Paste this into your site's HTML wherever you'd like the calculator to appear. It's free to use, keeps a small "Powered by KeepCoolExpert" credit, and you can regenerate a new snippet here any time your details change.

What your visitors get

The same real sizing logic as our own room-size calculator — room dimensions, insulation, sun exposure, and occupancy factored in, a BTU range rather than a single false-precise number, and a running-cost estimate. Visitors can switch between UK, Ireland, Australia and New Zealand — currency, units and typical electricity rates all adjust automatically — so one embed genuinely works regardless of where your customers are.

What you control

Set your own call to action — a quote form, a contact page, or your own product range — instead of ours, plus your accent colour and logo so it sits naturally on your own site. It's free, carries a small credit back to KeepCoolExpert, and needs no account or sign-up — just paste the code.
