Where Family Values Meet Industry Leading Protection


Our Product
At Coastline Coating, we apply Infiniguard, an industry-leading siloxane-based coating designed for superior HVAC protection in harsh environments. This advanced formula chemically bonds at the molecular level to metal surfaces, forming a hydrophobic and corrosion-resistant barrier. Infiniguard is engineered to withstand exposure to salt-laden air, moisture, and chemical contaminants without degrading system efficiency. The result: enhanced coil longevity, reduced maintenance costs, and optimal performance in even the most aggressive coastal conditions.
-
Our siloxane-based, inorganic coating forms a chemically bonded, non-organic barrier designed to withstand the toughest coastal elements. By sealing metal surfaces at the molecular level, it provides exceptional corrosion resistance, blocking salt, moisture, and contaminants that cause rust and degradation. Unlike traditional organic coatings, it won’t peel, crack, or break down—delivering long-term protection and performance in high-exposure environments.
-
Infiniguard improves system efficiency by reducing friction on coil surfaces, allowing for smoother, uninterrupted airflow. This increase in laminar flow optimizes heat exchange, enhancing condenser capacity and overall system performance. As a result, HVAC units experience less strain, leading to energy savings of up to 15% and prolonged equipment life.
-
Our coating provides full coverage for your HVAC system, including the inside and outside of the cabinet, tubing, and electrical components, ensuring no part of your unit is left unprotected. This advanced treatment can be applied in the field, even on existing units, and is ideal for high humidity environments. A single application preserves coils and components for the entire mechanical life of the HVAC system. Once cured, the coating is FDA certified for food preparation surfaces, offering peace of mind for systems in sensitive environments. With a dry film thickness of 0.5 mils (12.7 microns), this durable layer delivers unmatched protection against corrosion, wear, and environmental stress.
-
We stand behind the quality of our work with a 5-year warranty on all coatings. Our guarantee ensures that your HVAC system remains protected from corrosion and wear, delivering long-lasting performance. If you encounter any issues within the warranty period, we’ll take care of it—no hassle, no worries.
