HVAC.Emergency calls answered, maintenance plans renewed.

Most HVAC techs go independent for the same two reasons: they're tired of the call rotation and they know their boss is making three times the gross margin off their hands. The math is real — a journeyman tech running their own service truck nets $140,000 to $260,000 in year two without a single subcontractor. The path to that number is shorter than the franchise sales reps will tell you, but it has three load-bearing decisions and a dozen smaller ones. This is the field-tested order.

Decision 1: Your license class and your state

HVAC licensing is state-by-state. Texas, Florida, and California require a state mechanical contractor license tied to journeyman hours; Arizona and Tennessee require a state-level contractor license with a financial bond; Pennsylvania and Wisconsin license at the city or county level. Before you put a magnet on a truck, look up your state at your contractor licensing board — every state's website lists the exam, the bond, and the experience minimum. EPA Section 608 universal certification is required to handle refrigerant everywhere; bring it day one.

Decision 2: Residential, light commercial, or both

Residential service has the fastest ramp because homeowners book online today and pay this afternoon. Light commercial — restaurants, small offices, retail — has higher tickets ($1,800 to $9,000) but a longer sales cycle and net-30 invoicing that strains cash flow in year one. Most new shops start residential, add one or two recurring light-commercial accounts in year two, and let the mix grow naturally from there.

Decision 3: The truck, fully outfitted

Your truck is your fixed cost. Buy the wrong one and you spend year one rearranging bins. The setup that works for residential service:

• Used 3/4-ton work van (Ford Transit, Ram ProMaster) with under 90K miles: $18,000–$32,000
• Shelving and bin organization (Adrian Steel or Ranger Design): $2,200–$4,800
• Diagnostic stack: manifold gauges, vacuum pump, micron gauge, combustion analyzer, multimeter: $2,500–$5,500
• Recovery machine + reclaim tanks: $900–$1,800
• Power tools and hand tools: $1,800–$3,500
• Starting parts inventory (capacitors, contactors, common refrigerant): $2,000–$4,500

Realistic all-in for a residential service truck: $30,000 to $52,000 used; $65,000 to $90,000 new. Most new shops go used — the depreciation on a new commercial van in year one is the worst dollar you can spend in this business.

Getting the first 30 service calls

Three channels work in 2026, in this order. First: Google Local Services Ads. The lead unit-cost is high ($85–$220 per residential call) but the leads are pre-qualified and exclusive. Run them at a $2,500 monthly cap until the calendar is reliably full. Second: a Google Business Profile with 20+ reviews seeded from your soft-open jobs. Free, but takes 60–90 days to rank in the local pack. Third: a partnership with one or two local home-inspector or real estate agents — they refer their clients' inspection-failure repairs and you pay a flat $40 per referral.

What to charge in year one

Diagnostic / service-call fee: $89–$149 depending on your metro. Hourly labor (after the diagnostic): $145–$210. Replacement and install: residential 3-ton system installs run $7,200 to $12,800 in 2026; price by the system size and the duct condition, not by the hour. Don't undercharge yourself to win volume — the lowest-priced shops are also the ones that burn out fastest.

The 12-week launch plan, condensed

1. Weeks 1–3: LLC, state contractor application (start now — exams take 4–8 weeks), insurance (general liability + commercial auto + work comp if you have a helper).
2. Weeks 4–6: Source the truck used, outfit it, set up the parts inventory.
3. Weeks 7–9: Pick the booking + dispatch software, build the Google Business Profile, set up Local Services Ads.
4. Weeks 10–12: Soft open at 60% pricing for the first 20 jobs in exchange for reviews. Switch to full pricing for client 21.

Our HVAC Toolkit packages the operational paperwork you'll need from day one — service-call estimates, maintenance agreements, replacement quotes with financing options, and the system-sizing shortcut — so you can launch without building any of it.

Every two-truck HVAC shop that scaled to ten trucks did it the same way: a maintenance plan that renews, sold to two-thirds of their service customers. The plan funds the cash flow, the visits surface replacements, and the loyalty kills the price-shopping problem. Most new shops know this and still set up their plan wrong. Below is the structure that actually compounds.

