One of the most revolutionary developments in automobile history is the air conditioner. During the hotter months of the year, air conditioning is a need in countries like Mali, Burkina Faso, and Senegal. Having reliable automotive air conditioning is crucial, but what exactly causes the air conditioning to be cold inside a vehicle?

Causes and solutions for how to get your car’s air conditioner to work better are broken down here. Most drivers believe that only Freon can keep their air conditioner cool. Some people may view it as simply routine maintenance of the AC system.

Certainly not! Although there are chemicals that may be added to a car’s air conditioner to make it chillier, the truth is that the amount of cooling produced by the system is determined by how often and for how long you drive.


A Comfortable Drive

Using the air conditioner in your automobile is beneficial for reasons other than your comfort. If you turn on the air conditioner, you won’t have to suffer through the oppressive heat of driving in the summer. Instead of cranking up the volume by opening the windows, you may listen to your favorite tunes while staying cool with the air conditioner.

Better Safety

If you use your air conditioner, you’ll be safer on the road. One benefit is that being too warm no longer causes you to feel sleepy. Turning on the air conditioning will offer you with healthier, cleaner air, which will help you stay awake and focused.


Second, the windshield mist can be mitigated by turning on the air conditioner. When there’s moisture in the car, the best approach to clear the windshield is to turn on the air conditioner.


Worse Fuel Economy

The negative impact of air conditioning on fuel economy is probably the best-known drawback of having it installed in a vehicle. You can save money on gas by opening the windows instead of running the air conditioner on short trips. Air conditioning uses gasoline to run and can raise your fuel usage by as much as 20%. You may end up saving a lot of money in the long run.

How To Make Car AC Colder

How can I get my car AC to blow colder again if it has stopped blowing cold air and instead blows warm or hot air? You’ll get to the good stuff in a minute. To get the most out of your air conditioner, all you have to do is follow the advice in this article.

You should think about a number of different suggestions and shortcuts. From how you store your belongings in the car to the regularity with which you perform maintenance. These tweaks will help your air conditioner run more efficiently.

Before delving into the more technical aspects of how to make your can air conditioner cooler, be sure to check out the helpful do-it-yourself hints first.

Park in a shade

Maintain your car’s air conditioning by keeping the interior cool. One strategy for doing so is to always seek out parking in the shade.

When the outside temperature is between 80 and 100 degrees Fahrenheit, the interior of an automobile parked in direct sunshine can reach temperatures between 131 and 172 degrees Fahrenheit, as reported by the Centers for Disease Control and Prevention.

Do not jeopardize your safety and security in an effort to keep the interior of your automobile from getting too hot. Don’t do things like leaving windows open or winding them down.

Never leave your car out in the open during the summer; use a garage or covered parking spot instead. There is no way around building a garage in your apartment if there isn’t one already there.

Sunshades’ primary function is to prevent your vehicle from becoming an oven on hot days. They also protect the car interiors from UV Rays which cause cracks on the windows and dashboard discoloration.

Wind down the windows

Leave your windows cracked if you don’t have a parasol in your compound. This will prevent heat buildups caused by greenhouse effects.

Do not, as I have already said, put your safety at risk. However, when leaving your baby ride parked in a public area, you can’t roll down the windows.

Don’t recirculate air

There is one drawback to using the recirculation mode of the cooling system in your vehicle. It pumps chilly air out the front of the vehicle and brings it back inside.

This will restrict airflow to the rear passengers. If there are people in the back seats, consider turning off the recirculation function.

Switch on the fan first

Let’s say you get into a hot car and it stays that way as you drive. Let the breeze in by rolling down the rear windows and cranking up the air conditioning. Allow the fan to blow the hot air outside and open the windows.

After that, it’s time to put on the air conditioning and set the thermostat a notch or two higher than minimum. Close the rear window winders and keep on driving.

Although it may be tempting, resist the urge to set the thermostat to its maximum cooling setting. This is because switching the AC to ‘max cool’ the moment you get inside is not the right way to make it colder.

It may be tempting, but resist the urge to set the thermostat to its maximum cooling setting. This is because turning the air conditioner to its coldest setting as soon as you walk through the door is not the best strategy for reducing the temperature inside.

