Why Did My Car’s AC Stop Being Cold?

Traveling in Miami’s hot weather without fully functioning auto air conditioning can be overwhelming and stressful. Additionally, not having cold air on a very hot day can be dangerous. Many people may not have a clear idea about what could be making their vehicles blow hot air. As you will learn throughout this article, different defects can affect your car’s A/C system and its ability to work correctly. Our Miami auto air conditioning repair mechanics from AAA Radiator and Auto Air Conditioning invite you to keep reading as we discuss why your car A/C stopped being cold.

How Does Your Car’s AC Work?

Many different parts play a critical role in your car’s ability to produce cold air. For many, understanding the science behind their air conditioner may be challenging. However, our Miami auto air conditioning mechanics from AAA can explain how your vehicle’s A/C system works.

The compressor – arguably the heart of your car’s A/C – is in charge of squeezing or compressing refrigerant – or coolant – into a gaseous state. After being pressurized, the refrigerant travels to the condenser, which is in charge of cooling down the refrigerant, turning it into liquid. The liquid refrigerant goes through a dryer to remove excess water and prevent liquid crystallization. After this process, the refrigerant goes to the evaporator, where fluid turns into gas, and the evaporator chills it making cold air to blow through your vehicle’s cabin.

While this is an oversimplified explanation of the auto A/C process, it helps you understand what all the different parts of your car’s A/C system are and how they help in the production of cold air.

If you feel like your car’s A/C is not cooling as it once did, our Miami auto air conditioning mechanics can help. We can take care of any issues that may be affecting the way your car’s A/C works.

Reasons Why Your Car’s AC Might Have Stopped Being Cold

Now that you have a clearer understanding of how your car’s A/C works, we can discuss the reasons why it may no longer work as it should. Most of the time, issues with your car’s A/C happens due to either a mechanical, electrical, or structural malfunction. Vehicular A/C systems – especially on newer models – are complex and made out of many different electrical and mechanical components. A simple disruption within the system can lead to a chain reaction capable of compromising your car’s ability to produce cold air any time you turn the A/C system on.

One of the most common reasons your car may have stopped producing cold air is the lack of recharge. Recharge is a process where your vehicle’s A/C system’s refrigerant is recharged to manufacturer-recommended levels. Most of the time, the loss of coolant or refrigerant happens as a result of structural deficiencies within the system, such as a cracked compressor. These kinds of issues can be resolved by taking your vehicle to an experienced Hialeah auto air conditioning repair and recharge mechanic who can help you correct any issues and recharge your car’s A/C system.

Fan motor failure is another reason why your vehicle may have stopped producing cold air. There are fan motors attached to the front side of your vehicle’s motor. It is essential for your fan or fans – if your vehicle has more than one – to work correctly at all times. Without these fans, your engine may lack proper cooling, and so would your car’s cabin.

Electrical failures can also play a significant role in your car’s inability to produce cold air. An electrical issue may prevent the different mechanical components in your car’s A/C system from activating. These issues often require proper assessment and correction. It is essential to avoid performing any electrical repairs yourself, especially if you lack the necessary training and experience. Our Miami repair shop for leaking air conditioning at AAA Radiator and Auto Air Conditioning can help.

What Should You Do if Your Car’s AC Stopped Being Cold?

Taking your car to a professional is the best thing you can do when facing issues with your vehicle’s A/C. Over our many years of experience handling auto A/C issues in Miami, we have seen cases where car owners have decided to take matters into their own hands. This DIY approach has proven to be more detrimental than beneficial in most cases. As we stated above, most auto A/C systems are made of many moving parts. Properly identifying, correcting, or replacing a faulty A/C component requires knowledge, training, experience, and skill.

Before you risk damaging your car’s A/C, it is essential to take your car to a professional auto air conditioning mechanic. Your professionally certified mechanic should be able to adequately identify and correct any issues that may have caused your car to stop producing cold air.

Many people may not have a clear idea of how they can prevent their A/C system from failing. In our experience, the best approach to solve this issue is to be proactive. There are no set dates to take your car to get Miami car repair for low powered air conditioning, and, most of the time, the most logical approach is to take your vehicle to your mechanic when there are issues. However, we recommend taking your car for a complete assessment at least twice a year. This can help you rule out any developing problems and correct any existing ones you may not have noticed.
