Why Do I Need to Recharge My Car’s AC?

Updated: Aug 6, 2021

If the air coming out of your AC system is running hot, then something is clearly wrong. Not to mention the fact that a hot car can be a nightmare in the dog days of summer. It’s possible all your vehicle’s AC system needs is a “recharge” to return to normal. But is recharging all you need? What does it mean to recharge an AC system? Let’s find out.

How Do You Recharge an AC System?

To recharge an AC system, you’ll need to head on over to your local auto repair shop to have a Certified AC Mechanic complete AC Performance Evaluation. This evaluation includes checking for the proper amount AC Refrigerant known as R-134. The Certified AC Mechanic will use a specific designed machine to install R-134 that prevents over pressurizing the system which could lead to blowing out seals, or causing more damage. Buying a can over the counter for DIY and installing Freon in the system can cost you.

Freon is the brand name of a chemical that the Environmental Protection Agency has deemed dangerous for the environment, and thus, is no longer manufactured in the US. However, how the word “kleenex” is used to describe facial tissues of varying brands, “freon” is often used in the same manner.

So, now armed with your refrigerant, you can recharge your system. However, before you do that, ask yourself whether or not you actually need to do so.

Do You Need to Recharge Your AC System?

Though the wisdom of local people is often based in personal, relevant experience, it is sometimes ill-advised. Your car’s AC system is a closed system. Put differently, this means you should never actually have to recharge it for it to function year after year.

Though it is possible that your car’s AC will function after being recharged, it’s also possible the true underlying cause of the leak will go unaddressed. Again, as a closed system, there should be no need for a recharge, so the real question is: What is the actual problem?

The answer is a bit more complicated than you may think. A leak in one of the hoses or from one of the connectors could be the trouble. You could also be experiencing a failing compressor. Unfortunately, you won’t know unless you take your vehicle into your local Columbia, MD auto repair shop.
