How To Make Car AC Colder: Let’s speak about the air conditioner for a moment before we get into how to make it colder in your automobile.

All air conditioners, regardless of vehicle, operate in the same way. The air conditioning system in an automobile is made up of five basic components.

The air conditioning system is completely sealed. Or, to put it another way, it’s compressed from the inside by refrigerant (AC gas). In the repair manual, every car manufacturer provides the appropriate gas pressure. This usually weighs between three and four pounds. Let’s have a look at what each of these parts does:


The compressor compresses the AC gas to convert it to fluid and pump it through the refrigerant line, as the name implies. It’s named “high side” because the system is pressurized in this area.


A condenser is a radiator-like heat exchanger that assists in cooling the refrigerant after it has been heated during the compression cycle. The refrigerant goes through the condenser and is cooled by the air that gushes through it.

Expansion Valve:

An expansion valve is a pipe limitation. The high-pressure and low-pressure portions of the AC system are separated by this. The liquid refrigerant converts back into gas as it flows through this valve and reaches the low-pressure section.

The refrigerant enters the dryer in a gaseous state through the accumulator. The moisture in the refrigerant is removed in this way.


The evaporator is now used to pass the dry cold gas through. The evaporator is the only part of an air conditioning system that is located beneath the dashboard. This AC Fan then cools the hot air by blowing air through the evaporator core. Through air vents, this air is then blown into the cabin. The heat exchange is finished, and the refrigerant returns to the compressor to begin the process all over again.

Replace the cabin air filter if necessary.

The cabin air filter keeps dust, pollen, grime, and other contaminants out of your car’s air conditioning and heating systems. If the filter is blocked or unclean, it can reduce or even prevent A/C airflow, making it difficult for the chilly air you crave to reach the cabin.

You may be able to inspect and replace the filter yourself, depending on your car. For more information, consult your owner’s handbook. Don’t worry if you don’t feel confident replacing the filter on your own.

If at all possible, park in the shade.

By keeping heat from building up in your car, you may give your A/C a head start.

When the outside temperature is 80-100°F, cars parked in direct sunshine can attain inside temperatures of 131-172°F. Maintain a sense of safety and security by not leaving your windows cracked or half open. Instead, park in a shady spot.

In the summer heat, it’s perfectly OK to harness your inner-vulture and circle the parking lot for some much-desired shade! Alternatively, look for a covered parking area beneath an overhang.

If you can’t find a parking spot in the shade, make your own! Install a sun shade on your windshield to keep direct sunlight from turning your car into an oven. Sunshades can also help protect your car’s interior from UV rays, which can cause yellowing and cracking on the dashboard.

Boost the performance of your air conditioning system.

Are you looking for some genuinely relaxing music to listen to in your car? Reggae is only going to get you so far.

Restarting your refrigerant is a quick way to make your car’s air conditioner colder. We won’t go into detail on how automobile air conditioning works, but suffice to say that low Freon or refrigerant levels nearly always result in car air conditioning that isn’t chilly enough.

If you have an A/C gauge and thermometer, two pieces of equipment that are available at most auto parts stores, you can check your refrigerant level at home.

Don’t turn on the air conditioner to its maximum setting immediately away.

It’s tempting to put on the air conditioner and set it to “max cool” as soon as you get in the car. However, did you know? Starting the car with the A/C blasting isn’t the best method to get it cool! When your A/C is set to “max,” the car pulls air from the cabin, cools it, and then blows it back into the cabin.

The problem is that the air inside the automobile is hotter than the air outside when you first get in. (Remember how hot it can get inside your car? It can reach nearly 200°F!) You’re making your air conditioner work harder for no reason.

To make things feel cooler and faster, start by sucking air from outside the vehicle. First, turn off the air conditioning. Set the airflow to “outside” mode and crank up the fan to its maximum speed.

Then, once you’ve gotten some of the humid, hot air out of the car, turn on the air conditioner and set it to “recirculate” airflow mode. You can now adjust the air conditioner to “max cool.”

Don’t send mixed messages to your car’s air conditioner.

How can you keep the cabin cool once the hot air has been driven out? Turn the thermostat dial all the way down to the coldest setting.

Keeping the dial in the middle causes the car A/C to slightly reheat the air, which burns more gasoline and makes the car A/C system less efficient overall. Maintain the coldest temperature possible, then change the fan speed as needed.

Why isn’t my Car’s Air Conditioning Cold?

Freon leak

Freon is a chemical refrigerant that is used to chill warm air before it is pumped back into your vehicle. Because today’s air conditioning systems are so delicate and require a certain amount of freon to function, a leak can be a major problem.

