How to Build an HVAC Flat Rate Pricing Book (With Examples)

An HVAC flat rate pricing book is the single most profitable tool most contractors never build. Instead, they quote every job off the top of their head — or worse, let their techs wing it in the field. The result is inconsistent pricing, margin leakage, and customers who sense you're making up numbers.

A proper price book fixes all of that. Here's how to build one from scratch, keep it updated, and actually get your team to use it.

Why You Need a Flat Rate Pricing Book

If you're still quoting HVAC work on time-and-materials for every call, you're leaving money on the table. Here's what happens without a price book:

Your senior tech quotes $850 for a capacitor replacement. Your junior tech quotes $475 for the same job at the next house. The customer who got the $850 quote checks Google reviews, sees the inconsistency, and calls your competitor instead.

A flat rate pricing book eliminates this. Every tech quotes the same price for the same work, every time. The benefits compound fast: faster quoting in the field, consistent margins across your team, easier training for new hires, and customers who trust your pricing because it feels professional and standardized.

The Anatomy of a Price Book Entry

Every entry in your flat rate book needs four components on the backend. Your techs only see the final price, but you need to calculate each piece to make sure the math works.

1. Material Cost

This is your actual cost for parts, equipment, refrigerant, and supplies. Use your current distributor pricing, not list price. If you're buying a TXV valve from your supply house for $85, that's your material cost — not the $140 retail price.

Pro tip: Build your price book using the cost from your primary distributor, not the cheapest price you've ever found. You want margins that hold up even when you can't get the preferred pricing on a specific day.

2. Labor Cost (Fully Loaded)

This is where most contractors mess up. Your labor cost isn't just what you pay the tech per hour. It's the fully loaded rate: wages, payroll taxes, workers' comp, health insurance, vehicle cost, tools, uniforms, and training time.

For most HVAC companies, the fully loaded cost of a technician is 1.5x to 2x their hourly wage. A tech making $30/hour actually costs you $45-$60/hour when you factor everything in.

Multiply your fully loaded rate by the average time to complete the task. Be honest about this — time your techs on real jobs, don't guess. If a condenser fan motor replacement takes your average tech 1.5 hours including drive time, setup, and cleanup, use 1.5 hours.

3. Overhead Allocation

Your overhead — rent, office staff, insurance, marketing, software, phones — doesn't disappear just because you're pricing individual jobs. You need to spread it across your revenue.

The simplest method: take your total monthly overhead and divide it by the number of jobs you run per month. If your overhead is $15,000/month and you run 200 jobs, that's $75 per job in overhead allocation.

Some contractors get more granular and allocate overhead as a percentage of labor. Either method works — the important thing is that overhead is in the price, not ignored.

4. Profit Margin

After materials, labor, and overhead, you add your profit margin. This is the money that actually grows your business — covers your salary as the owner, builds reserves, and funds expansion.

Most successful HVAC companies target 55-65% gross margin on labor-heavy services (diagnostics, repairs) and 25-35% markup on equipment-heavy installs where the material cost is a larger share of the total.

The pricing formula:

Flat Rate Price = (Materials + Labor + Overhead) ÷ (1 - Target Gross Margin)

Example: A capacitor replacement costs you $25 in materials, $90 in labor (1.5 hours × $60 fully loaded), and $75 in overhead. Your total cost is $190. At a 60% gross margin target:

$190 ÷ (1 - 0.60) = $190 ÷ 0.40 = $475 flat rate price

How to Organize Your Price Book

Structure matters. A price book nobody can navigate is a price book nobody uses. Organize by service category, then by specific task within each category.

Recommended Categories

Diagnostics & Service Calls — Your bread-and-butter calls. Diagnostic fee, trip charges, after-hours premiums. These are high-margin, low-material jobs. Price them accordingly.

Repairs by Component — Organize by the component being replaced or repaired: capacitors, contactors, fan motors, compressors, control boards, thermostats, TXV valves, coils. Within each component, have separate line items for common equipment types (rooftop unit vs. split system, for example).

Maintenance & Tune-Ups — Seasonal maintenance pricing by system type and size. Include your maintenance agreement pricing here too, with per-visit and annual rates.

