Flat-rate pricing FAQ
How do you calculate a flat-rate price for an HVAC job?
Add your loaded labor cost (billable hours × fully-burdened hourly rate), your overhead for those hours, and your parts cost to get total job cost. Then price from margin: divide total cost by (1 − your target gross margin). For example, $255 of cost at a 65% target margin = $255 ÷ 0.35 = $728.
What is a good gross margin for HVAC repairs?
Most profitable HVAC shops target 55–65% gross margin on repairs and 35–45% on installs. Repairs carry more risk and overhead per dollar, so they justify a higher margin than large installs.
What is a loaded (burdened) labor rate?
Your loaded labor rate is the technician's wage plus payroll taxes, workers' comp, benefits, and paid non-billable time. It's typically 2–3× the base wage. Always price against the loaded rate, never the raw wage.
How often should I update my pricebook?
At least once a year. Parts costs rise 5–10% annually, and a pricebook that lags behind quietly erodes your margin on every job. Review after any major supplier price change too.
