AC Buying Guide
South Florida (2025)
Quick Answer
Buying a new AC system in South Florida? Key factors: Proper sizing (Manual J calculation), SEER 16+ for efficiency, hurricane-rated equipment, and enhanced dehumidification for Florida's climate. Budget $3,000-$8,000 for quality installation.
π Step 1: Proper AC Sizing
Getting the right size is critical in Florida's climate
Why Sizing Matters in Florida:
- β’ Oversized units: Cool quickly but don't remove humidity, causing comfort issues
- β’ Undersized units: Run constantly, wear out quickly, and can't keep up in summer
- β’ Proper sizing: Balances cooling and dehumidification for optimal comfort
Rough Sizing Guidelines:
Factors Affecting Size:
- β’ Insulation quality
- β’ Window size/type
- β’ Ceiling height
- β’ Home orientation
- β’ Number of occupants
Important: Always get a professional Manual J load calculation. Rough estimates can lead to poor comfort and higher energy bills.
β‘ Step 2: Understanding SEER Ratings
Energy efficiency ratings and what they mean for your bills
SEER 14-15
Basic Efficiency
Minimum for Florida, higher bills
SEER 16-18
