HVAC companies can borrow from about $10,000 into the six figures, and many alternative lenders consider a FICO score of 500 or higher and return a decision in roughly 24 to 48 hours. The money most often goes to replacing service vehicles and diagnostic equipment, covering technician payroll through the spring and fall shoulder seasons, pre-buying condensers and furnaces before summer and winter demand peaks, and bridging the gap between finishing an install and getting paid on it.
Banks struggle with HVAC because revenue swings hard with the weather and a large share of it sits in unpaid invoices and unfinished jobs. Three flat months on a bank statement can misrepresent a profitable shop. This guide covers the products that actually fit the trade, what each realistically costs, and how to match the repayment structure to your cash-flow pattern instead of borrowing against a slow month.
Key takeaways
- Alternative HVAC financing commonly starts at $10,000 and scales into six figures for equipment and commercial project mobilization.
- Many lenders consider a FICO score of 500 or higher, weighting bank deposits and time in business over the credit score alone.
- Approval decisions from alternative lenders often arrive within about 24 to 48 hours, though no approval is guaranteed.
- HVAC revenue peaks in summer and winter, with spring and fall shoulder seasons that keep fixed costs running while service volume drops.
- Banks frequently reject HVAC firms because lumpy deposits, work-in-progress cash, and thin reserves read as instability.
- Short-term and revenue-based products are priced with a factor rate (total repaid), not an APR, so compare offers in total dollars.
- MCA relief means lowering the daily or weekly payment by restructuring the term, not paying off or buying out the balance.
Why HVAC Cash Flow Confuses Traditional Lenders
HVAC revenue clusters into two peaks: cooling calls in summer and heating calls in winter. Between them, spring and fall are shoulder seasons where service volume falls but fixed costs (technician payroll, truck payments, insurance, shop rent) keep running at full rate. A bank reviewing three months of statements pulled from a shoulder season reads a strong company as a weak one.
Four structural traits work against conventional underwriting:
- Lumpy deposits. One commercial rooftop-unit replacement can outweigh a full month of residential service tickets, so average monthly revenue looks erratic on paper.
- Cash locked in jobs. Equipment and materials are bought up front while the customer pays on completion or net-30, leaving cash trapped in work-in-progress.
- Thin retained earnings. Many shops reinvest into trucks and tools rather than building the cash reserve a bank wants to see.
- Blended owner credit. Personal and business credit are intertwined, and a single equipment purchase can dent a personal FICO score a bank treats as disqualifying.
None of this means the company is unprofitable. It means the timing of cash in and cash out rarely matches a standard bank amortization schedule, which is why many owners turn to financing built around receipts and seasonality rather than two years of flat, clean financials.
Common Funding Uses and Typical Amounts
Loan size should follow the use and how fast that use pays for itself. A replacement van bills calls the day it hits the road; a pre-season marketing push takes weeks to convert. The ranges below are rounded illustrations, not quotes.
| Funding use | Typical range (example) | Why HVAC firms borrow for it |
|---|---|---|
| Service van or truck replacement | $25,000 - $70,000 | Add route capacity or replace a vehicle before the summer rush |
| Recovery machines, gauges, diagnostic tools | $10,000 - $30,000 | Outfit a new crew or upgrade to handle newer refrigerants |
| Bulk equipment and inventory (condensers, furnaces, parts) | $20,000 - $100,000 | Pre-buy ahead of peak season or lock pricing before supplier increases |
| Payroll through a shoulder season | $15,000 - $50,000 | Retain trained technicians during spring/fall slowdowns |
| Marketing and lead generation | $10,000 - $40,000 | Fund tune-up campaigns before cooling and heating peaks |
| Commercial project mobilization | $50,000 - $250,000 | Buy materials up front on a large install before customer payment |
One rule keeps most owners out of trouble: borrow against the cash the use will generate or protect, and keep the repayment window shorter than the useful life of what you buy. Financing a five-year truck over 12 months strains the very season it was meant to strengthen.
Loan and Financing Types That Fit the Trade
Few HVAC firms run on a single product. Most owners combine tools depending on whether the need is an asset, short-term cash, or seasonal coverage.
- Equipment financing. The truck or machine is the collateral, so approval leans on the asset instead of pristine financials. Best for vehicles, lifts, and shop equipment; terms usually run 24 to 60 months.
- Short-term working capital. A fixed sum repaid over several months to about two years, used for payroll, inventory pre-buys, or bridging a slow stretch.
- Business line of credit. A revolving limit you draw on only when needed and pay interest on only what you use, which matches the on-and-off cash demands of shoulder seasons.
- Merchant cash advance (MCA) / revenue-based financing. An advance repaid as a fixed daily or weekly amount tied to receipts. Fast and forgiving on credit, but the highest cost of capital, so reserve it for genuinely time-sensitive needs.
- SBA loans. The lowest-cost option for firms that qualify, but the underwriting is slow and document-heavy, which does not help a truck that has to be replaced before next week's calls.
- Invoice factoring. Selling unpaid commercial invoices for immediate cash, useful when you have net-30 or net-60 commercial clients and money stuck in work-in-progress.
Speed and access trade off against cost. Bank and SBA money is cheapest but slowest and hardest to land; MCA and revenue-based products are fastest and most forgiving on credit but cost the most. Equipment financing and lines of credit sit in the middle and are the everyday workhorses of a well-run HVAC finance stack.
