What is HVAC flat rate pricing?

Flat rate pricing means quoting a single fixed price for a repair or service instead of billing by the hour. The customer knows the exact cost before work begins, and the shop is incentivized to work efficiently. If the job takes less time than estimated, the shop keeps the difference. If it takes longer, the shop absorbs it — which is why accurate estimating matters.

How do you calculate a flat rate HVAC price?

Start with your true labor cost (hourly rate x estimated hours). Add overhead (typically 25–45% of labor). Add parts and materials at your wholesale cost. Sum these to get your total job cost. Then apply your desired profit margin (typically 35–50%) to arrive at the flat-rate price you quote the customer.

What is a typical HVAC hourly labor rate?

In the US, residential HVAC technician wages range from $25–$45 per hour depending on experience and market. But the labor rate you use for pricing should include the fully loaded cost: wages, payroll taxes, benefits, training, and uniforms. Most shops use $50–$85 per hour as their loaded labor rate for pricing calculations.

What overhead percentage should I use?

Most small HVAC shops run 25–35% overhead as a percentage of labor costs. This covers insurance, vehicle expenses, tools, office/admin, marketing, and any non-billable time. Shops with heavy marketing spend, newer trucks, or higher rent may run closer to 40–45%.

What profit margin should an HVAC repair target?

Residential HVAC repairs and service calls typically target a 35–50% gross profit margin on the total job cost (labor + overhead + parts). Lower-margin work (tune-ups, maintenance agreements) might run 25–35%, while high-skill repairs (compressor replacements, refrigerant leaks) can support 45–55%.

Is this calculator free?

Yes. The Ratchly HVAC flat rate pricing calculator is 100% free, runs in your browser, requires no signup, and has no usage limits.

Should I show the customer the breakdown or just the total?

Most successful flat-rate shops quote one number: the total flat-rate price. Showing the breakdown invites customers to negotiate individual line items (especially labor hours). The flat-rate model works because it shifts the conversation from 'how long will this take?' to 'this is the price to fix it.'
