Common questions
What others asks before signing up?
What size air conditioner do I need for my room?
Room size is the main factor. As a guide, bedrooms (10–20 m²) suit 2.5–3.5 kW, living rooms (20–35 m²) need 3.5–5 kW, and open-plan areas (35–55 m²) typically require 5–7 kW. This calculator uses your room area and type to recommend a capacity — your installer will confirm after assessing insulation, windows and ceiling height.
How much does a split system install cost in Australia?
A standard single-split install ranges from about $1,200 for a 2.5 kW bedroom unit to $4,500+ for a 7 kW premium unit. Multi-split systems serving 2–4 zones can exceed $10,000. Key drivers are unit capacity, brand tier, pipe run length, mounting access and electrical work. Enter your details above for a detailed estimate.
What is the difference between single split and multi-split?
A single split pairs one indoor unit with one outdoor unit — simplest and cheapest per point. A multi-split connects multiple indoor units to one outdoor unit, saving space outside but costing more per zone. Multi-split suits homes needing several rooms cooled with limited outdoor space.
How accurate is this split system cost calculator?
The calculator uses current Australian supply and labour rates to produce an estimate within ±15%. Your air conditioning installer will confirm the final price after a site assessment — ceiling height, insulation quality and cable routing can shift the cost.
Can I add this calculator to my WordPress, Webflow or Squarespace site?
Yes. Copy the one-line embed code from your Leadkit dashboard and paste it into any page on WordPress, Webflow, Squarespace, Wix or Shopify. The calculator inherits your brand colours automatically.
What do I get when a homeowner fills out the calculator?
You receive an instant email and dashboard notification with the homeowner's name, contact details, suburb, recommended kW, system preference, estimated value and a lead quality score. A branded PDF estimate is emailed to the homeowner automatically.
What if I don't have a website?
Leadkit generates a hosted calculator page at your own URL — optimised for Google and ready to share on social media, Google Business Profile or via direct link. No website required.
Is Leadkit really free?
Yes. Free lets you add up to 3 calculators to your website and receive 10 leads per month — no credit card. Every lead beyond the cap is still captured and held for you; upgrading to Pro ($29/mo) opens them all retroactively and removes the cap.
Do I need to know how to code?
No. You get an embed code (one line of HTML). Paste it into your website builder — Wix, Squarespace, WordPress, or any custom site. That's it.
How accurate are the price estimates?
You configure the calculator formulas to match your actual pricing. Leadkit provides the framework; you set the numbers. Estimates can be as detailed or as rough as you like.
What happens with lead data?
All lead data is stored securely in your workspace. You own it. We never sell or share your leads with anyone.
Can I use Leadkit as an agency for multiple clients?
Yes — our Agency plan lets you create and manage separate workspaces for each of your clients, all from one dashboard.
What's the difference between the plans?
Free: up to 3 calculators, 10 leads/month (over-cap leads held + locked until upgrade). Pro: unlimited leads, unlimited calculators, white-label, branded email sending, analytics, email templates. Agency: everything in Pro plus multi-workspace management.

How it works
How this split system cost is calculated
This calculator produces an estimate based on current Australian supply and installation rates — not a binding quote. Your installer will confirm the final price after a site visit.
GST handling: All estimates include 10% Australian GST. The GST component is shown separately in the cost breakdown.
1
Room sizing
Your room area in square metres is multiplied by a type-specific cooling factor to recommend a split system capacity in kW. Bedrooms use a lower factor than open-plan areas due to less heat load.
recommended_kw = ceil(room_area x kW_factor x 2) / 2
2
Unit supply costing
The recommended kW is multiplied by a base cost-per-kW rate and a brand-tier multiplier (budget 1.0x, mid-range 1.35x, premium 1.8x) for each indoor unit ordered.
3
Installation labour
A base install fee applies per indoor unit. Multi-split systems add a premium for each unit beyond the first to cover shared outdoor unit wiring, gas charging and commissioning.
4
Extras and access
Additional costs cover extra pipe run beyond the standard 3 m, high-wall or scaffolding access, relocated outdoor units, and electrical work such as a new circuit or switchboard upgrade.
5
GST and total
All line items are summed, a minimum job fee is applied if the total falls below the threshold, then 10% GST is added to produce the final installed price.
