| Work item | Unit | Material | Labor | What to charge |
|---|---|---|---|---|
3 ton system changeout, 14-16 SEER2 Assumes reusable ductwork and existing electrical. | system | $4,200 | $3,100 | $6,772 to $12,038 |
Gas furnace replacement Venting changes on high-efficiency units add cost. | unit | $1,850 | $1,450 | $3,063 to $5,445 |
Ductless mini split, single head Line set length and electrical run drive the variance. | system | $1,750 | $1,350 | $2,797 to $5,194 |
Flexible duct run, new Attic access and run length are the real cost. | run | $85.00 | $190 | $251 to $466 |
Diagnostic service call Often credited toward the repair if the customer proceeds. | call | $0.00 | $145 | $134 to $249 |
Seasonal maintenance visit Usually sold as a plan rather than a one-off. | visit | $12.00 | $135 | $145 to $242 |
Material and labor columns are bare cost per unit before markup. The charge column applies +15% materials, +20% labor, then +10% overhead and profit, and shows a realistic range rather than one false-precision number.
How this number is built
There is no proprietary data feed here and nothing is hidden. Every figure above comes from four visible steps, which is exactly how your own price book should work:
- 1Start from bare material and bare labor cost per unit, at a national baseline.
- 2Multiply both by your local cost factor, from the ZIP table below.
- 3Add markup: 15% on materials, 20% on labor. This covers waste, procurement and supervision.
- 4Add 10% overhead and profit on the marked-up subtotal, then show a range rather than one number.
Regional cost factors
A national average is close to useless on its own. The same hvac job prices very differently across markets. These are the multipliers applied above, against a 1.00 national baseline.

Before you send this number to a client
Worth doing
- Walk the actual site before committing to a fixed price.
- Itemize disposal, permits and prep as their own lines.
- Write down what is excluded, not only what is included.
- Compare these rates against your own last three invoices.
Where bids go wrong
- Using a national average as if it were a local quote.
- Forgetting that overhead is a real cost, not profit.
- Absorbing prep and access problems instead of pricing them.
- Quoting from memory when material prices moved.
Frequently asked questions
How much should I charge for an HVAC system replacement?
A 3 ton residential changeout with no duct modifications typically prices at about $6,800 to $12,000 installed. Duct replacement, electrical upgrades, and high-efficiency venting are what push jobs past that range.
Should HVAC service calls be flat rate?
Flat rate is now the norm for residential service because it removes billing disputes and lets a faster technician earn more rather than less. Keep the diagnostic fee visible and separate, and state clearly whether it is credited toward the repair.
How much should I charge for emergency or after-hours HVAC work?
A 1.5x multiplier on labor for after-hours and 2x for holidays is standard. Publish the multiplier in advance rather than applying it as a surprise on the invoice.
