HVAC financing usually comes from dealer 0% card offers, personal loans, home equity, or utility and government loan programs. In 2026, Carrier and Trane dealers advertise 0% APR for 60 months on approved credit, while the average 24-month personal loan at banks was 11.90% in August 2026.
Information checked on November 4, 2026. This guide explains how the options work; it isn’t financial advice, so compare the offers you receive with a trusted advisor if you’re unsure.
HVAC financing options compared
| Option | Typical cost in 2026 | Watch out for |
|---|---|---|
| Dealer 0% card offer | 0% APR for 60 months on approved credit (Carrier, Trane); 28.99% standard purchase APR | Expiration dates and dealer fees built into the price |
| Deferred-interest promotion | No interest only if paid in full on time | Interest back to the purchase date if you don’t |
| Personal loan | 11.90% average for 24 months at banks (August 2026) | Origination fees and credit-based pricing |
| Credit card | 22.36% average on accounts charged interest (August 2026) | The highest cost if you carry a balance |
| Home equity loan or HELOC | Varies by lender | Your home is the collateral |
| FHA Title I loan | Fixed rate set with a HUD-approved lender | A mortgage lien on loans over $7,500 |
| Utility or state loan | For example, 0% up to $25,000 (Mass Save HEAT Loan) | Only in program areas and for approved upgrades |
| PACE financing | Interest around 7% to 8%, per the CFPB | A lien that ranks ahead of your mortgage |
| Lease-to-own | Lease payments, not a loan | The total of all payments |
How 0% HVAC financing offers work
Both Carrier and Trane list 0% APR for 60 months through a Wells Fargo credit card, available through participating dealers. In these plans, the monthly payment is the amount that pays off the purchase in equal payments during the promotional period. For instance, both brands show $10,000 over 60 months at about $167 a month.
However, these offers expire. Carrier’s offer runs until November 20, 2026, and Trane’s until December 31, 2026. In addition, the standard purchase APR on both cards is 28.99% for new accounts, so any purchase outside the promotion costs far more.
Credit matters too. Trane says that, in general, you need a credit score of 670 or higher. Meanwhile, Carrier says its financing can be combined with its Cool Cash rebate of up to $2,100, but only when a Carrier Factory Authorized Dealer installs the equipment.
Deferred interest: the catch in “no interest if paid in full”
Some promotions don’t charge 0% interest; instead, they defer it. According to the CFPB, you pay no interest only if you pay off the purchase within the promotional period. Otherwise, you could owe all the interest back to the original date of the charge.
Being more than 60 days late on a payment can also cancel the deferred period, the CFPB warns. Moreover, the minimum payment probably won’t pay off the balance in time. So divide the balance by the number of months yourself, and pay at least that much.
Dealer fees can raise the price
Trane’s own financing FAQ says an HVAC company “may raise the overall cost of HVAC replacement due to dealer’s fees, origination fees, and more.” Therefore, ask every contractor for the cash price and the financed price in writing, and compare them.
Personal loans and credit cards for HVAC financing
A personal loan gives you cash, so you can pay the contractor as a cash buyer. According to the Federal Reserve, banks charged an average of 11.90% on 24-month personal loans in August 2026. By contrast, credit card plans averaged 22.36% on accounts that paid interest.
| $10,000 over 24 months | Monthly payment | Total interest |
|---|---|---|
| Personal loan at 11.90% | $470 | $1,286 |
| Credit card at 22.36% | $521 | $2,493 |
| 0% equal-payment promotion | $417 | $0 |
As the table shows, a true 0% plan saves the most if you can make the payments. However, a personal loan can still win if the dealer charges more for financed jobs, so compare the total cost.
Government and utility HVAC financing
- FHA Title I loans: HUD insures loans made by approved private lenders, such as banks and credit unions. For a single-family house, the maximum is $25,000 over up to 20 years, at a fixed rate with no prepayment penalty. Any loan over $7,500 must be secured by a mortgage or deed of trust.
- Utility loans: some utilities offer low-interest loans. Mass Save’s HEAT Loan, for example, offers 0% financing of up to $25,000 for qualified improvements in Massachusetts.
- HOMES rebates paid to a lender: since May 2026, DOE lets homeowners direct a HOMES rebate to an aggregator, such as a third-party lender, where their state allows it.
Before you borrow, also check the rebates you can get, since they lower the amount you need to finance. Our guides to heat pump rebates and the HEAR rebate program list what’s available in 2026.
PACE financing: read the fine print
Property Assessed Clean Energy (PACE) financing is repaid through your property tax bill, and it’s secured by a lien on your home. According to the CFPB, these liens usually rank ahead of your mortgage, even one that came first. As a result, the debt stays with the house if you sell, unless you pay it off.
The CFPB also found that PACE loans raised property tax bills by about $2,700 a year on average. In addition, Fannie Mae and Freddie Mac generally won’t buy mortgages on homes with first-lien PACE debt. Since March 1, 2026, however, a CFPB rule requires PACE lenders to check your ability to repay.
How to choose HVAC financing
- First of all, get at least three quotes, each with a cash price and a financed price.
- Then subtract every rebate you qualify for, so you finance only what’s left.
- Next, check your credit score, since Trane’s 0% offer, for example, generally needs 670 or higher.
- After that, compare the APR and the total cost of every option, not just the monthly payment.
- Read whether a promotion is true 0% APR or deferred interest, and note the end date.
- Finally, avoid financing that puts a lien ahead of your mortgage unless you fully understand the risks.
If your system still works, it may pay to repair it while you compare offers. Our repair or replace guide and our heat pump cost guide can help you set a budget.

HVAC financing FAQ
What credit score do I need for HVAC financing?
It depends on the lender. For its 0% offer, Trane says you’ll generally need a score of 670 or higher. With a lower score, you may still qualify for a personal loan, although at a higher rate.
Is 0% HVAC financing really free?
It can be, if it’s a true 0% APR plan and you pay on time. Even so, dealer fees may raise the price, and deferred-interest plans can charge interest back to the purchase date. So compare the financed price with the cash price.
Can I finance a heat pump with bad credit?
Sometimes. Carrier, for example, mentions a lease-to-own option through Microf for people with lower credit scores. However, a lease isn’t a loan, so add up all the payments before you sign.
Can I combine HVAC financing with rebates?
It depends on the program. For instance, Carrier allows its financing with its Cool Cash rebate when a Factory Authorized Dealer installs the system. Still, check each program’s rules.
