How HVAC firms get paid
Mechanical-services contractors earn money two ways. Project and install work — ducted systems, VRF, chillers, mechanical plant — is usually subcontracted on commercial jobs and paid against progress claims, with a meaningful chunk withheld until commissioning and handover. Service work runs on planned-maintenance agreements and reactive call-outs, billed to building owners, facilities managers and strata.
HVAC concentrates working-capital risk because the plant is expensive. A contractor may order condensers, air-handling units and controls — long-lead, high-value equipment — well before the matching progress claim is certified. That outlay sits on the contractor's balance sheet, and a single delayed final payment on a large install can dwarf a small firm's monthly cashflow.
Why payments stall
The signature HVAC dispute is over commissioning. Final payment is often tied to a system performing to specification, so a builder or principal can withhold the last claim by pointing to a balancing issue, a noise complaint or an outstanding commissioning report — sometimes legitimately, sometimes as leverage. Warranty and defect arguments extend the same lever well past handover.
On the install side, the usual construction problems apply: short-paid progress claims, contested variations, and a head contractor passing cashflow pressure down. On service agreements, the friction is slower — a facilities manager or strata committee that simply lets maintenance invoices age in a queue.
Red flags on an HVAC account
Watch for a final claim held against a vague or shifting commissioning objection, retention that is never released after the defects period, and a facilities manager who keeps maintenance invoices perpetually thirty days back. A large install for an under-capitalised developer is a structural risk, because the value tied up in plant and final claims is significant.
On subcontract work the Security of Payment timeframes apply, so a disputed commissioning claim should be reviewed promptly rather than left to drift past the statutory windows.
How Merion recovers it
Merion recovers commercial HVAC debts on a commission-only basis, so a contractor can pursue a withheld final claim without an upfront fee. The review centres on the contract, the progress claims, the commissioning and handover records and the variation trail — because a commissioning dispute turns on documentation. A professional demand separates a genuine performance issue from a principal using commissioning as a stalling tactic.
If an HVAC client has a held-up final payment or aged service invoices, pass it on through refer a debt or request a free debt appraisal.
Key takeaways
- Expensive, long-lead plant is funded before the matching claim is paid.
- Final payment is commonly tied to commissioning sign-off.
- Commissioning and warranty objections are frequently used as leverage.
- Documentation of handover and performance is decisive in these matters.
FAQ
The builder is withholding final payment over a commissioning issue — can we still recover?
Often, yes. A genuine performance defect can be separated from a builder using commissioning as a reason to delay. The contract and commissioning records drive the assessment.
Retention on a completed install was never released — is that recoverable?
Unreleased retention after the defects liability period is a common and recoverable issue. The contract terms and completion records establish entitlement.
Are aged maintenance-contract invoices worth referring?
Yes. Recurring service invoices that keep ageing in a facilities queue can be pursued, and a professional demand often resets a slow-paying agreement. This is general information, not legal advice.
