Extreme Growth · AV & HVAC
From bespoke smart homes to residential air conditioning, we build acquisition systems that turn suitable homeowner interest into qualified appointments and signed contracts.
You already know how to deliver the installation. Your engineers know the equipment. Your designers understand the specification. But getting the right homeowner to recognise that difference before asking for a quotation is another matter.

Audio-Visual & Smart Home
You've probably seen what happens when somebody tries to market a premium smart-home business like an ordinary consumer electronics retailer. The advertisement talks about gadgets. The enquiry asks for a price. The prospect wants a television mounted or a few speakers installed.
Meanwhile, the projects you actually want involve whole-home integration, lighting design, distributed audio, networking, cinema rooms and systems designed around the property.
Those buyers are making a very different decision. They aren't simply choosing a product. They're deciding who they trust to design and install technology throughout their home. Who will work alongside the architect or interior designer. Who understands the complexity of the project. Who will be responsible when something doesn't work. And who will still be there when the installation needs support.
A generic advertisement cannot carry that entire buying conversation.
The message has to begin with the right project. The right homeowner. The right concerns. And a clear reason your business deserves consideration. That's where The Referral Effect comes in.
The Referral Effect
We call this The Referral Effect. It shapes your advertising, landing pages, qualification journey and follow-up — establishing relevance and trust before the sales conversation begins.
Think about your best smart-home client. Perhaps an architect recommended you. Perhaps an interior designer introduced you. Perhaps the homeowner visited a completed installation.
By the time they spoke to you, they already had a reason to trust your expertise. They understood that you weren't simply supplying equipment. You were responsible for the design, integration and performance of the entire installation.
Now consider somebody discovering your company through advertising. They don't have that introduction. Your message needs to establish the relevance and credibility that a recommendation would otherwise help provide.
We begin by understanding your best projects and the people who commission them. The type of property. The stage of the build or renovation. The decision-makers involved. The concerns that matter to them. And the evidence they need before trusting an installer with a substantial investment.
The objective is to attract homeowners who recognise the value of the installation, rather than simply collecting people asking for a cheap quotation.
Smart Home Installation Client Results
Richard
Smart Home$340,000
project closed
Richard runs an established smart-home installation business with a showroom and professional referral relationships. His business already received opportunities through architects and interior designers. The acquisition system created another route to suitable prospects — and within 90 days, a $340,000 project was closed.
5 additional qualified showroom demonstrations generated each month.
Tomas
Smart Home£75,000
average order value
For Tomas, the economics were straightforward. With an average order value of £75,000, one additional project every six weeks could materially change annual revenue. His acquisition activity has been generating four to six booked conversations, associated with one to two sales.
When each project has substantial value, the quality of opportunities reaching the sales team matters enormously.

Air Conditioning & HVAC
The UK residential air conditioning market is changing. Homeowners are increasingly considering air conditioning for comfort, cooling and year-round heating.
According to Checkatrade, jobs posted for air conditioning installation increased 63% year on year in the third quarter of 2025. MyBuilder reported a 320% year-on-year increase in domestic air conditioning installation requests during summer 2026.
For established HVAC installation businesses, growing interest creates an opportunity. But it also creates a problem. A homeowner looking for a single bedroom unit is not the same prospect as somebody planning a ducted system throughout a large property. A homeowner exploring a finance offer may not be ready for a technical survey. And somebody researching heating and cooling options may still need help understanding the appropriate system.
Your acquisition process needs to establish the difference. Because your surveyors and engineers should be spending their time on suitable projects.

Extreme Growth Research · October 2026
We examined 20 UK air conditioning advertisers and tested 14 landing pages. Here's what we found.
Advertisements carried a Book Now button
The overwhelming majority directed homeowners towards information, quotations or form submissions.
Landing pages scored below 50 on mobile performance
Many of the pages were slow enough to create friction before the homeowner even reached the form.
Median largest-contentful-paint
The median LCP across the landing pages we tested.
Advertisers were running five creatives or fewer
A single message reaching every homeowner, regardless of what they were trying to decide.

