The evaporator coil is a critical component of the air conditioning system. The air conditioner will not function correctly without them. So, how long does replacing an evaporator coil take? We discussed with the specialists and found the most accurate answer.
It usually takes 2-3 hours to replace the evaporator coil. However, due to accessibility and unit size, the duration may vary. Let’s get started now that we know how long it will take to replace the Evaporator Coil.
This article discusses the most common evaporator coil issues and how to resolve them. Let’s proceed without any delay.
How long does the evaporator coil last, and when should it be replaced?
With regular maintenance and proper care, evaporator coils can last 10-15 years. That is the ideal lifespan for an evaporator coil comparable to that of an air conditioner. However, poor maintenance reduces the durability of evaporator coils.
After 15 years, your air conditioner will fail more frequently. If you purchased your air conditioner a few months ago and it has since stopped working, you may need to replace it.
Coil cleaners can also damage the evaporator coil’s outer lining. Continued use can cause gradual coil damage. As a result, you should research which cleaners are safe to use.

What is the average cost of replacing an evaporator coil?
The cost of replacing an evaporator coil varies depending on the AC brand, unit size, and location. Prices range between $600 and $2,000. The charges listed below are only for device/coil replacement. The average cost of labor is around $700.
The following are the specific costs for replacing evaporator coils based on unit size:
- Two tonnes cost around $550; 2.5 tonnes cost around $675.
- Three tonnes cost around $825; 3.5 tonnes cost around $925.
- 4 tonnes cost around $1,000; 5 tonnes cost around $1,075.
Is it possible for me to replace the evaporator coil myself?

Problems and Solutions with Evaporator Coils Normal problems and damages to evaporator coils include leaks. Continue reading for information on the causes, solutions, and more.
Problems and solutions with evaporator coils
Evaporator coils are prone to the following common problems and damages, such as leaks. Let’s go over the details, such as the cause and solution.
Is it possible to repair the evaporator coil leak?
Yes, it is possible, but the chances of success are 50/50. However, applying a sealant to the evaporator coil can temporarily repair the leak. Still, replacing the evaporation coil is the best option for repairing leaks. If your device is still under warranty, this is fantastic.
What causes the evaporator coil of an air conditioner to leak?
Rusting on the copper tubing outside the coil is the most common cause of evaporation coil leaks. Corrosion occurs when formic acid accumulates in the coil due to the internal air’s mixture of VOCs, water, and copper.
How can I tell if the evaporator coil is leaking?
There are a few indicators that the evaporator coil is leaking. Five obvious indicators:
- The ventilation slots emit warm air.
- The air conditioner cycles on and off frequently but does not adequately cool the house.
- The air conditioner does not even turn on.
- Leaks of refrigerant near the indoor cooling system.
- Strange noises from the cooling system, such as a swoosh or a pop, may be heard.
Leaks can cause the central air conditioner to leak. Read the cause of central air conditioner leaking water and know more reasons for it.
What causes the evaporator coil of an air conditioner to freeze?
The most common cause of evaporator coil freezing is a lack of airflow. A clogged air filter, a dirty evaporator coil, or a slow fan speed are common causes.
The coil’s ice grows larger until the entire loop is covered in ice. The unit may overheat as the blower fan attempts to draw air through the ice-stalled coil. It is best to consult an expert to resolve the problem, but you can do it yourself.
- Change to fan-only mode to allow warm air to blow over the coil and speed up melting. Prepare a bucket to catch melting ice and prevent flooding.
- Install a new filter if the filter is dirty or clogged.
- Once the ice has melted from the coil, restart the system.
In the event of repeated icing, turn off the air conditioning system. Then you can seek professional assistance.
What is the difference between the condenser coils and evaporator coils?
Evaporator and condenser coils are opposed. To cool the room air, the evaporator coil extracts heat and moisture from it.
The main difference between evaporator and condenser coils is that, condenser coils extract heat and transfer it to the outside. The evaporator coil is housed in the air handler of the refrigeration system. In addition, the condenser coil is positioned behind the condenser fins.
Know how to replace an evaporator coil yourself!
Now that you’ve mastered the fundamentals of evaporator coils, it’s time to get things done. Maintain and inspect your air conditioning system regularly to avoid coil damage.
Careful maintenance will also extend the life of the evaporator coil, so take precautions. After reading our simple guide, have you decided to replace your evaporator coil? You have the option of doing it yourself or hiring a professional. Think about and do things to improve your confidence.
