The evaporator coil is an important part of the air conditioning system. Without its help, the air conditioner will not work properly. So, the question is how long does replacing an evaporator coil take? After discussing this with the experts, we found the most accurate answer.
The process of replacing the evaporator coil can take 2-3 hours. However, the duration can be different because of accessibility and unit size. So now we know how long it will take to change the Evaporator Coil.
This article will help you to learn about the most common evaporator coil issues and how to fix them. So, let’s discuss them without wasting time.
How long does the evaporator coil last, and when it should be replaced?
Evaporator coils can last for 10-15 years if you do a regular maintenance and provide proper care. It is a perfect lifespan for an evaporator coil as compared to an AC. However, the durability of evaporator coils can be reduced because of poor maintenance.
After 15 years, your air conditioner will fail on a regular basis. If you bought your AC a few months ago and it started malfunctioning, you may have to replace it.
The outer lining of evaporator coil can get damaged because of coil cleaners. The coil can damage due to continuous use. Consequently, you have to do research to find out which cleaners are safe to use.
What is the average cost of replacing an evaporator coil?
The cost of replacing an evaporator coil depends on different factors including the AC’s brand, unit size and location. The cost can remain between $600 and $2,000. We have listed the charges below that will be applied only for device/coil replacement. The average cost of labor can be around $700.
These are the specific costs that can be charged for replacing evaporator coils based on unit size:
- The cost of two tonnes is around $550; the cost of 2.5 tonnes is around $675.
- 3 tonnes cost around $825; the cost of 3.5 tonnes is around $925.
- Four tonnes cost around $1,000; the cost of 5 tonnes is around $1,075.
Is it possible for me to replace the evaporator coil myself?
If you can replace the evaporator coil, you can do it. however, it is our recommendation that these coils should be replaced by a professional. Here are the steps for changing your evaporator coil.
- Switch off the AC
- Disconnect the
- Check the evaporator coil and remove it.
- Replace it with a new evaporator coil.
- Solder to the
- Put back the coolant.
- Close the valve
- Restart to check the air conditioner.

Problems and solutions with evaporator coils
Evaporator coils are more likely to get the following common problems and damages which specifically include leaks. Let’s read the details which include the cause and solution.
What causes the evaporator coil of an air conditioner to leak?
The most common cause of the evaporator coil leak is rusting on the copper tubing outside the coil. Corrosion is a result of formic acid accumulation in the coil because of the internal air’s mixture of water, VOCs, and copper.
How can I tell if the evaporator coil is leaking?
There are a few signs that indicate that the evaporator coil is leaking. The main 5 indicators are:
- The ventilation slots discharge warm air.
- The AC does not even turn on.
- The air conditioner cycles on and off on a frequent basis but does not cool the house properly.
- Leaks of refrigerant close to the indoor cooling system.
- Strange noises coming out of the cooling system, including a pop or a swoosh, may be heard.
Leaks can result in leakage of the central air conditioner.
Can you repair the evaporator coil leak?
Yes, you can, but the success rate is 50/50. However, the leak can be fixed temporarily by applying a sealant to the evaporator coil. The best way to fix the leaks is to replace the evaporation coil. If it is under warranty, you can use it.
What causes the evaporator coil of an air conditioner to freeze?
The most common cause of the evaporator coil to freeze is the shortage of airflow. Other common causes include a clogged air filter, a slow fan speed, and a dirty evaporator coil.
The ice of the coil becomes larger until the full loop is covered in ice. The unit may become overheated as the fan tries to draw air from the ice-stalled coil. To resolve the problem, the best bet is to contact an expert, but you can also do it yourself.
- Change it to fan-only mode to help warm air blow over the coil and boost the melting process. In order to catch melting ice and prevent flooding, prepare a bucket.
- If the filter is dirty or clogged, install a new one.
- After melting the ice from the coil, reboot the system.
In cases of repeated icing, switch off the air conditioning system. Then get help from a professional.
What is the difference between the condenser coils and evaporator coils?
Evaporator and condenser coils are different from one another. In order to cool the room air, the evaporator coil removes heat and moisture from it.
The main difference between evaporator and condenser coils is that, condenser coils take out heat and move it to the outside. The evaporator coil remains in the air handler of the refrigeration system. Additionally, the condenser coil is located behind the condenser fins.
Learn how to replace an evaporator coil yourself!
Now that you have learned about the basics of evaporator coils, it’s time to get the job done. Maintain and check your air conditioning system regularly in order to prevent coil damage.
In order to extend the life of the evaporator coil, you need to do the maintenance carefully, so take precautions. After reading this simple article, you will be able to replace your evaporator coil? You have two options whether you do it yourself or hire a professional. Think about it and make up your mind.
