Car Condenser Problems & Diagnosis
There are more than heat exchangers in a car A/C system, and that includes the condenser. Modern automotive condensers are usually constructed from aluminum, whilst earlier versions were built using brass or copper. These units look similar to radiators, but feature a slimmer construction. It is also constructed as a series of tubes that are surrounded by fins. They depend on air flowing through them, and that’s why they are located in front of the radiator.
The Role of a Car Condenser
An evaporator is designed to absorb heat. A condenser is designed to release heat. They release heat that is absorbed by refrigerant, while flowing through the evaporator. It works similarly to how radiators release heat from engine coolant, which is flowing through the engine. When the refrigerant enters the condenser in the form of a high-pressure vapor, it gradually turns back into a cooler high-pressure liquid. Simply put, it flows through the condenser and cools.
Now that you have a better understanding on how condensers work, let’s check out the common car condenser problems and how they can be diagnosed:
A noticeable leak normally indicates there is some sort of condenser failure. Some of the causes of condenser leaks include physical damage or age. When it leaks, depending on the severity or the location of the leak, the remaining amount of high-pressured refrigerant will eventually leak out. This has negative consequences as it disables the entire A/C system. Since the condenser unit is a single piece of equipment, it needs to be replaced as a whole when a leak occurs.
When you experience significant reduced cooling, it could mean that your A/C condenser is failing or has failed. Oftentimes, the entire cooling system will work less efficiently if refrigerant flow is restricted. This can happen when the condenser is damaged in one way or another. If the refrigerant does not flow freely, the system will be unable to produce as much cool air as it usually can.
How Often must a Car Condenser be Maintained?
A car’s A/C condenser, evaporator, and other related components require maintenance on a regular basis. You see, the entire system uses several pounds of refrigerant continually cool air that has been pulled through the air conditioner lines. Over time, the refrigerant canister will sit empty. When it does, it will require a recharge to start working properly again.
If the lines get damaged, refrigerant is allowed to escape. This necessitates not only a full recharge, but repair of the system as well. A trained technician can complete the task by hooking the lines up to a tank that is designed to refill the canister to ideal pressure ratings.
Is your car’s A/C condenser not working up to your expectations? It is recommended that you get it checked by a professional technician. They can help you best decide whether to replace your A/C condenser. Remember, condensers are a critical component to the operation of your car’s A/C system!
