Full Cost Breakdown
| Cost Category | Low | Medium | High | Notes |
|---|---|---|---|---|
| Service Vehicle | $9,120 | $28,500 | $68,400 | HVAC vans need dedicated refrigerant recovery equipment and unit transport capability. A properly racked-out service van is a meaningful five-figure capital purchase even when starting with a used cargo van. |
| HVAC Tools & Equipment | $5,700 | $17,100 | $45,600 | Refrigerant recovery equipment is legally required and is itself a meaningful capital purchase. Manifold gauges and vacuum pump add additional cost. Plan for a substantial four-figure tool kit out of the gate. |
| EPA 608 Certification & Licenses | $570 | $2,280 | $6,840 | EPA Section 608 certification is federally required to purchase and handle refrigerants (https://www.epa.gov/section608). State contractor licenses vary materially in fees and exam scope. |
| Insurance | $2,280 | $7,980 | $22,800 | HVAC liability covers property damage from refrigerant leaks, water damage from condensate lines, and CO incidents. Premiums scale with payroll, vehicle count, and claim history. |
| Initial Parts & Refrigerant Inventory | $2,280 | $9,120 | $28,500 | Refrigerant (R-410A, R-22, R-32) prices vary materially by SKU and current EPA phase-out status — plan a meaningful four-figure opening cylinder inventory. Carry common parts to avoid same-day supply runs. |
| Field Service Software | $342 | $1,710 | $6,840 | ServiceTitan, Wintac, and FieldEdge are popular HVAC contractor platforms billed on monthly subscriptions that scale with technician seat count. |
| Marketing & Service Agreements | $1,140 | $5,700 | $17,100 | Selling annual maintenance agreements creates predictable recurring revenue per system enrolled. Building a triple-digit agreement base in year one is a common operator goal. |
| Safety Equipment & PPE | $342 | $912 | $2,280 | OSHA compliance is mandatory on commercial job sites. |
| Total Startup Cost | $21,774 | $73,302 | $198,360 | Required costs only |

Common Mistakes to Avoid
- 1
Working without EPA 608 certification — it is federally illegal to purchase refrigerants without certification
- 2
Not building a service agreement portfolio — annual maintenance agreements compound into a meaningful recurring-revenue book over several seasons
- 3
Undercharging for after-hours emergency calls — summer AC failures are genuine emergencies and pricing should reflect the off-hours nature of the work
- 4
Not diversifying into commercial HVAC — commercial jobs are larger, less seasonal, and often more profitable
- 5
Skipping proper refrigerant recovery — illegal venting of refrigerants results in EPA penalties that compound on a per-day-per-violation basis under the Clean Air Act
Next Steps to Launch Your HVAC Business
- 1
Form your LLC in Maine — HVAC contractors face significant liability for refrigerant handling and equipment installations (filing fee: $175)
- 2
Obtain EPA Section 608 Universal certification — required by federal law to purchase and handle refrigerants (R-22, R-410A, R-32); take the exam through ESCO Group
- 3
Obtain your Maine HVAC contractor license — most states require a specialty contractor license with exam, experience, and financial documentation
- 4
Get a contractor surety bond at the face value required by your state and HVAC contractor liability insurance; premiums scale with payroll and vehicle count
- 5
Complete OSHA 10-hour construction safety training — required by commercial property managers and most new construction GCs
- 6
Open trade accounts with Ferguson HVAC, Johnstone Supply, or Maine regional HVAC distributors for equipment and parts
- 7
Register for NATE (North American Technician Excellence) certification — differentiates your technicians and is required by some manufacturer warranties
- 8
Set up service agreement software (ServiceTitan or Housecall Pro) to offer maintenance plan memberships generating recurring annual revenue
