Financing an HVAC Business: Fund the Gap, Not Just the Gear
You finance an HVAC company three ways, and the one that matters most is the one contractors reach for last. Not equipment. Working capital. You buy the materials and pay the crew on an install, then wait 30 to 60 days for the check, and the work itself bunches into a few hot and cold months a year. A line of credit carries that gap. Equipment financing buys the vans and the machines on their own term. An SBA 7(a) is for buying a company or the building. Match the money to the timing, not the rate.
Bottom line
HVAC contractors finance three different things, and the biggest one surprises people. It is not equipment, it is working capital. You front materials and labor, then wait 30 to 60 days to get paid, and demand swings hard by season, so a business line of credit up to $250,000, drawn ahead of the busy season and repaid as invoices clear, is the core tool. Finance vans and machines separately at up to 100% on a matched term, and use an SBA 7(a) only to buy a company or real estate. Match the product to your cash-conversion cycle, not the headline rate.
The HVAC financing question is really about timing
An HVAC company can be profitable and cash-poor in the same week, for one plain reason: you spend on materials and labor before the customer pays, and the work bunches into a few peak months. So the real question is not how much to borrow. It is which dollar you are funding, and how fast it turns back into cash.
Sort your need into three buckets and the products line up almost on their own. There is the timing money, the cash that bridges the gap between doing the work and getting paid, and the gap between a dead March and a slammed July. There is the asset money, the vans and the machines that a lender can take back if you stop paying, so they finance themselves cheaply on their own term. And there is the big planned money, buying a competitor or the building, where an SBA loan is the cheapest capital you will ever qualify for.
Most owners collapse those three into one loan and then wonder why the payment feels wrong. It feels wrong because a five-year truck and a 60-day receivable are not the same problem. The seasonal side of this is its own discipline, and the guide to seasonal working capital walks through sizing the borrowing to your slowest month rather than your best one.
HVAC business financing and HVAC customer financing are two different things
Search “HVAC financing” and you get two unrelated products wearing the same name. One is capital for your company: a line of credit, equipment loans, an SBA loan. The other is a consumer program you offer homeowners at the kitchen table, so they can pay for a $12,000 system over time while you get paid in full up front. This guide is about the first.
The distinction matters because the two solve opposite problems. Customer financing is a sales tool. It raises your close rate and your average ticket by removing the price objection, and it is run by consumer lenders like Synchrony and GreenSky who pay you and collect from the homeowner. Business financing is a cash-flow tool. It funds the truck, the crew, and the gap while you wait to collect. You may well want both, but they are separate decisions with separate providers, and confusing them is the most common wrong turn contractors take when they start looking.
What each product actually funds in an HVAC business
A growing shop rarely runs on one product. A typical year stacks a line of credit for the timing money, equipment financing for a new van, and maybe a fast advance to jump on a commercial bid. Here is what each one is for, and where it fits.
Business line of credit: the core HVAC tool
A line of credit up to $250,000 charges interest only on what you draw, which is exactly the shape an HVAC company needs. Draw to buy materials and cover payroll on an install, repay as the customer pays, then draw again for the next job or the next season. It carries the receivables gap and the seasonal swing without locking you into a fixed monthly payment during the months you collect the least. This is the product most contractors underuse and need most.
Equipment and fleet financing: the vans and the machines
Service vans, install trucks, recovery and reclaim machines, brazing and vacuum gear, and shop tools all collateralize themselves, so equipment financing covers up to 100% of the cost and funds in 24 to 48 hours, starting near 6% APR on strong files and running to about 20% on higher-risk ones. Term it to the life of the asset. A wrapped, stocked van lasts a decade, so it belongs on a multi-year loan, not a short advance you clear long before the truck stops earning.
Working capital and revenue-based advances: speed for a gap
When a slow shoulder season leaves payroll short, or a large commercial job lands and you need to move on materials this week, a working-capital term loan or a revenue-based advance funds up to $400,000 to $500,000 in about a day on bank-statement cash flow. It costs more, roughly 12% to 35% or higher, and it is the right tool only for a defined, short payback. It is the wrong tool for a gap a cheaper line of credit was built to cover.
SBA 7(a): buying a company or the building
For acquiring another HVAC company, buying out a partner, or purchasing the shop and yard you operate from, the SBA 7(a) is usually the cheapest capital a contractor can get. It reaches $5 million, amortizes up to 10 years on a business purchase and 25 on real estate, and in 2026 prices around Prime plus 2.25% to 4.75%, roughly 9.75% to 12.25% APR with Prime near 7.5%. The trade is speed: figure 30 to 90 days to close.
