Our 10 Step Process

At Coastline Coating, we believe the details matter. That’s why every unit we handle goes through a thorough, hands-on process designed to ensure maximum protection, performance, and peace of mind. Here’s what you can expect when you trust us with your HVAC investment:

Step 1: We Unload the Units for You

From the very start, we take the heavy lifting off your plate—literally. Our team handles unloading so you can focus on what matters most.

Step 2: Full Disassembly With care

We don’t cut corners. Every unit is unboxed and completely disassembled by hand. We hang each piece individually, ensuring no part is overlooked and everything receives full, even treatment.

Step 3: Precision Degreasing

We start with a deep degrease of every surface to remove oils, residues, and contaminants—creating the perfect foundation for maximum coating adhesion.

Step 4: High-Powered Cleaning

Next, we power wash every component—inside and out—so your unit is spotless, clean, and ready for long-term protection.

Step 5: Thorough Drying

No moisture is left behind. Every piece is carefully dried completely to prevent trapping moisture and ensure a smooth, flawless finish.

Step 6: Interior Coating Application

This is where Infiniguard goes to work. We spray the entire interior of the unit, including coils, electrical components, panels, and the inner casing. Every surface is coated with precision, reaching every critical area for complete, lasting coverage.

Step 7: Expert Reassembly and Final Prep

We rebuild your unit from the ground up, reassembling and securing every piece with care. Then we wipe down the entire exterior with alcohol wipes, leaving a smooth, clean finish.

Step 8: Exterior Coating for Full Armor

We finish by spraying the entire exterior casing, sealing your system in a durable, hydrophobic shield that resists corrosion, UV rays, and environmental damage.

Step 9: Official Certification

We proudly attach our Infiniguard 5-Year Certification sticker, verifying that your unit has received our full professional treatment and is protected for the long haul.

Step 10: Repackaged and Ready to Roll

Finally, we rebox, plastic strap, and reload your unit into your truck or trailer. It’s protected, professionally coated, and ready for whatever the elements throw its way.
