Why is salty air bad for an AC unit?


A common question that our customers ask our technicians is “why is salty air bad for my AC unit?” The answer, put simply, is corrosion. Salty air increases the rate of corrosion. AC units in coastal environments are under constant attack by humid and salty air. Metals in salty coastal areas corrode ten times faster than metal in normal conditions. Corrosion has the biggest impact on the coils of the air conditioning unit. The constant exposure to salt causes the air conditioning coils to fail much sooner than coils located in less salty conditions. 

Replacing the coils on your AC unit can be costly. That is why it is important to take the necessary steps to ensure that your AC unit lasts as long as possible. Here are some of the things you can do to help extend the life of your AC unit in a salty environment.
