By BuildFolio Team · Last updated January 28, 2026
Flat rate pricing increases HVAC revenue 15-20% per service call. Learn how to build a flat rate book that protects your margins and gives customers the price certainty they want.
TL;DR — Quick Answer
Flat rate pricing charges a fixed price per repair task regardless of time. Formula: (average time x loaded labor rate) + materials + overhead + profit margin. HVAC companies using flat rate see 15-20% higher revenue per call. Build your book from actual job data, review quarterly, and present prices confidently.
Why Flat Rate Pricing Wins
Time-and-materials billing has three problems: customers hate open-ended pricing, fast techs earn less for being efficient, and every tech quotes differently. Flat rate solves all three.
| Factor | Hourly Pricing | Flat Rate Pricing |
|---|---|---|
| Customer experience | Anxious about the clock | Knows the price upfront |
| Tech incentive | Slower = more revenue | Faster = more jobs per day |
| Pricing consistency | Varies by tech | Same price every time |
| Revenue per call | Baseline | 15-20% higher on average |
| Profit predictability | Variable | Predictable per task |
How to Build Your Flat Rate Book
Step 1: List Your Top 50 Services
Start with the repairs and services you perform most often. Capacitor replacement, contactor replacement, blower motor, compressor diagnosis, refrigerant recharge, thermostat install, and so on. Cover 80% of your service calls first.
Step 2: Calculate Average Time per Task
Track how long each repair actually takes across multiple techs and jobs. Use the average, not the fastest or slowest. Include setup, diagnostic, repair, testing, and cleanup time.
Step 3: Apply the Flat Rate Formula
For each task:
- Labor cost: Average time (hours) x loaded labor rate ($42-$55/hr)
- Materials: Parts cost at your cost + markup (40-60%)
- Overhead allocation: Labor cost x overhead factor (0.35-0.45)
- Profit: Subtotal x profit margin (0.15-0.25)
- Round up: Round to nearest $5 or $10 for clean pricing
Example: Capacitor Replacement
| Average time | 0.75 hours |
| Loaded labor ($48/hr) | $36.00 |
| Parts (capacitor + markup) | $45.00 |
| Overhead (40% of labor) | $14.40 |
| Subtotal | $95.40 |
| Profit (20%) | $19.08 |
| Service call fee | $89.00 |
| Total flat rate price | $205.00 |

Common Flat Rate Mistakes
- Pricing too low to “ease into it” — start at your calculated rate, not a discounted rate
- Not including the service call fee — the diagnostic/trip charge is separate from the repair price
- Forgetting to update quarterly — parts prices change; review your book every 90 days
- Not training techs to present confidently — hesitation kills the sale more than high prices do
- Skipping the options — always offer repair vs. replace when applicable
Transitioning from Hourly to Flat Rate
Do not switch overnight. Start with your top 20 most common repairs. Train your techs on how to present flat rate prices. Use scripts: “The price for this repair is $385. That includes all parts, labor, and our warranty. Would you like to proceed?”
Track close rates and revenue per call for 90 days, then expand to your full service menu.

Frequently Asked Questions
What is flat rate pricing for HVAC?
Flat rate pricing means charging a fixed price per repair task regardless of time spent. Instead of billing $100/hr for however long a repair takes, you charge $385 for a capacitor replacement whether it takes 30 minutes or 90 minutes. This protects your margins on easy jobs and gives customers price certainty.
How do I calculate flat rate prices?
Start with average time to complete each task, multiply by your loaded labor rate, add materials cost, add overhead allocation (typically 35-45% of labor), and add your target profit margin (15-25%). Round to clean numbers. Review and adjust quarterly based on actual job data.
Does flat rate pricing increase revenue?
Yes. HVAC companies that switch to flat rate pricing typically see 15-20% higher revenue per service call. Customers prefer price certainty, techs are incentivized to work efficiently, and consistent pricing eliminates underbidding by junior techs.
