What Should Be Considered When Replacing a Rooftop HVAC Unit in Florida?

Florida commercial rooftop HVAC systems operate under demanding environmental conditions.

Replacement equipment should therefore be evaluated according to both building requirements and local climate conditions.

Important Florida RTU Considerations

• High outdoor design temperature
• High humidity
• Long annual cooling season
• Fresh-air latent load
• Coastal salt exposure
• Coil and cabinet corrosion protection
• Existing roof curb
• Supply and return duct openings
• Roof structural conditions
• Wind and anchoring requirements
• Electrical compatibility
• Local permitting and installation requirements

For coastal projects, enhanced corrosion protection may include protective coil coatings, corrosion-resistant hardware or upgraded cabinet materials depending on project requirements.
