Why Does Your Air Conditioning Need Recharging?

Summer is approaching, and it might be a good idea to check the car AC once before you take it out for a ride. The last thing you want is to be stuck with a dysfunctional air conditioner during a heatwave. We seldom pay much attention to the air conditioning system unless it malfunctions. A vehicle's air conditioner works on a closed system. A closed system means the air conditioner recirculates the same refrigerant to cool the air. However, if the air conditioning needs a recharge, it is possibly due to a leak, component damage, or some malfunction. 

In this article, we will discuss: 

• Signs that you need to recharge your Car AC 
• Is it essential to top up the refrigerant or coolant regularly? 
• How frequently do you need to recharge the AC coolant?

Your Car AC Needs A Recharge

Here are some signs to help you determine if your car’s AC needs a recharge and why it is essential to schedule one if you have one of these signs or multiple of them.

• It is warm: This one is pretty easy to spot, isn’t it? If you switch on the car AC and it blows out hot air instead of cold air, it might be time to recharge your AC. This is the most obvious and one of the most common signs to recharge your AC. However, before you spend on recharging the AC, it will b good to check if a dirty and clogged filter is blocking the cool air. It is also a good idea to keep the filters clean. 
• Clutch doesn’t click: You should be able to hear a slight click when you switch on the AC. However, if the refrigerant levels are low, you don’t hear the click, and the AC doesn’t start cooling your car, it might be time for that mechanic's visit. This problem arises even if the compressor is too old. 
• Leakage: More often than not, the refrigerant leaks. If you find a puddle of refrigerant under your car or a greasy coating on the AC vents, it's a clear sign that the refrigerant has leaked and will need to be changed almost immediately if you need the car’s AC to work. 
• Glitchy Condenser or Compressor: If the compressor or condenser of the car AC glitches, it might cause a malfunction. Both usually last as long as the car does with minimum maintenance. However, there are cases where the compressor or the condenser develops issues. Wear and tear, clogs and jams, or just age-related malfunctioning are common. It is important to identify the problem immediately and take care of it as soon as possible. 

Is It Important To Recharge Your AC?

The short answer is no! Your car AC might not need a coolant top-up if there are no signs of leakage or if it is functioning correctly without any glitches. Mechanics sometimes make extra money by claiming that the car’s air conditioner needs a regular top-up. You don’t need to replace AC coolant as frequently.

How Frequently Do You Need to Recharge Your AC?

It is in your best interest to keep the car AC recharged. However, there is no hard and fast rule that you should do it annually. It needs to be topped up only if there are clear signs of leakage or the AC is not functioning efficiently. Your AC loses some coolant over time. However, this loss is not so much that you must top it up yearly. You should check with your mechanic. With diligence and awareness, you can judge the best time to get a recharge done. 

Summary

If your AC needs a recharge, chances are that there is something amiss in your car’s AC system. You don’t need to recharge your car AC often because it works in a closed system. In other words, the same pump recirculates the same coolant, which minimizes external risks. However, there are times when the filter is too clogged or the vent is jammed. Check for all possible reasons why the air in the car is not being cooled before recharging the AC. Your car AC might not need to be recharged at all.
