Leaves, bugs, and other potential things on the road could block the airflow into the condenser, which will reduce the effectiveness of the AC. In some cases, not only the filter will be clogged but also the condenser, which is located right behind the car’s grille. It is also possible that more dust, pollen, and pollutants will get into the cabin as the filter is ineffective. Clogged FilterĪ clogged cabin filter can make itself known with several symptoms, the most obvious of which is insufficient airflow into the cabin. On average, a new AC compressor costs $100 to $200, while the labor cost fluctuates between $300 to $800 depending on the specific car. Cost To Fix An AC CompressorĪs mentioned earlier, for any type of AC repair, the system has to be handled properly, which means special tools and a relatively high labor cost will be parts of the repair equation.Īs with any type of car repair, the labor cost, as well as parts, will depend on your car model. Whatever the symptom is, you will need to replace the compressor if it does not work properly. There are also other symptoms, such as unusual noises or fluid leaks as described above. If you turn on the air conditioner and notice that there is no cool air coming into the cabin, it’s very possible that the compressor is the culprit. This means the total cost, depending on the part that must be replaced, could be anywhere from $160 to $1000 or more. The labor cost will vary depending on the part that has to be fixed.Įxpect the labor cost to be anywhere from $150 to $500. O-rings are a relatively small and cheap component, but because the whole system has to be depressurized and evacuated, the labor cost will be high.Ī pack of O-rings will cost around $10, while a compressor might go for several hundred dollars. If the O-rings are leaking, which could be the case if the car is newer, they will need to be replaced. 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. Unfortunately, almost any component of the AC might leak. If it turns out that the system is leaking in one place, it is necessary to replace the component that is leaking. This is necessary as when a leak occurs, it does so in gas form. The outside of the system is then inspected to see if any dye has escaped. When the refrigerant leaks, it can be checked by UV dye that is injected into the system. This may also happen if the AC is low on refrigerant. When the system is leaking, it will blow hot air instead. 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. It is normal for the refrigerant to leak a minimal amount (less than an ounce every year), but a more significant leak may cause trouble.
Leaks In The AC Systemsīecause of the operating pressure in the hoses and other components, everything must be tightly sealed. In the next section, the most common problems and the AC repair cost will be discussed. Air and moisture will cause many problems if they are in the system.ĭepending on the problem, the cost can vary. When filling the AC system, it must be done when there is a vacuum in the system. To comply with that law, a special recovery machine must be used.

It is important to note that a faulty AC should be fixed in a professional repair shop.īy law, no refrigerant is allowed to be released into the atmosphere. These possible reasons include a problem in one of the components or a leak in one of the many hoses. Related: How Does A Car Air Conditioning System Work? Cost To Fix A Faulty ACĪs previously mentioned, there are many possible reasons why an AC might not work properly. The heater fan blows air from outside the car through the cold evaporator, thus introducing cold air into the cabin. When the liquid reaches the expansion valve, it is cooled to become a gas again, which then goes through an evaporator. The liquid then passes through the dryer, which ensures that there is no gas present before the fluid continues to the thermal expansion valve. The hot and pressurized gas then moves into the condenser, where the gas cools and changes into a liquid form. Inside the compressor, several pistons compress the air, resulting in heat and high pressure. This process requires the help of a few components.Īt the start of the process, the AC compressor is connected to the engine’s crankshaft by a belt. Before we jump into the reasons why an AC might stop working, understanding the process of cooling your cabin will give you a better chance of finding the root cause of the problem.Īn air conditioning system works by changing the refrigerant from a gas to a liquid state.
