Creator of this template ai-website.com The story
A contractor that shows its prices
Read the full story
Most websites of air conditioning contractors show an outdoor unit against a blue sky, three brand logos and a contact form. Anyone with a hot loft in July learns neither roughly what a system costs, nor when it is installed, nor what happens in an emergency.
Luvhagen answers exactly that. Every service names prices and duration, the enquiry works out a guide price in three steps, and a drawn diagram explains why one unit can cool and heat. Subsidy calculator, running costs and room configurator answer the questions that otherwise come on the phone.
Behind it stands a whole business: eight services, three sectors, project reports with measured values, guides, a maintenance contract and an emergency service with a map. What is missing are your own photos and prices, and every contractor adds them with their AI.

Scroll through the homepage
The Luvhagen homepage travels as you scroll. Each stop explains why a section is built the way it is.
- 01
The red lead tile
The service grid has exactly one red tile, it fills from the left as it scrolls in. The pattern carries the whole site, as price tile, as promise and as guide price.
- 02
The system diagram
Indoor unit, lines and outdoor unit as a drawing, with a switch between cooling and heating and four stages that highlight each other.
- 03
The installation day
Eight stages from 7:30 to 16:30, a clock with a progress ring shows where the day stands as you scroll.
- 04
The subsidy calculator
Set the system price, tick the bonuses, and your share appears, capped at 70 percent and at the eligible costs.
- 05
The map of the region
A drawn map around Hannover with response times per town, on the phone as a list below.
- 06
The three-step enquiry
Building, project and contact, with every field checked, a guide price alongside and a confirmation that says what happens next.
Not one page. All of them
You are not buying a homepage full of promises, you are buying a complete website. Every subpage is fully designed and written.
1 / 6
The centrepiece
A guide price that works itself out
The enquiry asks for the building, the service and the number of rooms. Next to it a red tile shows a price range straight away, and every change recalculates it.
- A range instead of a question
The most common question before the first call is roughly what it costs. The enquiry answers it before anyone calls, and the site visit starts with a range.
- Commercial works out differently
Homes, commercial or industrial change the factor, single-split or multi-split the range. The note below the price says what it includes.
- Values in one file
Base prices, ranges and factors are rules of thumb in the calculator. Your AI enters your figures, the enquiry stays.

Who Luvhagen is built for
A template gets good by making choices. Luvhagen is tailored to one niche, and honest about where it does not fit.
Built for
- Air conditioning and refrigeration contractors who install and service split and multi-split systems
- Heating, plumbing and ventilation firms with heat pumps, duct cleaning and an emergency service
- Agencies that deliver building services contractors repeatedly and predictably
Not meant for
- Manufacturers and wholesalers who sell units rather than installation and service
- Contractors who do not want to name prices, the template lives on guide prices
- Joinery and timber construction firms, Asbrock in the same category fits them better

Quick answers
As soon as you enter them. Guide price, room configurator, subsidy calculator and running cost calculator work with a few rules of thumb that live in src/scripts/rechner.ts and in the data files. Your AI enters your prices and rates in one pass, and the prices on the service pages follow.
Yes. The eight services are entries in src/data/leistungen.ts. A new entry creates a complete service page with opening, package contents, process, prices and questions, a deleted one disappears from the menu, overview, finder and footer.
Yes. Services, sectors and calculators are data. A heating firm moves heating and heat pumps to the front, a ventilation contractor duct cleaning and indoor air. The page structure stays the same.
They are checked as of September 2026 and marked with that date on the page. Subsidy rates and deadlines change, which is why they live in data files. Before going live, enter the current values, the copywriting skill says what to watch when advertising subsidies and savings.
No. Company, names, prices, projects, key figures and testimonials are invented for this template and marked as examples on the page. There is deliberately no rating score, not in the structured data either. START-HERE.md says what has to be replaced before going live.
As placeholder pages with instructions, not as finished texts. The legal notice lists the mandatory details of a specialist contractor, the privacy page describes what the website does technically. We deliberately do not supply legal texts, because they differ for every business.
No. The font and all images are hosted locally, the maps are original drawings, there are no tracking pixels and no Google Fonts. The consent choice and the maintenance checklist are stored in the browser.
Yes. Every heading, every text and every key figure is there without a script, the calculators show a finished starting state, and the mobile menu opens as a jump link. Filters, calculators and forms need JavaScript, but their content is readable without it.
The English version addresses visitors as you throughout, in a plain and factual tone, including form messages and the consent dialog. Your AI adjusts the tone in one pass if your business speaks differently.
Anywhere that serves static files. Astro builds the site into a folder of finished HTML that runs on any web space, without a database or server script. The contact and enquiry forms check the input and send nothing yet, they need a recipient before going live.
Yes. Pay once, yours forever, for your own projects and client projects. You get the complete source code without a watermark and without a subscription.
The photos come from Pexels and may be used commercially, but they show no real business, no real staff and no real projects. Your own photos belong in the team and project sections. IMAGE-CREDITS.md names the photographer and source of every motif.
No. You tell your AI in the project folder what should change, and it finds the place through CLAUDE.md and the seven skills. If you want to work by hand, all texts are in a few data files under src/data.
