If you check the web for answers to “why is my car’s air conditioning blowing?” Then you’ve come to the right place.
The most common cause of an AC system blowing hot air is a lack of refrigerant, however you may also have a problem with your condenser. Other possibilities include a faulty compressor, faulty cooling fan, or a problem with your electrical system.
How To Fix My Car Ac
But first, let’s explore how exactly the AC system works for a car to help you better understand why it’s having problems.

The compressor takes in low-pressure, low-temperature refrigerant while in the gas and, as its name implies, compresses it into a high-pressure, high-temperature gas.
The condenser works like a mini radiator. It receives high temperature, high pressure gas from the compressor and emits heat from it. When this happens, the refrigerant condenses, becoming a high-pressure, low-temperature liquid.
There are also a couple of fans that blow on the condenser. This removes most of the heat from the coolant while it is in the lines.
Receiver/dryer manages removal of refrigerant moisture now in this liquid. This is done by filtering it through desiccants, which are a moisture-absorbing substance.

If you’ve ever seen a small package in a medicine bottle or a new pair of shoes, it’s really the same thing.
The reason moisture needs to be removed from the refrigerant is so it doesn’t freeze, which can clog the expansion valve. Water has a freezing point of -32 degrees, soda, on the other hand, has a freezing point as low as -200 degrees.
It is important that the expansion valve controls the amount of refrigerant that passes through the system, similar to the nozzle on a hose. As it passes through the expansion valve, it expands, reducing pressure and heat at the same time.
Some systems feature an orifice tube instead of an expansion valve. Both work, except the former can adjust the size of its opening based on the temperature in the evaporator. In this type of system, the receiver/dryer is replaced by an accumulator, which also works in a similar way.

The evaporator also functions like a radiator, with internal lines through which the refrigerant passes. While in these lines, heat is absorbed and sent, reducing it to approximately 32 degrees.
The phenomenon about soda is that, unlike water, which freezes at 32 degrees, it boils. This not only lowers the temperature, but also causes evaporation, which turns into a gas.
A fan blows over the evaporator, bringing cool air from the air conditioner into your cabin. The refrigerant then returns to the compressor as a low-temperature, low-pressure gas, which starts the process again.
Since refrigerant is recycled over and over again, the only reason you need to refill it is if there is a leak somewhere in the system. The first sign of a leak is if your AC starts blowing hot air.

Unfortunately, determining exactly where the leak is coming from can be difficult. Because? Because when it reaches a place with low pressure, such as a leak, it will revert to a gaseous state.
The first is to take it to a shop, who will find the leak and repair any damage or replace broken parts. Depending on the severity of the problem, it can cost between $225 and $1600. If the leak is coming from a broken hose, expect it to be less than if the compressor needed replacing.
The second option is to use an AC leak sealer, however, keep in mind that these products are for small leaks.
There are two types of leak seals. The first type conditions the seals, causing them to become inflamed. The second type flows into the system until it hits a leak and then forms a solid substance to help block it.

You can choose a bowl between $25-$50. Most have a spout that connects directly to the high pressure port. Regardless, be sure to follow the step-by-step product instructions.
If you remember from before, the condenser is able to remove heat from the refrigerant and then push it out. If for some reason it doesn’t work, your car’s AC will be hot.
Since the condenser is behind the front grille, it is possible that road debris has caused a blockage or has penetrated one of the inner lines.
While it is possible to remove the blockage, it is usually not the fix, meaning you will need to replace it. Replacing the condenser costs between $450 and $950, depending on the make and model of your vehicle.
How To Get The Maximum Cooling From Your Car Ac
If your AC is blowing hot air, the last thing you want is an electrical problem. Because? Because tracking where the problem is can be difficult because many of the wires are invisible without taking the system apart.
While you can fix any torn or broken wires with electrical tape, your best bet is to take it to an experienced professional.
As discussed earlier, the condenser also has a pair of cooling fans that help reduce the heat of the refrigerant while it is in-line. If they are broken or not working, the AC system will not work as expected.
There are several reasons why they can stop working, such as a blown fuse or a problem with the electrical system. They can also break from road debris due to being close to the front of the car. In this case, replacement is the only option. Expect to spend between $300-$500 to replace them.
Why Is My Ac In My Car Not Blowing Cold Air After A Recharge?
It all starts with the compressor, and as you guessed it, if it doesn’t work properly, the rest of the system won’t work either. Because? Because the compressor is what moves the refrigerant in the first place.
Why are AC compressors bad? One of the most common reasons is lack of use. Whenever you turn on your AC after a long period of inactivity, it can shock the system, which can cause it to wear out faster than usual.
Unfortunately, you’re still looking at a replacement value that’s between $500 to $700. Fortunately, you can extend the life of your AC compressor by using it more often.
Fortunately, if you’ve come to this, you should have a better idea about the cause. The longer you wait for the problem to be resolved, the more likely it is to get worse.
How To Eliminate Odor From A Car Air Conditioner: 14 Steps
Josh Barrett is a writer who hails from the great state of Alaska. While describing yourself in the third person isn’t his skill, writing about anything and everything automotive is. After more than 13 years entering the exciting world of car sales, he went on a trip around the world with his dog Teemo. The other day, I found out that my car’s air conditioner doesn’t blow cold air like it used to when I bought it. So I thought I’d write a quick article to help out any of you who might be dealing with a car air conditioner that doesn’t blow cold air after recharging.
Previously, car air conditioning systems were usually equipped only in expensive luxury tents. But for now, even the cheapest small cars are equipped with factory-standard air conditioning. If your car’s air conditioner is properly maintained and maintained regularly, you can expect it to continue to cool in the cabin when you need it.
But there are chances that the air conditioner does not blow cold air even after recharging the system. What could have gone wrong? To fully understand the possible cause of charged AC heating, it is important to understand how an air conditioning system works.
The main purpose of vehicle air conditioning is to cool or decrease the ambient air temperature. It does this by reducing the moisture content of the air, which lowers the relative humidity, so to speak. Warm air is full of moisture. Colder air dries up. The air conditioning system absorbs the air inside the cabin, removes or reduces moisture and blows cooler air through the air vents.
Common Car Ac Problems And Solutions
Everything seems simple, right? The basic principles in a typical air conditioning system are evaporation, condensation, compression and expansion. The main components of an A/C are as follows:
1. Coolant or Freon If your car’s air conditioner isn’t constantly blowing cool air, the first thing to check is the coolant level.
Refrigerant is the liquid that passes through the entire air conditioning system. It can evaporate at lower temperatures and condense to a liquid when exposed to high pressure. Your car’s A/C is a sealed system. Any loss of refrigerant can be attributed to leaks in the system. Remember that Freon does not fade – it leaks. If the air conditioner is always running low on refrigerant and constantly blowing hot air, check for leaks.
The compressor is the machine that drives the entire air conditioning system. If the compressor does not work or is low on oil, it tends to break down and cause the entire system to fail. This results in a faulty air conditioner and a hot, smoky cabin.
