General information, not legal advice.

Explain service agreements separately from completed calls

Track agreement receipts, covered visits and remaining commitments using the accounting method your CPA approves. Keep this schedule distinct from one-time repairs so a strong month of renewals does not obscure the cost of future service.

Match equipment purchases to installations

Supplier invoices, delivery charges and credits should carry the installation job reference. HVAC bookkeeping can then distinguish equipment committed to a customer job from parts kept for general service work.

Bring technician assignments into HVAC payroll

Approved time should identify the jobs and service calls each technician supported. Keep callbacks and warranty visits visible so their labor cost is not mistaken for a new billable installation.

Preserve field detail for public building retrofits

On covered California public work, retain the actual tasks and project assignments behind each employee’s hours. Those records support prevailing wage review and certified payroll preparation. Tidwell can help with DIR submissions after the project requirements and payroll inputs are established.

Service-agreement and technician-cost questions

How does HVAC bookkeeping handle prepaid maintenance?

Maintain a schedule of receipts and service activity using the recognition method directed by your CPA. The bank deposit alone does not explain the remaining commitment.

Can payroll costs distinguish callbacks from new work?

Yes. Approved time coded to callbacks or warranty work keeps that labor visible in operating reports.

What should an HVAC contractor bring for certified payroll setup?

Bring project instructions, approved worker time, task descriptions and existing payroll information so the reporting scope can be reviewed.
