HVAC is one of the most capital-intensive trades in small business, and the capital is split across three places that almost never line up at the same time. Trucks need replacing on a 5 to 7 year cycle. Inventory has to be on the shelf before the first heat wave of the year. And payroll has to clear during shoulder months when service calls dry up. If you are looking for an hvac business loan, the right answer is rarely a single product. It is a stack sized to the trucks, the parts room, and the cash flow valleys.
This guide walks through how heating and cooling business loan structures actually get built by people who fund HVAC contractors every week. We cover the three categories where the money goes, what underwriters look at, and why the software you use in the field has started to matter more than the year on your tax return.
Fleet and inventory: where HVAC capital actually goes
The first place capital disappears is the truck. A properly equipped service van is not a $35K Transit off the lot. It is a Ford F-250 or a Transit in the $40K to $75K range, plus another $5K to $15K to fit it out with shelving, parts bins, a power inverter, ladder racks, and a refrigerant recovery setup. A 5-truck shop has $300K to $500K rolling around the streets on any given Tuesday, and most of that should be financed rather than paid for in cash. Our equipment financing program funds service vans and box trucks with the vehicle itself as collateral, which keeps rates lower than an unsecured term loan and term-matches the loan to the useful life of the asset. For the lease versus finance versus buy math, our breakdown of equipment financing structures walks through it cleanly.
The second line item is inventory. Condensers run $1K to $4K each, residential furnaces $1K to $3K, and you also carry sheet metal, ducting, refrigerant, copper line set, thermostats, capacitors, and contactors. A typical mid-size residential shop carries $50K to $200K of parts at any time. Larger contractors doing new construction or commercial chiller work run $500K to $2M in inventory plus jobsite material. This is working capital, not equipment. You do not finance a pallet of refrigerant on a 5-year note. You draw from a business line of credit in March, pre-buy ahead of the price hike that hits every spring, and pay it back through summer cash flow.
The third line item is the build-out if you own the shop and yard. Owner-occupied real estate with a fenced material yard, a parts room, and a small office is exactly what SBA 504 is built for. Twenty to twenty-five year amortization on the real estate piece, separate financing on the heavy fixed assets. For a contractor who has been renting a metal building for eight years, 504 often pencils out cheaper than the next lease renewal.
Double-peak seasonality and why the line of credit wins
HVAC has a revenue curve that nothing else in the trades looks quite like. AC season runs May through September with the real peaks landing during July and August heat waves. Furnace season runs November through February, with the biggest weeks being the first hard freeze and the post-holiday cold snap. The problem is the shoulder months. March, April, and October are revenue valleys, and for residential-heavy shops they can be brutal. Payroll, truck payments, insurance, and rent do not take a break in April just because the phone is quiet.
This is why a business line of credit is the most-used financing product in HVAC, more than equipment financing and more than term loans. The right facility size is roughly one to two months of operating expense, which for most independent contractors lands between $100K and $500K. The playbook is straightforward. Draw in early spring to fund refrigerant pre-buy, tech training and certifications, and any spring marketing push. Repay through July and August when service calls and replacement jobs are stacked up. Draw again in October to fund furnace inventory and the winter payroll bridge. Repay through December and January.
The other thing a line does is keep you out of MCA territory. A lot of HVAC owners get into trouble because they wait until April to realize cash is tight, then take a merchant cash advance with daily ACH pulls that strangle the summer when they should be banking cash. Our guide on working capital versus line of credit covers the difference, and our piece on MCA versus a real business loan walks through what an MCA actually costs once you annualize it. For seasonal trades broadly, our landscaping and seasonal business funding guide covers the same seasonality logic from the green side.
If you need to fund a specific job rather than a seasonal cycle, a short working capital advance or a bridge loan can cover a 30 to 90 day gap while you wait on a commercial customer to pay. Just size the term to the receivable, not to your gut.
