Flat rate pricing is the single biggest upgrade most HVAC companies can make to their business. Instead of quoting hourly rates and hoping customers don't flinch, you present a fixed price before the work starts. The customer knows what they're paying. Your techs know what to charge. Everyone wins.
Here's how to build a flat rate pricebook from scratch.
Why Flat Rate Beats Time & Materials
With time and materials (T&M), your fastest technicians make you the least money. A senior tech who fixes a compressor in 45 minutes bills less than a junior tech who takes 2 hours. That's backwards.
Flat rate flips this:
- Customers get price certainty — they approve the repair before you start
- Fast techs are rewarded — same price whether it takes 30 minutes or 90
- Revenue becomes predictable — you know your average ticket before the month ends
- Upselling happens naturally — Good/Better/Best options let customers choose
Step 1: List Every Service You Perform
Start with your most common repairs and services. Most HVAC companies perform 150-300 distinct tasks. Group them into categories:
- Diagnostics — service call fees, system evaluations
- AC Repairs — capacitors, contactors, fan motors, compressors, refrigerant
- Heating Repairs — ignitors, flame sensors, heat exchangers, gas valves
- Maintenance — tune-ups, filter changes, coil cleaning
- Installations — system replacements, new construction, ductwork
- Accessories — thermostats, UV lights, air purifiers, humidifiers
Don't try to list everything on day one. Start with your top 50 tasks — the ones that cover 80% of your service calls.
Step 2: Calculate Your True Cost Per Task
For each task, calculate:
| Component | Example (Capacitor Replacement) |
|---|---|
| Average labor time | 45 minutes |
| Labor cost (loaded rate) | $37.50 ($50/hr with burden) |
| Parts cost | $18 |
| Parts markup (50%) | $9 |
| Truck/overhead allocation | $25 |
| Total cost | $89.50 |
Your loaded labor rate includes wages, payroll taxes, benefits, workers comp, and vehicle costs. Most HVAC companies land between $40-65/hour loaded.
Step 3: Add Your Margin
Your flat rate price = Total Cost ÷ (1 - Target Margin)
For a 55% gross margin on that capacitor replacement:
$89.50 ÷ (1 - 0.55) = $198.89 → round to $199
Target margins by category:
- Diagnostics: 60-70% (high skill, low parts)
- Minor repairs: 50-60% (capacitors, contactors, ignitors)
- Major repairs: 45-55% (compressors, heat exchangers)
- Maintenance: 55-65% (routine, predictable)
- Installations: 35-45% (high parts cost, competitive)
Step 4: Build Good/Better/Best Options
For every service call, present three options:
| Option | Capacitor Failure Example | Price |
|---|---|---|
| Good | Replace capacitor | $199 |
| Better | Replace capacitor + full AC tune-up | $349 |
| Best | Replace capacitor + tune-up + maintenance agreement | $449 |
Most customers pick the middle option. This isn't upselling — it's giving customers informed choices. The "Best" option often includes a maintenance agreement that generates recurring revenue.
Step 5: Present Prices Professionally
A pricebook only works if your techs use it consistently. The presentation matters:
- Diagnose first — never quote a price before identifying the problem
- Show all three options — on a tablet or phone, not scribbled on paper
- Explain the value — "This option includes a maintenance agreement that catches problems before they become emergencies"
- Let the customer choose — don't pressure, don't recommend. Present and wait.
A digital pricebook (like the one in ServiceTap) makes this seamless. Your tech pulls up the task, the three options auto-generate with correct pricing, and the customer approves on-screen.
Step 6: Review and Adjust Quarterly
Your pricebook isn't set-and-forget. Review it every quarter:
- Check margins — are actual margins matching your targets?
- Update parts costs — supplier prices change constantly
- Add new tasks — every "one-off" that happens three times becomes a pricebook entry
- Adjust for competition — if you're losing bids on installations, your install prices may need work
Common Mistakes to Avoid
- Pricing too low — most first-time pricebook builders underprice by 15-20%
- Too many options — stick to three. More than that creates decision paralysis
- Not training techs — your pricebook is useless if techs don't use it
- Ignoring overhead — if you only price labor and parts, you're losing money on every call
