HVAC Overhead Considerations
HVAC contractors typically carry 35-50% overhead due to:
- Vehicle fleet: Service vans are expensive to purchase, outfit, and maintain
- Parts inventory: Stocking common parts ties up capital
- Technical training: EPA certifications, manufacturer training, continuing education
- Licensing: Contractor licenses, mechanical permits, insurance requirements
- Dispatching: Coordinating technicians requires office staff or software
The Service vs Install Mix
Most profitable HVAC companies balance high-margin service work with lower-margin installation volume:
| Business Model | Typical Mix | Overall Margin |
|---|---|---|
| Service-focused | 70% service / 30% install | 25-35% |
| Balanced | 50% service / 50% install | 20-28% |
| Install-focused | 30% service / 70% install | 15-22% |
Build Recurring Revenue
Maintenance agreements have the highest margins and create predictable revenue. A strong maintenance program also generates replacement leads when systems age out, converting high-margin service customers into installation sales.
