Starting an HVAC business requires $20K-50K in initial investment for tools, a vehicle, insurance, and licensing. It's not cheap, but HVAC has some of the highest profit margins in home services when run well.

Step 1: Get Licensed and Certified

  • EPA 608 Certification (required for handling refrigerants)
  • State HVAC license (requirements vary by state - check your state licensing board)
  • Local business license and permits
  • Building a relationship with your local code inspector saves headaches later

Step 2: Insurance and Legal

  • General liability insurance ($1M minimum - typically $1,500-3,000/year)
  • Workers comp (required once you hire employees)
  • Vehicle insurance (commercial auto policy)
  • LLC or S-Corp formation (consult an accountant for tax advantages)

Step 3: Equipment and Vehicle

Essential tools for starting:

  • Manifold gauge set, recovery machine, vacuum pump
  • Multimeter, manometers, combustion analyzer
  • Hand tools, tubing cutters, flaring tools
  • Drill, impact driver, hole saw kit
  • Vehicle (used service van with ladder rack: $15K-25K)

Step 4: Set Up Operations

  • CRM: Start with Jobber ($49/month) - it handles scheduling, estimating, invoicing, and payments
  • Accounting: QuickBooks Simple Start ($30/month)
  • Phone: Business phone line (Google Voice works at $10/month to start)
  • Business cards and basic branding

Step 5: Pricing

Build a pricebook for your top 20 services. Price based on your costs, not competitors:

  • Calculate your loaded labor rate (hourly wage + taxes + insurance + overhead)
  • Add material costs
  • Target 50-60% gross margin on service work
  • Target 35-45% gross margin on installations

Step 6: Marketing (First 90 Days)

Your first 50 Google reviews are more valuable than any ad campaign.

1. Set up Google Business Profile (free)

2. Ask every customer for a Google review

3. Post completed projects weekly on GBP

4. Set up Google LSA when you have 10+ reviews

5. Start Google Ads ($500-1,000/month) when you have 20+ reviews

Step 7: Grow

Most HVAC startups reach profitability within 6-12 months with proper marketing. Reinvest profits into:

  • Additional tools and equipment
  • Your first hire (office person, not another tech)
  • Marketing budget increase
  • Vehicle upgrade or second truck

Worked Example: HVAC Startup First-Year Financials

Startup costs: tools ($8,000), vehicle ($18,000), insurance ($3,000), licensing ($500), CRM + accounting ($960/year), branding ($2,000). Total: ~$32,460. Month 1-3: 2 jobs/day × 22 days × $350 avg = $15,400/month. Expenses: $8,000/month (fuel, materials, insurance, loan payments). Net: $7,400/month. Month 4-6: 3 jobs/day × $400 avg = $26,400/month. Net: $16,400/month. Month 7-12: 4 jobs/day × $450 avg = $39,600/month. Net: $27,600/month. Year 1 total: ~$210K revenue, ~$120K net. Startup costs recovered by month 5-6.

What Not to Do

  • Don't start without your licenses. Operating unlicensed exposes you to fines, lawsuits, and criminal charges. EPA 608, state HVAC license, and local business license are non-negotiable.
  • Don't over-invest in equipment before you have customers. Start with service tools and add installation equipment as you grow. A $50,000 tool investment before your first customer is a mistake.
  • Don't skip insurance. One water damage claim from an installation gone wrong can bankrupt you without general liability coverage. $1,500-3,000/year is cheap insurance for your livelihood.
  • Don't delay getting reviews. Your first 50 Google reviews are more valuable than any ad campaign. Ask every single customer, starting with day one. Reviews compound - start early.
