A single markup on every part is the most common pricing mistake in a small HVAC business. Apply it to a capacitor and the part is priced fairly but the margin in dollars is trivial; apply it to a compressor and the price becomes indefensible while the dollar margin is more than the job needs. The parts markup chart solves this by sliding: cheap parts carry a high markup, expensive parts a lower one, so the dollar margin on each part is proportionate to the risk and the handling it carries. This page is for the owner of a US HVAC contracting business asking how the HVAC markup chart works and how to build one from their own figures rather than copying a table.
Why one markup fails at both ends
The markup on a part has to cover ordering it, stocking it, carrying it on the truck, warranting it, and the risk that it is wrong or fails. Those costs do not scale with the part's price: a contactor and a compressor take similar handling. A flat markup therefore under-recovers on cheap parts and over-recovers on expensive ones, and customers notice the second while you fail to notice the first.
The shape of a sliding HVAC markup chart
Bands by cost: the cheapest parts carry the highest multiplier, and each band up carries a lower one, down to a floor multiplier on the most expensive equipment. The exact multipliers are yours to set from your margin target; what matters is the shape, and that the resulting price is defensible when a customer looks up the part online. The bands are usually set so that the dollar margin rises gently as the part cost rises, never falls.
Building yours from the margin target
Decide the gross margin you need on parts overall, from the same overhead and profit arithmetic that sets the labor rate. Then set the bands so that the mix of parts you actually sell produces that margin: high on the many cheap parts, lower on the few expensive ones. Test it against last quarter's parts sales; if the blended margin lands where you need it, the chart is right for your mix.
Where the chart lives
In the price book, applied automatically when a task is priced, and on the technician's phone so the price presented is the price on the invoice. A chart the technician has to apply by hand is a chart applied inconsistently. The labor rate calculator on this site works the labor half of a task price and takes a parts markup as an input, which is a quick way to see how a band changes a real task's price.
Reviewing it
Suppliers reprice more often than markup charts are reviewed. When part costs move, parts migrate between bands and the blended margin drifts. Review the chart against parts sales twice a year and whenever a supplier issues a new price list.
Questions people ask about hvac parts markup chart
What is a typical HVAC parts markup chart?
A sliding scale with several cost bands, highest multiplier on the cheapest parts, lowest on equipment. The multipliers are yours to set from your margin target; copying another shop's chart copies their costs.
Should the markup be shown to the customer?
No. The customer sees a task price with parts and labor together, or options. The chart is an instrument for pricing, not a line on the invoice.
Does the chart apply to equipment on installs?
Installs are priced from cost with a margin applied to the whole job, not with a parts markup. The pricing calculator on this site does that arithmetic.
