APU Financing: What to Compare Before You Sign

A practical guide to comparing quotes, total cost, installation, warranty and cash flow before financing an APU. Go Green APU lists two official application paths.

Update note (July 20, 2026): this guide was revised to remove payment, down-payment, APR and credit-score claims that are not published on the official financing page. Confirm every offer directly with the provider before signing.

Financing an APU is a cash-flow decision

An APU can help keep the cab comfortable and power auxiliary equipment without continuously relying on the main engine. For an owner-operator, however, the useful question is not only what the equipment costs. It is what the unit will cost to own, install, maintain and finance over the entire agreement.

Go Green APU's official financing page lists two application paths, one through QuickSpark and another through SLS Financial. The company also publishes 814-942-9407 for questions. The page does not publish one universal rate, monthly payment, down payment or minimum credit score, so treat those terms as unknown until you receive a written offer.

The six numbers to request in writing

Before comparing offers, ask for a quote that separates:

• APU price: identify the exact model and whether it is new, rebuilt or used.
• Installation: confirm whether labor, brackets, wiring, hoses and testing are included.
• Down payment and upfront charges: know how much cash is due before the truck is returned.
• Payment, term and frequency: verify the total number of payments and the first due date.
• APR and finance charge: do not compare the monthly payment alone; a longer term can lower the payment while raising total cost.
• Total contract cost: add the down payment, scheduled payments, documentation charges and any final payment.

Use this simple formula: scheduled total cost = down payment + all payments + fees + final payment. If the offer is a lease, separately ask what happens at the end: return, purchase, renewal or a residual payment.

What installation should include

Installation affects both the real cost and the truck's downtime. Ask the work order to specify the mounting location, fuel connection, electrical system, heat or air-conditioning work, load testing and any modification required on the truck.

Also confirm who is responsible if a leak, electrical fault or mounting problem appears after delivery. Equipment and labor warranties may have different providers, durations and exclusions. If the quote does not explain them, request clarification before authorizing the work.

Run the numbers with your data, not a generic promise

Potential savings depend on your actual idling hours, climate, routes, fuel price, maintenance and operating pattern. Review at least 30 days of fuel records and estimate how many main-engine hours you could realistically replace.

Then calculate: monthly operating benefit = avoided idling cost minus APU fuel and maintenance minus the monthly payment. Build a conservative case, a likely case and a demanding case. If the agreement works only in the most optimistic scenario, the obligation may be too tight during slow months.

Contract and risk questions

• Is the rate fixed for the entire term?
• Is there a prepayment penalty?
• What late, return or documentation charges apply?
• Will the lender file a UCC lien or another lien on the equipment or business?
• What insurance does the finance provider require?
• Can the agreement transfer if you sell the truck?
• What happens if the truck is out of service or declared a total loss?
• Does the warranty remain in force for the full finance term?

Do not sign a blank application or rely on phone promises that do not appear in the contract. Keep copies of the quote, payment schedule, installation order and warranties.

New, rebuilt or used

A lower price does not always produce the lowest total cost. For a used or rebuilt APU, ask about hours, replaced parts, coverage, service availability and exclusions. For a new unit, confirm when the warranty begins and whether documented maintenance is required.

Before committing capital, consider the condition of the truck that will receive the equipment. A mechanical inspection may identify electrical, fuel or mounting needs. You can review services from The Truck Savers, but evaluate the inspection and the financing decision separately.

How to apply and compare without rushing

1. Define the model and installation scope.
2. Request written terms through more than one path when possible.
3. Compare total cost, not only an advertised payment.
4. Calculate the impact with your own operating records.
5. Confirm warranty, service, insurance and end-of-term options.
6. Sign only when the agreement matches the quote.
