HVAC FAQs – Florida AC Guide
How much does AC repair cost in Florida?+
AC repair in Florida typically costs $150–$600 for common repairs like refrigerant recharge or capacitor replacement. Major repairs like compressor replacement can run $1,200–$2,500. Emergency after-hours calls add 30–50%.
How often should I service my AC in Florida?+
In Florida's climate, HVAC systems work harder than in most states. Service your AC at least twice per year — once in spring before the cooling season and once in fall. This extends system life and maintains efficiency.
What size AC unit do I need for my Florida home?+
Florida homes need approximately 1 ton of cooling per 400–500 sqft. A 1,500 sqft home typically needs a 3-ton unit. However, proper Manual J load calculations by a licensed HVAC tech are essential — oversizing causes humidity problems.
How long do AC units last in Florida heat?+
Florida AC units typically last 10–15 years due to year-round heavy use. Coastal units near saltwater can last less. Regular maintenance, clean filters, and proper sizing all extend system life significantly.
Should I repair or replace my AC unit?+
Use the 5,000 rule: multiply the repair cost by the unit's age. If the result exceeds $5,000, replacement is typically better. If your unit is 10+ years old and needs a major repair, replacement usually offers better long-term value.
What are signs my AC needs repair?+
Warning signs include: warm air from vents, weak airflow, unusual noises (banging, hissing), high humidity inside, water leaks around the unit, unusually high electric bills, and frequent cycling on and off.
What's the best AC brand for Florida humidity?+
Top brands for Florida's humidity include Carrier, Trane, Lennox, and Rheem. Look for units with variable-speed compressors and good SEER2 ratings (16+ SEER2). Two-stage and variable-speed units better manage Florida's humidity levels.
How do I find a licensed HVAC contractor in Florida?+
Verify licensure through the Florida DBPR (myfloridalicense.com). Look for contractors with Class A or B CAC (Certified Air Conditioning) licenses. Always get 3 written quotes, check insurance, and verify they pull permits.
