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.
The formula: Flat Rate = (Task Time × Shop Rate + Parts with Markup + Overhead) ÷ (1 − Target Margin). Your shop rate should already include your technician's burdened wage plus vehicle, tool, and training costs.
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.
