When it comes to condensing coils, if the unit is not under warranty, it is often necessary to replace the entire air conditioning system. Cleaning the coil or replacing the air filter can help if either is dirty. If a window air conditioner unit is no longer under warranty and does not cool the room after cleaning the filter and coils, it is recommended to replace it. In this article, we will discuss how long these parts usually last, the signs that it's time to replace one, and how much it costs to replace the evaporator coil.The table below shows the average cost of replacing an AC capacitor unit that is not under warranty.
If your system is more than 7-8 years old and not covered by warranty, you should request a full AC system replacement quote. You may need to use a specific brand company to replace your coil out of warranty, even if it is not required. Replacing only the coil only delays the complete replacement of the system and a new coil will need to be reinstalled when you do so. If you have heard that the evaporator coil has come to an end and your central air conditioner is more than 8 years old, you should consider comparing the cost of replacing both the air conditioning unit and coil at the same time. This is because both components need to be combined for efficiency and proper operation.
Not all cities require a permit to replace the evaporator coil, as this is considered a repair rather than a system replacement. If the repair costs more than 50% of the replacement cost, replacing the condensing unit is usually the best option. An AC capacitor stores energy so that it already has some power when you turn on the AC unit. For example, Goodman uses A-Coils (pictured above) in its central air systems which are readily available, common in size and shape, and cheaper to manufacture. Since replacing an evaporator coil can be expensive, many HVAC professionals may recommend replacing the entire unit if your warranty has expired.
In most cases, you will need to purchase a replacement coil from the same brand that made your air conditioning unit.
