Your AC is 8+ years (or older)
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.
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.
How long does it take to replace a coil in an AC unit?
How long does it take to replace an evaporator coil? It takes around 2 to 3 hours to replace an evaporator coil. This time will change depending on the ease of access to the component.
