What comp costs per hvac technician in Mississippi

The Bureau of Labor Statistics counts 2,700 heating, air conditioning, and refrigeration mechanics and installers on payrolls in Mississippi (May 2025), the 37th largest workforce among the 50 states and DC. The median wage is $23.41 an hour, 20% below the US median of $29.33.

Heating, air conditioning, and refrigeration mechanics and installers make up about the same share of Mississippi jobs as they do nationally (location quotient 0.88).

At the US median of $2.74 per $100 of payroll (Mississippi does not publish its figure online), comp on one worker at that wage costs about $0.64 for every hour worked, or $1,334 a year full time. A 2-person crew comes to roughly $2,668 a year in premium before any experience mod.

Because premium is charged on payroll, who you hire moves the bill. Mississippi pay runs from $17.39 an hour at the 10th percentile to $36.65 at the 90th, so the same rate costs $0.48 an hour on a new hire and $1.00 on a senior hand.

Workers comp requirements in Mississippi

  • Coverage required: 5+ employees; no construction carve-out
  • Owners and sole proprietors: Owners excluded by default; may elect in at a statutory assumed wage
  • State fund: Private market (no state fund)
  • Waiting period: 5 days; retroactive if disability lasts more than 14 days

Mississippi is one of the few states with no construction carve-out, so a one-to-four-employee construction firm is not required to carry coverage.

If your crews work across the line, list those states under item 3.A or 3.C of your policy before the job starts. Rates follow the state where the work is done, not where your office is.

What moves a HVAC comp bill

  • Service techs and install crews usually share one class, so the rate is driven by your claim history: back strains from lifting condensers and falls from ladders and roofs are the typical losses.
  • If you also do sheet-metal fabrication or duct work outside buildings, ask how your bureau classifies it. Some of that work rates differently from installation and service.
  • Dispatchers, office staff, and outside salespeople can be rated as clerical or sales when their duties keep them out of the field. Keep their timesheets separate.
  • Company vehicles put a lot of miles on service crews. A driving policy and clean MVRs help on the auto side and with comp, because vehicle accidents on the job are comp claims.
