What causes Freon to leak from the evaporator coil?
This is the most common spot. The freon is mostly a superheated gas while in the evaporator coil and can therefore leak from smaller holes. Freon is part gas and part liquid, depending on where the chemical is in the process and in the system. When freon leaks as a liquid, this often occurs outside.
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 much does it cost to repair a freon leak?
In many cases, the most permanent repair solution is to replace the entire evaporator coil instead of trying to weld the pinholes throughout the system. Welding a small leak can cost several hundreds of dollars, and most of the time, more leaks will show up later; costing more money in the long run.
What should I do if my AC evaporator coil is leaking?
It all depends on your warranty. If the coil is still under warranty, replacing just the coil might be the best course of action. However, when the coil is out of warranty, you might have to pay several hundred dollars for a new one – and that doesn’t even include labor.
What to do if your HVAC has a freon leak?
Larger freon leaks will most likely need to be soldered or even replace the evaporator or condenser coils. If your system loses all the freon do to a larger leak it will need to be evacuated to remove any moisture and none condensibles from the system. This is done by putting a vacuum pump on the system that sucks all the contaminant’s out.
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.
Is it better to repair or replace the evaporator coil?
And once you have a refrigerant leak, it’s usually more cost effective to completely replace the coil or entire unit than to repair the leak and recharge the unit with more refrigerant (especially if your AC takes R-22 refrigerant). Replace the entire AC unit or just the evaporator coil?
Can a freon compressor be used to seal a leak?
The compressor will them suck the sealant into the system and seal any small leaks though out the entire system. This product when used according to the instructions on the can is safe for your system with most types of freons and can be very effective.
What do I risk if I Don’t Fix my leaking evaporator core?
What do I risk if I don’t fix my leaking evaporator core on my 2004 Jeep GC? The shop just tested my non-working AC, and recharged the freon – so, for now, it’s working. Cost $118 all in. However, they tell me I have a leak in my evaporator core, and that it will take 16 hours to repair, at an estimated cost of $1800.
How can you tell if an evaporator coil is leaking?
Evaporator coils are large components that reside in dark places and are characterized by tiny dips, curves, crevices, and hard-to-see, hard-to-reach areas. When it comes to finding leaks, the needle-in-a-haystack analogy applies. And keep in mind that you might be dealing with several little leaks, not just one big obvious one.

What does a leak in the evaporator coil do?
Also known as the evaporator core, this component helps regulate AC temperature by cycling refrigerant through the system–essentially converting warm air to cool air with the help of the engine’s blower fan and compressor. A leak in the evaporator coil disrupts this process and eventually causes the system to fail.
How much does it cost to repair a freon core?
Cost $118 all in. However, they tell me I have a leak in my evaporator core, and that it will take 16 hours to repair, at an estimated cost of $1800. (I’m in NYC, labor costs are pretty high.) He also said that my current freon charge might last me the rest of the summer.
How do you replace the evaporator core in a car?
Replacing the evaporator or heater core in these cars is a MAJOR job… My ’99 information indicates that it is all done under the hood. To test the core in the vehicle you need to discharge and recover refrigerant, disconnect the core and pull a vacuum on it. To replace it you need to split the housing under the hood.
