The A/C/ evaporator, or evaporator core, works as a heat exchange within a vehicle's engine. Most vehicles only have one evaporator, but larger vehicles, such as an SUV or van, may have two. The evaporator is located inside the passenger compartment of the vehicle, often times buried deep within the instrument panel. Vehicles that have two evaporators generally have the second located towards the rear of the vehicle behind a side panel, or above the rear passenger seats. Understanding what an A/C evaporator does it crucial to knowing how and when to fix it. The A/C evaporator looks and functions similarly to a radiator. It is made of aluminum, and the main physical difference is that it is much thicker and smaller than a radiator. Evaporators consist of several internal flow paths with attached fins. Air passes freely through the fins just as it would in a radiator, but the tubes carry refrigerant instead of engine coolant. Older vehicles use Freon, or R-12 refrigerant, but after 1994, vehicles use HFC-134a, or R-134a.

The cold refrigerant enters the evaporator at the same time as warm air enters from the engine's blower fan. The refrigerant absorbs the heat from the warm air, and humidity condenses on the evaporator's cool surface. The condensation drips outside of the vehicle through tubes, and the refrigerant completes its path to the compressor. The A/C evaporator works like the heater core in the vehicle, only in reverse. Comparing the A/C Evaporator to the Heater Core The heater core in a vehicle transfers heat from the engine to the cabin, but the A/C evaporator works in a reverse manner, transferring warm air out of the vehicle, and then cooling it down and sending it back through. There are similarities in the two components, and each need a series of heating and cooling system components to work properly.

Leaks, malfunctioning system components, and many other issues can cause the A/C evaporator to stop working. A driver needs to know what to look for, and where to look when the cooling system stops working properly. The most common issue an A/C evaporator could have is a leak, but there are several reasons why a leak occurs. In most cases, a seam or weld has gone bad. Corrosion inside the evaporator causes an outside-in leak. This problem occurs when leaves or other organic material enter the evaporator case, usually through the air intake vents. gree split air conditioner wiringThe moist atmosphere within the evaporator decomposes organic material fast, and forms corrosive material that damages the evaporator.ac unit is making noise Whatever type of failure the evaporator endured, it needs to be replaced. cost to replace ac unit motor

There is no easy way, or effective way to fix the A/C evaporator. The A/C evaporator is not an expensive part, but due to the placement, it can be costly for labor fees to replace it. A leak causes the refrigerant to dissipate, and in turn, the air conditioning in the vehicle not to work. There are several steps that need taken to replace the A/C evaporator: The new A/C evaporator core should be installed in the reversal order of removal. Car owners should ensure that refrigerant is added, that the plate is installed in the right direction, and the inside wall of the joints are clean. Owners should always replace O-rings with new ones coated with refrigerant, and replace joint caps. Many reliable sellers on eBay offer heating and cooling parts for your vehicle. If your air conditioning is not working in your vehicle, replace the A/C evaporator with a new one from a reliable seller. Convenient shipping options ensure the part you order makes it to your door fast, so you can get your vehicle repaired and back on the road.

Location, price range, brand, and many other pre-defined filters for a more specific search can then filter the search results.There can be a number of reasons for an air conditioning system to blow warm instead of cold air. A slow refrigerant leak will reduce the effectiveness of your air conditioning system over time. Leaks occur most commonly at the condenser but can also happen at the evaporator, hoses or even at the compressor itself. There are a number of ways to check for an air conditioning leak: Note that most air conditioning systems normally leak some refrigerant over time. After five or six years of use it is normal for your air conditioning system to need recharging, and may not indicate a leak. The solution to an A/C leak is to find the leak and fix it by installing replacement components. This is a job best left to your mechanic. If you suspect you have a leak in your A/C system, have it inspected by your local mechanic at Kelowna Infiniti Nissan.

The A/C compressor is responsible for pressurizing the system. If there is a loud noise when you turn on your air conditioning, it may indicate an issue with your compressor. You can also open your car's hood and watch the compressor to see if it engages when you turn on the air condition. The clutch should start to spin shortly after you engage the system. If it does not, then the compressor has likely failed and will need to be replaced. Another potential reason your air conditioning system isn't working is a cogged orifice tube. This is located between the condenser in the front of the radiator, and the evaporator in the passenger compartment. If there is an obstruction in the tube then it will stop the refrigerant from reaching the evaporator, causing your system to blow warm air. There are other reasons that your air conditioning system could be malfunctioning, and electrical diagnostics may be required in some cases.
