Why Is My Car AC Not Blowing Cold?

It’s that time of year again when the weather gets hot and sticky, and your air conditioner is working overtime.

But what happens when your AC starts to act up? Let’S find out…

Main Reasons Why Your Car AC Not Blowing Cold?

If your car’s AC isn’t blowing cold, there are a few possible reasons. 

The level of refrigerant level is low.

A car’s refrigerant level is low if there isn’t enough of the chemical compound in the system to create cool air. This can happen for many reasons, but the most common is simply a leak. Refrigerant leaks are usually pretty small and can be hard to spot, but they can cause big problems. A low refrigerant level will make your car’s air conditioner less effective, and it can also damage other parts of the system. If you think your car’s refrigerant level might be low, it’s best to take it to a mechanic and have them check it out.

Problem with your AC compressor.

One common problem is that the compressor fails to properly circulate the refrigerant. This can cause the AC to blow warm air, or even to stop working altogether. If this happens, it’s important to take your car to a mechanic for repairs as soon as possible. Otherwise, you could be in for a long, hot summer!

A faulty expansion valve

The expansion valve in a car’s AC system regulates the flow of refrigerant. When the valve is working properly, it helps to keep the system running at peak efficiency. However, a faulty expansion valve can cause many problems. One of the most common symptoms is a loss of cooling power. The refrigerant may also leak out of the system, causing the AC compressor to overheat. In severe cases, the expansion valve may even break, causing extensive damage to the AC system. Fortunately, there are a few simple ways to test for a faulty expansion valve. For example, if the AC system is not cooling as well as it used to, or if it has begun to make strange noises, it may be time to have the expansion valve checked.

A faulty evaporator core

A faulty evaporator core can cause a variety of problems in your car, from reduced airflow to bad smells. The evaporator core removes heat from the air, and if it’s not working properly, your car will feel warmer than usual. In addition, the evaporator core regulates humidity levels. So if it’s not working properly, you may notice an increase in condensation on your windows. If you suspect that your evaporator core is faulty, take your car to a mechanic to have it checked out. they’ll be able to confirm whether or not the problem is with the evaporator core and recommend the best course of action.

A dirty and clogged cabin air filter

As any car owner knows, it’s important to keep your vehicle clean and well-maintained. This not only helps it to look its best, but also ensures that it runs smoothly and efficiently. One often overlooked part of a car’s maintenance is the cabin filter. This filter helps to clean the air inside the car, removing debris, pollen, and other airborne contaminants. Over time, however, the cabin filter can become clogged with dirt and dust, reducing its effectiveness. If you notice that your car’s interior is starting to feel stuffy or that the air quality seems poorer than usual, it may be time to replace the cabin filter. Doing so is a simple and inexpensive way to ensure that you and your passengers can breathe easy on your next road trip.

Which Refrigerant Can You Use For Your Car AC?

There are a few different refrigerants that can be used in car ACs, and the type that you use will depend on a few different factors. Here are the most common ones:

The most common refrigerant is R134a, which is used in most newer cars. It’s a relatively safe and non-toxic option that works well in most climates. 

The R1234yf is the newest type of refrigerant on the market. It’s more efficient than R134a and doesn’t have any negative effects on the environment.

How Much Does It Cost To Put Refrigerant In A Car?

Putting refrigerants in a car is not a difficult task, but it does require some knowledge and the right tools. The cost of the refrigerant itself is relatively low, but you will also need to buy a recharge kit, which can cost between $30 and $50. In addition, you may need to rent or buy a recovery machine, which can add an additional $100 or more to the total cost. If you are not comfortable doing the work yourself, you can also hire a professional to do it for you. The average cost of this service is between $200 and $300. Thus, the total cost of putting refrigerant in a car can range from $130 to $550, depending on the method you choose.

How To Know If Your Car Air Conditioner Compressor Is Bad?

The compressor is responsible to circulate the refrigerant through the AC system. If it isn’t working properly, the whole system will suffer. So how can you tell if your compressor is going bad? One of the telltale signs is unusual noises coming from under the hood when you turn on the AC. If you hear a banging, rattling, or squealing noise, it’s likely that something is wrong with the compressor. Of course, the best way to know for sure is to take your car to a qualified mechanic and have them diagnose the problem. 

How Much Does It Cost To Fix The AC Of Your Car?

Most people don’t know this, but the cost of repairing your car’s air conditioner can be quite expensive.

The average cost of a new compressor is about $1,200, and the average cost of labor for installation is about $800. If you need to have your entire AC system replaced, the costs can be even higher.

Conclusion

Maintaining your car’s AC system is important for keeping you comfortable during the hot summer months. In addition to regularly checking the refrigerant level, it’s also important to be on the lookout for other potential problems. A dirty or clogged cabin air filter can make the inside of your car feel stuffy and humid, while a faulty expansion valve can cause the AC to blow warm air. If you suspect that there may be an issue with your car’s AC system, take it to a mechanic for diagnosis and repair. By taking care of your car’s AC system, you can ensure that everyone stays cool and comfortable all summer long.
