Flat Rate Pricing
A pricing model where a customer pays one fixed price for a service, regardless of how long the technician takes to complete the job. In HVAC, flat rate pricing replaces time-and-material billing with predetermined prices pulled from a pricebook.
$850 to replace a capacitor and get the system back on. That's a flat rate price — the homeowner agreed to it at the kitchen table before your tech touched a single screw. No surprise invoice, no "well it took longer than expected." That predictability is why close rates on flat rate shops consistently run higher than T&M shops: the customer decides yes or no on a number they can see, not a meter running in the background.
Flat rate pricing only works if the underlying pricebook is built correctly. The price has to cover labor burden (including drive time and truck stock replenishment), material cost, overhead allocation, and your target margin — typically 55–65% gross on service work. Most HVAC operators who struggle with flat rate aren't pricing wrong in theory; they're working off a pricebook that was never fully configured. That's not a math problem, it's a setup problem. The 42% of ServiceTitan shops that never finish pricebook setup (per BBB and Capterra complaint patterns) aren't failing because flat rate is hard — they're failing because the software made the build take 6 hours instead of 60 minutes.
In the field, flat rate pricing changes how your comfort advisors and techs talk at the door. Instead of "I'll need to figure out what it costs," the tech pulls up the pricebook on a tablet and presents Good-Better-Best (GBB) options with prices already attached. That shifts the conversation from cost justification to option selection. Average ticket goes up — not because you're charging more per hour, but because customers choose upgrades when the upgrade price is in front of them.
Flat rate is also your callback defense. When a tech charges T&M, a slow tech costs the customer more — and the customer notices. Flat rate removes that friction entirely. The price is the price whether the job takes 45 minutes or two hours. That consistency protects your reviews, your referrals, and your retention.
Frequently asked
What is the difference between flat rate pricing and time-and-material billing?
Time-and-material (T&M) billing charges the customer for actual hours worked plus parts at cost or markup. Flat rate charges one fixed price set in advance, regardless of job duration. Flat rate protects the customer from slow techs and protects you from the awkward 'why did this take so long?' conversation.
How do HVAC shops build a flat rate pricebook?
Start with your fully loaded labor cost per hour — wage, burden, benefits, truck cost, and overhead allocation. Then set your target gross margin (most residential HVAC shops target 55–65% on service). Multiply the labor time estimate by your loaded rate, add material at marked-up cost, and that's your flat rate price. The build is math, not magic. The blocker is usually the software interface, not the pricing logic — which is why shops on clunky tools like ServiceTitan report a 42% pricebook setup failure rate per complaint data on [Capterra](https://www.capterra.com/p/150053/ServiceTitan/reviews/).
Does flat rate pricing apply to HVAC change-outs and installs, or just service calls?
Both — but the mechanics differ. On service calls, a pricebook handles it: the tech selects the repair, the price populates. On change-outs, most shops quote a flat price that includes equipment, labor, permits, and startup — often built from a quote template rather than the service pricebook. The principle is the same: one number, agreed upfront, before work starts.
