What can be worse than car air conditioning that blows hot air on a warm summer day. The cause behind this problem might be insufficient refrigerant levels in the air-conditioning system, requiring a recharge. The cooling fluid called refrigerant was previously known as "Freon."

This culprit holds responsibility to generate cold air and circulates through a sealed system. Under regular conditions, it should not leak or need extra overhauling, but seepages can happen at numerous connections and components, resulting in inadequate refrigerating performance.

Recharging the air conditioning is the solution for this issue that involves adding the cooling fluid to the system, and in some conditions, it is able to resolve the problem, especially if there is a slow seepage.

If the leakage is bigger, it might not work but you must try this first because some refrigerants even contain a leak-sealing chemical to temporarily fix the problem. Do-it-yourself (DIY) recharging kits are available in the market, which give you a can of refrigerant, a hose, and a gauge, making it moderately stress-free and budget-friendly to attempt the recharge.

Keep in mind that if the cooling fluid leaks out rapidly, now you need to take services of professional mechanic on the grounds of the complexity.