What Financing Actually Costs (Rounded Examples)
Judge every offer in total dollars repaid and dollars per period, not just a headline rate. Short-term and revenue-based products are usually priced with a factor rate (for example, a 1.25 factor on $25,000 means you repay $31,250 regardless of how fast you pay), which is not the same as an APR and can look deceptively small. The scenarios below are rounded illustrations, not offers; real terms depend on revenue, credit, and time in business.
| Scenario (example) | Amount | Structure | Approx. periodic payment | Approx. total repaid |
|---|---|---|---|---|
| Short-term working capital | $40,000 | 12-month fixed, weekly | ~$950 / week | ~$49,000 |
| Equipment financing (van) | $55,000 | 48-month, monthly | ~$1,400 / month | ~$67,000 |
| Revenue-based advance | $25,000 | ~9-month, daily | ~$155 / business day | ~$32,000 |
| Line of credit draw | $20,000 | 6-month repay on draw | ~$3,600 / month | ~$21,600 |
Two habits protect margin. Size the payment against your slowest month, not your peak: if the weekly figure is comfortable in April, it is trivial in July. And avoid stacking multiple advances at once. Layering several daily-payment products on top of each other is the single most common way profitable HVAC firms end up cash-starved in a shoulder season.
Seasonality: Borrow Before the Peak, Not During the Valley
The costliest financing mistake in HVAC is timing. Owners wait until a slow spring drains the account, then borrow under pressure at the worst rates a lender will offer. The better move is to line up capital before the season turns, while peak-season strength still shows on your statements and you negotiate from health.
A rough seasonal playbook for many US markets:
- Late winter / early spring: Secure a line of credit or pre-buy cooling inventory while winter revenue still appears on your statements.
- Summer peak: Spend on capacity (a van, a crew), not survival, and use strong months to pay down short-term balances.
- Fall: Fund heating-season inventory and tune-up marketing before the first cold snap.
- Shoulder seasons: Draw on an existing line only for real needs, and resist opening new high-cost advances to cover routine fixed costs.
Financing arranged in advance is almost always cheaper than financing arranged in a panic, because lenders price to the risk they see on the day you apply.
Qualifying, and Lowering an Existing Payment
Alternative and revenue-based lenders weigh three things more than the credit score alone: consistent business bank deposits, time in business (often six months or more), and the ratio of existing debt payments to revenue. Many consider a FICO score of 500 or higher, fund amounts starting around $10,000, and return a decision within roughly 24 to 48 hours. To move fast, have recent business bank statements, a government-issued ID, a voided business check, and basic entity documents ready before you apply. Faster decisions do not mean guaranteed approval; every file is still underwritten.
If your company already carries a merchant cash advance or revenue-based product whose daily or weekly payment has tightened during a slow stretch, the goal is relief through restructuring the payment, not eliminating the balance. Relief here means lowering the daily or weekly amount by extending the term or reworking the schedule so more cash stays in the business each week. It does not mean paying off, buying out, or consolidating away the underlying obligation. The balance and the agreement remain; only the payment pressure eases. Used carefully, that can free enough weekly cash to keep technicians on payroll through a shoulder season without stacking another high-cost advance on top.
Frequently asked questions
How much can an HVAC company borrow?
It depends on revenue, credit, and use of funds, but alternative financing commonly runs from about $10,000 for tools and marketing up to $100,000 or more for equipment, inventory pre-buys, and commercial project mobilization. A practical guide is to borrow against the cash the purchase will generate or protect, and to keep the repayment window shorter than the useful life of what you buy.
Can I get an HVAC business loan with a low credit score?
Often yes. Many alternative and revenue-based lenders consider applicants with a FICO score of 500 or higher because they weigh consistent business bank deposits and time in business more heavily than the score itself. A lower score usually means a higher cost of capital, so when time allows it is worth improving deposits and reducing existing debt load before applying.
How fast can HVAC financing be approved?
Bank and SBA loans can take weeks. Alternative lenders frequently return a decision in roughly 24 to 48 hours when you submit recent business bank statements, a government-issued ID, a voided business check, and basic entity documents up front. Funding can follow shortly after approval, which is why these products are common for time-sensitive needs like replacing a service van before peak season. Fast does not mean automatic; each application is still underwritten.
What is the best way to finance an HVAC service truck?
Equipment financing is usually the strongest fit because the vehicle itself is the collateral, so underwriting leans on the asset rather than requiring pristine financials. Terms are commonly spread across 24 to 60 months to keep the monthly payment manageable. Reserve short-term working capital and revenue-based advances for shorter-lived needs, not for a multi-year vehicle.
How should I handle financing through the slow spring and fall seasons?
Arrange capital before the season turns rather than after the account drains. A line of credit fits shoulder seasons well because you draw on it only when needed and pay interest only on the balance you use. Size any fixed payment against your slowest month so it stays comfortable year-round, and avoid opening new high-cost advances just to cover routine fixed costs during a valley.
I already have a merchant cash advance that is straining cash flow. What are my options?
The goal is relief through restructuring, which means lowering the daily or weekly payment by extending the term or reworking the schedule so more cash stays in the business each week. This is not paying off, buying out, or consolidating the balance away; the underlying obligation remains and only the payment pressure is reduced. Done carefully, it can free enough weekly cash to keep technicians on payroll through a slow stretch without stacking another advance on top.
