Bank Statement Analysis for HVAC and Plumbing Contractors

Trade Contractors: Service Revenue Meets Seasonal Installs

HVAC and plumbing companies have two distinct revenue engines: steady year-round service and repair calls, plus large seasonal installation projects. The mix produces a bank statement with a recurring base and sharp seasonal peaks.

How Revenue Appears

• Card and ACH service payments: Frequent small-to-mid deposits from repair calls and maintenance plans.
• Install project deposits: Large lump sums for system replacements, often with a deposit-then-completion structure.
• Maintenance-agreement billing: Recurring seasonal tune-up plans — a recurring-revenue signal lenders like.
• Supplier and payroll outflows: Equipment purchases ahead of installs create a working-capital gap.

Seasonality Lenders Must Expect

HVAC peaks in summer (AC) and winter (heating), with shoulder-season dips in spring and fall. Plumbing is steadier but spikes with freeze events. A 12-month view is essential — judging an HVAC firm by an April statement understates a business that earns most of its money in July and January.

What Lenders Focus On

• Recurring service revenue as the stable base
• Maintenance-agreement billing as a quality indicator
• Working-capital gap between equipment purchase and customer payment
• NSF events around large supplier outflows

Bottom Line

Trade contractors are strong borrowers for working capital and equipment lines. Reading them well means averaging across seasons and recognizing the service base beneath the install spikes — exactly what StatementScrub automates.