Invoice and AR financing: for the commercial contractor
If a chunk of your work is commercial or new-construction, you invoice on net-30 or net-60 and wait, sometimes with retainage held past that. Invoice financing advances up to about 90% of an approved invoice within a day and underwrites the credit of the customer who owes you, not just your own file. For a contractor whose cash is stranded in receivables rather than in a slow month, it frees the exact dollars a general line of credit sometimes cannot.
The one that trips owners up is the split between the line and the advance. Both give you fast cash, but they behave nothing alike once the money is out. A business line of credit only charges you for what you draw and shrinks its cost as you repay, while a revenue-based advance is priced by a fixed factor and debits you daily whether cash is tight or not. If you are weighing the two, the line of credit versus merchant cash advance comparison lays the trade out in full. Buy the vans and machines through equipment financing and keep them off the line entirely.
The gap is the real need, and the season rewards the smart move
Here is the part most HVAC financing articles skip. Your cash does not run short because the business is failing. It runs short because the business is working: every job you take spends money before it earns it, so the busier you get, the tighter the account feels right up until the invoices land. Growth eats cash. That is normal, and it is exactly what a line of credit is built to smooth.
The season turns that from a problem into an opportunity if you plan for it. You have to staff up and stock up six to eight weeks before the cooling season peaks, which is the same stretch when last season’s cash has drained down. Draw a line ahead of the curve instead of scrambling into it, and you show up to July already staffed and stocked. Many distributors sweeten this with a pre-season order discount, and the math is worth running: if a line at roughly 10% APR lets you capture a 3% to 5% pre-buy on a large equipment order, the discount can more than cover the interest, and the borrowing pays for itself.
The commercial side has its own trap: retainage. On new-construction and larger commercial jobs, the general contractor holds back 5% to 10% of every invoice until the project closes, sometimes six months to a year out. That is your margin, sitting on someone else’s books. Contractors who do heavy commercial work should plan their borrowing around it the way a bonded builder does, and the guide to working capital for construction bonding covers how a committed line and invoice financing free the cash a daily-debit advance quietly ties up.
Two moves, in real dollars
Round numbers make the trade-offs visible. Here are the two that come up most, carrying a commercial job through slow-paying terms and putting one more stocked van on the road, on figures you can re-run with your own quote.
Carrying a $180,000 commercial rooftop job
~$2,774 to carry it
A rooftop changeout on a retail strip: about $90,000 in equipment and roughly $45,000 in labor, crane time, and disposal across three weeks, so you are out about $135,000 before you invoice. Terms are net-60, and the check really lands closer to 75 days out. Draw that $135,000 on a line of credit at about 10% APR and carry it for 75 days, and the interest is about $2,774. On a job with even a 30% gross margin, roughly $54,000 of gross profit, that carry is a rounding error. What the line actually buys is the ability to take the job at all without starving payroll on the residential side.
Putting one more stocked van on the road ($55,000)
~$1,142/mo, self-funding
Call it $42,000 for the chassis and about $13,000 to upfit it with shelving, a ladder rack, and a wrap, so $55,000 on the road. Financed at about 9% over five years, that is roughly $1,142 a month, and Section 179 can write off the full price the year you place it in service. Put one more tech in that van running six to eight service calls a day at an average ticket around $350, and it grosses more in a week than the payment costs in a month. The van pays for itself the same way the last one did, and it never touches the line you need for the season.
The test: the number on the quote is never the whole number. Behind the van sit fuel, insurance, and the tech’s pay before the route fills. Behind the line sits the discipline to repay it as the invoices clear, so a bridge does not quietly become a balance you carry into the slow season. These are round-number illustrations. Run yours against a real quote.
Which product for which HVAC need
The same shop can touch four or five of these in a single year. The table lines up what each one funds, how much it reaches, what it costs, and how fast it moves, so you can match the product to the need instead of the other way around.
| Product | Best use in a shop | Typical amount | Cost / structure | Speed |
|---|---|---|---|---|
| Business line of credit | Receivables gap, seasonal swings, pre-season pre-buy | Up to $250K | Revolving, interest only on the draw | Same-day to 24 hrs |
| Equipment and fleet financing | Service vans, install trucks, recovery machines, shop tools | Up to $1M+ (to 100%) | ~6% to 20% APR, termed to asset life | 24 to 48 hrs |
| Working capital / revenue advance | A shoulder-season payroll gap, jumping on a big job fast | Up to $400K to $500K | Higher cost, ~12% to 35%+ | ~24 hrs |
| SBA 7(a) | Buying a company, a partner buyout, shop real estate | Up to $5M | ~9.75% to 12.25% APR, up to 10 yr (25 on real estate) | 30 to 90 days |
| Invoice / AR financing | Commercial net-30/60 invoices and retainage | Up to ~90% of invoice | Fee per invoice, priced on the payer | ~24 hrs |
Read it this way: the line of credit is the everyday tool, the SBA loan is the cheapest money and the slowest, and everything in between trades cost for speed. When the need is fast and recurring, reach for the line, not the SBA loan. When it is large and one-time, do not reach for the daily-debit advance. If the big move is buying another company, the guide to financing a business purchase runs the equity-injection and coverage math that decides the price you can pay.
