Job costing for HVAC contractors
On an HVAC install, the equipment can be half the cost of the job, and its price can change between the bid and the order. The rest of the margin is in install labor and ductwork. JobMargin tracks both against the job so a price bump or a slow rough-in doesn’t hide until the end.
What HVAC contractors track in JobMargin
- Units and equipment, separately. Big-ticket equipment gets its own category, so a price increase between quote and order is obvious.
- Ductwork and sheet metal. Fabricated or bought, it posts against its own budget.
- Refrigerant, permits, and crane days. The costs that are easy to forget on the bid each have a place to land.
- Bids by the ton or by the piece. Price equipment by tonnage (TON), registers and grilles by each, and duct runs by the linear foot.
Set up for HVAC from the first day
When you pick HVAC as your trade, JobMargin loads these cost categories for budgets, receipts, and job costs. You can rename or add your own at any time.
- Units & Equipment
- Labor
- Ductwork & Sheet Metal
- Materials
- Refrigerant
- Permits
- Tool Rental
- Fuel
- Subcontractor
- Other
Bid line items use the units HVAC actually bid in: tons (TON), each (EA), linear feet (LF), square feet (SF), and lump sum (LS).
Example: what a HVAC job looks like mid-way
Both units are set (one crane day), and duct rough-in is about half done.
| Cost category | Budget | Spent so far |
|---|---|---|
| Units & Equipment | $38,000 | $38,900 |
| Labor | $24,000 | $11,200 |
| Ductwork & Sheet Metal | $12,000 | $8,400 |
| Materials | $4,000 | $2,100 |
| Refrigerant | $1,500 | $0 |
| Permits | $900 | $900 |
| Tool Rental | $1,600 | $1,450 |
| Total | $82,000 | $62,950 |
The units came in $900 over the bid because of a price increase between the quote and the order. That’s worth checking against your supplier quote dates on the next bid. Labor is 47% spent with rough-in about half done, right on plan.
