What happens when the AC evaporator does not work?
The AC compressor will not activate. The compressor is intended to circulate refrigerant through the evaporator. It depends on maintaining a predetermined pressure to operate. As such, if there is a leak, there is reduced pressure within the system and the compressor will not activate.
What should I do if my AC evaporator is leaking?
If a leak is detected, replacement of the entire AC evaporator is the correct course of action. Some shade-tree mechanics attempt using a sealant to fix a leak, but this is always a temporary solution, and typically creates additional problems with the AC system — so we don’t recommend this type of quick-fix.
Why does my AC evaporator have a sweet smell?
You notice a strange odor when using your AC system. If your AC evaporator is leaking, a small amount of refrigerant (not coolant) will seep from the coil, core, or seals. This will produce a sweet aroma, which might get more intense when the AC is turned on.
How long does an AC evaporator coil last?
Air conditioners last anywhere from 10 to 12 years. That said, if your AC is nearing 8 years old, replacing just the evaporator coil would be like putting a brand new engine into a dying car—it’s just not worth the money.
How can I tell if my AC evaporator is damaged?
Like most AC issues, the first indicator of a damaged AC evaporator is poor performance. Since the AC evaporator is the major part that removes heat from the air, failure is rather simple to determine. However, there are 4 other warning signs of a damaged AC evaporator: 1. The cool air is weak or no cold air is blowing at all.
Why does my evaporator need to be replaced?
The main reason that an evaporator coil would fail and need to be replaced is due to erosion. Over time, the refrigerant flowing through the evaporator’s coils wears down the inner lining, making the coils weaker. Certain evaporator coil cleaners can also corrode and weaken the outer lining of the coils.

How does the evaporator work in an air conditioner?
An air conditioning system is designed to remove heat from the air. The job of the evaporator is to harness the cold refrigerant in its liquid state. As warm air passes along the evaporator coils, it collects the heat from the air and makes it cool. The cold air is then circulated through time cabin.

Why does my Lexus air conditioner have an odor?
Evaporator core from a Lexus. The most common source of odor from the heating and air conditioning is moisture accumulating on the evaporator (removed from the car, above). The evaporator is cooled by the air conditioning system, forming condensation on its fins as it operates, draining out an orifice at the bottom of it’s housing.
