What Is Coil Corrosion Protection?
Coil corrosion protection involves applying a specialised anti-corrosion coating to the outdoor coils (and sometimes internal components) of your air conditioner. These coils are made from metal — usually aluminium or copper — which can deteriorate when exposed to salt air, pollutants, cleaning agents, and acidic rain.
This breakdown, known as "formicary corrosion" or "pitting corrosion", compromises heat exchange efficiency and can lead to refrigerant leaks or full system failure. Protective coating acts like a barrier, stopping corrosion before it starts.
Signs Your AC May Be at Risk
If your property is located in one of the following environments, your system may be more vulnerable to coil corrosion:
- High pollution zones (e.g. near busy roads or industrial areas)
- Damp or coastal climates
- Frequent chemical exposure (e.g. near cleaning storage or laundries)
- Rooftop or exposed installations
- Areas with high mineral/salt content in the air
Our team provides property-specific assessments and will advise if coil corrosion protection in London is a wise investment for your system.

Our Corrosion Protection Process
Arcas uses high-grade protective coatings designed for HVAC applications. The process includes:
- Thorough coil cleaning to remove dirt, grease, and contamination
- Application of specialised coil coating, such as Blygold, Heresite, or Modine-approved formulas
- Curing and sealing for maximum adhesion and longevity
- Performance testing after treatment to ensure the unit is operating efficiently
This service is ideal for both new AC installations and existing units in high-risk environments.
FAQs
How long does coil corrosion protection last?
High-quality coatings typically last 3–5 years, depending on exposure and usage conditions. We recommend annual inspections.
Can I apply the coating myself?
No. These are industrial-grade, chemical-based treatments that must be applied by licensed technicians under safety-controlled conditions.
Does protection affect my system’s performance?
No. The coating is ultra-thin and specifically designed to allow optimal heat transfer while shielding the coils.
When should I apply corrosion protection?
Ideally during installation, or as part of scheduled maintenance if the system is already in place and at risk.
