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!
An AC recharge is only needed, strictly speaking, when you notice that your air isn’t as cool as it used to be. With that said, routine inspections to your auto air conditioning can keep your unit from developing bigger problems, so it’s not a bad idea to ask for auto AC service when you go to get your oil changed and your tires rotated.
The good news is that you won’t need to have serious work done to your AC very often. Indeed, most drivers go through just about 15 percent of their refrigerant per year, and other problems happen only after many miles have been accumulated. With that said, preventative maintenance helps you spot potential issues and minimize their impact—so scheduling a routine AC service call at Meineke in Louisville KY is recommended.
The good news is that most vehicle owners don’t have very frequent auto air conditioning problems—and you can minimize the risk further still by investing in a routine AC check. Having an AC recharge every year or so is likely enough.
There are a couple of reasons why you might eventually need to have some air conditioning repair work done. One, speaking generally, is that your air conditioning system does a lot of hard work, and eventually that heavy lifting will lead to wear and tear. Any one component of the system can break and throw the whole thing off; an AC check will help you identify and correct problems before that happens. Additionally, you’ll eventually run low on refrigerant, which is a critical ingredient in keeping your cabin cool. That’s when an AC recharge is needed.
How well do you understand the workings of your auto air conditioning system? Many drivers are surprised when they learn that their auto AC doesn’t simply push out cool air, but rather it starts with warm air, cools and depressurizes it, filters out its contaminants, and then—at the end of a multi-stage process—it finally pushes that cool air into the cabin of the vehicle. If that sounds like a laborious undertaking, well, it is. The auto air conditioning takes on a lot of wear and tear. It goes without saying, then, that regular maintenance is a must.
