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 — maintenance agreements provide $150-$300/system in annual recurring revenue
- 3
Undercharging for after-hours emergency calls — summer AC failures are emergency situations justifying $150-$250/hour
- 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 fines up to $44,539/day
