When we talk about HVAC coil corrosion, the conversation usually goes straight to coastal environments. But what about inland locations—cities, airports, industrial zones—where airborne pollutants like NO₂ and SO₂ are attacking coils silently?I recently contributed a blog to Mitsubishi Electric’s The Hub, exploring the hidden impact of acid rain and urban pollution on HVAC coils—and how this challenge ties directly into Net Zero goals.

✅ Why NO₂ and SO₂ are quietly shortening coil lifespan
✅ How acid rain forms and why inland sites are at risk
✅ Why evidence-based data tools (like the NAEI) should drive coil protection strategies
✅ What facilities teams can do now to cut corrosion, save energy, and extend asset life

I’d love to hear your thoughts—especially if you work in FM, HVAC, or sustainability.
Are pollution-related failures something you’ve encountered in the field?
