HVAC business plan
HVAC is the most capital-intensive and most heavily licensed business on this site. It also has the best structural economics, because maintenance agreements turn a seasonal trade into a recurring one.
Both facts should be on the first page of the plan.
Licensing comes before costs
State this specifically, not generically:
- Your state’s HVAC or mechanical contractor licence, and your status on it
- Documented experience hours required, and whether you have them
- EPA Section 608 certification — legally required to purchase or handle refrigerant, non-negotiable
- Bonding and insurance requirements in your state
- Whether you need a separate licence for gas work
Nobody experienced will read further if this section is vague.
Startup costs
| Item | Realistic cost |
|---|---|
| Van (used, serviceable) | $12,000–$28,000 |
| Gauges, recovery machine, vacuum pump, scales | $2,500–$5,000 |
| Nitrogen regulator, torch set, meters, hand tools | $2,000–$4,000 |
| Van racking and initial parts stock | $2,500–$6,000 |
| Licensing, exam, bonding, insurance | $3,000–$8,000 |
| Marketing, website, signage | $1,500–$4,000 |
| Working capital | $5,000–$10,000 |
| Total | $28,500–$65,000 |
That number is why most HVAC businesses start with a technician who already has tools and experience, rather than from nothing.
Two revenue lines, priced very differently
Service and repair. 50% to 65% gross margin. Small material content, high skill content. Fills the diary and produces the relationships.
Replacement. 28% to 40% gross margin. Equipment cost dominates, so the percentage is structurally lower — but a single job is worth twenty service calls in dollars.
The plan should show both separately. A projection that blends them into one margin figure is one you cannot manage against.
Maintenance agreements are the plan
This is the section that separates an HVAC plan from a wish.
An agreement at $220/year covering two visits does three things: it produces margin itself, it fills the shoulder seasons when you would otherwise be idle, and it generates repair and replacement work at effectively zero acquisition cost.
Set a target. “200 agreements by end of year two” is a real objective with real consequences. It is also the number that determines the business’s sale value if you ever exit.
Break-even
Fixed monthly costs for a one-van operation — van payment, insurance, licensing, software, phone, marketing — run roughly $3,000 to $5,500.
At a $310 average service ticket with 55% gross margin, that is 18 to 32 service calls a month to break even, before any replacement work. A busy summer week is 20 calls, so the business clears break-even easily in season and struggles in April — which is precisely the argument for agreements.
Seasonality
Show four quarters that look different from each other:
- Q1 (winter): heating calls, moderate volume
- Q2 (spring): the hard quarter — agreements and IAQ work carry it
- Q3 (summer): peak, overtime, replacement season
- Q4 (autumn): heating tune-ups, agreement renewals
A plan showing twelve equal months signals that the author has not run an HVAC company.
Twelve-month projections
- Months 1–3: 30 → 60 service calls/month, agreements at 10 → 40
- Months 4–8: peak season, 80–110 calls, 6–12 replacements
- Months 9–12: 60–80 calls, agreements at 120+, renewal cycle begins
Conservative year one for a one-van operation: $180,000 to $280,000 revenue, with gross margin around 45% blended across service and replacement.
What to run it on
Flat-rate pricing consistency and agreement management are the two operational requirements the plan should name.
Housecall Pro from $189/mo includes a flat-rate price book and the best recurring service plan management of the three — the direct answer to the agreement strategy above. Jobber at $49/mo plus $29 per seat is cheaper and sufficient while you are a single van. QuoteIQ at $29.99/mo includes consumer financing on every tier, which closes replacements.
Questions operators actually ask
What should an HVAC business plan include?
Licensing and EPA certification status, startup costs including the van and gauges, service versus replacement economics shown separately, a maintenance agreement strategy, seasonality planning, and 12-month projections. The agreement strategy is what distinguishes a serious plan.
How much does it cost to start an HVAC business?
$20,000 to $60,000 realistically. A van, gauges, recovery machine, vacuum pump, nitrogen and torch set, meters, and a stock of common parts. Licensing, insurance and bonding add several thousand more, and it is one of the most capital-intensive starts in home services.
What licensing do I need?
State HVAC or mechanical contractor licensing, which usually requires documented experience and an exam, plus EPA Section 608 certification to handle refrigerant. Requirements vary substantially by state and your plan should state yours specifically rather than generically.
How important are maintenance agreements?
They are the business model, not an add-on. Agreements smooth the shoulder seasons, produce repair and replacement work at low acquisition cost, and are the single biggest driver of what an HVAC company sells for. A plan without an agreement target is missing its most important number.
How do I handle seasonality?
Plan for it explicitly. Summer and winter carry the year; April and October do not. Maintenance agreements, indoor air quality work, and duct cleaning are the standard answers. A plan that shows twelve equal months is one nobody in the trade will believe.