A damaged hose, a leaky gasket, or even a weak connection can all cause a leak. To correct this, we must first locate the faulty components, repair or replace them, and then recharge the system with Freon.

It’s Time To Recharge Your Air Conditioning

Even the most efficient air conditioners can lose a little amount of refrigerant over time, usually so slowly that you won’t feel the difference. And you might never notice that your car’s current A/C low temperature has changed by more than a degree or two.

However, if you find that your car’s air conditioning isn’t working, you may be low on freon. It’s one of the most prevalent reasons why your car’s air conditioning isn’t as chilly as it should be.

It’s simple for us to identify if your air conditioner is leaking. Bring the automobile in and we’ll run some tests on it. If your refrigerant level is low, we can replenish your air conditioner.

The Blend Air Door has become stuck.

Warm air that runs over your engine enters your car when you heat it. When you turn on your car’s air conditioning and try to chill it down, a “blend air door” swings across your ventilation system, blocking the warm air from entering and allowing the cold air from the A/C system to enter.

When the mix air door gets blocked, no matter how well the rest of your car’s A/C system is working, you’ll just keep getting warm air.

Although replacing the blend air door rarely necessitates the purchase of new parts, it can be difficult to reach due to its location deep under your dashboard.

The A/C Compressor Isn’t Working

A compressor is at the core of any air conditioning system, and its purpose is to compress the freon. When the freon expands, it becomes extremely cold. When air is blasted across cold freon-filled metal, the air cools swiftly.

The air won’t get cold if your compressor isn’t working. Low freon levels, an electrical fault, or an overheated motor could all be reasons why your compressor isn’t working.

Condenser Blocked or Broken

The condenser’s job is to convert freon gaseous to liquid again. The refrigerant will not flow if the condenser is clogged with trash or is broken. When this happens, our air conditioner will not blow cold or even cool air.

Electrical Issues

It’s also possible that your car’s air conditioning isn’t working because of an electrical problem. Some components of your air conditioning system, such as your compressor, are electrical. It can also be disabled by anything as simple as a blown fuse.

It’s critical to have your car’s air conditioning running at all times in the United States, where temperatures can reach summer levels virtually any time of year. Come to AutoAid if you discover your car’s air conditioning isn’t working properly. Our mechanics can perform a comprehensive diagnostic test on your vehicle and tell you exactly what’s wrong with your air conditioning system.

Is it true that adding Freon to an air conditioner makes it colder?

Low Freon is one of the causes of a car air conditioner that isn’t blowing chilly air. If this is the case, more Freon will make the air conditioner cooler.

Air conditioning systems, on the other hand, are designed to not leak. If you notice a low Freon level, it’s most likely due to a small or undetected leak. In this case, adding Freon will not solve the problem. It’s the equivalent of putting water in a leaking can. Hire an ASE-certified technician to find and remedy the problem.

How long will it take for your car AC to cool down?

The answer is dependent on a number of factors, including how hot the car interior is, the cooling method you intend to use, and the state of your car’s air conditioning system. If the car is parked in direct sunshine all day, the inside temperature should be between 120 and 135 degrees Fahrenheit.

Regardless of the method you use to chill your car’s air conditioning, the entire operation should take no more than 5 to 10 minutes. While the dashboard air vents blow cold, the automobile interior might still exude absorbed heat.

How do I boost the power of my air conditioner?

You should learn how to supercharge a car’s air conditioner as part of your DIY maintenance skills. However, recharging a car’s air conditioning system is straightforward.

Follow the two lines that link to the compressor to find the AC low service pressure port. With a ‘L mark’ on top, the low service port is smaller. With your temperature gauge, check the ambient temperature.

Turn on the air conditioner and hang the temperature gauge on the air vents. Allow the air conditioner to run for 1-3 minutes. The temperature on the indicator will gradually decrease.

Connect the recharging adapter to the wall outlet and adjust the temperature dial to the desired setting. The other end should be connected to the low-service port. Before recharging, give the refrigerant a good shake. Then, while recharging, continue to shake it slowly.

After the recharge is finished, simply disconnect the port and you’re done.

Without air conditioning, how can I keep my automobile cool?

You must drive regardless of how much you dislike sitting in your suffocating car during the summer. There are a slew of reasons to get behind the wheel. You can’t avoid driving whether you’re heading to work, coming home from work, or transporting your kids to school.

Is it true that turning off the air conditioning makes the automobile go faster?

Yes, literally. The air conditioning system in a car is powered by the engine. As a result, when you start a car and switch it on, the automobile’s revolutions per minute increase somewhat to compensate for the electricity used by the air conditioning system.

Similarly, it results in increased gas consumption and a minor reduction in engine efficiency. An automobile will accelerate faster if the air conditioning is turned off. However, the difference could be minor or negligible.
