What it takes to start
HVAC is license-heavy. Most areas require a state HVAC license and EPA 608 certification to handle refrigerant, and many require documented experience first. With a van, tools, and gauges, startup runs roughly $10,000 to $30,000.
Step 1: Get licensed and certified
- EPA 608 certification to legally handle refrigerant.
- Your state or local HVAC contractor license.
- The hands-on experience most licenses require before you qualify.
Step 2: Tools and van
- Gauges, recovery machine, vacuum pump, meters, and hand tools.
- A reliable van stocked with common parts.
Step 3: Price your work
Bill flat-rate per repair with a diagnostic fee, and set a clear peak-season emergency premium. Use the free calculator to ground your numbers.