Use these suggestions to get a more frosty automobile air conditioner. You know that keeping up with routine maintenance is essential for your car’s parts to continue functioning optimally.

If you want your car’s air conditioning to blow cooler, it’s important to keep up with routine service. To begin, let’s go through some of the fundamental repairs that need to be made when your car’s air conditioning is not producing sufficient cooling.

Clean/replace the clogged filter

In order to keep the interior of a vehicle clean, manufacturers install cabin filters. Unfortunately, the cabin filter eventually becomes clogged with dirt and debris. If the filter is clogged, the air conditioner won’t be able to cool the interior.

Cabin filter cleaning and replacement is one of the few maintenance tasks that may be done without the help of a mechanic. Make sure the filter is frequently cleaned, and if it gets too dirty or clogged, consider replacing it.

Use the AC regularly

Don’t forget to turn on the air conditioner once in a while. Using the air conditioner for 20 to 30 minutes once a week, even if you don’t want to, will extend its life. The air ducts won’t get clogged up this way either.

Check the refrigerant level

Create a regular maintenance plan for this. Always have your car’s Freon level checked by a professional. This way, you can keep track of the frozen food supply and restock when necessary.

An air conditioner’s cooling and efficiency suffer when refrigerant levels are low. If you want a cooler flat by using your air conditioner, check the refrigerant level to make sure it is at the right level.

Why Isn't My Car AC Blowing Cold Air?

Service the car AC regularly

Maintaining the air conditioner is similar to maintaining the engine of a vehicle. The air conditioner, however, does not require as frequent servicing as the engine. It’s preferable to get it checked out after winter’s conclusion.

Maintenance fees are reduced as spring gives way to summer. However, the technicians will increase the upkeep price because of the high demand throughout the summer.

10 Tips in Maintaining Your Car’s Air Conditioning System

1. Have it Cleaned by the Pros

Having your car’s A/C professionally cleaned will keep the air cold and fresh for as long as possible, which is why so many Welshpool locals recommend the service. After all, they have the tools and training to do a proper job of cleaning the AC unit.

2. Regular Professional Maintenance Is a Must

Having your car’s air conditioning frequently serviced by a qualified mechanic is essential. Expert mechanics can quickly diagnose any problems with the air conditioning in your vehicle when given the opportunity to check it out.

3. Don’t Always Rely on DIY Jobs

It’s preferable to let a professional mechanic handle repairs to your car’s air conditioner, even if you believe you have experience doing so. The experts have the knowledge, training, and equipment to repair your car’s air conditioning without endangering your vehicle in the process.

4. Have the Problems Addressed Quickly

If your car’s air conditioner starts acting up, don’t wait to take it to a local Welshpool service center. Symptoms of a failing air conditioning system should not be ignored because they might spread to other parts of your car, such as the wiring.

5. Let the A/C Run for About 10 Minutes Every Week

Maintaining proper gas pressure in the air conditioner can be accomplished by running it for just 10 minutes once a week. Having the air conditioner in good working order throughout the heat is another benefit. However, you should use the system’s coldest temperature and fastest fan speed for this.

6. Let the A/C’s Defrost Mode Run for About 5 to 10 Minutes

The defrost setting on the air conditioner should also be left on for around 10 minutes. In doing so, you will prevent mildew growth and associated musty odors by getting rid of the system’s surplus moisture.

7. Remember to Recirculate the Air From Within

When the temperature outside is particularly high, turning on the air conditioner’s recirculation mode will help keep the car’s interior comfortable. By simply consuming energy to cool the air inside the cabin, this setting is ideal for saving money on utility bills.

8. Keep the Car’s Interior Clean

The efficiency of an air conditioner can be diminished by the presence of dust, grime, and other particles. You should therefore frequently vacuum the carpets, mats, and seats in your vehicle.

9. Don’t Pre-Cool Your Car

It’s nice to get into a cool automobile on a hot day, but doing so may reduce the effectiveness of the air conditioner. The efficiency of the car’s air conditioner is enhanced by the presence of a breeze. Therefore, turn on the air conditioning as soon as the car begins to go down the roads rather than waiting until the inside temperature drops.

10. Park Under the Shade

If you leave your automobile in the sun for an extended period of time, the temperature inside will rise significantly. This means the car’s air conditioner will have to work more than normal to maintain a comfortable interior temperature. Parking in the shade or installing sun blinds is a simple solution to this common issue.

