Why Did My Cars Ac Stop Working
One day youll likely find the air conditioning in your car has stopped working. Why? Well your cars A/C is subjected to a whole lot more heat, motion, and vibration than the unit in your house. Eventually even a system without a problem will lose its refrigerant through the tiny leaks that are present in all automotive A/C systems.
When Ac Accumulator Needs To Be Replaced
Your cars AC may need repair at some time. AC for car repairs consists of replacing or fixing several components. These components work together to provide cold air to the vehicles interior. One of these components is the accumulator. This is known as the receiver or drier. The accumulator is essentially a filter for the AC system. A failed accumulator can be a cause for AC repair. Without the proper function of this filter debris and other particulates can be flowing through your AC system. Here are the signs that your AC repair is caused by a failed accumulator.
Costs Across Us States How Does It Vary
The average labor rate across the country is between $75 and $130. If you live in an urban environment, you will pay more than those living in the country. However, theres also a difference in price based on the region of the United States that you live in.
Surprisingly, some of the highest rates can be in Mississippi, Montana, and Louisiana. On the other hand, you might pay rock-bottom prices if you live in Vermont, Hawaii, or New Hampshire. Its best to research whats normal for your area before you accept any quote. If it seems too low, you should be just as wary as if it were too high.

Leaks In The Ac Systems
Because of the operating pressure in the hoses and other components, everything must be tightly sealed. It is normal for the refrigerant to leak a minimal amount , but a more significant leak may cause trouble.
Leaks in the AC system happen not only due to the pressure and heat but also due to age, as the material becomes weaker with time.
When the system is leaking, it will blow hot air instead. This may also happen if the AC is low on refrigerant.
When the refrigerant leaks, it can be checked by UV dye that is injected into the system. The outside of the system is then inspected to see if any dye has escaped. This is necessary as when a leak occurs, it does so in gas form.
Cost To Fix An AC Leak
If it turns out that the system is leaking in one place, it is necessary to replace the component that is leaking. Unfortunately, almost any component of the AC might leak.
If the compressor runs with a low amount of refrigerant for an extended period, it will eventually break, and you will require a new compressor.
If the O-rings are leaking, which could be the case if the car is newer, they will need to be replaced. O-rings are a relatively small and cheap component, but the labor cost will be high because the whole system has to be depressurized and evacuated.
A pack of O-rings will cost around $10, while a compressor might go for several hundred dollars. The labor cost will vary depending on the part that has to be fixed.
Why Would You Need To Replace It
Theres a couple of reasons why you might need your AC compressor replaced. The most likely reason is usually due to the coil failing which is the most common cause that independent shop services as most do not service just the coil.
When a coil fails, your AC will not function at all. Without the ability to engage the clutch, with a failed coil, the compressor will never turn on and will not even attempt to cool down the air.
Clutch failure is not as common as coil failure. Sometimes, the clutch will wear out just from age of use as it is a wearable component. When the gap between the two clutch surfaces becomes large, the coil is unable to pull them together to lock up and engage the compressor.
It is very common at the dealership to replace both the clutch and the coil together whenever one of the two components fails.
The compressor is only replaced if it fails when being serviced at the dealership and it can fail for a couple of reasons. It could be replaced if its leaking and there are no serviceable seals.
The compressor could also be replaced if it fails internally and is no longer able to compress the refrigerant gas. Without proper compression, your AC will function very poorly or not at all.
The only other common failure that would require the compressor to be replaced is if it becomes seized. This happens when there is poor lubrication and can cause the compressor to lock up and not turn at all.

How Much Does It Cost To Repair A Cars Air Conditioner
If your car is struggling to keep you cool in the warmer weather, you need AC service. One question many drivers have is, How much does car air conditioning repair cost? The answer is more complex than it may seem, as your repair will tailor to your air conditioner troubles. Here is a look at three factors that can influence your cars air conditioning repair costs.
How Does An Ac System Work
The air conditioning system is packed with this refrigerant gas. The refrigerant used today comes in a variety of forms.
In the condenser, this gas is compressed and cooled. Its evaporator inside the dash is then given time to expand.
The refrigerant absorbs heat from the interior of the vehicle as it expands.
The vehicle cool gas is then redirected to the AC compressor and piped back under the hood, and so on.

When Summer Comes Around You Want Your Cars Air Conditioner To Work Perfectly
When summer comes around, you want your cars air conditioner to work perfectly. You want that cold air blowing in your car to keep you comfortable until you reach your destination. Depending on where in the country you live, it could become over 100 degrees Fahrenheit outside, which means it is a lot hotter inside your metal vehicle. A car AC not working is a major issue, and it requires an immediate trip to an auto parts store. When something in the AC breaks, you may wonder how much you will need to spend, and it all depends on what the exact issue is.
Installing a New AC
You may have purchased a car that did not come with an AC. It is possible the entire unit broke down, and you just need to start from scratch. In either scenario, the cost of installing a brand new AC system can cost you anywhere between $1,500 and $4,000. However, it can be even more than that depending on the year, make and model of your vehicle. The reason it costs so much is due to the fact you have to factor in both the parts and the price of labor.If so, try partsgeek for some incredible options to enhance your cars performance.
Fixing Leaks
Cleaning the AC
Evaluating the System
If you just need a mechanic to inspect the system to see how it is running, then you can expect to pay between $100 and $300. This inspection will include an examination of the connections, belts and hoses. The mechanic will end this with a fresh refill of refrigerant.