Most advertisements directed homeowners towards information, quotations or forms. The appointment still had to be arranged afterwards. And many of the pages were slow enough to create friction before the homeowner even reached the form.
For an established HVAC company with installation capacity, those are areas worth investigating.
See how your enquiry process compares.
The pricing trap
Look at the messages homeowners encounter. Fitted from £1,300. From £24 a month. No deposit. Free quotation. Price in 20 seconds.
These messages can attract interest. But they don't necessarily establish the value of a properly designed installation. For a homeowner considering whole-home climate control, the decision may involve system design, efficiency, noise, equipment positioning, property layout, reliability and long-term support.
A single-room installation and a whole-home system have different buying journeys. According to Selectra's October 2026 published estimates, fitted air conditioning costs can range from approximately £1,500 for a basic single-room installation to £15,000 or more for a ducted whole-home system.
Your acquisition process should reflect the type of work you're trying to win — not treat every homeowner as though they're buying the same installation.

The Extreme Growth Acquisition System
We build the system around your installation business: your service area, your target projects, your survey capacity, your sales process and the type of homeowner you want to attract.
For AV, that may mean whole-home integration, cinema rooms, lighting control or specialist installations. For HVAC, it may mean multi-room cooling, whole-home systems or suitable residential heating and cooling projects. We create and test different messages and creative approaches based on the work you want to win.
Dedicated pages built to move homeowners from interest towards qualification without unnecessary delay — designed for speed, clarity and conversion on the device most of them are using.
For AV, property type, project scope, build stage and the systems being considered. For HVAC, room requirements, property circumstances and the type of installation. The questions reflect the installation.
Suitable homeowners can book the appropriate consultation or survey as part of the qualification process — no separate callback required simply to arrange the next step.
Automated conversations help handle enquiries outside office hours and when your team is unavailable — keeping suitable homeowners engaged and moving towards the appointment.
Enquiries, appointments and signed contracts are connected so acquisition decisions can be informed by actual sales outcomes — not just form fills.
We work with your team on the journey from consultation to quotation and signed contract. Because the way a complex installation is explained can have a significant impact on the buying decision.
One connected acquisition system.
Measured against the cost of winning signed contracts.
Delivery
We begin with your business. The projects you want. The customers who buy them. Your current acquisition activity. Your consultation and survey process. And the installation capacity available.
Then we build the agreed acquisition system — positioning, creative, landing pages, qualification, booking, response and reporting. Our commitment is to build and launch within 30 days of commencement. Then we measure and improve the commercial results.
The Guarantee
We establish your existing cost per contract won using agreed advertising expenditure, acquisition management costs and attributable signed contracts. That becomes the starting baseline.
Our commitment is to bring your cost per contract won below that baseline within 90 days.
If we don't, we continue working without our management fee until we do.
The guarantee is subject to agreed conditions, including accurate reporting, timely enquiry handling and the operational cooperation required to measure performance.
UK Air Conditioning Client Result
In a UK air conditioning installation business, monthly installed revenue increased from £120,000 to £344,000 over a 90-day period. That represents an increase of £224,000 per month, or approximately 187%.
This is a substantial result. However, the advertising spend context and precise reporting dates need to accompany the figures before the case study is used as a verified public testimonial.

Exclusivity
We work with one installation partner per agreed service category and protected area. That means we won't build a competing acquisition system for another business offering the same protected installation service within the agreed territory.
AV and HVAC services are assessed separately where the businesses and service offerings do not directly compete. Territory availability is checked before entering an agreement.
Extreme Growth primarily works with established UK AV, smart-home and HVAC companies already investing in customer acquisition — businesses with meaningful contract values, experienced installation teams, a proven service and the capacity to fulfil more work.
For smaller businesses that want to operate the system themselves, we also provide a guided implementation route with tools, training and support. The Installation Profit Audit helps establish which approach may be suitable.

A homeowner becomes interested. They research their options. They discover your business. They decide whether you're worth contacting. They consider the appointment. They compare the quotation. And eventually they decide who gets the work.
Every stage affects what it costs your business to win that contract. Before spending more money attracting enquiries, find out what happens to the opportunities you already create.

P.S. If you've tried paid advertising for AV and concluded it doesn't work, the question worth investigating is what type of projects the advertising attracted, what the homeowners understood about your business and what happened before the sales conversation.
P.P.S. If you're an HVAC installer receiving more enquiries but still spending too much time chasing callbacks and arranging surveys, the audit will help identify which parts of that process deserve attention first.
