The most likely reason your air-conditioner isn't cooling is the car's air-conditioner is leaking. The car's AC system needs freon to lower the ambient air temperature and creates some needed cold air. Whenever there is a freon leak on your car there is no way to cool the air.
Keep the doors and windows closed when the AC is on. Avoid opening and closing the doors frequently to prevent the cool air from escaping the room. Prevent direct sunlight from entering the room. Use curtains, blinds and shades to keep the room cool.
Recirculating air, especially on a hot day, puts less stress on your car's blower motor and air compressor, improving efficiency. Use recirculation mode to help your AC system work more efficiently to cool your vehicle down by keeping hot outside air from moving through the unit.
To fix an AC not blowing cool air, ensure the thermostat is set to "cool" mode and the temperature is set lower than the current room temperature. Inspect the air filter as a dirty filter can restrict airflow. Ensure the condenser coils are clean and free of debris. Make sure vents are open and unobstructed.
An AC leak will lead to warmer air from your vents over time. In most cases this can be fixed with a proven stop leak additive to seal up any leaks. When it's time for an AC recharge, turn to AutoZone.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
The most common causes of broken air conditioning leaks or compression issues. If you are feeling cool — but not cold — air, the issue could be a clogged filter, a problem with the cooling fan, signs of radiator trouble, or it could simply mean it's time to recharge your AC.
Increasing the AC temperature with a remote is simple. Most remotes have up and down buttons specifically for adjusting the thermostat setting. Locate the "Temp Up" button and press it repeatedly until you reach your desired warmer temperature.
Leaving your windows slightly open allows air to circulate through the car – particularly as the hot air inside rises. However, if your car is parked outdoors, we don't advise leaving more than a couple of centimetres gap between the top of the window and the door frame.
Cool mode
This is the most common and usually the default setting when you first turn on the AC. This mode sends cool air throughout your room and is great for cooling down an area after a long, hot day.
As we stated in a few sections above, it's very important to keep your air conditioner's fan on the auto setting. Some of the reasons behind this choice include: Lowered energy consumption: When your air conditioner's fan is set on auto, it will only run as needed.
During summer, start with the recirculation mode to cool down the cabin quickly. Once the desired temperature is reached, you can switch to normal mode intermittently to maintain air quality. In winter, primarily use normal mode, but you can use recirculation temporarily if the air outside is excessively cold.
Coolant leaks are probably the most common reason a car AC takes a long time to become chilly or not operate properly. A lack of coolant in the cooling system might cause it to fail. In the short term, the air conditioner will not function properly.
Just like how a low fan speed on a hot day will never make you feel cold enough, a clogged cabin air filter restricts airflow, which can make your AC seem less effective. So, while a new cabin air filter might not make your AC 'colder,' it certainly contributes to a cooler and more comfortable cabin experience.
Weak Airflow: If the air is blowing cool but feels as if it's on low or medium speed, your air conditioner either has a restriction of airflow to the blower unit, there is mold or mildew in the system, the ventilation fan is in failure, or there are broken seals near the ductwork or airbox.
