Air Conditioner Coil Repair: Understand your AC Coil
Air conditioners have two coils, the condenser coil and the evaporator coil.
The condenser coil is hosted in the outside AC unit.
When talking about just “coils,” people often refer to the evaporator coil, which is indoors. It is sometimes just referred to as the indoor coil.
The evaporator coil plays a significant role in absorbing heat and moisture from your house.
They are filled with cold refrigerant, which removes heat and transfers it to the outside coil for elimination.
Without a properly functioning evaporator coil, there will be no cool air. Besides, defective evaporator coils also mean the humidity levels in the house will be high.
What are the Signs that you Have a Faulty Air Conditioner Coil?
By the time you are here, you most likely have already noticed that there is something off with your air conditioning unit.
Here are signs that you have a broken or damaged AC coil:
- vents dispensing warm air instead of cool air even if the thermostat is in the cooling mode,
- the air conditioning system is ever running, but the house does not cool down,
- the air conditioner is not turning on or takes long to turn on,
- loud banging noise from the evaporator coil and sometimes the vents.
First, turn it off when you notice something is off with your evaporator coil. Next, call a professional HVAC company for AC coil repair.
5 of the most common problems
Here are some of the problems your AC coils will face. Watch out for these.
Your system may be functioning fairly well even if you notice these problems. This may give you the temptation to keep using the system. You, however, do not want to wait until it completely breaks down.
If you notice any of these problems, contact us at HVAC Santa Clarita to solve all your indoor AC coil issues.
The fan has stopped working.
The fan is a vital part of the cooling process. The evaporator coil cannot cool the house well with a defective fan.
If your fan is defective, you will realize it is not rotating. Or, it may move when you start your air conditioner and stop shortly after.
One primary reason behind a defective fan is too much dust accumulating on the blades. You may want to start by clearing the dust off the fan.
If this does not work, HVAC technicians may help solve the mechanical problem the system is facing.
A Frozen Coil
If you notice ice forming on your coils, it is frozen.
The good thing is that you can quickly solve this by calling an HVAC technician. There are usually several reasons behind frozen coils, and pinpointing which exactly is affecting you can be tricky.
Although we discourage you from trying to fix frozen coils, we understand that some diehard DIYers want to try fixing air conditioner before they can call a professional.
If you try fixing frozen AC coils, start by turning off the AC to let the ice thaw. This may take up to 24 hours. You can use your blow dryer to blow against the ice; this will help quicken the process. If you use a hair dryer, ensure you do not overheat your AC system.
After the ice is fully melted, go for the air filters. Clean the filters and ensure no dust remains. Then, clean the AC coil, clearing all the debris on the surface.
Top up the refrigerant and ensure all seals are tightly secured.
If the system keeps freezing even after these steps, only HVAC technicians can solve the problem.
A Dirty Coil
A dirty coil is one primary reason behind poor AC performance. When last did you clean your evaporator coils?
If it is more than a year ago, it is probably why you are facing poor performance.
Before you call your local HVAC company, you can wipe around the coil and ensure no dust and debris is lagging on top of it. This is a simple way to ensure optimal efficiency.
Note: Dirty AC coils create a thriving environment for harmful bacteria and mold. While cleaning your entire system, do not forget to thoroughly clean your AC coil.
Evaporator Coil Leak
Evaporator coils face a lot of issues. However, the major problem it faces is leaks. It would not be a wrap without looking at it.
If we’re to take a wild guess on what issue your AC coil is having, the first one would be that you have a leaky evaporator coil.
What causes evaporator coil leaks?
The first cause is the HVAC system vibration. These vibrations cause the aluminum fins to pierce holes against the copper tubing. This is typical in older air conditioning units. It, however, can happen in newer models too.
Unfortunately, the only viable solution to this is getting a coil replacement. This is because the chances of destroying the system during repairs are very high.
However, if other factors result in a leaky evaporator coil, you can quickly get repairs.
Reasons for AC Coil Failure
Having a professional HVAC technician at home only to be told that your system has AC coil failure can be a nightmare.
When you hear this from your local HVAC tech, you will definitely want to know what led to the failure.
The top reason is the wear and tear that comes with years of using your AC system. Over the years, the refrigerant liquid wears out the inner lining of the coils, weakening it. This is why you want to consider the age of your system before deciding whether to replace the AC coil.
And if you decide to replace the AC unit coil, the age will also determine whether you will replace just the coil or the entire AC unit.
Note: The average lifespan of AC units, including the evaporator and condenser coils is 15-20 years. If your cooling unit is more than 15 years old, that is most likely why you have an evaporator coil leak.
Also, if the system is over 15 years old, forget about replacing the evaporator coil. Just replace the entire air conditioner.
A simple ‘AC replacement near me” search will match you to the professionals in your locality.
Why Getting a New Air Conditioner is Better than Just a New Coil
When it is time to let go of HVAC repair and get a new coil, the dilemma of getting a new system or just the coil comes in.
Remember that your HVAC system has two coils that must match to work together. Getting an evaporator coil that does not match the condenser coil is like opening a can of worms; your system will have endless strings of problems.
If your system is old, finding a new evaporator coil that matches your old one, especially in terms of SEER rating, will be challenging.
AC Coil Repair and Replacement Cost
AC coil replacement costs many homeowners between $850 and $3000.
The price will depend on whether you are replacing the evaporator coil or the air handler.
Repairing defects can cost you approximately 1/3 the amount you would need to get a new coil.

How much is it to replace the coil on AC?
Many homeowners pay between $850 and $ 3000 to replace AC coils(1). The exact cost will depend on factors such as the coil’s size and efficiency rating.
Is it worth it to replace the AC coil?
Replacing the AC coil is always better than repairing it, especially after a recurrent leak.
However, replacing the entire air conditioning unit beats replacing just the coil.
Can You Repair AC Coil Leak?
Evaporator coil leaks can be repaired. However, during the repair process, there is a high risk of damaging the entire unit. This is why many HVAC technicians recommend that you replace a leaking AC coil rather than repair it.
How do you fix a broken AC coil?
If your AC coil doesn’t run, you want to check the following:
- AC filters and ensures they are clean,
- ensure the coils themselves are not dirty,
- there are no refrigerant leaks,
- The fan is working correctly.
Call your HVAC technician if you cannot pinpoint the issue.
Can I replace just the AC coil?
It is possible to replace just your coil. However, it can be risky as you must match it to the rest of your air conditioner. This is why many homeowners opt to buy a new system.
