Quick answer
A Florida HVAC or air conditioning contractor usually needs general liability, workers' compensation, commercial auto and equipment coverage for tools and units waiting to be installed. Certified and registered air conditioning and mechanical contractors must keep at least $100,000 of public liability and $25,000 of property damage coverage (Rule 61G4-15.003), a construction business needs workers' comp from its first employee, and technicians who open refrigerant circuits need EPA certification (40 CFR 82.161).
Coverage a HVAC contractor usually needs
| Coverage | What it's for |
|---|---|
| General liability | Water damage from condensate lines and drain pans, fires from brazing or wiring, and injuries at the site, during the job or after it (completed operations). Ask about water damage limits and mold exclusions. |
| Workers' compensation | Heat illness in attics, falls from roofs and ladders, and lifting injuries. Required from the first employee in construction. |
| Commercial auto | Service vans and trucks, including units and parts on the way to a job. |
| Equipment and installation floater (inland marine) | Gauges, recovery machines, vacuum pumps and brazing kits, plus condensers, air handlers and other equipment you've bought for a job until it's installed and accepted. |
| Contractors pollution liability | Mold and refrigerant release claims, which general liability policies often exclude. |
| Umbrella or excess liability | Higher limits that commercial jobs and property managers often require. |
Florida and federal rules that apply
- To get or renew a certification or registration, an air conditioning or mechanical contractor signs an affidavit that it carries workers' compensation and public liability and property damage insurance (section 489.115(5)). Rule 61G4-15.003 sets the minimums for air conditioning, mechanical and sheet metal contractors at $100,000 of public liability and $25,000 of property damage, kept continuously.
- A construction business needs workers' compensation once it has one employee (section 440.02), and every building permit application needs a certificate of coverage or an exemption certificate (section 440.103).
- Anyone who could open the refrigerant circuit while maintaining, servicing, repairing or disposing of equipment must pass an EPA-approved certification exam: Type I for small appliances, Type II for medium-, high- and very high-pressure equipment, Type III for low-pressure equipment, or Universal for all three (40 CFR 82.161).
