Quick Answer
What markup should HVAC companies use?
Typical HVAC markup on parts and equipment, the difference between markup and margin, and how to check your multiplier against the margin you actually need.
The short answer
- Markup and margin are not the same number; a 50 percent markup is only a 33 percent margin.
- Common HVAC parts markup runs 2x to 3x cost; equipment usually runs 1.4x to 1.8x.
- Set the multiplier from the margin you need, not from what a supplier rep suggests.
- Low-cost parts carry the highest multiplier because handling cost is the same regardless of price.
Markup versus margin
Markup is measured against your cost. Margin is measured against the price. A $100 part sold at $150 is a 50 percent markup and a 33 percent margin. Every pricing mistake we find starts with those two words being used interchangeably.
- Margin 30% = 1.43x cost
- Margin 40% = 1.67x cost
- Margin 50% = 2.00x cost
- Margin 60% = 2.50x cost
- Margin 66% = 3.00x cost
Why cheap parts get the biggest multiplier
Sourcing, stocking and carrying a $6 capacitor costs about the same as a $600 board. A flat percentage on both underprices the small parts, which is why sliding scales are standard: small parts at 3x or more, mid-range at 2x, large equipment closer to 1.5x.
Sanity-check your multiplier against the books
Pull last month's gross margin by revenue line. If service margin is under 45 percent while your parts multiplier looks healthy, the leak is unbilled labor hours rather than markup.
Illustration: a sliding parts matrix
- Cost under $25
- 3.5x
- $25 – $100
- 2.8x
- $100 – $500
- 2.0x
- $500 – $2,000
- 1.7x
- Over $2,000 (equipment)
- 1.4x – 1.5x
What this tells you: Example matrix. The point is the slope: handling cost is flat, so cheaper parts must carry more.

In one sentence
Most HVAC companies mark parts up 2x to 3x cost and equipment 1.4x to 1.8x, which lands them at 30 to 55 percent gross margin depending on the work.

Both sliders are at zero, so this matches your numbers above.
Your 12% profit target
You are already there. These numbers keep 15.0% after everything.
What this means
Close, but thin. A few points of price or less overhead makes a big difference.
At this margin you need about $66,000 in sales just to break even.
Numbers to watch every month
- • Gross margin per job type — service work should beat installs.
- • Contribution margin — what is left after every cost that moves with the work.
- • Sales and gross profit per tech hour — the fastest read on productivity.
- • Labor cost as a share of sales, including payroll taxes and benefits.
- • Overhead share of sales — it should shrink as you grow.
- • Unpaid customer invoices over 30 days old.
- • Cash in the bank compared with one month of costs.

Questions people ask
Is 3x markup on a small part unfair to the customer?
The customer is buying a stocked part installed today by a trained tech, not the part alone. What matters is that the total price is clear before work starts.
Should equipment carry the same markup as parts?
No. Equipment moves large dollars with little added handling, so it carries a lower multiplier and a lower margin percentage while still producing more gross profit dollars.
