Coating Your Commercial HVAC Coils

Commercial HVAC coils are essential components in maintaining indoor comfort, but they are also vulnerable to damage over time. Environmental factors like moisture, humidity, and airborne contaminants can lead to corrosion, which not only reduces efficiency but also increases energy costs and maintenance needs. One of the best ways to protect your investment is by applying a durable coating to your coils.

Applying a protective coating helps prevent corrosion from various sources, including salt, chemicals, and pollutants. This not only extends the life of your coil but also ensures that your system continues to operate at peak performance, even in harsh conditions.

Choosing the Right Coil Coating

There are many types of coil coatings available on the market, each with its own benefits and application methods. As industry professionals, we've tested numerous options and have found that Energy Guard USA stands out as a top choice for its reliability and performance.

Why Choose Energy Guard USA?

Energy Guard USA has proven to be one of the most effective solutions we’ve used for both custom and OEM replacement coils. Their advanced technology and commitment to quality make them a reliable partner for long-term protection. Here’s what sets them apart:

• Energy Guard's DCC formula (Dual Cure Chemistry) penetrates deeply into the coil and cures quickly, cutting down on labor and handling time.
• The coating contains 30% aluminum flakes, enhancing thermal conductivity and improving heat transfer efficiency. It also includes anti-microbial properties to prevent mold and mildew growth.
• At just 1 mil thick, the coating is extremely thin—about the thickness of a human hair—so it won’t interfere with airflow or reduce performance.
• It has passed rigorous 10,000-hour salt spray tests (ASTM B117), one of the toughest standards in the industry.
• Its high-solid, low-VOC polyurethane formulation makes it environmentally friendly and safe for use in sensitive environments.
• All applications are handled by certified technicians, ensuring a consistent and high-quality finish every time.

What’s the Cost of Coating a Coil?

The cost of coating depends on several factors, including the size and complexity of the coil. When you request a quote for a custom or OEM replacement coil, be sure to ask about adding a protective coating—it’s often more cost-effective to do so during the manufacturing process. While it's possible to apply a coating after installation, this usually involves additional fees and logistical challenges.

Do Coated Coils Last Longer?

Yes, when properly maintained, coated coils can last up to twice as long as uncoated ones. However, it's important to note that a coating doesn't prevent dirt or debris buildup. You should still clean your coil regularly, just as you would with an uncoated unit. Regular cleaning helps maintain the integrity of the coating and ensures it continues to protect against corrosion effectively.
