How we make money: The Business Funding Club is a referral service, not a lender and not a broker. We refer businesses that ask for capital to ROK Financial. ROK and the lenders it matches you with make every funding decision. ROK pays us when a business we refer receives funding. It is free to you, and nothing here is an offer of credit. Read the full disclosure.

For HVAC contractors

You stock the units and staff the vans before the heat wave. The money comes in after the systems are running.

An HVAC shop buys equipment, refrigerant and van time ahead of two peak seasons, then gets paid job by job, and on commercial work, month by month with retainage held. The Business Funding Club is a free referral club, not a lender. We send HVAC contractors to ROK Financial. ROK and the lenders it matches you with review each request and make every funding decision.

The math

The math

  1. SHOULDER SEASON

    You stock up and hire

    Condensers, air handlers, coils and refrigerant go on the shelf before the calls come. New hires need EPA refrigerant handling certification, which nearly all HVAC technicians must hold[1].

  2. PEAK SEASON

    You run every van

    Technicians may work overtime or irregular schedules during peak heating and cooling seasons[1]. Payroll, fuel and parts go out every week.

  3. JOB BY JOB

    You get paid

    For example, a homeowner changeout is invoiced once the system runs. A federal fixed-price construction job bills monthly as work proceeds, and retainage can be held if progress is not satisfactory[2].

Nothing here means the shop is in trouble. HVAC work bunches into two seasons and is paid after it is done. The more systems you sell in July, the more inventory and payroll you carried in May. That is a growth problem, not a rescue.

First: this is financing for the HVAC business, not for homeowners

Searching "hvac financing"?

Most people who search that phrase are homeowners looking to pay for a new system. This page is about financing the HVAC company itself: its vans, tools, equipment inventory and payroll. ROK Financial does not offer consumer financing for your customers, and neither does the Club. For general contractor cash flow, see our construction page.

Two peaks a year, and the crew you need for them

HVAC work peaks in the heating and cooling seasons, when technicians may be on call for emergencies and work overtime[1]. In the shoulder months the calls slow down. Your van notes, shop rent and the technicians you want to keep do not.

Hiring ahead of the peak costs money. The Bureau of Labor Statistics projects about 40,600 HVAC mechanic and installer openings a year over the decade, and the median annual wage was $61,010 in May 2025[1].

Certification is part of the hire. Under Section 608 of the Clean Air Act, technicians who maintain, service, repair or dispose of equipment that could release ozone-depleting refrigerants must be certified[3]. Only EPA-certified technicians, or employers with written proof they employ at least one, may buy restricted refrigerant in cylinders, cans or drums, with limited exceptions[4].

Refrigerant rules and efficiency standards change what sits on your shelf

The AIM Act lets EPA phase down HFCs and restrict them sector by sector[5]. Under the 2023 rule, residential and light commercial AC systems using refrigerants such as R-410A could be installed only until January 1, 2026, and EPA noted that major manufacturers had moved to R-454B, which has seen shortages and stockpiling[6].

In a rule finalized May 21, 2026, EPA removed that installation date for residential and light commercial AC and heat pump equipment manufactured or imported before January 1, 2025, and allowed that inventory to be installed until supply runs out[7].

DOE's central air conditioner standards took effect January 1, 2023. In the Southeast and Southwest, split-system air conditioners installed on or after that date must meet the new regional standards[8].

Each change moves cash: two product lines on the shelf, refrigerant bought ahead of a shortage, recovery gear for a new refrigerant. All of it is paid before a customer pays.

Vans, tools, and the commercial jobs that pay in pieces

Each technician needs a stocked service van, a recovery machine, gauges and a vacuum pump. Adding a technician usually means adding a van. Ask your tax preparer about Section 179, which lets a business elect to deduct eligible property in the year it is placed in service, within IRS limits[9].

Commercial work pays differently. On a federal fixed-price construction contract, progress payments are made monthly as the work proceeds, and the owner can hold up to 10 percent of a payment if progress is not satisfactory[2]. As a mechanical sub, your money also passes through the general contractor; our construction page covers retainage and pay-when-paid rules.

For example: a shop replaces rooftop units on a school during summer service season. Units, crane time and crew are paid up front. The school pays monthly with part held until closeout, and the service side still needs inventory every week.

What ROK will want to see from an HVAC company

ROK's partner application lists at least 4 months in business and at least $10,000 in monthly gross sales, which is $120,000 a year[10]. Lenders commonly look at credit history, cash flow, equity and collateral[11]. Credit is one input among several. Have these ready:

  • Twelve months of business bank statements, so the seasonal swing is visible.
  • Your state HVAC or mechanical contractor license and proof of insurance.
  • For a van or equipment: the quote with make, model and year, or VIN.
  • For commercial jobs: contracts, pay applications, and a receivables aging with retainage on its own line.
  • Current debts, including van and equipment notes.

These are what lenders commonly review. ROK and its lenders decide what they need and whether to fund. The Club does not.

Financing that fits this kind of gap

Which one fits your business, if any, is a conversation to have with ROK’s advisor once they have seen your file. These are the types that usually come up.

Common questions

Does this page offer HVAC financing for homeowners?

No. Many people searching "hvac financing" want to pay for a system at home. This page is about financing the HVAC business itself: vans, tools, equipment inventory and payroll. ROK Financial does not offer consumer financing for your customers, and The Business Funding Club does not either.

What do lenders look at for HVAC business loans?

Lenders commonly look at credit history, cash flow, equity and collateral[11]. For an HVAC company, a full year of bank statements shows both peaks honestly. Add your license, insurance, equipment quotes and commercial contracts. ROK's partner application lists at least 4 months in business and $10,000 in monthly gross sales[10].

Can I finance service vans and HVAC equipment?

Equipment financing is usually the closest fit for vans, recovery machines and tools you will use for years. ROK describes it as a loan or lease for almost any tangible business asset[13]. Bring the quote with make, model and year, and ask your tax preparer about Section 179[9]. ROK and its lenders decide.

How do the refrigerant changes affect my cash?

They change what you stock. The 2023 EPA rule set January 1, 2026 as the last install date for residential systems using refrigerants such as R-410A[6]. A rule finalized May 21, 2026 removed that date for equipment made or imported before 2025[7]. Two product lines, or refrigerant bought ahead of a shortage, ties up cash before customers pay.

What does The Business Funding Club cost?

Nothing. The Business Funding Club is a free referral club, not a lender and not a broker. We send your application to ROK Financial. ROK and the lenders it matches you with review it and make every funding decision. If your business is funded, ROK pays us a referral commission. You never pay the Club anything.
