Weather Impact
Key Biscayne’s subtropical climate presents unique challenges for HVAC & AC systems:
- High Humidity: The intense humidity requires systems with robust dehumidification capabilities to prevent mold growth and maintain comfortable indoor air quality. Look for units with features specifically designed to combat humidity.
- Intense Sun: The strong Florida sun increases the cooling load on your home. Properly sized and insulated systems are essential for efficient operation.
- Salt Air: The corrosive salt air accelerates the deterioration of HVAC components. Investing in systems with “Seacoast Protection” is crucial for longevity and reliability.
- 2026 SEER2 Standards: With Florida’s rising energy costs, upgrading to a SEER2-compliant unit can save you hundreds of dollars monthly. It’s an investment that pays for itself over time.

FAQ
- How do I choose the right size AC unit for my home?
A properly sized AC unit is crucial for efficiency. A contractor will perform a “Manual J” load calculation to determine the appropriate BTU (British Thermal Units) rating based on your home’s square footage, insulation, window type, and other factors. Avoid oversizing, as it can lead to short cycling and poor dehumidification.
- How important is energy efficiency (SEER2 rating)?
Very important, especially in Florida. Higher SEER2 ratings translate to lower energy bills. While a more efficient unit may have a higher upfront cost, the long-term savings can be significant. Consider your budget and the expected lifespan of the unit when making your decision.
- How do I verify the contractor’s license?
Always verify that your HVAC contractor is properly licensed by the Florida Department of Business and Professional Regulation (DBPR). You can verify their license at Florida DBPR (Department of Business and Professional Regulation). Hiring an unlicensed contractor can lead to shoddy workmanship and potential legal issues.
