Rooftop HVAC & Equipment Coatings

Rooftop HVAC & Mechanical Equipment Coatings

Rooftop HVAC cabinets and mechanical equipment live in the harshest exposure a building offers. Recoating the exterior protects the asset and extends its usable life.

Sun, rain, freeze-thaw, and standing moisture wear coatings down, steel rusts, and units age out early. We assess the equipment exterior, address existing rust and coating failure through proper surface preparation, and apply a project-appropriate direct-to-metal system.

Our approach

We may specify a direct-to-metal (DTM) epoxy for manually prepared steel, rooftop equipment, pipe supports, bolted connections, and atmospheric corrosion protection — subject to manufacturer guidance and substrate condition. This is gray-space, non-critical work: exterior and support infrastructure, not internal coils or critical systems.

What we cover

  • HVAC cabinets and housings
  • Dry cooler and chiller exteriors
  • Pipe supports, racks, and access steel
  • Platforms, curbs, and railings
  • Atmospheric corrosion protection with DTM systems

Coating systems

Project-appropriate systems, manufacturer-guided

We work with project-appropriate coating systems and may specify products such as ErgonArmor/Novocoat DTM systems where suitable, subject to manufacturer guidance, substrate condition, and project requirements.

See coating systems   Estimate a budget

  • System selection based on inspection and confirmed before work begins
  • PDS/SDS provided for the systems specified on each project
  • Environmental conditions logged during application
  • Before/after documentation and a maintenance recommendation

Common questions

Frequently asked

Do you coat the inside of units or coils?
No — we focus on equipment exteriors and support steel. Internal coil coatings are outside our current scope.
Can you work around live equipment?
We coordinate access and shutdown windows with your team; scope and exclusions are defined up front.
