HVAC Lead Generation That Books Quotes Into Your Diary
We run the Meta and Google ads, qualify every enquiry, reply inside 60 seconds and book the site visit in your name. You turn up and quote.
Who We Are
Scale Theory is an HVAC-only lead generation agency run by two brothers out of Surry Hills, Sydney. We work with air conditioning installers who want a diary full of qualified quotes instead of a feast-and-famine phone.
We build and run the whole engine: the ads a homeowner sees, the page they land on, the six questions that sort buyers from tyre-kickers, the reply inside 60 seconds and the booking in your calendar. You stay on the tools. We keep the pipeline moving and show you what every booked quote cost.

How It Works
Four steps, run for you. Tap any step to see what the homeowner, and you, actually see.
What the homeowner sees
An offer built around your business: a free in-home heat-load check, an install-by date, or the NSW discount where eligible. Real photos of your vans and crew. We never advertise single-room splits.
Ducted in before the heat? 6 install slots left in November. Free in-home heat-load check.
Six questions, about 40 seconds
Property type, current system, install or repair, timing, budget and ownership. Renters without approval and small split enquiries are routed out politely, so your installer never drives to them.
The reply that wins the job
An SMS goes out inside a minute, then a call from our AI receptionist and VA. The site visit is booked before the homeowner has filled in anyone else's form.
Your diary, and the Friday report
Each quote lands with the suburb, system and answers attached. Every Friday: enquiries, booked quotes, cost per booked quote and jobs won, split by Meta and Google.
Homeowners don't book the best installer. They book the first one who calls back, sounds like they know what they're doing, and turns up when they said they would. We make sure that's you.

Book a 15-minute auditWhy Installers Pick Scale Theory
We are new, so we will not show you a wall of borrowed logos. Here is what we put in writing instead.
We do one trade. Every ad, page and question is written for ducted and whole-home air conditioning.
When we book ducted quotes for you in the Hills, we book them for nobody else in the Hills.
Ads run in your Meta and Google accounts. Leads sit in a CRM you log into. It all stays if you leave.
Meta reaches homeowners before they search. Google catches them when they do. One pipeline behind both.
We never advertise single-room splits. Your installer spends the day on jobs worth quoting.

Every Friday you see enquiries, booked quotes, cost per booked quote and jobs won. No vanity metrics.
If you are not a fit, we say so in the first five minutes of the audit, not after a proposal.
Meta and Google need a learning window. After that, 30 days notice. No 12-month lock-in.

Frequently Asked Questions
What does Scale Theory actually do?
We run Meta and Google ads for air conditioning installers, send every enquiry through a six-question qualifier, reply by text and call inside 60 seconds, and book the in-home quote into your diary. Then we follow up the quote on days 1, 3 and 7 and send a review request after the install.
How is a booked quote different from a lead?
A lead is a name and a number. A booked quote is a qualified homeowner, who owns the property and has answered six questions about their home, system, timing and budget, booked into your diary for an in-home quote at a set time. We report cost per booked quote, not cost per lead.
Do you run Google Ads as well as Facebook?
Yes. Meta (Facebook and Instagram) reaches homeowners thinking about ducted before they search. Google Search catches people searching right now, especially when systems break in a heatwave. Both feed the same qualifier, the same 60-second reply and the same Friday report.
Who owns the ad accounts and the leads?
You do. Ads run in your own Meta Business Manager and Google Ads account, enquiries land in a CRM you have a login to, and the landing pages sit on your domain. If you leave, the ad accounts, the data and the pages stay with you.
Do you do split systems?
We lead with ducted, replacement and whole-home systems. We never advertise single-room splits, and a split enquiry never jumps the queue in the qualifier. The work is built for installers where ducted is a big share of the jobs.
Do you work with only one installer per area?
Yes. We take one HVAC business per service line per area. If we book ducted quotes for you in the Hills, we do not book them for anyone else in the Hills. On the audit call we check whether your area is still open.
What happens on the 15-minute audit?
Before the call we pull your current Meta and Google activity and every installer advertising in your area. On the call we show you what we found and how the system would book quotes for you. If it is not a fit, we tell you in the first five minutes.
