Flat rate pricing is the standard for profitable HVAC businesses. Instead of quoting hourly rates that make customers nervous, you give them a fixed price for the job before work begins. Customers love the transparency. You love the higher average tickets.
Here’s how to build a flat rate price book that protects your margins and grows your revenue.
Why Flat Rate Pricing Wins
For Customers:
- No surprise bills — they know the cost before you start
- Same price regardless of how long the job takes
- Feels fair and professional
- Easier to budget and approve
For Your Business:
- 15–25% higher average tickets compared to time-and-materials
- Faster estimates — tech looks up the price instead of calculating on the spot
- Consistent pricing across all technicians
- Eliminates disputes over “how long should this take?”
- Rewards efficiency — fast techs make you more money, not less
The Flat Rate Pricing Formula
Every flat rate price needs to cover four things:
Flat Rate Price = Parts Cost + Labor Cost + Overhead Allocation + Profit Margin1. Parts Cost
What you pay for the part + markup.
Industry standard markup: - Common parts (filters, capacitors, contactors): 100–200% markup - Major components (compressors, motors, coils): 50–100% markup - Equipment (furnaces, AC units, heat pumps): 30–50% markup
Example: You buy a capacitor for $15. At 150% markup, you sell it for $37.50.
2. Labor Cost
Your fully loaded hourly labor cost × estimated job time.
Fully loaded labor cost includes: - Technician hourly wage - Payroll taxes (7.65% employer FICA) - Workers’ comp insurance - Health benefits - Paid time off - Training time - Truck cost allocation
Example: Tech earns $30/hour. Fully loaded cost = ~$48/hour. Job takes 1.5 hours = $72 labor.
3. Overhead Allocation
Your monthly overhead ÷ monthly billable hours = overhead rate per hour.
Overhead includes: - Rent/mortgage - Insurance (GL, auto, umbrella) - Software subscriptions - Marketing - Office staff salaries - Vehicle maintenance - Utilities and phone
Example: $15,000/month overhead ÷ 600 billable hours = $25/hour overhead.
4. Profit Margin
Target: 15–25% net profit on service work, 8–15% on installations.
Building Your Price Book: Step by Step
Step 1: List All Services
Start with your 20 most common jobs: - AC diagnostic/service call - Thermostat replacement - Capacitor replacement - Contactor replacement - Blower motor replacement - Refrigerant recharge (per pound) - Drain line clearing - Filter replacement - Furnace ignitor replacement - Furnace inducer motor replacement - Evaporator coil cleaning - Condensate pump replacement - Circuit board replacement - Compressor replacement - AC system installation - Furnace installation - Heat pump installation - Duct repair - Duct sealing - Mini-split installation
Step 2: Calculate Each Price
For each service, calculate:
| Component | Capacitor Replacement Example |
|---|---|
| Parts (with markup) | $15 cost × 1.5 = $37.50 |
| Labor (1 hr × $48 loaded) | $48.00 |
| Overhead (1 hr × $25) | $25.00 |
| Subtotal | $110.50 |
| Profit margin (20%) | $22.10 |
| Flat Rate Price | $132.60 → Round to $135 |
Step 3: Research Market Rates
Your prices need to be competitive. Research what other HVAC companies in your area charge: - Call competitors for quotes - Check Angi and HomeAdvisor cost guides - Ask supply house reps what they see - Review industry benchmarks
Step 4: Create Tiered Options
For every job, offer “Good, Better, Best” options:
Example: AC Not Cooling — Capacitor Issue
| Option | Description | Price |
|---|---|---|
| Good | Replace capacitor, basic inspection | $135 |
| Better | Replace capacitor + full system tune-up | $285 |
| Best | Replace capacitor + tune-up + 1-year maintenance agreement | $420 |
Average customers choose the middle option. This increases your average ticket by 30–50%.
Step 5: Put It in Your Software
Load your entire price book into your field service software so technicians can look up prices on their phone and present options to customers instantly.
With Workloop, your technicians can pull up pricing, present options, and generate invoices all from the mobile app — right in front of the customer.

Common Pricing Mistakes
1. Pricing Too Low
New businesses often undercharge to win jobs. This leads to razor-thin margins, inability to hire, and eventual burnout. Price for profit, not for volume.
2. Not Updating Your Price Book
Parts costs, labor rates, and overhead change annually. Review and update your price book at least once per year — ideally quarterly.
3. Inconsistent Pricing
Without a price book, every tech quotes differently. Customer A pays $200 for a repair, Customer B pays $350 for the same thing. This kills trust and creates liability.
4. Forgetting Overhead
Many HVAC businesses only calculate parts + labor. They forget about insurance, trucks, marketing, software, and training. When you forget overhead, every “profitable” job is actually losing money.
5. Not Offering Options
Giving customers a single price is leaving money on the table. Always present 2–3 options. The “Best” option should feel like great value compared to the “Good” option.
FAQ
What’s the average HVAC profit margin?
Healthy HVAC businesses target 15–25% net profit on service work and 8–15% on installations. Top performers hit 30%+ on service.
Should I charge a diagnostic fee?
Yes. A diagnostic/service call fee ($89–$150) covers your cost to show up. Most companies waive it if the customer proceeds with the repair — this incentivizes booking work.
How often should I update my HVAC price book?
At minimum annually, ideally quarterly. Parts costs fluctuate, especially with supply chain changes. If your profit margins are shrinking, your prices need to catch up.
What’s better: flat rate or time and materials?
Flat rate is better for residential service. Customers prefer predictable pricing, and your average tickets will be 15–25% higher. Time and materials may work for large commercial projects where scope is uncertain.
