How HVAC, Plumbing & Electrical Contractors Actually Fund the Busy Season (and Survive the Slow One)
When it's 96 degrees in Tampa and the phone won't stop ringing, nobody hands you extra techs, a spare van, and a pallet of condensers on credit. The trades run on cash you often don't have yet — payroll hits Friday, the supply house wants payment in 30 days, and that commercial GC pays in 60 if you're lucky. This guide walks through how HVAC, plumbing, and electrical contractors actually finance that gap: what fits, what it costs, and where the traps are.
The cash-flow reality of running a trades business
HVAC, plumbing, and electrical shops share a cash-flow pattern that most generic financing advice ignores: your costs are front-loaded and your revenue is back-loaded, and the gap between them widens exactly when business is best.
In Florida, the demand curve is brutal and predictable. Summer heat means AC failures stack up faster than you can run calls. Hurricane season drives panel upgrades, generator installs, and emergency electrical work. Even the mild winters bring a burst of heat calls on the first cold snap. To capture any of that, you spend first — hiring techs, stocking trucks, putting down deposits on equipment — weeks before the revenue lands.
Meanwhile the outflows don't flex. Payroll runs weekly or biweekly whether you've been paid or not. Supply houses typically want net-30, and newer accounts often get COD until they've built history. Materials prices haven't been kind either — copper, wire, switchgear, and the refrigerant transition have all pushed job costs up, and larger components can carry long lead times that force you to order (and pay) earlier than you used to.
None of this means the business is broken. It means the business consumes working capital as it grows, and the owners who plan for that tend to have much calmer summers than the ones who discover it mid-July.
Residential service vs. commercial installs: two different funding problems
Most shops run both kinds of work, and each one strains cash differently.
Residential service calls are the good kind of cash flow: small tickets, high volume, and payment at the door — usually card or check the same day. The constraint here isn't collections, it's capacity. Every call you can't run because you're short a truck, a tech, or the parts on the shelf is revenue that goes to a competitor and doesn't come back. Funding for this side of the business is about adding capacity ahead of demand.
Commercial installation contracts are the opposite. The tickets are large, but you're typically fronting labor and materials for weeks or months against progress billing. Retainage — commonly in the range of 5-10% — gets held until the project closes out, and pay-when-paid clauses mean your money can sit behind the GC's money. A profitable commercial job can leave you cash-poor for its entire duration. Funding for this side is about float: bridging the gap between what you've spent and what you've billed but not collected.
The right financing depends on which problem you're solving — and if you're solving both at once, it often takes more than one tool.
The financing products that actually fit — and their trade-offs
Before anything else: the cheapest capital in the trades is usually negotiated supplier terms. If your supply house will move you from COD to net-30, or net-30 to net-60, that's free float. Push on it first. When terms alone don't cover the gap, here's what the market typically offers.
Equipment financing (trucks, vans, and major gear)
If the money is going into a service van, a sewer camera, a mini excavator, or shop equipment, equipment financing usually fits best. The equipment itself is the collateral, so approvals tend to be more forgiving than unsecured credit, terms run longer, and your working capital stays free for payroll and materials. The trade-offs: it only covers the equipment (not the tech who drives the van), it can take days to a couple of weeks depending on the lender, and some programs want a down payment.
Business line of credit
For a seasonal business, a line of credit is arguably the best all-around structure — draw during the spend-up, repay during the collect-down, pay interest only on what you use. The catch is qualifying. Bank lines typically want two-plus years in business, solid credit, and clean financials, and banks have been known to reduce or freeze lines when conditions tighten. Non-bank lines are easier to get but cost more. If you can qualify for a bank line, it's usually worth the paperwork.
Revenue-based financing (merchant cash advance)
An MCA isn't a loan — it's a purchase of your future receivables at a discount. A funder advances you a lump sum today, and you repay a fixed total (the advance times a factor rate, often somewhere in the range of 1.15 to 1.45) through daily or weekly ACH debits, or as a percentage of sales. It's commercial financing, not a consumer loan, and it's priced above bank debt for a reason: it's fast — often 24-48 hours from application to funding — and it's tolerant of imperfect credit because approval leans on your deposit history, not your FICO score. Advance sizes for established trades businesses commonly run from $25K up to several hundred thousand, depending on revenue.