Staying cool during Australia’s summer months will be easier if you keep your car’s air conditioning system in good shape. Plus, if you make it a habit of following these A/C maintenance tips regularly, your vehicle’s air conditioner will remain efficient all year round.


Q: Why is my car AC not cold enough?

Maintaining a functional car air conditioner is essential throughout the hot Australian summer. In addition, if you make it a habit to follow these A/C maintenance guidelines consistently, your car’s air conditioner will continue to function well throughout the year.

Lack of refrigerant: Low Freon levels are the most common reason for an air conditioner’s inability to produce cold air. A little or undetected leak in the system causes low refrigerant levels.

While it’s not very frequent, having too much pressure in the system can have the same effect on the AC as having too little refrigerant. High pressures are produced by the overabundance of refrigerant in the system.

Failure of the air conditioner’s compressor can occur rapidly if it is operated with insufficient oil. When the air conditioner’s compressor stops working, the temperature inside quickly rises.

Problems with the radiator fan, poor sensors, clutch failure, system limits, and air/moisture contamination are also common reasons for an air conditioner to stop producing cold air.

Q: Does adding Freon make AC colder?

Low levels of Freon can be the culprit of a car air conditioner that isn’t producing chilly air. If that’s the case, topping off the Freon tank will bring the temperature down.

However, leaks in an AC system are impossible to engineer. A modest or undetected leak is likely to blame for low Freon levels. The addition of Freon will not help the situation. Akin to putting water in a can that constantly leaks. A qualified ASE technician should be called in to identify the source of the problem and resolve it.

Q: How long should it take for car AC to get cold?

The temperature inside the car, the cooling method you choose, and the health of your air conditioner are just a few of the variables that influence the result. For instance, if the vehicle is left in the sun all day, the interior temperature should reach between 120 and 135 degrees Fahrenheit.

Your air conditioner in the car should be cool in around 5-10 minutes regardless of the strategy you use. Keep in mind that even if the dashboard vents are set to blow cold air, the car’s interior can still radiate heat.

Q: How do I supercharge my AC?

If you’re handy around the house, supercharging an automobile’s air conditioner is a service you may offer. However, topping off the gas tank of a car’s air conditioner is a rather easy task.

Using the compressor’s two lines as a guide, find the air conditioner’s low service pressure port. The port for low-level service is marked with a “L” and is smaller than the other ports. Use your thermometer to get a feel for the temperature outside.

Placing a temperature gauge in close proximity to the vents will allow you to monitor the temperature while the air conditioner is running. Let the air conditioner run for a few minutes. As the temperature drops, the needle on the thermometer will move down a notch.

Plug in the power supply and adjust the temperature dial to the current room temperature. Join the other end to the port designated for low-level service. It’s important to give the refrigerant a good shake before using it again. Shake it slowly when charging to maintain charge.

You can remove the charging cable from its port once the battery is fully charged. If you want to see a visual breakdown of how to recharge your air conditioner, ChrisFix has you covered.

Q: How can I cool my car without air conditioning?

You have to drive even if you don’t want to be stuck in a hot automobile during the summer. There is an endless list of advantages to having a car. Everyone needs a car at some point or another, whether it’s for commuting to and from work or dropping off the kids at school.

If your car’s air conditioning is broken, you may be wondering if there is any way to achieve a cooler interior temperature without using the system. The procedures are straightforward. It’s up to you, but you can try one of the following options:

  • Leave your car in a shady spot.
  • Put the windows down and open them a crack.
  • Get rid of the stifling heat indoors simply using the fan.
  • Use a frozen water bottle as ice.
  • Spread a damp towel over the vents.
  • Have damp hair and drive?
  • Put a cover on the dashboard
  • Purchase a little solar-powered fan.

Q: Does turning off AC make the car faster?

Simply said, absolutely. An automobile’s air conditioner is engine-driven. As a result, the air conditioning system causes a slight rise in the vehicle’s RPM when it is first turned on.

It’s having the same effect as before: increased gas consumption and a minor drop in engine efficiency. When the air conditioner is turned off, the car’s speed increases. However, the distinction may be too slight to matter.
