HVAC and home service credit card processing fees: how to lower them
HVAC, plumbing, electrical and other home-service businesses take payments in the field, by phone and by emailed invoice. Those keyed and card-not-present payments cost more than tap or dip, and on large tickets even a small markup becomes real money.

What's a normal effective rate for HVAC and home services?
As a typical estimate, home-service businesses with a lot of keyed or invoiced payments often see about 2.7–3.5% all-in. Because tickets are large, the processor's markup percentage matters more than the per-transaction fee.
Fees home-service businesses commonly overpay
- Markup on large tickets. A markup of a few tenths of a percent on a big system install adds up quickly. On interchange-plus plans, compare the markup line, not just the total.
- Keyed and card-not-present payments. Phone and manually entered payments carry higher card-network costs. Collect address verification (AVS) data and, where possible, tap or dip in the field.
- Invoice and payment-link fees layered on top of processing.
- Business and commercial cards, which often cost more. Ask whether your processor supports the data fields that can lower those costs.
- Junk fees such as PCI, statement, monthly minimum and account service fees.
Offering ACH or bank transfer for large invoices can also lower costs. See the effective rate guide to benchmark your statement.
