The problem

HVAC and gas jobs have complex equipment and commercial clients who expect formal proposals

Commercial clients need a proper equipment schedule to raise a purchase order. Service contracts need a completely different structure from installation quotes. Refrigerant, commissioning engineers, and subcontract specialists all need to be named costs or they disappear from the margin. CostForge gives you the structure to win commercial work and protect residential margins simultaneously.

Commercial clients require detailed equipment breakdownsF-Gas refrigerant costs missed on air conditioning installsService contract structure different from install quotingSubcontract labour and commissioning engineers not quotedResidential installs underquoted when controls and filtration excluded

Commercial AC installation: indoor and outdoor units, pipework, electrical connection, commissioning and handover

Save the structure once, import it into a new quote, then adjust items, hours and pricing for the job in front of you.

Frequently asked questions

Questions from hvac and gas engineers evaluating quoting software

Can I quote installations and service contracts?: Yes. Create clearly separated installation and ongoing service scopes so one-off equipment and recurring work remain understandable.
Can I save a repeat HVAC installation scope?: Yes. Save common equipment and labour structures as reusable templates, then tailor each quote for capacity, site requirements and commissioning.
Do you have a focused boiler installation workflow?: Yes. The boiler installers page covers replacement quotes involving appliances, flues, controls, filters and commissioning.

The solution

Built for the way HVAC engineers actually price work

Equipment Schedule as Line Items

Boiler, flue kit, magnetic filter, chemical dosing, programmer, and controls — every component on its own costed line. Clients and facilities managers see exactly what equipment they're buying.

Installation vs Service Contract

Quote a boiler installation and an optional annual service contract as separate sections. Keep the structure clean — no conflating one-off costs with recurring commitments.

Commercial System Proposals

Commercial clients need proposals that match their procurement process. Multiple zones, commercial equipment, commissioning phases, and subcontract specialists — all structured clearly.

Labour Costing by Phase

First fix, second fix, commissioning, and gas safe inspection — each as their own labour phase with the correct engineer rate. Time spent is never absorbed into a single price.

Professional PDF Proposals

Commercial FM clients, housing associations, and contractors won't proceed on a phone quote. Export a structured, branded PDF proposal they can pass through their approval process.

Before & after

What changes when HVAC engineers use CostForge

Boiler install quoted as one price — magnetic filter, chemical dosing set, and programmer not included, client disputes the extras

Full equipment schedule: boiler, flue, magnetic filter, dosing, controls, programmer. Every item on its own line with supply and fit cost. No disputes.

Commercial HVAC proposal submitted as a short email — facilities manager asks for a full breakdown before they can raise a purchase order

Structured PDF proposal: equipment schedule by zone, subcontract engineer, commissioning day, electrical connections. Passes the FM's procurement process first time.

Air conditioning quote doesn't include refrigerant cost — margin absorbed on site when the F-Gas invoice arrives

Refrigerant charge quoted as a named line item with volume and cost. Client sees it upfront; margin protected.
