Workers' comp cost for HVAC contractors in Jacksonville

HVAC businesses in Duval County

Duval County had 388 plumbing, heating and air-conditioning contractors (NAICS 238220, which the Census counts together with plumbing) establishments in 2023, employing 6,956 people, according to the Census Bureau's County Business Patterns.

That is 4.1% of the 9,351 such establishments statewide, and the seventh highest count among the nine counties that hold the ten cities in this guide series.

Annual payroll at those firms works out to about $68,103 per employee, which is the number that drives a workers' comp premium.

Narrowing to ZIP codes with a Jacksonville postal address, the same Census program lists 356 plumbing and HVAC contractor establishments in 2023.

HVAC firms make up 12.2% of the 3,171 construction establishments in Duval County.

For plumbing and HVAC contractor firms, Duval County's average pay of $68,103 sits above Hillsborough County ($67,600).

BLS wage data for May 2024 puts the median for HVAC mechanics and installers in the Jacksonville metro at $23.97 an hour across 3,150 jobs; statewide the median is $24.32.

At that metro median, one full-time worker earns about $49,860 a year, which adds roughly $1,493 of class 5537 premium.

How HVAC contractors are classified

HVAC installers and service techs fall under 5537, which covers installing, servicing and repairing heating, ventilation and air-conditioning systems, including the drivers of service vans. Ductwork fabricated in a shop can carry a different code than field installation, and a dispatcher or bookkeeper belongs in 8810. Because Florida HVAC work is year-round and peaks in summer, payroll estimates on a new policy often run low, and the gap shows up at audit.

At audit

• Summer payroll peaks are normal for HVAC; estimating the full year on a spring payroll leads to an audit bill.
• Shop sheet-metal fabrication can carry a different code than field installation, so track shop hours separately.

Permits and licensing in Jacksonville

In Jacksonville, the City of Jacksonville Building Inspection Division handles mechanical permits for HVAC change-outs and new systems. Under section 440.103 of Florida law, an HVAC business has to show proof of workers' comp or an exemption to receive a building permit.

Jacksonville and Duval County have operated as one consolidated government since 1968, so a single Building Inspection Division issues permits and runs inspections across almost the whole county. That makes Jacksonville the largest city in Florida by population and one of the largest in land area in the continental United States, and it means a crew can drive an hour between two jobs without leaving city limits. Drive time between sites is paid time, and it lands in the same class code as the work at the end of the drive.

Jacksonville's construction market spreads across a huge footprint: industrial and distribution buildings along the I-95 and I-295 corridors, port work at JAXPORT's terminals, federal work at the naval stations, new subdivisions in the St. Johns and Nassau county suburbs, and older housing stock in neighborhoods such as Riverside and Springfield. That spread means crews travel, and the payroll for drive time stays in the class code of the work. Many Jacksonville contractors also cross into Georgia, and out-of-state work needs other-states coverage on the policy. JEA, the city-owned utility, provides electric, water and sewer service across most of Duval County, so new services and utility relocations run through a single public utility. Riverfront redevelopment downtown and along the St. Johns River adds marine, park and mixed-use projects to the industrial and suburban work.

• JAXPORT and the naval stations at Mayport and Jacksonville bring port, logistics and federal construction work that often requires higher limits and waiver-of-subrogation endorsements.
• Northeast Florida gets fewer direct hurricane landfalls than South Florida, but nor'easters and tropical storms still drive coastal repair surges at the Beaches.

Common claims for HVAC contractors in Jacksonville

Jacksonville HVAC contractors handle residential change-outs across a large metro area plus commercial and industrial systems for warehouses. Salt air shortens condenser life near the coast, so replacement calls, and the lifting that comes with them, run high.

• Heat illness in attics, where summer temperatures run far above outdoor air
• Falls from ladders and through attic ceilings
• Strains from lifting condensers and air handlers
• Electrical shock during service calls
• Refrigerant burns and cuts from sheet-metal ductwork
