Top 8 Tips To Make Your Car’s AC Colder
I am a serial entrepreneur and a consumer advocate. When I’m not helping car buyers, I love working on ventures that have a positive impact.
A car air conditioning system has become one of the most prominent additions to the automotive industry.
If you live in predominantly hot countries, you know that the AC plays a vital role during the summer. However, we're often left wondering how to make the AC colder in the car.
This article aims to comprehensively analyze the various causes of car AC issues and the tricks to improve its efficiency. Most of the time, motorists think the Freon only causes the issue. However, regular maintenance and service are the factors that contribute to the issue.
Although various additives can improve the cooling effect of the car air conditioning system, it's still important to note that the actual amount of cooling you get depends on your daily routines.

Why Is My Car AC Not Very Cold?
There are several reasons why the car AC might not be very cold. These reasons include the following:
1. Your Car's AC Needs a Recharge
A common reason why car air conditioning units don't get cold enough is that they need to be recharged.
This can be done yourself, but you must make an appointment with a professional shop to do it properly.
2. An AC System Refrigerant Leak
Since a leak can prevent the car AC from being cold enough, a professional mechanic can use ultraviolet fluid to check the condition of the car's air conditioning system.
This method involves introducing a small amount of ultraviolet fluid to the system to show the presence of a low-pressure leak.
3. Fan Motor Failure
Can I Make My AC Colder?
Yes, you can. If your car's AC is not cold enough, you can make it colder. Several factors might be responsible for the anomaly, so it is important to consult a reputable professional to diagnose the issue.
How to Make AC Colder in Car
If your car's air conditioning unit is only blowing hot air and is not cold enough, you might wonder how to make it work again.
Follow these easy steps to improve the efficiency of your car's air conditioning system:
1. Park in a Shade
One of the easiest ways to keep the car AC cool is by regularly parking in the shade. According to a CDC report, vehicles parked in direct sunlight can experience a temperature rise to 172 degrees Fahrenheit.
To prevent the building up of heat inside your car, you should always avoid leaving your windows cracked. Also, park in a garage or shade during the summer season.
Sunshades are also essential to keep the interior of your car cool. They block the ultraviolet rays that can cause discoloration and cracks on the dashboard and windows.
2. Wind Down the Windows
If you don't have a sunshade for your car, you should also consider leaving your windows open to block the greenhouse effects of the sun.
Doing so will prevent the build-up of heat inside your vehicle. However, you should not leave your windows open while parking in public.
3. Don't Recirculate Air
The cooling system recirculation mode is also known to have one drawback. It allows the car to import cold air from the front of the vehicle and then return it to the system.
This feature prevents the air from getting to the back seats.
4. Switch on the Fan
After getting inside your car, open the back window and turn on the fans to allow ambient air to circulate inside.
After that, please turn on the air conditioning unit and tune it to a higher level. Doing so will allow the system to work correctly and keep the car cool. However, don't turn the AC to "max cool" immediately after you've gotten inside. Doing so will not allow the system to work correctly.
Turning the AC to "max cool" will only result in the system working harder to extract and cool the air inside the car.
Doing so will not allow the vehicle to cool appropriately. Instead, you should turn the fan to a higher setting and let the hot air escape through the windows.
Regular maintenance is also essential to ensure the car's components are working correctly.
5. Replace the Clogged Filter
Cars come with a cabin filter to prevent dirt and debris from blocking the airflow into the vehicle's interior. Unfortunately, over time, this feature can be stopped.
Getting the cabin filter cleaned is also simple and effective maintenance that you can do yourself. Doing so will allow the car's components to work correctly and keep the vehicle running smoothly.
6. Check the Refrigerant Level
Make sure that regular maintenance is also included in your schedule. For example, having your HVAC technician check the Freon level will allow you to know when and how much of it is inside your vehicle.
Low Freon levels can affect the performance and cooling of an air conditioning system. Having an appropriate level will allow you to make your AC work efficiently.
7. Use the AC Regularly
AC units need at least 20 to 30 minutes of use per week to maintain their working condition. So even though you may not want to use it, you should regularly use it to keep the car running smoothly.
8. Service the Car AC Regularly
Although you should also regularly service the engine, keeping the car's air conditioning unit in good condition is essential. Doing so during the winter season will allow it to work correctly.
Although you might be able to get a discount on maintenance during the summer season, the fee will increase once the demand for repairs increases.
Will Adding Freon Make AC Colder?
The Freon level may be low if your car's air conditioning unit is not blowing cold air. Adding more Freon will help improve the system's performance.
Unfortunately, even though an air conditioning system is designed to prevent leaks, the Freon level might be low.
Therefore, adding more Freon will not solve the issue. If the problem is still not resolved, it's essential to contact an expert for immediate assistance.
How Cold Should My Car AC Be?
The air conditioning unit works properly if your car's temperature is below 45 degrees Fahrenheit. However, if it's above that, you might require additional cooling.
If you notice that your car's air conditioning unit is failing, it's essential to check your insurance policy and the car's warranty. Usually, the issue can be covered under the vehicle's mechanical breakdown insurance.
How Often Should a Car AC Be Recharged?
We rely on our cars for various reasons, such as adjusting seats, GPS units, and auto-everything. We also expect our car's cooling system to keep us cool.
However, until the summer, we usually take for granted how much we appreciate our car's AC.
Since your car's AC system might not work correctly, you should regularly recharge it. Doing so can help prevent it from happening on a road trip. You can also schedule an AC recharge once a year or two.
Before your unit stops producing cold air, you must schedule an AC recharge.
How Long Should Car AC Take To Get Cold?
Learn how to cool down a hot car's interior faster by opening its door. You're about to head home after a long day, and you're confronted by a wall of heat, trapping you inside your vehicle. How can we get the car's interior temperatures back to normal?
The answer depends on the car's condition and how hot it is. For instance, if it's parked outside all day and the temperatures reach 120 degrees Fahrenheit, the time it takes to get cold depends on the car's air conditioning system. So, to cool down a hot vehicle quickly, we'll talk about how to do it in just a couple of minutes.
The first thing you should do is roll down the windows. Doing so will allow you to cool down the car's interior without going into it.
After rolling down the windows, start the car and start moving. You should start the vehicle because the car's air conditioning system needs to move air over a specific part of the car before it can begin working. This is faster than the radiator fans can do, allowing the car's cooling system to work harder.
After you've forced all that air over the condenser, it's time to bring the heavy artillery to bear on your car's cooling system. To start it, crank the AC dial to max. This will turn the system into recirculation mode.
The process should take around 5-10 minutes, depending on the car's condition. However, even though the vents are open, the car's interior may still get hot.
