Corrosion of the copper tubing in the coil from the outside is the most common cause of evaporator coil leaks. This corrosion happens when formic acid accumulates on the coil as a result of the interaction of water, copper, and volatile organic compounds (VOCs) in your indoor air.

What causes a coil to rust?
Corrosion of the copper tubing in the coil from the outside is the most common cause of evaporator coil leaks. This corrosion happens when formic acid accumulates on the coil as a result of the interaction of water, copper, and volatile organic compounds (VOCs) in your indoor air.
Is it normal for an AC coil to rust?
Rust will be a normal sign of age of the coil. However, too much rust on a young coil can mean that the coil has been leaking and freezing over. As a result, the added moisture from the ice has sped up the rusting of the support parts.
Is it normal for AC coils to rust?
You'll know your HVAC coils have formicary corrosion when they develop pinhole leaks or a distinct etching on their metal surface. If you notice corrosion in your HVAC coils, call a trusted residential AC repair and replacement company like Air Products & Services promptly for the necessary solution.
Rescuing An Hvac Coil Before Rust Failure
Can the coil rot?
As the authors of an article in Reliable Plant explain, coil corrosion comes in the form of either pitting or formicary deterioration. Corrosion may occur as quickly as a few weeks after an installation or it may take up to four years to present itself.
How do you stop a coil from rusting?
The best way for a building owner to prevent coil corrosion is to apply a protective coating to the coil. Coating types include polyurethanes, epoxies, fluoropolymers and silanes. Each coating type has its own distinct advantages and disadvantages.
Is a rusty evaporator coil bad?
Corroded coils can lead to leaking refrigerant and a loss of cooling power, and they're one of the top causes of needing to have a coil replacement. Or, in some cases, replacing the whole air conditioner. Catching the problem early makes it more likely you can avoid a bigger, more costly repair.
Rusted Evaporator Coil
Is it normal for evaporator coil to rust?
Rust will be a normal sign of age of the coil. However, too much rust on a young coil can mean that the coil has been leaking and freezing over. As a result, the added moisture from the ice has sped up the rusting of the support parts.
How do I stop my AC coil from rusting?
- Have an anti-corrosive coating applied on the coils once they're clean. - Install a whole-house air cleaner on your HVAC system to capture and eliminate airborne VOCs. - Rinse down your outdoor unit with the hose every month to limit the buildup of potentially-harmful debris.
Common Causes Of Copper Evaporator Coil Failures.
Is rust normal in AC unit?
High moisture content and lack of maintenance can lead to issues such as rusting. Not only is a rusty air conditioner a cosmetic eyesore, but it can also affect your unit's functioning. A rusty HVAC may take longer to cool or heat your home, and this can result in high energy bills.
Why do AC coils corrode?
The indoor evaporator coil corrodes due to airborne volatile organic compounds (VOCs) that are off-gassed by building materials, pressed-wood furniture components, as well as textiles, fabrics, and various everyday household products.
