How to lower these costs
- HVAC service vehicle (van) is one of the largest one-time costs ($35,000 – $60,000) — look for used or leased equipment, a smaller initial order, or a phased buildout to shrink the upfront check.
- Working capital/emergency reserve is one of the largest one-time costs ($15,000 – $40,000) — look for used or leased equipment, a smaller initial order, or a phased buildout to shrink the upfront check.
- Office lease/home office setup runs $0 – $1,500/month — negotiate the rate up front, shop multiple vendors, or delay this line item until revenue can cover it.
- General liability & workers' compensation insurance runs $200 – $800/month — negotiate the rate up front, shop multiple vendors, or delay this line item until revenue can cover it.
