Summary
Operating as a licensed HVAC contractor in Miami requires comprehensive compliance with both Florida state regulations and Miami-Dade County local requirements. Contractors must obtain proper state licensing through the DBPR, which includes meeting experience requirements, passing examinations, and maintaining continuing education. Additionally, all HVAC work requires permits and inspections through the county's regulatory system. The subtropical climate and hurricane considerations make Miami's HVAC market robust but demanding, with specific requirements for equipment ratings and installation standards. Success in this market requires maintaining proper insurance coverage, bonding, and staying current with both state licensing renewals and local registration requirements while ensuring all technicians have appropriate EPA certifications for refrigerant handling.
License Requirements
HVAC contractors in Miami must obtain a state license through the Florida Department of Business and Professional Regulation (DBPR). Class A contractors can work on unlimited capacity systems, while Class B contractors are limited to systems under 25 tons. Requirements include: 4 years of experience or relevant education, passing the state exam covering HVAC theory, codes, and business/finance, and maintaining continuing education (14 hours every 2 years). Miami-Dade County requires additional local registration. License renewal occurs every 2 years with fees around $138-$189 depending on classification.
Permit Requirements
All HVAC installations, replacements, and major repairs require permits through Miami-Dade County's Regulatory and Economic Resources Department. Commercial projects may also need City of Miami permits. Applications require detailed plans, load calculations, and equipment specifications. Typical fees range from $100-$500 for residential systems and $200-$2,000+ for commercial projects. Processing time is typically 5-10 business days for standard residential permits, longer for complex commercial systems. Final inspections are mandatory before system activation.

Florida requires minimum $300,000 general liability insurance for HVAC contractors. Workers' compensation insurance is mandatory for businesses with 4+ employees (recommended for smaller operations). Miami-Dade County may require additional coverage for public projects. Many clients require $1M+ liability coverage. Contractors must also post a surety bond ranging from $5,000-$50,000 depending on license classification. Proof of insurance must be current and filed with the state and local authorities.
