Full Cost Breakdown
| Cost Category | Low | Medium | High | Notes |
|---|---|---|---|---|
| Service Vehicle | $6,640 | $20,750 | $49,800 | 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 | $4,150 | $12,450 | $33,200 | 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 | $415 | $1,660 | $4,980 | 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 | $1,660 | $5,810 | $16,600 | 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 | $1,660 | $6,640 | $20,750 | 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 | $249 | $1,245 | $4,980 | ServiceTitan, Wintac, and FieldEdge are popular HVAC contractor platforms billed on monthly subscriptions that scale with technician seat count. |
| Marketing & Service Agreements | $830 | $4,150 | $12,450 | 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 | $249 | $664 | $1,660 | OSHA compliance is mandatory on commercial job sites. |

Businesses must register their entity with the Missouri Secretary of State and register with the Missouri Department of Revenue for sales and use tax purposes. Missouri cities and counties may require local business licenses — Kansas City, St. Louis, and Springfield each have their own licensing programs. Note that St. Louis City and St. Louis County are separate political entities with different licensing requirements.

How Missouri Compares to Neighboring States

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 Missouri — HVAC contractors face significant liability for refrigerant handling and equipment installations (filing fee: $50)
- 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 Missouri 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 Missouri 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
