Best business loans for HVAC companies in 2026
The best financing for most HVAC companies is a business line of credit to carry payroll and inventory through the shoulder seasons, plus equipment financing for service vans and tools. An SBA 7(a) loan is the lowest-cost way to buy out a retiring competitor, which is a common way HVAC companies grow.

The 4 best options, ranked
1. Business line of credit Best for shoulder seasons
Spring and fall are quiet between heating and cooling demand. A line covers technicians and overhead in those months and is paid down when the first heat wave or cold snap hits.
Watch for: Some lenders add draw or maintenance fees, and a limit can be cut at renewal. Business line of credit guide →
2. Equipment loan Best for vans and tools
Service vans, recovery machines, and diagnostic tools are financeable on their own value, with terms matched to how long they will stay on the road.
Watch for: Older or highly specialized equipment gets shorter terms and higher rates. Equipment financing guide →
3. SBA 7(a) loan Best for buying another HVAC company
Acquiring a competitor's customer list and maintenance agreements is a long-term asset. A 7(a) loan spreads the price over as much as 10 years at a capped rate.
Watch for: Heavy documentation, and the timeline rules it out for anything urgent. SBA loan guide →
4. Online term loan Best for stocking units before peak season
A fixed loan for a one-time bulk purchase of condensers and furnaces can capture distributor pricing ahead of the rush, with a payoff date you can plan around.
Watch for: A longer term lowers the payment but raises the total interest you pay. Term loan guide →
Side-by-side comparison
| Option | Verdict | Cost basis | Funding speed | Qualifies on |
|---|---|---|---|---|
| Business line of credit | Best for shoulder seasons | Representative 8%–30% APR, charged only on what you draw | Often days | Revenue, time in business, and credit |
| Equipment loan | Best for vans and tools | Representative 8%–30% APR, with the term matched to the equipment's useful life | Days to weeks | The equipment is the collateral, which can offset a thinner credit profile |
| SBA 7(a) loan | Best for buying another HVAC company | Capped at 10.00%–13.50% by loan size (prime plus the SBA maximum spread) | Weeks to months | Generally stronger credit and two or more years in business |

What it costs
A line of credit charges interest only on the balance you have drawn. This is the monthly interest on a carried draw, before any principal is repaid:
| Carried draw | At 8% APR | At 19% APR | At 30% APR |
|---|---|---|---|
| $25,000 | $167 | $396 | $625 |
| $75,000 | $500 | $1,188 | $1,875 |
| $150,000 | $1,000 | $2,375 | $3,750 |

What lenders look at
- Recurring revenue from maintenance agreements, which lenders value because it is predictable.
- The split between residential service calls, which pay on the spot, and commercial work, which pays on terms.
- Seasonality in your bank statements. Lenders want to see that the slow months are survivable.
Mistakes to avoid
- Opening a line of credit after the slow season has already drained the account. Apply while the bank statements look strong.
- Tying up your own cash to carry customers' installs. Offer consumer financing through a third party and get paid up front.
Frequently asked questions
- What financing do HVAC companies use most?
- A line of credit for seasonal cash flow and equipment financing for vehicles. Larger moves such as buying another company usually go through an SBA 7(a) or a bank term loan.
- How can an HVAC company finance service vans?
- Through an equipment loan or lease secured by the van. At a representative 8%–30% APR, $100,000 across a few vans runs about $2,441–$3,601 a month over 48 months.
- Can I get a loan to buy an HVAC business?
- Yes. Business acquisitions are a standard use of SBA 7(a) loans, often combined with a seller note. Lenders look at the target's financials, its maintenance agreement base, and your experience in the trade.

Landon and Austin were greatLandon and Austin were great. Knowledgable and explained everything in a way that made it all really easy to understand. I avoid these call like the plague but these two were a joy to work with.
Highly recommendedHighly recommended! I worked with Corey, and he was awesome. He found an option after I received multiple rejections that no other company had presented to me. It was within my budget and my timeline. I'm so thankful!
BTC has become my go to for working…BTC has become my go to for working capital. Recently, my company was in a bind and needed funds. The BTC team, headed by Drew, took a problem solving approach and helped to overcome an initial denial, resulting in a better facility than the one I was turned down for. Thanks BTC! Thanks Drew!

How we ranked these options
This guide ranks types of financing, not individual lenders. Each option is ordered by how well it fits the need described on this page, judged on four things in this order: whether the structure matches how the money will be used and repaid, total cost, funding speed, and how hard it is to qualify. Cost figures are WithFunded calculations from published rate inputs as of November 2026: the bank prime loan rate from the Federal Reserve, the SBA maximum-rate schedule, and Federal Reserve survey data. The method follows our 2026 SMB Financing Cost Report, whose own figures use June 2026 rates.
WithFunded is a financing marketplace, not a lender. Our 2-minute form suggests a product type from the families we cover, and a funding partner reviews the request. Not every structure named in this guide is available through WithFunded: options such as SBA microloans, USDA farm loans, bank loans, and seller financing are ones you would pursue directly with the provider. They are listed because leaving out a good fit would make the ranking less useful.
