- The efficiency of an AC unit is at its best for the first 10 to 12 years of its life.
- 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.
Subsequently, How long do AC coils last? For an evaporator coil to live out the fullest extent of its life, the AC unit must be regularly maintained. If proper maintenance is regularly performed, then the evaporator coils should last 10 to 15 years, which is the ideal lifetime for an evaporator coil and comparable to the lifespan of an AC unit.
Why do air conditioner coils fail? 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.
Yet, Can you repair AC coil leak? Sadly, repair isn’t an option. There’s no reliable way to repair the leaks themselves. 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.
Should I replace the evaporator coil or the entire unit? Although they are separate components they are designed to work together. If you just replace the evaporator coil, you can run into problems. A good rule of thumb is if your AC unit is over 8 years old, you should replace the entire unit.
What makes AC coils go bad?
The most common causes of evaporator coil leaks are a clogged drain line or a rusted condensation pan. The drain line can get clogged with all sorts of things, like insects, mold or dirt, which then means the water coming off the condensation coil has nowhere to go.
How do I know if my AC coil is bad?
Signs of Damaged Evaporator Coil Components
- Air coming from the vents is warm.
- Air conditioner starts and stops frequently but doesn’t properly cool your home.
- Air conditioner does not turn on.
- Refrigerant leak near the indoor cooling system components.
- Unusual noises from the cooling system, such as banging or hissing.

Certain evaporator coil cleaners can also corrode and weaken the outer lining of the coils.
How long does it take to replace AC coil?
A technician may need between three and six hours to replace your AC coil and most will charge a minimum fee. In general, you can expect labor costs of $500 to $1,000 to replace an entire AC coil.
How often do you need to clean AC coils?
In most cases, you can get away with cleaning your coils once a year with a seasonal tune-up. However, you should consider where your unit is located. If you’re in a big city with heavy air pollution, you may want to have the coils cleaned two times a year.
What causes air conditioner coils to leak?
Most commonly, evaporator coils start to leak because of corroded copper tubing. More precisely, this can happen as a result of formic acid accumulating on the evaporator coil after interacting with copper, water, and volatile organic compounds (VOCs) found in the air inside your home.
Can you fix a leaking AC coil?
Sadly, repair isn’t an option. There’s no reliable way to repair the leaks themselves. 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.
How do you tell if a coil is leaking?
If the airflow feels weak or doesn’t turn on right away, you might have a refrigerant leak. Other signs include warm air coming through the vents, hissing noises from the outdoor A/C unit, frozen evaporator coils on the outdoor unit, and unpleasant odors when you turn on the heating or cooling system.
