What comp costs per hvac technician in District of Columbia
The Bureau of Labor Statistics counts 400 heating, air conditioning, and refrigeration mechanics and installers on payrolls in District of Columbia (May 2025), the 51st largest workforce among the 50 states and DC. The median wage is $40.57 an hour, 38% above the US median of $29.33.
This trade is a smaller part of the District of Columbia job market than it is nationally: heating, air conditioning, and refrigeration mechanics and installers hold 0.21 times their national share of jobs there.
At the US median of $2.74 per $100 of payroll (District of Columbia does not publish its figure online), comp on one worker at that wage costs about $1.11 for every hour worked, or $2,312 a year full time. A 2-person crew comes to roughly $4,624 a year in premium before any experience mod.
Because premium is charged on payroll, who you hire moves the bill. District of Columbia pay runs from $24.01 an hour at the 10th percentile to $52.04 at the 90th, so the same rate costs $0.66 an hour on a new hire and $1.43 on a senior hand.

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.