Installations — New system installs by equipment type, size (tonnage), and complexity level (standard, moderate, complex). Installs have thinner margins but higher dollar amounts, so accuracy matters more here than anywhere else.

Indoor Air Quality — Duct cleaning, UV light installation, air purifier installation, humidifier and dehumidifier installs. This is a growing category with strong margins.

Add-Ons and Upgrades — Thermostat upgrades, surge protectors, drain line safety switches, condensate pumps. These are your upsell items — small ticket, high margin, easy for techs to offer on every call.

Task Codes

Assign every line item a code. Something simple like RPR-CAP-01 for "Repair — Capacitor — Standard" works. Task codes make it faster for techs to find the right price, easier for your office to process invoices, and simpler to track which services generate the most revenue.

Getting Your Team to Actually Use It

The best price book in the world is worthless if your techs ignore it. Here's what works:

Make it accessible. Your price book needs to be on your techs' phones or tablets, not in a binder in the truck. If they have to dig for it, they'll skip it and quote from memory. Software that puts your price book in a mobile app — like PropertyHQ's estimating tools — makes this seamless.

Train on the "why." Don't just hand over prices and say "use these." Explain how the prices were calculated, why consistent pricing matters, and how it protects both the company and the tech. When techs understand the margin math, they stop discounting in the field.

Remove discounting authority. Your techs should not be able to adjust prices without manager approval. Period. If a customer pushes back, the tech calls the office. The moment you let field techs negotiate pricing, your margins start eroding.

Review performance monthly. Track which techs are closing at book rate and which are requesting discounts constantly. If one tech is always asking for lower prices, they need sales training — not cheaper prices.

When to Update Your Price Book

A stale price book is almost as bad as no price book. Equipment costs change, labor rates shift, and your overhead evolves as you grow. Plan for regular updates:

Twice a year minimum — Before cooling season (March/April) and before heating season (September/October). Adjust for any supplier price changes, labor cost changes, and overhead shifts.

Immediately after major cost changes — If your primary equipment supplier raises prices by 5% or more, update the affected line items right away. Don't wait for the seasonal review.

After adding new services — Every time you add a capability (maybe you start offering mini-split installs or ductless service), add it to the book immediately with proper pricing. Never let a tech quote a new service type ad-hoc.

Common Mistakes to Avoid

Pricing based on competitors instead of your costs. Your competitor might have lower rent, fewer trucks, or be running on thinner margins than you. Price based on your actual costs plus your target margins. If you can't compete at profitable prices, the answer is reducing costs — not reducing prices.

Forgetting to include warranty labor. If you offer a 1-year labor warranty on repairs, some of those jobs will come back. Factor your callback rate into the price. If 5% of your capacitor replacements result in a warranty return, your average cost per job is actually 5% higher than the single-job calculation.

Using "round number" pricing. $475 is more credible than $500. When customers see a round number, they assume you're estimating. When they see a specific number, they believe it was calculated — because it was.

Building one version for everyone. You need at least two versions of your price book: a field version (service description + customer price only) and a management version (full cost breakdown, margins, notes). Techs should never see your cost breakdowns or margin percentages.

Making It Work With Your Software

A price book in a spreadsheet works when you have two techs. At five techs, it starts breaking down. At ten, it's a mess. You need software that can store your price book, push it to your techs' devices, and update it company-wide when you change a price.

PropertyHQ's HVAC module includes built-in estimating and price book functionality. Your techs pull up the price book on their phone, select the services, and the quote is generated on the spot — with your exact margins baked in. When you update a price in the system, every tech sees the new number on their next job.

The goal is to get pricing decisions out of the field and into a system you control. That's how you protect your margins on every single call.

Start Building Today

You don't need to price every service you offer on day one. Start with your top 20 most common repairs and your standard maintenance pricing. That covers 80% of your calls. Add installation pricing next, then expand from there as you refine your cost data.

The contractors who build and maintain a flat rate pricing book consistently run 10-15% higher margins than those who quote ad-hoc. Over a year, on a business doing $1M in revenue, that's $100K-$150K in additional gross profit. It's worth the upfront effort.
