  • Use this calculator to build data-backed flat rate entries for your price book.

How HVAC Flat Rate Pricing Works

Flat rate pricing gives the customer a fixed price before the work starts. The technician looks up the task in the price book, quotes the number, and gets approval. No open-ended hourly billing, no surprises.

Your shop rate should already include your technician's burdened wage plus vehicle, tool, and training costs.

HVAC Flat Rate Price Formula

Flat Rate Price = (Task Time × Shop Labor Rate + Parts Cost × (1 + Markup %) + Overhead) ÷ (1 − Target Gross Margin)

For example: 1.5 hours × $95/hr shop rate = $142.50 labor. $45 parts at 50% markup = $67.50. $15 overhead. Total cost = $225. At 65% target margin: $225 ÷ 0.35 = $643 flat rate price.

HVAC Flat Rate Price vs Service Call Fee

A service call fee covers the cost of showing up, diagnosing the issue, and rolling a truck. A flat rate repair price covers the actual repair task, including labor, parts, overhead, and profit. Many HVAC companies charge a service call fee first, then quote a flat rate repair after diagnosis.

Use the HVAC service call fee calculator to set your trip/diagnostic charge, and this flat rate calculator to price the repair tasks in your price book.

HVAC Flat Rate Pricing FAQs

How do I calculate HVAC flat rate prices?▼
Start with estimated task time multiplied by your shop labor rate, add parts with your standard markup, include an overhead allocation, then divide by (1 minus your target margin). For example: 1.5 hrs × $125 + $67.50 parts = $255 cost → $255 ÷ 0.35 = $728 flat rate at 65% margin.
What is a good gross margin for HVAC flat rates?▼
Most HVAC contractors target 60–70% gross margin on flat rate tasks. Below 55% usually indicates that labor rates or parts markup are too low.
Should HVAC technicians quote flat rate or hourly?▼
Flat rate is preferred for residential service work because customers want price certainty. Hourly billing is sometimes used for commercial contracts with defined scope, but even commercial work increasingly uses flat rate for standard tasks.
How much should I mark up HVAC parts?▼
Most HVAC companies mark up parts 40–100% depending on the part category. Small consumables often get higher markup percentages; expensive equipment gets lower percentage but higher dollar margin.
How often should I update my HVAC price book?▼
Review your price book at least annually, or whenever supplier pricing changes significantly. Many contractors do a mid-year adjustment for parts costs and an annual adjustment for labor rates.
