You might be surprised to learn exactly how your auto air conditioning system works. While it’s commonly assumed that the AC generates cool air, that’s not quite the case. Actually, it blows hot air, with all the heat removed through a peculiarly complex, multi-step process. In a nutshell, your auto air conditioning works by condensing the refrigerant (Freon), which in turn raises its temperature. This passes through a dryer, where contaminants and moisture are removed, then into an accumulator where it’s slowed down further, leading to a loss of both pressure and temperature. The evaporator then cools down that air further still before the ventilation system pushes it out—and you experience it as a blast of chilly air!
Contrary to popular belief, your auto air conditioning doesn’t simply create cool air. Actually, the process is quite a bit more complicated and multifaceted than that. It begins when the compressor condenses your vehicle’s refrigerant—raising its temperature and sending it to the condenser, where it begins to lose heat. Passing through a dryer, the air is stripped of pollutants and airborne contaminants. In the accumulator, it’s cooled further still, and also depressurized. It eventually makes its way to the ventilation system, where it’s cooled down completely, and is released into your cabin as nice, refreshing air.
The auto air conditioning is an important part of your vehicle, without question—but not just for the obvious reason. Sure, it helps you and your passengers remain cool during the summer months. In addition, your air conditioning system allows you to demystify your steamy windows during the cold months of winter. And don’t forget that the auto air conditioning maintains air quality within your cabin, stripping the air of pollutants and contaminants. All told: It’s an important system, and worth taking care of with regular air conditioning service.
As for when it’s necessary to get your AC looked at, the short answer is: Any time you find that you’re not getting cool air like you used to. Additionally, it’s typically smart to have an AC check once or twice a year, as part of your preventative maintenance. This helps you keep ahead of any potential problems, resolving them before they turn into bigger or more expensive repair needs.
Responsible car owners get their oil changed about twice a year. They get their tires rotated, as well. They might do this work themselves; more likely, they go to a service station like Meineke in Cartersville GA. As you show diligence to these routine auto maintenance steps, don’t forget about your auto air conditioning. Your auto air conditioning works harder than you might think: It takes hot air and cools it, cleans out contaminants, and removes extra moisture. Through a multi-step process, it moves cool air from your refrigerant (Freon) to the vents, where you finally get to experience cool, refreshing air in your cabin. That’s a lot of hustle, so it’s no wonder your auto air conditioning needs some TLC from time to time.
Certainly, you should be getting an AC check as part of your regular vehicle maintenance. This helps you to stay on top of any potential issues, and address small problems before they become big ones. Getting an AC check once or twice a year, perhaps when you get your oil changed or tires rotated, can be a great way to invest in the lifespan of your car.
