This is what you know as a heat pump installer
Subsidies and high energy prices send a stream of calls your way. You're standing there with an outdoor unit in your hands and can't take them all — and every missed enquiry is a lost installation.
A heat pump system can't be priced over the phone — it takes a site visit and a well-thought-out quote. The AI books the site visit and builds the draft from your notes afterwards.
Every system needs an annual inspection, but it's hard to remember who and when. Service agreements generate the inspection bookings automatically — so you sell service again and again.
Hear what happens when you can’t pick up the phone yourself
You take the calls you can. But when your hands are full, the AI takes over: it answers in Danish, understands what heat pump installers get called about, books the time and sends you a summary. You stay in control — it’s your backup, not your replacement.
- Urgent cases are forwarded to you straight away
- Books directly in your calendar — only in free slots
- You get a summary by SMS, so you always know what was agreed
“We’re considering an air-to-water heat pump — can we get a quote?”
You get it all as a summary — and can always take over yourself.
How Online Erhverv helps heat pump installers
The customer calls, the AI answers in Danish, works out whether it's air-to-water, air-to-air or replacing an oil boiler, and books a site visit directly. Summary by SMS afterwards.
After the site visit the AI drafts the quote from your notes — system type, capacity and hours. You edit and send, the customer signs on their phone.
Set an interval and the system generates the annual inspection bookings automatically and assigns them to an installer. You remember every system — even the ones two years out.
What the day looks like as a heat pump installer — before and after
- Leads pour in during the green wave — and half of them ring in vain
- You head out without a site visit and miss the price by a mile
- The mandatory annual inspections you have to remember to book yourself
- Subsidy and installation papers pile up in a folder in the van
- Quotes and invoices for an installation drag on
- The AI catches every single lead, answers and books the site visit
- The site visit secures an accurate quote — built on your prices
- Service agreements generate the mandatory annual inspection automatically
- Installation and documentation sit collected on the customer's job
- Quotes become invoices that are booked when the job is closed
Not just an AI phone — your whole business in one place
From a sea of heat pump leads to a booked site visit and a mandatory inspection — the installer's green wave under control.
“I lost calls every day, and quotes sat unfinished until late at night. Now the AI answers the phone when I can’t, and the whole business is in one place. I’ve got my evenings back — and customers don’t move on to the next one.”
Frequently asked questions
The questions heat pump installers ask most before getting started. Missing yours? Call or write — you’ll talk to a real person who knows the trade.
Frederik will happily show you what it would look like for your business — free, no sales talk.
Can the AI phone understand heat pump terms like air-to-water, ground source and COP?
Yes. The AI is trained on Danish heating and energy language and can note the system type, home size and current heating, and book a site visit — because a system can rarely be priced without one.
Does the system help with subsidy applications?
We handle customer contact, the site visit, quote, invoice and the documentation on the job — not the subsidy application to the Danish Energy Agency itself. But you have every document and photo collected in one place, so the application is quicker to put together.
What happens to all the calls I can't get to?
When you can't take it yourself — because you're working on a system — the AI takes the call, books a site visit and sends you a summary. You don't lose installations just because demand is high.
Can I sell annual service checks automatically?
Yes. Service agreements generate the recurring inspection bookings automatically and assign them to an installer. It's recurring revenue you don't have to remember manually.
Can you send invoices to Dinero, Billy or e-conomic?
Yes, via a direct API — entries are posted once you approve them. If you use a system without a public API, we send the document by email. We are not an accounting system ourselves.
Do I keep my phone number?
Yes. We set up call forwarding so calls go to the AI when you're on an installation, and straight to you when you're free.