The two-visit, two-tier formula

Every plan should have exactly two visits a year — spring tune-up on the cooling system, fall tune-up on the heating system. Stop trying to invent a third visit; customers won't value it and your techs won't have time. Then offer two tiers: Standard ($179–$269 per year per system) and Premium ($299–$439 per year per system). Standard covers the two tune-ups and a small discount on repairs. Premium adds priority dispatch, no overtime fee on after-hours calls, and a small parts-and-labor warranty bump.

What goes in the visit (and what doesn't)

The visit takes 60–90 minutes. The tech checks refrigerant pressures, capacitor health, blower amperage, condensate drain, thermostat calibration, filter, and the outdoor unit. The tech does NOT do duct cleaning, coil cleaning, or anything that takes more than 15 extra minutes — those are upsells, priced separately, and offered at the visit. The visit ends with a one-page condition report, a photo of any issue, and a written quote for any recommended repair.

The three mistakes that kill renewal

First: not pre-scheduling. The day the tech finishes the spring visit, he books the fall visit. If you wait for the customer to call, half of them won't. Second: not auto-renewing payment. The plan is on the customer's card and renews 30 days before expiration unless they cancel. Manual renewal calls have a 40–55% drop-off rate; auto-renewal with email notice has a 8–12% drop-off rate. Third: pricing the plan as a discount instead of a benefit. 'Save 15% on repairs' is invisible. 'Priority dispatch, no overtime fees, two professional tune-ups, written condition report' is sellable.

How to sell it on a service call

The tech finishes the diagnostic, presents the repair quote, and then offers the maintenance plan as a way to lower the repair cost. Standard: 'I'll knock $35 off this repair if you sign up for our spring/fall plan today.' Take rate in the field is 30–45% when offered this way. Trying to sell the plan cold over the phone, without a tech on site, converts at under 5%.

The economics in year three

Most shops hit 600–900 active plans by month 24 of consistent selling. At an average of $240 per plan, that's $144,000 to $216,000 of pre-paid recurring revenue, plus an embedded conversion rate of 12–18% on system replacement quotes (because the customers trust you and you know their systems). Maintenance plans are not a side hustle — they are the moat.

The maintenance agreement template, the spring/fall visit checklist, and the condition-report form are all in our HVAC Toolkit so you can roll this out from week one.

A replacement quote that's faxed two days later, written in three pages of technical language, with one option and no financing detail, closes at 15–25%. The same job, quoted differently, closes at 55–65%. The difference is not the price. The difference is the structure. Below is the structure most independent multi-truck shops have settled on.

Rule 1: Three options, never one

Good, Better, Best. Good is a builder-grade single-stage at 14 SEER2. Better is a two-stage 16–17 SEER2. Best is a variable-speed inverter at 18–20 SEER2. The Best option is rarely chosen but it does the work of making the Better option look reasonable. Without the Best, your Better looks expensive. With it, your Better looks like the smart middle choice. Decoy effect — well-documented and ethical.

Rule 2: One page, in this order

1. Customer name and current system condition photo at top.
2. The three options as a side-by-side table — system, SEER, warranty, monthly payment.
3. What's included for all three (permits, disposal, refrigerant lines, thermostat).
4. Financing terms: 0% for 60 months on Better and Best, OR 9.99% for 120 months on all three.
5. Manufacturer rebate / utility rebate / 25C tax credit availability per option.
6. Lead-time and install date — concrete, not 'we'll call to schedule'.
7. One signature line at the bottom.

Rule 3: Quote on the truck, not from the office

The tech who diagnosed the system writes the quote in the driveway, hands the customer the iPad, and walks them through the three options before leaving. This is the single biggest close-rate lever. Customers who get a written quote in their hand the same day close at 2.5x the rate of customers who wait for a faxed PDF.

Rule 4: Financing in the doorway, not at the closing table

Apply for the financing approval BEFORE quoting the price. Most major HVAC financing partners (GreenSky, Synchrony, Service Finance) approve in 90 seconds via mobile. Walk in the door with the approved limit in your back pocket, then write the quote inside that limit. The customer never has to wonder if they can afford it.

What 'closes 60%' looks like

On 100 replacement quotes in year two, a shop using this structure typically closes 55 to 65, with an average ticket of $9,200 and a gross margin of 38–46%. The same 100 quotes written the old way close 18 to 25, with the same equipment and the same techs. The replacement quote is not paperwork. It's the highest-leverage document your shop produces.

Our HVAC Toolkit includes the three-option quote template, the financing-options sheet, and the condition-photo intake form — everything you need to run this structure tomorrow morning.
