Loss of cooling capability
This is considered as the most obvious sign that you AC is no longer able to possess enough amount of refrigerant to keep things cool. If you used to feel the AC being able to produce cooler air before and now it does not seem to appear so, then it is a time that you will take a look at this refrigerant level. This is because more often than not. There is a need for you to get it recharged.
Failure to engage the AC clutch
If you will set the AC control to its maximum coldness, it is expected to hear a clicking sound. This is a sign that the clutch of the AC is engaging. A signal from the pressure switch of the AC engages the clutch which then, in turn, reads the overall level of pressure in the system. When the level of the refrigerant drops way too low, the pressure switch is not going to activate. As a result, the clutch will fail to engage. The system then fails to circulate the low amount of refrigerant that is present, and as a result, it stops working and producing cold air as it should.
Visible leak signs
Another serious sign that you need a recharge is when there are visible signs of an air-con leak. If they are ever any signs of some greasy film along the fittings or the components of the AC, then it is important to have it checked as there is a very good sign that you are losing refrigerant.
Be aware that the reason why the refrigerant started leaking has to be addressed first before it should be recharged. A do-it-yourself method might not work in this case. Otherwise, you will just start leaking again and face the same dilemma all over without ever really getting to the bottom of the issue.
