Buy vs lease, vehicle selection, van setup, maintenance, GPS tracking, wraps, and truck stock management.

Buy vs Lease

Most HVAC contractors should buy. High mileage (20K–30K/year), heavy customization needs, and strong tax benefits favor ownership. Leasing makes sense only for rapid expansion when cash is tight.

FactorFavors buyingFavors leasing
Cash positionStrong reservesThin margins, need cash for operations
Annual mileage20,000–30,000+ milesUnder 15,000 miles (most leases cap at 12–15K)
CustomizationShelving, ladder racks, wrapsMinimal upfit needs (must return to original)
Tax positionStrong taxable income (Section 179)Limited taxable income
Section 179 tax advantage Vehicles over 6,000 lbs GVWR (Ford E-350, Ram ProMaster 3500, most box trucks): full purchase price deductible in the acquisition year. A $55,000 service van = $55,000 year-one deduction. Under 6,000 lbs: capped at ~$12,400–$20,400 first year. 100% bonus depreciation restored for assets placed in service after Jan 19, 2025.

Vehicle Selection (2026)

VehicleStarting MSRPMax payloadMPGBest for

Service-ready van (vehicle + upfit): $58,000–$80,000+. Prices up ~63% since pre-pandemic (ACCA). Ford Pro or Ram Commercial fleet desks: 5–7% APR for strong credit.

Van Setup & Organization

Standard HVAC upfit package: $7,500–$10,000. The 10 essentials:

  1. Modular aluminum shelving (lighter = better payload + fuel)
  2. Enclosed small-parts bins with secure drawers
  3. Bulkhead partition (safety + prevents shifting)
  4. Interior workspace for light fabrication
  5. Power inverter (avoid needing customer electricity)
  6. Deadbolt security with key-fob access
  7. LED interior lighting
  8. Dedicated filter storage compartment
  9. Pipe and wire racks with fastening systems
  10. Ladder racks (interior preferred for appearance)

Every tool has a designated spot. Most-used tools in easy-reach zones. End-of-day restock routine.

Preventive Maintenance Schedule

For every $1 spent on preventive maintenance, fleets avoid $4–$6 in unplanned repairs (OxMaint). Uncontrolled maintenance costs can erode 20–30% of operating margins.

FrequencyChecks
Daily (pre-trip)Tire pressure, fluid levels, lights, brakes, mirrors — FMCSA 49 CFR 392.7 requires daily inspection
Every 5,000–7,500 miOil change, fluid top-offs, tire rotation, belt/hose inspection
Every 15,000–20,000 miBrake inspection, transmission fluid, coolant, suspension
Every 30,000–50,000 miMajor service: brake pads/rotors, transmission, coolant flush, all belts/hoses
AnnuallyFull fluid change, battery replacement (preventive), AC service, full brake service

Schedule PM during shoulder season when trucks are less utilized. Never skip PM to keep a truck on the road.

GPS Tracking

ProviderMonthly/vehicleHardwareContract
Spytec GPS$8.95 (annual) / $14.95 (monthly)FreeNo contract
Samsara$27–$33$99–$148 + install1–3 years
Verizon Connect$20–$33Bundled3 years required

8-vehicle fleet annual cost: Spytec ~$860 vs Samsara $3,800–$5,600. Start with Spytec — lowest cost, no contract. Upgrade only when you need dash cams or advanced reporting at scale.

Vehicle Wraps

Daily impressions per wrapped vehicle: 30,000–70,000. CPM: $0.48 vs billboard $3.56. Break-even: fewer than 2 attributable jobs per year.

CoverageCost per vehicleLifespan
Door lettering + spot graphics$300–$8005–7 years
Partial wrap (25–50%)$1,000–$2,0005–7 years
Full van wrap$3,000–$5,5005–7 years

What a wrap MUST include (priority order): oversized phone number (readable from 100 feet), one service callout only ("Heating and Air"), company name, website URL, FL license number. What NOT to include: certifications, BBB logos, social handles, owner photos, QR codes, long service lists.

Use premium cast vinyl (3M IJ180 or Avery MPI 1105): 5–7 year lifespan vs 2–3 years for budget calendered.

Truck Stock Management

A properly stocked residential service truck carries $2,000–$4,000 in parts. More than $5,000 suggests overstocking. Less than $1,500 means too many parts runs.

Top companies achieve 82–92% first-time fix rates. The #1 driver is truck stock — having the right part on the truck. Improving FTFR from 70% to 85% saves roughly $200,000/year for a company running 100 calls per week.

Seasonal adjustment Pre-summer (April): increase capacitors, contactors, fan motors, refrigerant. Pre-winter (October): increase ignitors, heat exchangers, blower belts, gas valves. Failure to adjust creates summer stockouts — the #1 cause of second-trip callbacks.

Weekly truck counts (15 minutes) to reconcile what was used vs what's on hand. Quarterly dead stock review: anything on the truck for 90+ days without being used gets pulled back.
