How to Keep Your Car Cool in Summer
Nobody loves a sweltering hot car in the hot summer. Fortunately, there are ways to keep the car interior cool that are simple and affordable. Here’s how to keep a car cool in summer:
Using Water or Ice
One of the best ways to regulate the temperature efficiently is by keeping the body hydrated. You should consider drinking at least 8 glasses of water per day. While traveling, keep cold drinks in a travel mug or insulated thermos so they stay cold for a long time.
You can also put an ice pack, cold water, or direct ice on the back of your neck or wrists. Placing something cool on these points will help you cool faster. Additionally, you can put a block of ice in a pan near the floor vents to keep the air cool. If you're planning longer car rides, consider bringing a backpack of ice in an insulated cooler.
Dressing Appropriately
If you are traveling in a car during a hot afternoon, you should wear loose clothing in lightweight fabrics such as cotton or linen. Tight clothes trap heat against the body, whereas lighter ones sit away from the skin and feel cooler.
When deciding the color of your clothing, you should consider wearing light-colored clothing that reflects the sun. For example, white-colored clothes don't absorb as much heat from the sun and keep your body cooler.
Keeping Inside of the Car Cool
You should roll down at least two windows to ensure proper car circulation. If your car has a fan-operated fresh air vent, consider turning it on and opening the rear window to draw hot air out of the vehicle. You can also open the car's sunroof or back window to let more fresh air enter the vehicle.
If it is legal, you can consider installing window tinting on the windows and windshield. This will reduce the amount of sunlight that directly comes into the car. It also protects the interior from UV radiation and damage to the car's dashboard. You can even hang a damp rag on the fan for an extra cool area.
Changing How and When You Travel
You should consider driving in the coolest times of the day in the hot summer months, like night or early morning, and avoid driving in the mid-afternoon. Additionally, you should avoid driving in traffic where there is no airflow.
For example, bumper-to-bumper traffic means the vehicle will hardly move, and no air will come in and out. Remember, the more time you spend away from direct sunlight, the cooler your car will be. Roadways and tree-lined streets are shadier than open highways, so travel more in shady areas.
Park in the Shade
One simple way to cool the car is to park in the shade or cover the area to block the direct sunlight. You should look for trees, shadows from tall structures or buildings, or parking garages to keep the car cool from inside. If there's no shaded area nearby and you want to park the car for a long time, you can consider creating a shaded portion by placing sun shields on windows that are exposed to sunlight.
Use a Dashboard Cover
You can put a cover on the car's dashboard to keep sunlight away from the car's interior. When you do not have to touch plastic surfaces or hot vinyl, it will make you feel less overwhelmed by the heat.

Car AC Alternatives
Portable air conditioners or car ACs serve as cooling systems that can keep the inside of your car cool and comfortable in hot summers. However, portable ACs are more reliable compared to car ACs. This is because car ACs are often unreliable, overburdened, and might stop working in the middle of the journey. That's where portable ACs act as a lifesaver. If you are looking for more car AC alternatives, we have explained the different options below:
Portable AC
Portable ACs are ideal for cars and vans. They can quickly cool the space and keep it comfortable throughout the journey. Most portable ACs can be connected to a power source or plugged into the car's cigarette lighter. When not using the portable ACs in the vehicle, you can carry them to your home or enjoy outdoor activities without feeling hot.
Portable Fan
If you're looking for a cost-effective car AC alternative, you may consider a portable fan. These fans are designed to circulate air within the vehicle and offer an enhanced cooling effect with the increased airflow. They have low energy consumption and do not require any installation. However, their effectiveness depends on ambient temperature.
DIY Fix
There are many simple DIYs that will help you cool the car without spending a lot of money. For instance, you can place a bowl of ice in front of the portable fan to create an evaporative effect. Alternatively, you can hang a wet cloth before the partially open window to create a cooling effect.
Solar Generator for Portable Fan/AC
Portable solar generators are designed to charge portable fans and ACs in cars, so you never have to worry about hot weather. Jackery Solar Generators are portable, powerful, and efficient charging solutions that can be taken during outdoor adventures. The portable power station's foldable handle and large capacity ensure that you can charge portable fans and other cooling devices in the car for long hours.
Seat Covers or Car Covers
There are specialized seat covers and car covers available to keep the car cool by reflecting sunlight and reducing heat absorption. For instance, reflective seat covers reflect UV rays and insulate against heat. While the reflective seat covers only the car seat, the car covers are designed for the entire car.
Car AC Maintenance Tips
Whether you're driving an old car or a brand-new one, maintaining the car's AC is essential. Here are some critical tips to keep the air conditioning unit operating at maximum capacity.
Routine Car Washes
Routine car washes help remove dust, debris, and dirt to maintain the car's AC system. When the car's condenser coils are clean, they can dissipate heat more effectively to improve cooling performance.
Optimizing Airflow and Temperature Control
When the blower motor is cranked and the temperature is at full control, the AC might not work at its best. Thankfully, some optimization and temperature control can help. For instance, turn the temperature to cold, set the fan one notch down from full blast, set the direction of air to feet and dash vents, and turn on the recirculate mode for effective cooling.
Checking and Replacing Cabin Air Filters
If you think the air flowing from the vents is not cool enough, it could be because of dirty or clogged cabin air filters. When there is a buildup of airborne particles and debris in the vents, air does not pass through the air filters anymore. You can change the air filters to restore the cool air.
Refrigerant Levels and Recharging
Sometimes, even after maintenance, the car AC does not perform well. This is because refrigerant can dissipate slowly from seals, and you'll need to recharge the refrigerant to restore the performance you are used to.
Insulating and Reflecting Heat
A windshield sunshade is an excellent method of keeping the inside air cooler—or not as hot as it could be. The efficient windshields can insulate the car from UV rays, and the reflective material can send the rays back outside.
Upgrading Your Car's AC System
A leak in the AC system can affect the overall working of the air conditioning unit. For instance, a simple seal or pinhole in the low-side or high-side line could be the issue. It could also be a fault in components like a compressor, condenser, or evaporator. If that's the issue, recharge will only work for a short time, and you'll need to schedule repair if the problem persists.