Why Is My Car Air Conditioner Not Blowing Cold Air
There are several reasons why your cars AC isnt blowing out cold air. First off, it might be due to a faulty or clogged expansion valve. This valve is required to regulate the amount of refrigerant that goes to the evaporator. So, if the expansion valve isnt working right, less freon will be able to reach the evaporator to help cool you down. Speaking of, your AC system might have some leaking hoses. Similarly, a leaky hose would allow refrigerant to leak out into the atmosphere. With less freon in the system, the air will gradually turn less cold. Last but not least, you also have to worry about either the AC compressor or its compressor clutch. The compressor moves refrigerant around while the clutch connects it to the engine. Without either one, the AC will fail to function properly.
How Is Ac Compressor Replacement Performed
- The technician recovers the refrigerant in the whole AC system, discharging any pressure
- The serpentine belt is removed from the AC compressor clutch pulley and the clutch is unplugged
- The low-side and high-side refrigerant lines are disconnected from the compressor body
- The failed compressor is unbolted and removed, and a new AC compressor fitted
- The lines are refitted and the belt and wiring put back in place
- The AC system is recharged with refrigerant according to manufacturers specifications
- The technician confirms the AC systems operation

What Causes Your Ac Compressor To Fail
The most common reason for an AC compressor to fail is the lack of lubricant. This happens when a lower than normal pressure is maintained into the system. When the AC system starts to leak, the pressure drops, which reduces the amount of oil that is in contact with critical parts. Such a condition will quickly cause the AC compressor to burn up and seize.
Too much pressure can also ruin an AC compressor but its a lot less likely. Some people mistakenly think that overpressurizing the AC system will make the AC blow colder. But when the compressor tries to start against too much pressure, it can destroy the clutch and the compressor.

9 out of 10 cars need an AC recharge, what about that 1 in 10 car? Are we just wasting our customers money on an unneeded service? Not at all. In 20 minutes we can check a lot. Does the compressor engage? If so, how much does the AC cool. It should be able to drop the air temperature about 30 degrees Fahrenheit. Are there and oil stains indicating a leak on the condenser, hoses, or compressor? If theres no reason not to, we then remove the refrigerant from the car and weigh it.
If we weigh it and find the proper amount of refrigerant in the system, put it back in the system and change tack. Were only 20 minute in and still have the bulk of an hour for electrical testing or whatever.
We start with the service because its what youll most likely end up needing. Were trying to give you a real price up front. Its pretty likely $260 is the least it will cost to have working AC. If thats too much, save your money, dont waste it on diagnosis. The actual car air conditioner repair may be much more.
Here Is A Basic Overview Of How Your Ac System Works:
- CompressorFirst, as the name suggests, your compressor compresses your freon before pumping it to the condenser.
- DryerCold air holds less water than warm air. As the air is being cooled, it can begin to produce extra moisture. From the condenser, your air enters a dryer. As the name suggests, this component dries the air to remove this excess moisture. It also contains a filter that helps catch and remove debris.
- EvaporatorThe air is then pushed to the evaporator through either an expansion valve or an orifice tube. Here, the cool air expands before being pushed into your cabin with the help of a blower fan.

Why Does An Ac Compressor Fail
Compressors are machines that run hot, making pressure half the year, and then they sit idle, not moving for half the year. That is not a recipe for a happy machine. Add in a dash of road salt and some sand and road debris each time you drive all winter, and it’s a miracle the AC compressors ever work.
Kidding aside, the AC compressor is designed to last the life of the car, but they often last less than 10 years. If you have a Honda, be sure to check with your dealer if your particular model and year is covered under an extended AC warranty program before you pay to have a mechanic fix it. There is a large campaign underway at Honda related to failed AC units.
Q How Much Does It Cost To Run An Air Conditioner For An Hour
Calculating the price of running an air conditioner can be done with a simple equation. First, find out the local kilowatt-per-hour cost. Then, find out the total amperage of the unit that will be running. Finally, make note of the power plug voltage.
Next, multiply the amps by the volts. This gives the total number of watts used. This should be divided by 1,000 to get the kilowatt-per-hour usage. Next, multiply the kilowatts used per hour by the cost per kilowatt hour.
As an example, a unit with 15 amps running through a standard power plug of 240 volts equals 3,600 total watts. This is divided by 1,000, coming out to 3.6 kilowatts used per hour. At the national average of 14.77 cents per kilowatt-hour, it costs 53.172 cents to run this AC for 1 hour.

How Does Ac Work In A Car
A cars air conditioner is built to manipulate refrigerant and convert it from gas to liquid and back again. Then, the refrigerant is sent to the evaporator as a cold gaseous substance at this point in the cycle.
Afterward, the air is released from outside over the gas, and the mixture transforms into a cool gaseous substance and is sent down to the cabin.
The whole process of cycling the refrigerant involves various components like the compressor, condenser, dryer, thermal expansion valve, etc. The process goes on until it releases water back outside the car through a series of other components like the evaporator coil, drain pipe, etc.
Typically, the compressor is responsible for compressing the air, creating high pressure and heat through its various pistons. This is further transferred to the condenser, which cools and changes the hot air into liquid.
After that, the fluid goes through the dryer, which ensures the absence of gas in the liquid as it moves to the thermal expansion valve. Here in the expansion valve, the liquid is cooled, transformed into a gaseous state, and sent through the evaporator.
The heater fan then blows fresh air from outside over the cold evaporator, thereby releasing the cold air straight into the cabin to cool the cars interior. However, a malfunction in one or more of these components can hinder this operation.