The mistakes that cost HVAC owners money
None of these is the interest rate.
The loan is not the hard part. The damage comes from four assumptions that feel reasonable right up until the shoulder season hits or the commercial check runs late. Read them before you sign.
Reaching for an equipment loan when the problem is cash timing
A van is the easy thing to finance, so contractors finance the van, then wonder why the account is tight in April. The van was never the problem. The gap between spending on a job and collecting on it is, and so is the shoulder season. Size a line of credit to that gap first. The rolling stock can wait for its own loan on its own term.
Covering a slow shoulder season with stacked advances
Spring goes quiet, payroll is due, and a fast advance feels like the fix. Then a second advance covers the first, and the daily ACH debits land hardest in the exact months you collect the least. Stacking merchant cash advances is one of the quickest ways a profitable seasonal trade runs itself into the ground. A line of credit that shrinks when you draw less is the honest version of the same speed.
Buying a ten-year van on an eighteen-month product
A wrapped, stocked service van earns for a decade. Put it on a line of credit or a short revenue advance and you finish paying for it years before it stops working, tying up cash you needed for the next season along the way. Match the term to the life of the asset. Long-life steel goes on a multi-year equipment loan; the software and the small tools that turn over fast can be expensed.
Sizing the line to your best month and forgetting retainage
Underwrite your own borrowing the way a lender does, off your slowest month, not off July. And on commercial work, remember the 5% to 10% a general contractor holds back until the job closes, sometimes a year out. That retainage is your margin, sitting on someone else's balance sheet. A committed line or invoice financing frees it. Plan for it before you take the job, not after the check is late.
The through-line is simple: plan the money the way you plan a changeout. Know what you are funding, know what backs it, and match the term to how fast the cash comes back. The daily-debit stacking trap is worth studying on its own, because it is the one that ends otherwise-healthy shops, and it sits near the top of the funding mistakes that cost the most. Get the structure right and the financing becomes the part of the business you worry about least.

Frequently asked questions
How do HVAC contractors finance their business?
Three products cover almost every need. A business line of credit carries the gap between paying for a job and collecting on it, plus the seasonal swings. Equipment financing buys service vans, install trucks, and machines at up to 100% of cost on a term matched to the asset. An SBA 7(a) funds buying another company or your shop's real estate. The biggest need is usually working capital, not equipment.
What is the difference between HVAC business financing and HVAC customer financing?
HVAC business financing is capital for your company: a line of credit, equipment loans, an SBA loan. HVAC customer financing is a consumer payment program you offer homeowners so they can spread a $12,000 system over time while you collect in full up front. One funds your business, the other helps you close bigger tickets. Providers like Synchrony and GreenSky run the consumer side. This guide is about the business side.
Can a new HVAC business get a loan?
Often yes, though the product depends on the age of the business. Equipment financing is the most accessible, because the van or machine secures the loan, and it can fund a company with only a few months of history. Working capital and revenue-based advances usually want six or more months in business and around $15,000 in monthly revenue. SBA loans and bank lines want two years and a 680 credit score. The asset-backed door opens first.
How do I get working capital for the busy season?
Set up a business line of credit before the season, not during it, and draw on it as you staff up and stock up. The clean move is to size the line to your slowest month and your net-terms gap, then draw ahead of demand and repay as the invoices clear. Some contractors also use a line to capture a distributor's pre-season order discount, where the savings can outrun the interest.
Should I finance HVAC service vans or pay cash?
Financing usually wins for a working company. A stocked van runs $45,000 to $70,000, and paying cash for it drains the same working capital you need to carry jobs and payroll through the season. Equipment financing covers up to 100% on a term matched to the van's ten-year life, and Section 179 lets you write off the full price whether you finance or pay cash. The van earns more than its payment.
What credit score and revenue do HVAC lenders want?
For an SBA loan or a bank line of credit, plan on a 680 or higher personal credit score and about two years in business. Equipment financing and revenue-based advances flex well below that, often funding around 600 FICO when the asset or the cash flow is strong, with roughly $15,000 in monthly revenue and six months of operating history. The stronger your deposits and your collateral, the less your personal score decides the file.
