The Science That Stops Corrosion Cold

CoilShield isn't a new invention. It's a new application of technology that has protected critical infrastructure for two centuries. From Sir Humphry Davy's 1824 solution for the Royal Navy to today's $5 billion global market, cathodic protection has proven itself on trillions of dollars of infrastructure. Now it protects your HVAC coils.

Sir Humphry Davy demonstrates cathodic protection for the Royal Navy, solving copper ship hull corrosion by attaching blocks of iron that corrode instead of the valuable hull. Cathodic protection was born.

Michael Faraday establishes the electrochemical principles still used today in cathodic protection systems worldwide.

First cathodic protection systems installed on U.S. gas pipelines, preventing billions in infrastructure damage.

Legally mandated for underground fuel storage tanks, oil/gas pipelines, and marine vessels worldwide. Every new ship, every major pipeline uses cathodic protection.

CoilShield adapts proven cathodic protection technology for HVAC coil corrosion prevention—the first application to residential and commercial HVAC systems.

CoilShield launches residential and commercial protection systems using marine-grade magnesium anodes and professional ICCP technology.

Expanding distribution network and protecting thousands of HVAC systems nationwide. The same technology protecting ships and pipelines now protects your comfort.

Who Needs CoilShield Most?
)

The CoilShield Difference: Proven Protection for Every Application

Everyone with an air conditioner. But especially those in challenging environments where corrosion is accelerated: Coastal properties (within 15 miles of salt water), Pool and spa facilities (chlorine accelerates corrosion), Agricultural operations (ammonia, fertilizers), Humid climates (Houston, Miami, New Orleans—more condensation, faster corrosion), New construction (VOC off-gassing creates formicary corrosion), especially spray foam insulated homes (trapped VOCs create 2-3x faster corrosion rates), and Industrial/chemical environments. Also: Remote workers, families with elderly members or infants, businesses that can't close for repairs.

It's Not About Avoiding Warranty Claims

CoilShield isn't primarily about warranty coverage. Most residential coil failures ARE covered under warranty. CoilShield is about never needing that warranty claim in the first place. During peak summer season, a 'covered' claim still means 1-3 weeks without AC waiting for parts, scheduling, and warranty authorization—while you write a check for $850-$2,400 in labor and refrigerant. It's about never lying awake at 3 AM in a sweltering house, wondering when the technician can fit you in. Prevention is always better than replacement—even when someone else pays for the part.

200 Years of Proven Technology

CoilShield isn't a new invention—it's a new application of technology that has protected critical infrastructure for two centuries. The global cathodic protection market exceeds $5 billion annually, protecting trillions of dollars of infrastructure worldwide. Every new ship, every major pipeline, every underground tank, every water heater uses the same electrochemical principles CoilShield uses. This is proven engineering, not experimental technology.

Prevention Beats Replacement. Every Single Time.

Your air conditioning system is essential infrastructure. Not optional. Not a luxury. Essential. When your coil fails—and eventually, without protection, it will—you face significant out-of-pocket costs ($850-$2,400 even with warranty), days or weeks without cooling, and disruption to your work and family's comfort. Or you can prevent all of that. CoilShield: Because your comfort shouldn't depend on luck.
