![]() 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. Booking takes just 2 minutes.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. However, it also helps to ensure the windows remain defogged and transparent which is a necessity when driving.Īt My Auto Shop we have hundreds of trained, MTA approved mechanics ready to get your AC Compressor Replacement completed. It can be… The AC compressor is a major component of the AC system, and therefore ensures the cabin remains cool. Is driving with a broken A/C compressor unsafe? The cost runs between $960 & $1,500 depending on the make and model of your vehicle. How much does a A/C compressor replacement cost?ĭespite being an uncommon issue it’s pretty expensive to have your AC compressor replaced. Once removed the clutch is unplugged and the refrigerant lines are disconnected from the compressor, before it can be replaced.įollowing the installation of the new compressor the mechanic will need to re-gas the refrigerant throughout the entire system and ensure that the AC is working properly. They will then remove the serpentine belt and AC compressor clutch pulley. In order to complete a AC compressor replacement the mechanic will need to first remove all of the refrigerant from the system, ensuring that the system is no longer pressurised. ![]() What happens during a A/C compressor replacement? A heavy clunk noise from the clutch when it engages.A seized AC compressor will often result in a broken serpentine belt.Failure of the AC system to produce cold air when activated.It is time to get your AC compressor looked at if you notice any of the following symptoms: How do you know when it is time to replace your A/C compressor? It’s an unlikely fix so you may never need to get an AC compressor replaced, although its much more likely to break down on vehicles over 15 years old. The refrigerant in the system can be harmful if released into the environment, and should always therefore be managed by a trained professional. The AC compressor in your vehicle is one of the cabin cooling systems major components and has the job of pressurising the refrigerant in the air conditioning system, as well as circulating the refrigerant which is necessary for the rest of the system to focus on keeping it cool.