Why ServiceTitan and Housecall Pro quietly make you more fundable
Here is the part that most HVAC owners do not realize about modern underwriting. The software you run in the field changes how a lender sees your business. A shop running ServiceTitan, Housecall Pro, or Jobber generates a clean transaction history, a dispatched-versus-completed ratio, average ticket data, and a real list of active maintenance plan members. All of that is visible to an underwriter through an integration or a simple CSV export. Compare that to the paper-and-QuickBooks shop where revenue verification means 6 months of bank statements and an underwriter guessing at billing accuracy from deposit patterns. The platform shop gets faster approvals, cleaner pricing, and frequently a 20-30% larger approved amount on the same revenue base.
The biggest single lift inside those platforms is maintenance plan ARR. A shop with 500 members on a $200 per year tune-up plan has $100K of recurring revenue, charged on autopay, that hits the bank every month regardless of weather. That stabilizes underwriting the same way membership ACH pulls do for a medical spa (see our piece on med spa financing for the parallel). Recurring revenue smooths the shoulder months, and shoulder months are exactly what underwriters worry about when they read bank statements. Our guide on how lenders read bank statements walks through what they actually look for.
Concretely: an HVAC contractor doing $1.5M annual with no maintenance plans and no field-service platform typically prices into higher-rate revenue-based products, often in the 20s. The same contractor at $1.5M with 600 active maintenance members generating $120K of ARR, running ServiceTitan with 18 months of clean dispatch data, frequently qualifies for bank-rate term loans or a real SBA 7(a) at the 2-year mark. That is a five-figure-per-year difference in interest on the same loan amount. For sister-trade context, our electrical contractor financing post covers the same field-service-platform leverage from the sparky side.

Frequently Asked Questions
Q. Can I finance a used service van or box truck?
A. Yes. Most equipment lenders will finance used commercial vehicles up to roughly 8 to 10 years old with reasonable mileage, typically through a dealer or a documented fleet sale. Private-party van purchases are harder to finance because the lender cannot verify service history or condition. If you are buying from a competitor going out of business, ask for the maintenance records before you sign.
Q. I am a one-truck shop in year two. What can I qualify for?
A. If you are doing at least $10K a month in revenue and you have been in business 6+ months, you are in the qualifying range for our revenue-based products. Equipment financing on a second van is usually the easiest first approval because the truck itself is the collateral. A small line of credit, $25K to $75K, is the next step once you have 12 months of clean deposits.
Q. How big a line of credit do I actually need?
A. Size it to one to two months of fully loaded operating expenses, including payroll, truck payments, insurance, rent, and a realistic inventory pre-buy. Most independent residential shops land between $100K and $500K. Going smaller leaves you exposed in the shoulder months. Going larger usually means you are paying for capacity you will not draw against.
Q. Will daily MCA pulls hurt my chances of getting an SBA loan later?
A. Yes. SBA underwriters scrutinize existing debt service, and daily ACH pulls from a merchant cash advance look like a serious cash flow drag on bank statements. We have refinanced MCAs into SBA 7(a) loans, but the cleaner path is to size the right product the first time. Our piece on MCA versus business loan walks through the comparison.
Q. Does running ServiceTitan or Housecall Pro really change my approval?
A. It changes underwriter confidence, which usually translates to better pricing and a larger approved amount. The platforms give us clean ticket data, dispatch logs, and an exportable list of active maintenance members. That is the difference between an underwriter guessing at your revenue mix and seeing it directly. It will not turn a 540 FICO into a 720, but it will frequently move pricing 3 to 5 points on the same file.
HVAC financing is not one decision. It is three or four decisions stacked together, and getting the structure right at the start is the difference between a shop that compounds and a shop that stays cash-poor every April. The contractors who do this well treat their lender like their parts supplier. Steady relationship, clean paperwork, fair pricing, available when the season turns. If you are adding a truck, pre-buying for summer, or buying out a partner, we can size the right stack. Apply in 3 minutes with a soft credit pull. Find out More.
