HVAC Job Pricing Calculator
Price HVAC service calls, installs, and replacements. Enter labor, parts markup, and overhead to get a defensible T&M quote or verify your flat rate.
How this is calculated
The HVAC cost build-up uses the same engine as Job cost quote with HVAC-specific additions: a per-row parts markup, a trip fee that bypasses markup, and an emergency surcharge applied on top of the engine price.
partsWithMarkup = Σ qty × unitCost × (1 + partsMarkup%)
partsWithFees = partsWithMarkup + tripFee [service only]
materialsCost = partsWithFees × (1 + waste%)
laborCost = Σ hours × loadedRate
overhead = per method (fixed | %labor | %total)
directCost = labor + materials + overhead
totalCost = directCost × (1 + contingency%) [T&M]
enginePrice = totalCost / (1 − margin) [margin mode]
= totalCost × (1 + markup) [markup mode]
recommendedPrice = enginePrice × (1 + emergencySurcharge%) [T&M]
── flat-rate reverse ──
totalCost = directCost [no contingency]
impliedProfit = flatRatePrice − totalCost
impliedMargin = impliedProfit / flatRatePrice
impliedMarkup = impliedProfit / totalCostTax is excluded. Verify local tax, licensing, and permit fees before quoting. Loaded rate = wage + benefits + payroll taxes; regional spread is large — edit the default to your real rate.
Replacement quotes start a step earlier, with how much equipment the house actually needs: the HVAC load and BTU calculator gives the pre-Manual-J ballpark before any of these costs are assembled. How the trade sets a diagnostic and call-out charge in the first place is walked through in HVAC service call pricing, and the trip fee this page passes through is priced properly in the trip charge and service call calculator.
Accepted work is dispatched on the HVAC work order template, and the flat-rate side of the tool is easier to sell from a published sheet like the HVAC service price list template. The same cost build-up in a wet trade is the plumbing job pricing calculator.
