Check Your Refrigerant Level

If you’re wondering how to make your car AC colder, one of the first things you need to check is the refrigerant level. A low refrigerant level can cause your car’s AC to blow warm or cool air instead of cold.

To check your refrigerant level, you will need a few tools, including a refrigerant gauge and a can of refrigerant (if necessary). It is worth noting that adding too much refrigerant to your system can be just as damaging as not having enough, so it’s important to follow the manufacturer’s instructions carefully.

Use a Refrigerant Gauge

The first step in checking your refrigerant level is to locate the service port on your car’s AC system. This can usually be found under the hood or near the firewall. Once you have located the service port, attach the refrigerant gauge to it by following the manufacturer’s instructions.

The refrigerant gauge will show you the current pressure of your AC system. If the pressure is too low, this indicates that your system may be low on refrigerant.

Checking your car’s refrigerant level is one way to ensure that your AC blows cold air. Using a refrigerant gauge and adding more refrigerant if necessary will help keep your AC running smoothly during hot weather seasons.

Clean Your Condenser Coils

Turn Off the Power

If you want to make your car’s air conditioning colder, you should start by cleaning the condenser coils. First, turn off the power in your vehicle and allow it to cool down for a few minutes before attempting to clean the coils.

The condenser coils are located at the front of your vehicle, near the engine. They are responsible for releasing heat from the refrigerant so that the chilled air can be blown into your car’s cabin. Over time, dirt and debris can build up on the coils and impair their ability to effectively release heat. This can cause your AC system to work harder than necessary and reduce its cooling capacity.

Clean the Coils with a Soft Brush

Once the power is turned off, it’s time to clean the condenser coils. You will need a soft brush, such as one made of nylon or horsehair, to remove any dust, dirt, or other buildup from the coils.

Gently brush the surface of the coils to loosen any accumulated debris. Be sure to cover all areas thoroughly, paying special attention to hard-to-reach spots. Avoid using a pressure washer or high-pressure air compressor, as these can damage the coils or push dirt deeper into them.

After you have brushed the coils, use compressed air or a vacuum cleaner to remove any remaining dirt and debris. Take care not to damage the fins, which are thin metal blades arranged vertically along the coil. These fins help to dissipate heat, so they must remain intact for the condenser to function properly.

To finish up, replace the access panel covering the coils and restore power to your car’s HVAC system. You should notice an immediate improvement in the quality of your AC output, with colder air and improved efficiency.

Get Your AC System Serviced Regularly

If you want your car’s AC to perform at its best during hot summer days, then regular servicing is essential. Neglecting this can cause issues with the system that might reduce its output and efficiency. When an AC unit goes without maintenance for too long, it causes dust accumulation on the evaporator coils and reduces the cooling capacity of an air conditioning system.

You can schedule a checkup twice every year – once in the spring and once in the fall – before and after the hottest months of the season. This will ensure that your AC system is working efficiently all year round.

Hire a Professional Technician

To keep your AC system functioning properly and avoid costly repairs down the line, it’s important to hire a professional technician. They have the knowledge and experience required to diagnose problems and ensure the proper installation and upkeep of your vehicle’s AC system.

A competent technician will thoroughly inspect your vehicle’s air-conditioning system, including the hoses, lines, seals, compressors, and other components. By doing so, they can spot potential issues and prevent expensive damage in the future.

Schedule Maintenance Annually

If your car’s AC is blowing warmer-than-usual air or not working correctly, one possible solution is scheduling annual maintenance checks. During these checks, technicians will replace disposable items such as filters and fluids while identifying any malfunctions or leaks for repair.

Certain elements need to be checked regularly: refrigerant gas levels, AC compressor life span, and electrical wiring connections. If small issues are not addressed promptly, they can become major problems over time, leading to more significant expenses.

Address Any Issues Promptly

If your AC develops some mechanical problem, it’s best to address the issue as soon as possible. Waiting can mean more expensive repairs or even a damaged system beyond repair.

In addition, by resolving problems early on when they are minor, you can save yourself a headache later and avoid decreased efficiency, accelerated wear and tear on parts, or costly replacement of an entire unit.

Replace Old Components

If your car’s AC isn’t cooling efficiently, old components may be the culprit. Replacing these parts could boost overall performance and help lower energy usage.

  • The compressor is one essential component responsible for circulating refrigerant throughout the system. If it fails, replacing that with a new one must be your first priority.
  • The condenser, which serves to remove heat from the compressed refrigerant and convert it back into a liquid state, should also be checked regularly for any leaks or debris buildup.
  • Other critical parts include evaporator coils, belts, and drive pulleys, blower motors/switches, thermostat, drier and expansion valve/core.
“It’s imperative vehicle owners understand how important preventive maintenance is to keep their vehicles running at top performance,” said Rich White, executive director, Car Care Council. “The benefits of good vehicle upkeep go beyond initial vehicle cost but prolong functionality and resale value.”
To summarize, keeping your car’s AC functioning reliably requires three things: regular servicing, staying alert and addressing issues promptly, and maintaining and replacing components as needed. By following these tips, you’ll improve the lifespan of your vehicle’s air-conditioning system, maximize fuel economy and stay cool in the scorching sun.

Use Reflective Sunshades

If you want to make your car AC colder, using reflective sunshades is one of the best ways to do it. By reflecting sunlight away from your car’s interior, these shades can significantly reduce heat buildup and allow your air conditioner to work more efficiently.

Install Sunshades on Windows

The most common type of sunshade is designed to be installed on your car’s windows. These shades come in a variety of sizes and styles to fit different models and years. They are usually made of reflective material like Mylar or polyethylene terephthalate (PET), which reflects up to 90% of UV rays and heat.

To install window sunshades, simply insert them between the glass and the door frame. They usually have suction cups or clips that hold them in place. You can also find custom-fitted sunshades for your rear windshield or backseat windows. When not in use, they can be folded up and stored in a small bag.

Place Sunshades on Outdoor Units

In addition to window shades, you can also use sunshades on your outdoor units. If your car has a sunroof or a large rear window, placing a shade over it can help keep the interior cooler. Some sunshades even come with magnets that attach to the body of the car, so you don’t have to worry about them blowing away while driving.

You can also purchase exterior coverings specifically designed to protect your car from heat and UV rays. These include full-car covers made of reflective fabric or mesh material that allows airflow, reducing temperature buildup inside the car during hot weather.

Choose Light-Colored Sunshades

The color of your sunshades can also affect their ability to reflect heat and reduce temperature. Generally, light-colored shades work better than dark ones because they absorb less sunlight and reflect more of it away from the car. Shades that are silver or white in color tend to be the most effective.

If you are looking for a stylish option, some sunshades come in patterns or designs that match your car’s interior or exterior color scheme. Just be sure to choose a shade that still has reflective properties if you want to see maximum cooling benefits.
