Bookkeeping and CFO services for HVAC companies

Your technicians are busy. But are your service calls profitable?

HVAC profitability depends on more than keeping technicians scheduled. Labor burden, travel time, callbacks, equipment costs, seasonal demand, and pricing all affect what your business actually earns.

We help HVAC owners understand service profitability, installation margins, and the financial impact of their operational decisions.

The financial challenges behind the work

  • Underestimating the true cost of technician laborIf rates are built on the wage alone, every hour sold is underpriced before overhead enters the picture.
  • Service pricing that doesn’t cover overheadTrucks, dispatch, office staff and insurance have to be paid from service revenue. Prices that miss them shrink profit as volume grows.
  • Unprofitable installation projectsA large install can look like a big win while equipment costs, extra labor and callbacks erase the margin.
  • Seasonal cash flow fluctuationsPeak months bring cash in; shoulder months still carry full payroll and fixed costs.
  • Callback and warranty expensesReturn trips are paid labor and parts with no new revenue. Untracked, they hide inside other costs.
  • Maintenance agreements priced without knowing delivery costsAn agreement priced below the cost of the visits it promises loses money on every renewal.

The numbers that matter

These are the measures that tell HVAC owners the most about how the business is really doing.

Fully burdened technician cost

What it measures: Wages plus employer payroll taxes, benefits, insurance and other employment costs.

Why it matters: It’s the starting point for any service rate that actually covers labor.

Revenue per billable hour

What it measures: Revenue generated relative to actual billable technician hours.

Why it matters: Shows whether your pricing and utilization keep pace with labor costs.

Gross margin by service type

What it measures: How service, installation and maintenance work each perform.

Why it matters: Tells you where to focus sales effort and which line needs a pricing review.

Callback costs

What it measures: Labor and materials spent correcting previous work.

Why it matters: Highlights training or quality issues and the real cost of warranty work.

Maintenance agreement profitability

What it measures: Agreement revenue compared with the cost of fulfilling the service obligations.

Why it matters: Confirms your agreements are building profit, not just volume.

What does a $30-per-hour technician actually cost?

Hypothetical illustration—not a client result and not a guarantee of results.

Base hourly wage$30
Illustrative employer taxes and benefits$9
Illustrative other employment-related costs$6
Total illustrative hourly employment cost$45
Paid hours per week40
Weekly employment cost$1,800
Billable hours per week30
Employment cost per billable hour$60

$45 × 40 paid hours = $1,800 a week. $1,800 ÷ 30 billable hours = $60 per billable hour.

All figures are hypothetical. Your costs depend on your wages, benefits, insurance and how many hours your technicians bill.

The business lesson

A technician earning $30 an hour can represent $60 in employment cost per billable hour before vehicle costs, parts, company overhead and profit. That’s why billable utilization and labor burden belong at the center of how you set service rates.

How AM Financial helps

Your financial information should help you evaluate technician costs, service profitability, installation margins, and the financial impact of seasonal demand.

  • Bookkeeping for contractors: Monthly financial reporting that keeps labor, equipment and overhead in the right categories, so margins are reliable.
  • Job-profitability reporting: Report service, installation and maintenance work separately so you can see which line carries the business.
  • Cash flow planning: Plan payroll and equipment purchases around the peak and shoulder seasons with a monthly cash outlook.
  • CFO services: Work through pricing, staffing and maintenance-agreement decisions with your actual cost per technician hour.

Monthly bookkeeping is included in every package. Job-profitability reporting and a monthly cash outlook are part of Profit & Cash Flow and above. Budgeting, forecasting and decision analysis are part of Strategic CFO Partnership. Cleanup, initial job-costing setup and financial operations support (such as payroll, invoicing or advanced construction reporting) are scoped separately. Your written proposal spells out exactly what’s included.

What working together looks like

What we review

To build an accurate picture of the business, we typically review:

  • Payroll reports and technician hours, including billable time
  • Revenue by type of work: service, installation and maintenance
  • Equipment and parts purchases, and warranty or callback work
  • Maintenance agreement revenue and the visits it requires

We work from your accounting software, bank and credit card activity, and the records your team already produces. Documents are shared through our secure client portal or a shared folder, and you don’t have to change field or estimating software to get started.

Reporting you may receive

Depending on your package and agreed scope, reporting for your business can include:

  • Install versus service margins, reported separately
  • Maintenance-agreement revenue tracked on its own
  • A monthly cash outlook covering peak and shoulder seasons

How it supports your decisions

Together, these reports help you set rates that cover your real labor cost, decide when another technician will pay for themselves, and prepare cash for the slower months. We walk through the numbers with you in plain English at your agreed review meetings.

Questions HVAC owners ask

How do I calculate the true cost of an HVAC technician?

Add wages, employer payroll taxes, workers’ comp, benefits and other employment costs for the year, then divide by the hours the technician actually bills, not the hours they’re paid. Our labor burden calculator walks through it.

Why is my HVAC company busy but not profitable?

Common causes are rates built on wages instead of fully burdened labor, low billable utilization, underpriced installs or agreements, and callbacks. Margin reporting by type of work usually shows which one is the problem.

How should I compare installation and service profitability?

Track revenue and direct costs for each line separately: equipment, labor and materials for installs; labor, parts and travel for service. Comparing gross margin side by side shows which work is carrying the business.

How can I prepare for seasonal cash flow changes?

A monthly cash outlook compares expected receipts with payroll, bills and planned purchases, so you can build a reserve in peak months and see a tight month coming before it arrives.

How do I know whether maintenance agreements are profitable?

Track agreement revenue on its own and compare it with the labor, materials and travel time spent on agreement visits. Repair and replacement work that comes from agreement customers is worth tracking separately.
