The job at a glance
One build, fully itemized, with crew hours.
| Build | Job cost | Labor | Crew hours | Materials | Illustrative selling price |
|---|---|---|---|---|---|
| A. 50-gallon heat pump swap | $3,101 | $1,140 | 5 to 10 h | $1,901 | $4,031 to $6,201 |
Dump fees and other costs ($60) are the same in every build and included in the job cost. Materials include allowances. Illustrative selling price is the job cost at a 30% to 100% markup; your price depends on your own overhead and profit. Labor hours are a planning range and include setup, daily cleanup and material runs; they are never a charge to the customer. Permit and inspection fees are not included; requirements vary by jurisdiction.
Which price is closer to yours?
- Lean, +30%: A handyman or owner-operator who does the work with a small crew and no office. Usually the lowest quote. The owner handles scheduling, questions and callbacks around the work itself.
- Standard, +50%: A remodeling company with a crew, an office, insurance and someone to answer the phone. Close to the average remodeler's overhead in the National Association of Home Builders cost-of-doing-business survey.
- Full-Service, +100%: A design-build firm with designers, a salesperson and a project manager who runs the job. The extra pays for planning, coordination and one point of contact from design to final inspection.
Higher markup means more business behind the job, not by itself better work, and a lower markup is not by itself a better deal. For contractors: how each markup splits into overhead and profit is in the overhead categories guide.
The build in detail
A. 50-gallon heat pump swap: $3,101
The old electric tank is drained, removed and recycled; the hybrid unit is set in the same spot, strapped, connected, and its condensate is run about six feet to the existing floor drain. Labor is $1,140 of the $3,101 job cost, or 36.8%. It is about 5 to 10 hours of work, including setup, daily cleanup and material runs.
Labor cost by trade
Labor only. Materials, allowances and dump fees are in the line items below. Hours are person-hours at typical production from Clamp’s labor hours catalog, as a range: a planning figure, not a schedule and not a charge to the customer.
| Trade | Hours | Labor cost | Lean×1.30 | Standard×1.50 | Full-Service×2.00 |
|---|---|---|---|---|---|
| Plumbing | 3 to 9 h | $1,020 | $1,326 | $1,530 | $2,040 |
| HVAC | under 1 h | $120 | $156 | $180 | $240 |
| Setup, cleanup and material runs | 1 to 2 h | in the prices | |||
| All labor | 5 to 10 h | $1,140 | $1,482 | $1,710 | $2,280 |
Every line item
Labor $1,140 + materials and allowances $1,901 + dump fees and other $60 = $3,101 direct job cost. Hours are person-hours at typical production, on labor rows only, and the direct-cost row adds about 15% for setup, daily cleanup and material runs; an allowance or material row names the labor line that installs it, and a subcontract row has none, because the sub’s price includes their own time. Some labor quantities include a difficulty factor, so they can exceed the measured area; each row’s derivation is in the downloadable data.

Methodology & reproducibility
One reviewed snapshot for this build. The build is frozen from its own estimate run and priced by the published pricer.
Direct cost equals the sum of each row’s rounded quantity × (labor + material + other). Amounts are shown in whole dollars; every column adds to its total.
Scope selection, prose accuracy, arithmetic and provenance mapping reviewed; not independent market-rate verification.

Questions
Why is the unit most of the cost?
The unit allowance is $3,101 minus roughly a day of licensed plumbing labor. A hybrid heat pump unit costs far more than a standard electric tank; utility rebates, where they exist, come off the selling price, not the job cost.
What can push this job higher?
A closed plumbing system that needs an expansion tank, a room too small for the unit's air volume (a louvered door or duct kit), a panel without capacity, or a long condensate run with a pump. Each is its own line when it is found.
Is the markup on top of this?
Yes. Direct job cost is what the swap costs a contractor to perform. The markup table shows what it sells for at illustrative markups of 30% to 100%.
