Aluminum coils are very difficult to maintain and almost impossible to repair. Copper coils are the standard, and more durable, though they tend to also be more expensive. A broken condenser coil may be first noticed if the air from the AC is coming out hotter than what is indicated by the thermostat.
Condenser Coil
Copper coils use up to 3 times as much of the material as aluminum coils, making them a more expensive option. Replacing a condenser coil can cost $500 to $750.
Costs vary greatly by region (and even by zip code). To get free estimates from local contractors, please indicate yours.
