Finance or pay cash?

You're looking at a $20,000 HVAC quote and wondering whether it's smarter to write a check or finance the whole thing at $180/month. The answer isn't the same for everyone. Here's the math, laid out honestly.

The two financing paths in Florida

NewHVACDeals works with two lenders, and most Florida HVAC companies work with some version of these same two:

Both lenders run soft credit checks for pre-qualification, so checking your rate doesn't affect your credit score. Both process funds directly to the contractor at install, and both are regulated by the CFPB.

The actual math on a $20,000 system

A 120-month financing term costs about $9,000 in interest on a $20,000 system. If you could instead invest that $20,000 at 7% average annual return, it would grow to ~$39,300 over the same 10 years — a net advantage of roughly $10,000 by financing. But that only works if you actually invest the lump sum instead of spending it on something else.

When to pay cash

• You already have a fully-funded emergency fund and aren't carrying higher-rate debt
• Your alternative savings yield is below the financing APR (e.g. cash sitting in a checking account earning 0%)
• You're retired on a fixed income and dislike ongoing payments for psychological reasons
• You have a tax year where the full cash outlay gives you a meaningful deduction (uncommon for residential HVAC)

When to finance

• You'd otherwise drain your emergency fund or hit a credit card at 22% APR
• You're investing consistently and have the discipline to keep doing it with the cash you'd have spent
• You're a few years from selling the home and want to spread the cost over the time you live there
• You want the 48-hour swap window on our deposit reservation without committing the full amount before install day

Our default recommendation

We think most Florida homeowners in 2026 should reserve with our $500 refundable deposit, then pick a financing plan at install time based on what their cash situation looks like that week. The deposit model means you don't have to decide today — you can change your mind at any point before the crew arrives, with a full refund. That's the whole reason we built it this way.
