Best business loans for HVAC companies

For a heating and air conditioning company, the best option depends on what the money is for. For fast capital in peak season, or to buy equipment before you get paid on an install, our recommended funder is Merchant Fund Express: it often decides in 2 to 4 hours, works with credit from FICO 500 and reviews your deposits. For vans and tools, an equipment loan usually costs less. For commercial contracts that pay in 30 or 60 days, factoring fits better. And if you have good credit and time, an SBA loan or a bank line is usually cheapest.

Below you'll find the ranking, a comparison table and how to build your financing around the seasons. For the general industry guide, read business loans for HVAC companies.

The best HVAC financing options, ranked

1. Merchant Fund Express (recommended funder). The option for when work hits all at once: you've sold five installs, the distributor wants payment for the equipment, and the customer pays when you finish. It reviews your sales and deposits, not just your score, with amounts from $5,000 to $5,000,000, decisions often in 2 to 4 hours, credit from FICO 500 and no collateral in most cases. Applying is free and doesn't affect your credit, it accepts applicants with an ITIN (no SSN needed), and Spanish-speaking support is available.
2. Equipment loan. For a service van, a refrigerant recovery machine, vacuum pumps or diagnostic tools. The equipment serves as backing, so the cost is usually lower than unsecured capital, and the term tracks the equipment's useful life.
3. Line of credit. Ideal for the seasonal swing: you draw in June for inventory and payroll and pay it down in September when you collect. Bluevine offers lines up to $250,000 with FICO 625+, 12 months in business and $10,000 a month in revenue; OnDeck, $6,000 to $200,000 with 1 year, $100,000 a year and FICO 625; and the Wells Fargo BusinessLine runs $10,000 to $150,000 with no collateral, for guarantors with credit around 680 (per their sites, checked October 2026).
4. Invoice factoring. If you install systems in commercial buildings, restaurants or new construction, you're probably paid in 30, 60 or 90 days. Factoring advances most of those invoices, and approval depends mostly on who owes you, not just your own credit.
5. SBA 7(a) or SBA Express loan. Works for working capital, equipment and even buying another HVAC company. The 7(a) goes up to $5 million. It's usually cheapest if you qualify, but it takes more paperwork and more time. Since March 2026, every owner must be a U.S. citizen or national.
6. CDFI or microloan. For companies starting out with one van that want tools or inventory. SBA microloans go up to $50,000; they usually cost less and many include coaching.

How we chose

We compare on criteria you can check: speed, minimum time in business, minimum credit, acceptance of ITIN or no-SSN owners, documents, amounts and collateral. We don't give ratings or use invented statistics, and every company's facts come from its official site, checked in October 2026. The full method is in how we rank business funding options.

For HVAC we add one more question: does the option fit the season? Financing with high fixed payments that kick in during January, when calls slow down, can be a problem even if it's cheap. That's why we don't rank on cost alone, but on how well each option matches the way money actually flows into your company.

The HVAC cash cycle

Knowing when your money goes out and when it comes in tells you what financing you need. For a typical heating and air conditioning company:

• Spring: you gear up. You stock parts, service your vans, hire techs and run preventive maintenance.
• Summer: emergency calls and replacements spike. You pay overtime, buy equipment to install and sometimes don't have enough hands.
• Fall: you collect on what you installed and prep for heating season.
• Winter: in cold climates, heating work; in warm climates, calls drop and cash gets tight.

Financing is there to smooth out that cycle. A line of credit or fast working capital in spring lets you buy at a discount and hire on time. An equipment loan handles the vans without touching your cash. And factoring speeds up slow commercial payments.

How to combine options without drowning

Many healthy HVAC companies use two tools at once, each for its own job. For example: an equipment loan for the new van, with payments that last as long as the van does, and a line or working capital for seasonal inventory, repaid as you collect on installs. What doesn't work is using short-term capital for something that produces for years, or stacking daily payments from several sources. Before adding new debt, total up all your payments and compare them with your deposits in your slowest month. For a walkthrough with example numbers, read example: an HVAC company financing equipment.

What funders ask an HVAC company for

1. Business bank statements for three to six months, ideally covering a busy season.
2. Licenses. Your state contractor or HVAC license and, for handling refrigerants, the EPA certification your techs need.
3. Insurance: general liability, plus workers' comp if you have employees.
4. Signed contracts or proposals if you're asking for capital for specific jobs.
5. Receivables if you'll use factoring, with your commercial customers' details.
6. Quotes for the equipment or vans you plan to buy.
7. Tax returns, especially for the SBA and banks.

A tip: deposit every payment into the business account, including checks from residential customers. That way your statements show what your company really bills.

Common mistakes when financing an HVAC company

• Applying in the middle of a heat wave. When the phone won't stop ringing, you have no time for paperwork. Apply before the season.
• Buying vans with expensive capital. If you can finance the van with the van as backing, do it; save fast capital for what's urgent.
• High fixed payments in the slow season. Check how January or February will look before you accept a fixed payment.
• Taking advances to cover other advances. If you already have several, work on lowering the payment instead; see how to lower your daily advance payment.
• Not collecting deposits. On large residential installs, a customer deposit shrinks what you need to finance.
• Forgetting retainage. On commercial contracts, part of your payment may be held until the job is done; factor it into your cash planning.

When Merchant Fund Express makes sense

It makes sense when you have work sold and need the money in days: equipment for signed installs, extra techs for the season, or repairs on a van that has you off the road. It also fits when your credit doesn't clear the bank's bar but your deposits show your company is billing.

It isn't the first choice if you can wait weeks and qualify for an SBA loan or a bank line; in that case, those usually cost less. If speed is what you need, you can apply with Merchant Fund Express. Applying is free, doesn't affect your credit, and tells you how much you could get before you commit to the distributor. If a lot of your billing is commercial, also compare accounts receivable factoring. Prefer Spanish? Leer en español.
