HVAC Financing Options Explained — $0 Down to 84-Month Plans

The Two Main Financing Paths

Most HVAC financing comes through dedicated home-improvement lenders — Synchrony Home, Wells Fargo Home Projects, GreenSky, Service Finance. We work with established partners and offer financing through them. The other path is a HELOC or home equity loan from your bank, which can offer lower interest rates but takes longer to close.

Common Offers You’ll See

$0 Down, 0% APR for 12–24 Months

The best offer if you can pay off the full balance in the promo window. After the promo, interest accrues at the standard rate (typically 24.99–29.99%) — and on most “deferred interest” plans, you’ll be charged interest from the original purchase date if you don’t pay it off in time. Read carefully.

$0 Down, Fixed-Rate Term Loans (60–84 Months)

Lower fixed rate (8.99–14.99% typical), predictable monthly payment. Better for buyers who can’t pay off the balance quickly. A $10,000 system at 9.99% over 84 months runs about $166/month.

$0 Down, Reduced Interest for Specific Equipment

Manufacturers (Carrier, Trane, Lennox) sometimes offer special rates on their high-efficiency equipment — e.g., 4.99% APR for 60 months on Infinity systems. We’ll show you these when applicable.

Who Qualifies?

For 0% promo plans: typically 700+ FICO score, stable income, debt-to-income ratio under 50%. For longer fixed-rate loans: 640+ FICO, stable income. For HELOCs: requires home equity (usually 15%+ above mortgage balance) and a higher credit score, but rates are lowest.

The Application Process

Online application takes 5 minutes. Soft credit pull, instant decision in most cases. If approved, you sign documents electronically, and we can install as soon as scheduled. The lender pays us directly; you pay the lender monthly.

What to Watch For

Other things to check:

• Prepayment penalty? Most home-improvement loans don’t have one, but verify before signing
• Origination fee? Some lenders charge 1–5% of the loan amount upfront
• Variable rate? Make sure it’s a fixed-rate loan unless you specifically want a variable line

Tax Credits That Reduce What You Finance

Federal tax credits up to $2,000 are available for high-efficiency heat pumps and central AC systems through 2032 (Inflation Reduction Act). State incentives vary. We’ll factor these into the total project cost so the financed amount is accurate.

How to Decide

If you can pay off the system in 12–24 months → go for the 0% promo plan, but pay it off in time.
If you need 5+ years to pay it off → fixed-rate term loan is safer than deferred interest.
If you have home equity and a good credit score → HELOC usually beats both, but takes 30–45 days to close.
