**The Rising Cost of Copper: Is It Still Worth It for HVAC Coils?**
Copper has been a vital part of human civilization since ancient times. Known for its bright red color and metallic sheen, it is a soft, malleable, and ductile metal with excellent electrical and thermal conductivity. In the world of HVAC, copper plays a crucial role in components like coils, pipes, fins, and more.
In early 2011, copper prices reached an all-time high of $4.63 per pound. Fast forward to 2024, and we’re seeing prices once again on the rise—currently hovering around $3.55 per pound and climbing. This increase has raised questions about whether copper coils are still a smart investment for HVAC systems.
So why is copper becoming so expensive? The answer lies in a combination of factors. The global economic recovery, especially in China, has driven up demand. A weaker U.S. dollar also contributes to higher prices. Plus, the ongoing impact of the pandemic has created supply chain disruptions, making copper less available and more costly.
Despite these challenges, many HVAC professionals still believe that copper coils are the better long-term choice. Here’s why:
**1. Superior Heat Transfer**
Copper conducts heat far more efficiently than aluminum. In fact, copper has about 60% better thermal conductivity than aluminum, which means your system will run more efficiently and use less energy over time.
**2. Strength and Flexibility**
Copper is both strong and easy to shape. This makes it ideal for manufacturing coils that need to be formed into precise shapes without breaking. Its flexibility allows for better expansion into fin collars, improving heat transfer performance.
**3. Easy to Repair and Recycle**
If copper tubes get damaged, they can be easily brazed and repaired. Aluminum, on the other hand, is harder to fix and often requires replacement. Plus, copper is one of the most recycled metals in the world, maintaining its quality even after multiple cycles.
**4. Resists Corrosion**
Copper is naturally resistant to corrosion, making it a great choice for HVAC coils that are exposed to harsh environments, such as coastal areas or extreme weather conditions.
**5. Natural Antimicrobial Properties**
Copper has natural antimicrobial properties that help reduce the growth of bacteria and fungi, leading to cleaner air and more efficient system performance.
At Nationwide Coils, we continue to use copper in our custom and OEM replacement coils because of its long-term value and performance. While the cost of copper may be rising, the benefits—especially in microchannel conversions—still make it the superior choice.
If you're considering replacing or upgrading your HVAC system, take the time to evaluate the long-term costs and benefits of copper versus aluminum. Sometimes, investing a little more upfront can save you money and hassle down the road.
