The HVAC Business Opportunity
HVAC is one of the most lucrative trades to start a business in — and one of the most capital-intensive. Equipment costs are high, seasonal swings are real, and the difference between a profitable HVAC company and a struggling one usually comes down to maintenance agreements.
This template covers the numbers you actually need to know.
Section 1: Startup Costs
| Item | Low Estimate | High Estimate |
|---|---|---|
| EPA Section 608 certification | $150 | $300 |
| State HVAC contractor license | $300 | $2,000 |
| General liability + workers' comp | $3,000 | $8,000/year |
| Work van (refrigerant-capable) | $15,000 | $35,000 |
| Tools & diagnostic equipment | $5,000 | $15,000 |
| Refrigerant stock & supplies | $2,000 | $5,000 |
| Website & marketing | $1,500 | $5,000 |
| Working capital (3 months) | $10,000 | $25,000 |
| Total | $37,000 | $95,300 |
HVAC has one of the highest startup costs in the trades. The specialized tools (manifold gauges, vacuum pumps, recovery machines, combustion analyzers) and refrigerant inventory add up fast. Buy quality tools — cheap recovery machines will cost you more in time and callbacks.
Section 2: The Seasonal Cash Flow Problem (and Solution)
HVAC revenue follows a predictable pattern:
- Peak season (June–August): AC installs, emergency repairs, 60–70% of annual revenue
- Secondary peak (November–January): Heating repairs and furnace installs
- Shoulder seasons (March–May, September–October): Revenue drops 40–60%
This is the single biggest challenge for new HVAC businesses. You'll feel rich in July and broke in April.
The solution is maintenance agreements. A maintenance agreement is a recurring contract where customers pay $150–$300/year for two annual tune-ups (spring AC, fall heating) plus priority scheduling and repair discounts.Why this matters:
- Predictable monthly revenue that doesn't depend on weather
- Shoulder season work that keeps your crew busy year-round
- First access to replacement sales — when you're servicing a system, you're the first to recommend replacement
- Higher customer lifetime value — agreement customers spend 2–3x more over 5 years
Target: 50 maintenance agreements by end of year one. At $200/agreement average, that's $10,000 in predictable annual revenue. By year three, aim for 200+ agreements generating $40K+/year in baseload revenue.
Section 3: Service Pricing
Service call fee: $79–$129 (covers your trip; applied to the repair if they proceed) Common repair pricing:- Capacitor replacement: $200–$400
- Thermostat replacement: $200–$500
- Refrigerant recharge: $250–$600
- Blower motor replacement: $400–$800
- Compressor replacement: $1,500–$3,000
- Central AC system: $4,000–$8,000
- Furnace replacement: $3,000–$6,000
- Full HVAC system: $7,000–$15,000
- Mini-split (single zone): $3,000–$5,000
- Mini-split (multi-zone): $6,000–$12,000
Installs are where you make real money. A $7,000 system install with $3,000 in equipment cost gives you $4,000 in gross profit — equivalent to 10+ service calls.
Section 4: Marketing Plan
Google Business Profile + LSAs are your primary lead sources. HVAC emergencies (no AC in July, no heat in January) drive massive search volume. Budget $100–$200/week for LSAs during peak season. Home warranty company partnerships. Controversial, but effective for filling your schedule in year one. The pay is low ($75–$100/call) but the volume is high and it builds your customer base. Maintenance agreement marketing. Every service call should end with a maintenance agreement pitch. Offer first-year pricing at $149 to build your base. TradeKit's CRM tracks which customers don't have agreements and automates follow-up. Realtor and property manager relationships. Property managers need reliable HVAC techs on call. One good property management relationship can generate 5–10 calls/month.Section 5: First-Year Revenue Projections
Months 1–3 (ramp-up): 3–4 jobs/week, avg $400/job = $4,800–$6,400/month Months 4–6 (first peak season): 6–8 jobs/week, avg $600/job = $14,400–$19,200/month Months 7–9 (shoulder): 3–4 jobs/week + maintenance work = $6,000–$8,000/month Months 10–12 (heating season): 5–7 jobs/week, avg $500/job = $10,000–$14,000/month First-year gross revenue: $115,000–$165,000Net take-home: $55,000–$90,000 after expenses. The wide range depends heavily on how many installs you close versus service-only work.
Section 6: Growth Strategy
Year one: Solo operator, build your maintenance agreement base, focus on residential.
Year two: Hire a tech, add a second van. Target $250K revenue. Start light commercial.
Year three: Two crews, 200+ maintenance agreements, $400K–$500K revenue.
The HVAC companies that dominate their markets all have one thing in common: a massive maintenance agreement base. Every agreement is a relationship, a recurring revenue stream, and a future system replacement sale. Build that base from day one.
