Air conditioning is often one of the first things people check when they buy a used car. You always want to make sure you can enjoy cool air when the inevitable summer heat comes calling. And, many people are familiar with basic things about their car’s air-conditioning unit like, how to turn it on, and even how to recharge it. But, here are some things you might not know about your car’s unit.

Air conditioners actually dehumidify the air

In a sense, air conditioners are designed to dehumidify the air. Even though they are not as efficient as dehumidifiers, their function still reduces the moisture in the air. Their dehumidifying effect is so strong that it actually prevents the formation of mold and mildew. Not that it’s something you’ll have to worry about in a car.

Air conditioners help prevent allergies

This function also relates to how they remove moisture from the air. Allergies are caused by airborne particles or allergens. When the AC unit sucks warm air out and cool air in, it also sucks the allergens from the air in the car. This doesn’t mean that your AC is enough to prevent any allergic reactions you might have. But, it does play a small role.

Regular checks can save you a lot of money

This fact applies both to your car AC and your home AC. ACs, like other machines, can grow inefficient over time. Their air can escape through unexpected holes and gaps, causing its operation to be inefficient. An inefficient AC means that you’ll consume more power to get the same output. Getting the AC checked regularly can help you identify these small gaps and save you money and energy in the long run.

There are a lot of reasons why your AC might be blowing hot air

A car air conditioning that can’t blow cool air is basically useless. Unless, of course, it’s winter and you need some warm air. But, more often than not, people need the AC for the summer. The reasons why your AC might be blowing warm air ranges from serious electrical and condenser problems to simple things like leaking refrigerant. Sometimes, you can fix the problem by simply visiting Super cool ac (http://supercool.ac/products/auto/ac-flush-kit-flush-tools/) and getting some parts. Other times, you need to have your mechanic do a complete check.

ACs used to make millions for the cinemas

A long time ago, during the great depression, households didn’t have AC units. But, movie theaters did. People would go to the cinemas just to enjoy the AC and cool down. The movies themselves were often people’s secondary reasons for showing up. Movie producers picked up on this and started releasing their biggest movies in the summer when the weather is hotter than usual.

Your car AC was invented in 1939

You almost get a breakdown when your car AC stops working, but did you know that there were no car ACs before 1939? Imagine what a summer road trip would have felt like then. That was until Packard Motor Car Co. developed a system very similar to what we have today that would enable cars to cool themselves in the heat. Inventors and engineers have since developed their model to give us sophisticated car cooling systems like climate control.
