Salt Air Doesn't Stop at the Beach
If you live within 15 miles of salt water, your HVAC system faces accelerated corrosion from elevated chloride levels. Salt air doesn't stop at the beach—elevated chloride levels exist miles inland.
Warranty exclusions specifically target these installations. Equipment life is dramatically shortened.
Manufacturer Warranty Exclusions
Mitsubishi Electric warranty states:
"THIS LIMITED WARRANTY DOES NOT COVER: operating the System in a corrosive or wet environment... including sea- or salt-water"
Trane/American Standard requires:
"Indoor and outdoor coils will only be covered if a Sea Coast Kit is installed"
If you live within a few miles of the ocean and didn't pay extra for special coastal protection at time of purchase, your coil failure may not be covered at all.
Why Coastal Environments Are So Aggressive
Coastal environments combine multiple corrosion factors:
- Elevated chloride levels from salt air accelerate galvanic corrosion
- High humidity means more condensation, more electrolyte, more corrosion current
- Temperature cycles from ocean breezes create wet/dry conditions that accelerate corrosion
- Salt deposits on coils create concentrated electrolyte zones
From the Lennox Installation Manual:
"Corrosive buildup (such as salt) should be cleaned as required but no less than several times per year in coastal environments."
The CoilShield Solution
For coastal properties, CoilShield uses proven cathodic protection to help prevent coil failure. We don't replace or extend manufacturer warranty—we focus on prevention so you can avoid the cost and disruption of premature replacement.
Whether you choose our economical sacrificial anode system or our professional ICCP device, CoilShield provides continuous corrosion prevention against salt air.
Prevention Beats Replacement
Don't wait for your coil to fail in a coastal environment. Protect it now with CoilShield's proven cathodic protection technology.
