Why Is My Car AC Blowing Hot Air?

Have you ever had a normal day running errands when all of a sudden, you realize your car AC is blowing hot air? That is literally the worst, especially on those humid, rainy summer or spring days in %%di_state%%. However, your car AC blowing hot air indicates that something is wrong with your Greenwich ride and you should find out why immediately. Let the experts at Jaguar Darien walk you through the most common reasons why your car AC is blowing hot air and how you can fix these issues! In the meantime, feel free to reach out to us if you have any questions. 

Reasons Why Your Car AC Is Blowing Hot Air 

There are five main reasons why your car AC is blowing hot air. Let’s find out what these reasons are and how you can resolve these issues before hitting the New Canaan roads again. 

Broken Compressor

The compressor kicks off the whole system, so if the starting component of the system is broken, then the rest of the system won’t work properly either. In other words, the compressor gets the refrigerant moving and a broken one won’t be able to do that.

How to fix it? Since it is difficult to repair a compressor as it has many moving parts, it is usually a better idea to just replace the compressor. However, after replacing the AC compressor, you can extend the life of your new compressor by using it more often. A good rule of thumb is to run it for about 15 minutes every few weeks since AC compressors commonly break down due to the lack of use. Using your AC after not using it for a while can shock the system, which causes the compressor to break down faster. 

Refrigerant Leak

The most common reason why your car AC is blowing hot air is that there is a leak in the refrigerant. When there is a leak in the system, this is the only time drivers will have to recharge the refrigerant since it is recycled over and over.

How to fix it? Stamford drivers will have a hard time identifying the leak, so it is a wise call to take it to your local shop or service center like the one at Jaguar Darien. Our service technicians can find out where the leak is and repair the damage as well as replace any parts if needed. The price range to fix a refrigerant leak depends on how severe the damage is and can be anywhere from $225 to $1600. 

If you are sure that the leak is small, you can use an AC leak sealer instead. 

Broken Condenser

Since the condenser removes heat from the refrigerant, a broken condenser will not be able to remove the heat and so your car AC will end up blowing hot air instead. Why is the condenser malfunctioning? Possibly because of a blockage in one of the inside lines by road debris.

How to fix it? Unfortunately, there is no way to repair a broken condenser, so you will have to replace a condenser when there’s a blockage. A replacement condenser can set you back anywhere from $450 to $950 depending on the make and model of your car. Our parts center can help you find the replacement parts your car needs! 

Faculty Cooling Fans

Included in the condenser is a pair of cooling fans that help get rid of the heat in the refrigerant. If the cooling fans are broken, your car will not be able to blow cool AC air out. Your cooling fans may be faulty due to multiple reasons, such as an issue in the electrical system, fuse blowing, or damage from road debris. 

How to fix it? Since the fans are a part of the condenser, you can only replace them as well. The fan replacements will cost anywhere from $300 to $500.

Electrical System Issues

Faculty cooling fans is one of the issues that can happen in the electrical system. However, there are many issues that can occur from this system, including damaged wires that prevent electricity going to the AC components that rely on it to function. If your car blowing hot AC air arises from an electrical issue, locating the exact problem will be difficult with many of the wires hidden inside the system. 

How to fix it? Because electrical systems are complicated to examine without dismantling the system, you should definitely rely on a service expert in Darien to figure out the issue.
