A heat pump and ventilation firm lives by the seasons. The first cold week brings faults and urgent messages. A hot summer brings requests for heat pumps that can cool the house. Between the peaks, service agreements keep the firm steady.
Dagny writes the replies, renewals and seasonal posts in your voice. You approve them, and Dagny sends them.
When the temperature drops, many heat pumps stop or show an error code. Dagny drafts a reply that asks for the model, the error code and a photo of the display. You see which jobs need a visit and which need a filter clean. Every request reaches you with the details you need.
A service agreement brings a visit each year and steady work. Dagny finds the agreements that end soon in your email and your CRM. It drafts a renewal for each customer. You approve the list, and Dagny sends the renewals.
Ventilation jobs for housing cooperatives and offices go through a board. Before the meeting, Dagny collects the quote, the emails and the open questions into one brief. You walk in with the facts and the history in one place. After the meeting, Dagny drafts a short follow-up to the board chair for you to approve.
Customers ask about noise, the right size for the house and the cost to run it. Give Dagny the data sheets for the models you sell. Dagny drafts answers from those sheets, not from guesses. You approve each answer before the customer sees it.
In September, Dagny drafts Google posts about service before the winter. In June, it drafts posts about heat pumps that cool the house. You approve each post. Your Google profile shows that the firm is active all year.
Dagny counts last week's heat pump enquiries, fault messages and new service agreements. It shows which ventilation quotes still wait for an answer. You choose the follow-ups.
Dagny reads your Google Calendar and lists the heat pump services this week. It drafts a message to each customer with the day and a note to clear space by the indoor unit. You approve the messages.
Send Dagny your notes from a site visit and the model you suggest. Dagny writes the quote text with the unit, the placement and the noise level from the data sheet. You set the price for the heat pump and approve.
Dagny finds the service agreements that end next month in your email and CRM. It drafts a renewal email to each heat pump owner. You approve the renewal list before Dagny sends them.
Send Dagny a photo of the outdoor unit and the house type. Dagny drafts a Google post and a short text about the install. The heat pump post goes live when you approve it.
October
DSA advises owners to measure radon between mid-October and mid-April, for at least two months. Dagny writes an October post about radon measures, such as ventilation of the ground under the house. You approve the radon post before it goes on your Google profile.
February
A radon test must run for at least two months, so DSA says to start it before mid-February. Dagny drafts a reminder to past customers who asked about radon. You choose who gets it.
March
NAAF expected the first alder and hazel pollen around the turn of February and March in 2026, in the south and west. Dagny drafts a post on when to change the filters in a balanced ventilation unit, and an offer to past customers.
April
The radon season ends in mid-April, and owners get their results. DSA lists ventilation of the ground under the house as a common measure. Dagny drafts a reply for owners with high values, and you add your price.
Hi Anne, thank you for the heat pump service at your house on Wednesday. If the unit runs well, a short Google review helps other owners near you find us. Here is the link.
The review: The customer liked the service but said the technician came an hour after the time window.
Thank you for the review, and sorry that our technician came late. The visit before yours took longer than we planned, and we should have sent you a message. Our technicians now send an update when they run late.
Then gets on with it, where you already are.

Tell Dagny once what it may do on its own and what needs your OK. Routine work runs. Anything new waits for you.

Rules Dagny must always follow
Autonomy
New to AI? Start here.
Offer one at every install, and remind the customer before the first service. Dagny drafts the offer email and the renewal reminders. You approve each renewal before Dagny sends it.
Separate pages for each system, a clear service agreement page, your F-gas certificate and photos of real installs. Add a short fault guide for cold days. Dagny makes the pages and keeps them current from your messages.
Dagny drafts the first reply to each message and email, with the questions you need answered. It does not diagnose the unit. You or your technician decide what happens next.
Many buyers compare more than one installer and read reviews about noise and service. Ask for a review after each install, and show finished installs by house type. Dagny drafts the review requests, the replies and the Google posts. You approve each of them before they go out.
The easiest way is to hand the everyday admin to an AI that already knows the business. For HVAC companies, Dagny answers new enquiries, follows up quotes and keeps the website current, in Slack, iMessage, WhatsApp or email. Tell it "We have capacity for filter changes in September." and it comes back with a Google post, an email to the fourteen customers with older units and two drafts to review by Friday.
The work that repeats every week for HVAC companies: replies to enquiries, quote follow-ups, review requests, the Monday numbers, your Google profile and your website. And the prep: ask "Can you prep me for the Hansen site visit tomorrow?" and Dagny writes a brief with what was agreed and what is still open. Anything you ask for twice can be saved as an automation.
HVAC companies start free with $100 in credits and no credit card. Starter is $20 a month and Human in the loop is $750 a month. No contract, cancel any time.
No. Dagny connects to the tools HVAC companies already use, like Gmail, Outlook, Google Calendar, Google Business Profile, Excel and Stripe, and works in the channels you are already in. Nothing to migrate, and you choose what Dagny can see.
No. Dagny drafts, you approve, Dagny sends. Ask "Can you put the new service hours on the site? 7 to 15 from Monday." and Dagny replies "Here is the site with the new hours. Go live with it?" Nothing goes live until you say yes.
