(01) The brief
An HVAC company competing on Google against dozens of technicians. The bet was a page that loads before any competitor and answers every customer question on a single screen.
(02) What it does
- Services with reference prices, coverage by district and warranty.
- A form that builds the WhatsApp message with the chosen service and district.
- Frequently asked questions and contact details visible at all times.
(03) How it was built
- Hand-written HTML with critical CSS inline and the rest deferred: no frameworks, no dependencies.
- Local business, service and FAQ structured data.
- A technical rules document so future edits do not break performance.
(04) Security
- No backend: there is nothing to attack.
- Strict headers on Cloudflare.
(05) Speed and Google
Top score in all four Lighthouse categories, on mobile and desktop, verified at every delivery.
(06) What it deliberately doesn’t do
- No online booking and no payments.