The honest trade-off: fixed daily or weekly debits don't care that it's a slow February. An MCA can make real sense when a clearly profitable opportunity is time-sensitive — staffing up before the summer surge, or covering mobilization on a signed commercial contract whose margin comfortably outruns the cost of the money. It makes much less sense as a patch for a business that's losing money, because the repayment schedule will tighten the squeeze, not relieve it.
SBA 7(a) loans
The cheapest meaningful money most small contractors can access — but the slowest. Expect real underwriting: tax returns, financials, personal credit, sometimes collateral, and a timeline that often runs several weeks or more. Great for planned moves like an acquisition, a shop purchase, or a large refinance. Nearly useless when the opportunity or the problem is this week.
Invoice factoring / AR financing
On paper, factoring is built for the commercial-install problem: sell your receivable, get most of the cash now. In practice, construction receivables are harder to factor than most — retainage, progress billing, and pay-when-paid clauses make some funders avoid the sector entirely, and those who do take it price for the risk. It's worth exploring if commercial AR is your main bottleneck, but go in knowing the pool of willing funders is smaller.
Side-by-side: how the options compare
Relative cost below is exactly that — relative. Actual pricing depends on your revenue, time in business, credit profile, and the funder.
| Product | Best use | Typical speed | Relative cost | Watch out for |
|---|---|---|---|---|
| Supplier terms | Materials float on any job | Immediate once negotiated | Lowest | Limits are finite; late payment burns the relationship |
| Equipment financing | Trucks, vans, major tools | Days to ~2 weeks | Low-moderate | Only covers equipment; possible down payment |
| Line of credit | Seasonal swings, recurring gaps | Days (non-bank) to weeks (bank) | Low (bank) to moderate (non-bank) | Hard to qualify at banks; lines can be cut |
| Revenue-based advance (MCA) | Fast capital for time-sensitive, profitable moves | Often 24-48 hours | High | Fixed debits continue through slow weeks; avoid stacking |
| SBA 7(a) | Large, planned investments | Several weeks or more | Lowest of the loan options | Paperwork-heavy; too slow for emergencies |
| Invoice factoring | Commercial AR with long payment cycles | Days once set up | Moderate-high | Many funders avoid construction receivables |
What funders look at in an HVAC, plumbing, or electrical file
Whatever the product, most underwriting for trades businesses starts in the same place: your last three to six months of business bank statements. Funders are reading for deposit consistency, average daily balance, and negative days or NSFs. A shop with steady daily card deposits from residential service work reads as lower risk than one whose revenue arrives as a few lumpy GC wires — even at the same annual revenue.
That has a practical timing implication: applying at the end of a strong season looks very different from applying at the bottom of the trough. If you know the summer surge is coming and you'll need capital to staff for it, starting the conversation in spring — while your trailing statements still show winter softness — will generally produce weaker offers than you'd see later. Plan the timing like you'd plan the job.
Beyond the statements, expect funders to weigh time in business (two-plus years opens more doors), an active contractor's license and insurance, existing advance balances (stacked positions are a red flag almost everywhere), and — for larger amounts — your contract pipeline. Personal credit matters a lot at banks and for SBA, and considerably less for revenue-based products, though it's rarely ignored entirely.
Frequently asked questions
How fast can a contractor actually get working capital?
It depends on the product. Revenue-based advances often fund in 24-48 hours once your statements are in. Non-bank lines of credit and equipment financing typically run a few days to a couple of weeks. Bank lines and SBA loans are measured in weeks, sometimes longer. Speed and cost trade off against each other — the fastest money is rarely the cheapest.
Can I get funded with average or damaged credit?
Often, yes — but the options narrow and the price rises. Revenue-based funders lean primarily on your bank deposit history rather than your credit score, and equipment lenders take comfort from the collateral. No honest broker will promise an approval, though: every funder underwrites differently, and the only way to know is to submit a file.
Does JLFG lend the money itself?
No. JLFG is a brokerage, not a lender. We compare options across a network of lenders and funders and help you read the offers — including the fine print. Our compensation is paid by the lenders, never by you, and we'll tell you plainly when we think an offer is a bad fit, because a deal that hurts your business doesn't do us any good either.
Is a merchant cash advance a good idea for a seasonal business?
It can be — and it can be a mistake. It fits when a specific, profitable, time-sensitive opportunity clearly outruns the cost of the money and you'll repay during a strong-revenue stretch. It's risky when the repayment window overlaps your slow season, because fixed daily or weekly debits keep coming regardless of your call volume. If your need is recurring rather than one-off, a line of credit is usually the better structure to work toward.
