Common Car A/C Problems And Maintenence Tips

Car AC problems can be a nightmare, especially during long journeys and hot weather. Ac's problems can cause discomfort and lots of trouble. An effective car AC system helps maintain cool and pleasant air.

Car AC keeps the environment humid-free and helps avoid any discomfort due to external weather. But a car ac often starts giving trouble if not taken care of properly. There are a lot of factors that can cause common car ac issues.

Common Car AC Problems: List Of Problems With Air Conditioners

Several factors are involved in the proper functioning of ac, and disturbance in any of them can cause the malfunctioning of car ac.

Some common car air conditioning problems are:

Leaking refrigerant

A leak in a car refrigerant can happen at any point, so pointing at an exact place needs expert skills. But the most commonplace leakage in a refrigerant is A/C unit hose connections. Accumulation of oil around these corners can also be a cause of the leak.

The price of fixing an oil leak depends on the place of leakage. You can use a sealant that is specifically designed for air conditioning units, and it is readily available at most auto parts stores.

Blocked/clogged condenser

The condenser of an air conditioner cools down the hot refrigerant after compressing. The cooling is done with the help of airflow. The air enters the car from the front side while driving.

If the condenser gets clogged due to dust or debris, it will not cool down the air conditioner, and the ac will work by overheating. This will ultimately result in the expelling of hot air.

The best way to get rid of this problem is to replace the condenser. You can also get it checked by an expert.

Broken condenser

If the condenser is not clogged, then there is a possibility that it is broken. Breakage of a condenser can be caused by puncture due to debris. If you find any breakage, then immediately get your condenser replaced.

Electrical issues

The electrical issues can be hard to detect on your own. You can seek professional help for car ac diagnosis. If an electrical issue or damaged or broken wires are not visible, but the ac keeps malfunctioning, get it inspected immediately by professionals.

Faulty cooling fans

A fault in the fan of the condenser can result in the expelling of hot air. If your condenser’s fan is not functioning properly, then it might not be able to blow cool air outside.

The fan’s issues can be caused by cracking by debris, blown fuses, or other electrical issues. Seek professional help to get it fixed.

Bad compressor

Your compressor is the key factor behind the cool and pleasant air blown out by your ac. If the car is not working, then a bad compressor can be the reason behind it.

A bad compressor can cause a lot of problems with the air conditioner. Run your A/C system on full blast for at least 15 minutes every three weeks to avoid problems. Damaged compressor due to lack of use is among car ac common problems.

Car Air Conditioning Repair: Car AC Diagnosis

The tips to fix the air conditioner in a car are mentioned above, but here are some other tips and advice that can help you ensure a longer life.

A little leakage from your cart is normal. This happens with many of the cars and R134a systems that have developed themselves in this race and reduced the leakage to almost nothing.

Running ac while it is blowing hot air is a terrible idea. This causes a lot of damage to your ac.

Always keep your car clean. Keeping the car clean and neat will help avoid any unwanted dirt or debris in your car.

Proper maintenance of your ac is necessary for proper functioning. If the damage is too much, then get it replaced with the help of a professional.

There is a misconception among Indians that using ac regularly may damage it. However, the opposite of this is true. Not using an ac regularly may damage the air conditioning system of your car. A well-running engine needs to be used daily for optimum performance.

Replace cabin air filter regularly

A clogged filter is one of the main reasons for AC-related issues in the car. The cabin air filter traps the dust particles and pollutants that come from outside in your car’s cabin. Low maintenance of cabin filters may result in its clogging with dust and contaminants, and it will start retaining moisture also. This dust retention can turn your cabin filter into a breeding ground for germs and bacteria.

The air filter of your air conditioner should be changed every year. This also depends on the type of vehicle you use and the conditions you drive in. So, ensure that you check your air filter for the car ac cooling to work smoothly.

Avoid pre-cooling your vehicle

While it might sound very blissful to start your drive with your car’s cabin being nice and cool, this is one thing you should avoid. Only turn on your car’s AC once you have turned on your ignition. Because your car's ac cooling system will work much better once the engine has turned on. Plus, you don’t end up wasting any more of your gas.

Get your AC regularly checked and maintained

Sure, your car’s AC might be working well without any major problems. But what if there are some issues that you don’t know of or miss? This is why, regular car air conditioner maintenance is a must. A professional will be able to spot the issues that might arise in the future and cause any problems in your vehicle.

Learn to use the Air conditioning system in the correct way

For proper air conditioner maintenance, learn to use the air conditioning system in a good way. Care can’t guarantee a long life of your ac if you do not operate it smartly.

Wherever you enter the car, lower down the glass and turn on the fan blower with a fresh air dial setting to allow the fresh air in your car. This will release the hot and warm air outside and will regulate the inside temperature.

After a few minutes, shut the windows and let the AC regulate the cabin’s temperature. Once the weather becomes optimal, turn the dial from fresh air to recirculating air and reduce the fan speed.

Follow proper steps when you use your car’s AC so that it can function properly. Here are a few important points that you must keep in mind when operating your car:

Shut down everything

This might not look relevant to many, but it is a very crucial step. Turning off everything in order is essential. The aircon should be turned off first then followed by the ignition. You can let the fan move after switching off the ac to ensure evaporation. This will save your car from turning into a breeding ground for bacteria. Make sure you follow the proper steps and don’t exit your car in a hurry to prevent any reduction in your car’s AC and its functioning.

Parking in shade

Regularly using ac is suitable for car AC maintenance but overusing is also bad for it. Park your car in the shade to avoid overheating the cabin. As the cabin temperature can rise quickly in the summer, parking it in shade can ensure that this does not happen.

Overheating of the car can damage the engine. Parking the car in the shade will prevent it from excessive heating and help maintain the car’s optimal temperature.

Ventilate your car

Just like parking your car in the shade, ventilating your car is also important. Leave your windows down and doors open and let the car run for a bit on idle. This will cool down the temperature of your car. Besides other car AC tips, remember proper ventilation is necessary for you and your car’s health. Intake and exhaust of the air will maintain an optimal temperature inside the vehicle.

How To Fix Car AC: Fix Air Conditioner In Car

You can fix your car's ac by using a manual or guide. You can also take the help of DIY videos on YouTube for car ac maintenance. Do not experiment with your car as if the issue is significant; get it fixed with an expert’s help or you can go for a car service.

Pay attention to other essential factors like a gas filling, blower cleaning, condenser, and Compressor for a long and healthy life of your car ac.

The condenser circulates the whole gas, and to maintain its chillness, blower cleaning and compressors are also crucial. This will not just efficiently run the car ac cooling but also contribute to the overall health of your car.
