HVAC Plan: Fund the Installation Before Commissioning
Decide how many installations can be delivered and funded before final customer collection.
On this page
An HVAC installation can show a positive margin while requiring substantial cash before commissioning. Plan the equipment order, qualified crew time and customer milestones together; the invoice total alone answers none of those questions.
Define a complete installation
Keep service calls and maintenance obligations on their own calendar. For installations, specify equipment, site work, commissioning and included return work. Do not add installation revenue to a fully booked service roster without removing the hours it consumes.
Eight installations leave $1,400 in this illustration
Original assumptions, $ for one month. Each installation sells for $5,000. Equipment costs $2,500, direct labor $1,000 and consumables $100. A further $100 per job is reserved for callbacks, making total expected job cost $3,700. The separate monthly operating commitment is $9,000 and excludes that direct labor.
Contribution is $1,300 per installation. Eight jobs produce $40,000 revenue, $29,600 expected job cost and $1,400 after the operating commitment. Seven jobs leave $100; six lose $1,200. Assume 160 qualified crew-hours available and 16 hours per job, including the selected return-work allowance. Ten installations is the assumed ceiling, not a demand forecast.
A budget provision is not an immediate cash payment
| Event | Cash movement | Cumulative balance |
|---|---|---|
| 20% customer deposits | 8,000 | 8,000 |
| Equipment, direct labor, supplies and monthly commitment before completion | -37,800 | -29,800 |
| Commissioning balances on day 30 | 32,000 | 2,200 |
| Assumed callback payments on day 45 | -800 | 1,400 |
The selected funding gap is $29,800. The $800 callback budget becomes cash in this illustration only on day 45; placing it in early procurement cash would overstate the early gap. Different actual callback dates or supplier credit change the schedule.
Obtain written equipment terms and customer milestones, then test a commissioning delay without delaying wages by assumption. Check crew competence, hours and existing maintenance duties separately. The selected HVAC financial model is the seller's broader Plumbing and HVAC model; use it for the operating forecast alongside this installation cash schedule.
Scope & limitations
Assumed installation-only month; other service work, tax, financing and capital purchases are excluded. Callback budgets are distinct from dated payments.
