Why did my evaporator core fail?

The air conditioning system in your car is essential for comfort during the hot months, and the evaporator core is a critical component, without it the rest of the system will not work. 


Your evaporator core is typically inside the dashboard. Your the evaporator core circulates refrigerant, which absorbs heat from the cabin air and expels it. The refrigerant, passing through the evaporator core, changes from liquid to gas, absorbing heat from the air in the process. A fan blows air through the evaporator core's fins, cooling it before it enters the cabin, thus reducing the temperature and providing you with cold air.


The evaporator core also removes moisture from the air. As the warm, humid air passes over the cold fins, moisture condenses and is collected in a drain pan, ensuring the air in your car remains dry and comfortable. 


Your evaporator core can fail from a couple of common problems. It may develop leaks due to corrosion, physical damage, or wear and tear, leading to reduced efficiency or a total loss of cooling and/or exposure to moisture and air contaminants can corrode the evaporator core, resulting in holes and leaks that compromise its cooling ability.



Staying cool in summer is everyone's goal. If your A/C isn't working give us a call and let us take care of you.
