Subfloor Ventilation Quoting

Design a subfloor damp and mould extraction system on the plan, then price it in one step.

• Upload a floor plan and AI detects the rooms and areas
• Place a fan, inlet spigots, subfloor vents and flexible duct where they're needed
• Duct runs are optional — a lone fan or spigot is a valid design
• You choose the fan unit, controller and power supply — pricing comes from your Subfloor Ventilation catalogue
• The result is a priced quote, a PDF, an online customer quote page and a supplier take-off

Subfloor Ventilation Quoting is for subfloor damp and mould extraction systems. Upload a floor plan, place the parts where they belong, then turn the layout into a quote. The floor plan is the design surface — there is no separate form editor to fill in.

This feature runs in the Cooledge Portal (desktop) only.

What You Need

Before you can create a subfloor ventilation quote, make sure you have:

• An active Cooledge subscription (any plan)
• The "Heating & Ventilation" industry enabled — Settings → Company Settings → industries. AC-only businesses won't see the Subfloor Ventilation tile until this is added
• AI credits available — each floor plan scan uses AI credits, the same as ducted floor plans (check your balance under Settings → Billing)
• Your Subfloor Ventilation catalogue set up — Settings → Ventilation Catalogue → Subfloor Ventilation
• A floor plan file — PDF (multi-page supported), PNG, JPEG or WebP. Multi-level plans are supported

Setting Up Your Catalogue

Your quote pricing is driven entirely by the Subfloor Ventilation catalogue, so set it up before your first quote. Go to Settings → Ventilation Catalogue → Subfloor Ventilation. There are two tabs:

• Units — your fans, listed at cost price. The sell price shown on the quote is the cost plus the margin from the Materials tab, so you only maintain one number here as prices change
• Materials — your margin, base install and part pricing. A "Price Calculation Formula" card shows how it's built: Unit Margin + Base Install

Set these up once and every subfloor quote inherits them. If prices ever look wrong, this is the first place to check.

Creating a Quote

1. Start a Subfloor Ventilation Quote

You can start from either place:

• Quotes → New Quote, then pick the Subfloor Ventilation tile from the quote type selector, or
• The Floor Plan page

2. Upload Your Floor Plan

Upload the floor plan — PDF (multi-page), PNG, JPEG or WebP. Multi-level plans are supported. Each scan uses AI credits.

Cooledge analyses the plan and detects the rooms and areas, giving you a canvas to design on.

3. Auto Layout (Minimal)

Subfloor systems are laid out by hand more than exhaust systems, so Auto Layout is deliberately light — it drops a fan at most, and you place the rest. This keeps you in control of where the extraction points and inlets go under the floor.

4. Design the System

The palette gives you:

• Inline fan
• Inlet spigots
• Subfloor vents (four vent types)
• Flexible duct in 100mm, 125mm and 150mm

Place these where they're needed on the plan. Duct runs are optional for subfloor designs — a lone fan or an inlet spigot without duct is a valid layout, so you're not forced to draw runs you don't need.

5. Review in the Builder

The builder step summarises the design and lets you make the pricing choices:

• Part counts appear read-only under "From the floor plan". To change these, go back and edit the plan
• Fan unit — choose from your catalogue
• Controller
• Power supply

Pricing is base install + parts + fan with your margin, all from the Subfloor Ventilation catalogue, and is GST-inclusive.

6. Create the Quote

Create the quote and Cooledge produces the priced quote, a PDF, an online customer quote page and a supplier take-off. Subfloor ventilation quotes produce one option.

The Floor Plans list shows a Type badge on each plan so you can tell your subfloor plans apart at a glance.

Reusing Existing Vents

If the subfloor already has vents you're keeping, tick the Reuse existing option on those vents. A reused vent:

• Is not charged on the quote
• Is left out of the parts list and supplier take-off

This keeps your quote and take-off accurate when you're extending or upgrading an existing subfloor setup.

Changing the Design Later

There is no separate form editor for subfloor ventilation quotes. To change a design after you've created the quote, reopen the floor plan from the Floor Plan list, edit the plan, then create the quote again. It updates the same quote record, keeping its reference and its linked customer.

What Your Customer Sees

Your customer gets a professional quote PDF and an online quote page. Because this is a ventilation system rather than air conditioning, the public quote shows airflow in m³/h rather than heating or cooling kW. The design footer you see while working shows the part counts.

Parts List & Take-off

Every subfloor ventilation quote produces a supplier take-off — a parts list you can turn into a purchase order. Reused vents are excluded automatically, so the take-off only lists what you actually need to order.

Tips & Troubleshooting

• The Subfloor Ventilation tile isn't showing. Add the Heating & Ventilation industry under Settings → Company Settings → industries. AC-only businesses don't see it by default
• Prices look wrong. Check your margin, base install and part pricing on the Materials tab, and confirm your fans are entered at cost on the Units tab (Settings → Ventilation Catalogue → Subfloor Ventilation)
• Do I have to draw duct? No. Duct runs are optional for subfloor designs — a fan or inlet spigot on its own is valid
• Need to change a finished quote. Reopen the floor plan from the Floor Plan list, edit it and create the quote again — it updates the same quote
