AHU & Drip Pan Coating

Protect the Hidden Heart of Your HVAC System

Stop Leaks Before They Start

Air handler Units (AHUs) are essential to your facility’s comfort and air quality—but because they’re often out of sight, they’re easy to overlook. At BMI Mechanical, we know that neglecting air handler maintenance can lead to corrosion and leaks that threaten critical spaces below, from operating rooms to offices and tenant apartments.

Drip pans are your first line of defense against water damage in HVAC systems. Over time, they can corrode, crack, or develop pinhole leaks. Our drip pan coatings provide a tough, waterproof seal that prevents leaks and protects your facility from costly water damaging sensitive areas below and leading to expensive repairs or disruptions.

BMI’s Non-Microbial Liquid Membrane solution

A little prevention goes a long way. BMI’s proactive approach involves applying our advanced Non-Microbial Liquid Membrane System to your air handler unit’s interior and drip pans. This seamless, waterproof coating prevents corrosion, stops leaks before they start, and extends the life of your air handling equipment—all with minimal disruption to your daily operations.
