HVAC — heating, ventilation, and air-conditioning — is one of the most seasonally extreme trades, with summer cooling and winter heating demand spikes that strain working capital between peaks. Residential service shops, commercial mechanical contractors, and refrigeration specialists all use MCAs differently.
Typical advance structure.
- Advance size: $50K–$500K depending on fleet size and revenue.
- Factor: 1.27–1.40, with 1.30–1.36 most common for EPA-certified HVAC contractors with 2+ years operating.
- Term: 6–12 months daily or weekly ACH.
- Holdback equivalent: 10–17% of average daily revenue.
- Lead use of funds: equipment inventory (condensers, furnaces, mini-splits, heat pumps), service-truck fleet, technician payroll between shoulder seasons, marketing for replacement-system leads, refrigerant inventory, software (ServiceTitan).
What underwriters look for.
First, EPA Section 608 certification and any state-level mechanical license. Refrigerant handling without certification carries six-figure EPA fines.
Second, residential service versus commercial mechanical mix. Service shops with $5K–$15K average install tickets and strong replacement pipelines get tightest pricing. Commercial mechanical contractors face wider pricing because installs are $100K–$2M with long draw cycles.
Third, heat-pump and electrification revenue. Federal IRA rebates and state programs (especially New York, Massachusetts, California, Colorado) are accelerating heat-pump adoption — funders look for evidence of diversified work, not pure-play rebate dependence.
Fourth, replacement-versus-new-construction mix. Replacement work is high-margin and fast-pay; new construction is lower-margin and draw-dependent.
Fifth, financing partnerships. HVAC shops with consumer-financing partners (GreenSky, Synchrony, Service Finance) offer point-of-sale financing to homeowners — strong cash flow signal.
Common uses.
- Pre-season equipment inventory buildup (May–June for AC, September–October for furnaces, $50K–$300K).
- Service-truck fleet expansion (vans, stocked with parts, $60K–$100K per truck).
- Technician payroll during shoulder seasons (April–May, October–November).
- Heat-pump installer training and certification.
- Refrigerant inventory (R-410A phase-out, R-32 and R-454B transition, $20K–$100K).
- Marketing for replacement-system leads ($5K–$50K monthly).
What to watch out for.
Seasonality is extreme. A southern AC shop bills $300K–$800K in July and $80K–$200K in November. Daily ACH on a 1.32 factor advance taken in July creates winter cash-flow stress.
Refrigerant regulatory transitions are accelerating. R-410A is being phased out; R-32 and R-454B require new equipment and technician training. Wrong-side-of-transition inventory loses value fast.
Commercial mechanical retainage of 5–10% locks up working capital for 3–18 months.
Workers-comp claims (rooftop falls, electrical exposure, refrigerant burns) drive premium increases of 15–30% per claim cycle.
Equipment-manufacturer rebates and SPIFFs (Carrier, Trane, Lennox, Daikin) drive seasonal cash spikes that can mask underlying issues — funders look through SPIFFs to operating revenue.
State considerations.
Florida (year-round AC demand, hurricane-driven replacement spikes), Texas (extreme summer demand, fast-growing market), California (Title 24 compliance, heat-pump mandates), Arizona (extreme summer demand), New York (state-driven electrification, heat-pump rebates), Massachusetts (Mass Save heat-pump program), and Georgia (mixed climate, year-round demand) have highest volume.
APR-equivalent reality check.
A 1.32 factor over a 9-month term is roughly 65–80% APR. Compare to SBA 7(a) (11–14% APR), equipment financing for service vans (10–17% APR), and equipment-manufacturer floor-plan financing (often 0–6% APR for 60–180 days on inventory). For inventory float, manufacturer floor-plan financing is dramatically cheaper.
Common confusions.
First, "HVAC and plumbing price the same way." HVAC has more equipment-financing leverage and higher inventory carry.
Second, "Heat-pump work is recession-proof." Demand depends heavily on federal and state rebates — policy shifts can crater pipelines.
Third, "MCA is the only option for inventory buildup." Manufacturer floor-plan financing (Carrier, Trane, Lennox) often offers 90–180 day 0% financing on stocking orders.
Fourth, "SPIFFs are stable revenue." They are program-dependent and can disappear in a contract year.
Fifth, "Summer revenue covers the whole year." For southern shops it often does; for northern shops with both heating and cooling, seasonality is bimodal and shoulder months are tight.
As of 2026-06-30, Fundnode routes HVAC-contractor deals first to HVAC-specialty MCA funders, manufacturer floor-plan financing for inventory, equipment financing for service vehicles, and SBA 7(a) for established shops with strong replacement-installation pipelines.

- MCA for plumbing contractors — detailed — Plumbing contractors — residential service, commercial buildouts, water-heater installs, drain and sewer — typically qualify for $50K–$400K MCA advances at 1.28–1.42 factor rates over 6–12 months, with license, after-hours service revenue, and supply-house credit shaping underwriting.
- MCA for electrical contractors — detailed — Licensed electrical contractors — residential service, commercial buildouts, EV-charger installs, solar tie-ins — typically qualify for $50K–$500K MCA advances at 1.26–1.40 factor rates over 6–12 months, with license status, material price volatility, and project payment lag shaping underwriting.
- Merchant cash advance (MCA) — A lump-sum advance against future revenue, repaid via fixed daily ACH or a percentage of card sales. Legally a sale of future receivables, not a loan.
- Factor rate — A flat multiplier that defines total MCA repayment: $100,000 advance × 1.30 factor = $130,000 repaid. It is not an interest rate; it does not compound.
