Patent-pending, HVAC coil coating.

Modern & Unique Design

Coil Coating

Our corrosion-proof coil coating forms a “covalent” bond with the aluminum fin shoulder and copper tubing, re-connecting the critical tube-to-fin connection that enables maximum heat exchange. We routinely return the unit to 95% of original factory efficiency specifications.

Mobile First Approach

Exterior Cabinet Coating

Exterior cabinet coating with a ceramic radiant heat barrier, blocking 95% of the sun’s thermal load and thereby reducing external load and unit run-time and extending the life of the unit by many years.
