Converxio. Case study: Connex Electrical (AC installer, North Brisbane)
Case study · AC

From a failed agency to 1,229 AC leads at $9.80 each.

Connex Electrical's first agency burned through two months without a working campaign. We took over in February 2025 and built a $25/day Meta Ads + GHL system that's now 15 months deep, still active, still compounding.

An AC installer burned by his last agency.

When Darren came to us in February 2025, Connex Electrical had just spent two months with another agency that produced nothing. No working creatives, no leads, no system worth keeping. He'd written the spend off and was sceptical that paid ads would ever work for the business.

That was the starting position. Brisbane and North Brisbane homeowners replacing AC systems is a real market, but the previous account had no offer that landed, no audience setup that filtered out tenants and quote-shoppers, and no follow-up that caught a lead before it went cold.

We didn't take over the old account. We started over with a clean campaign, a sharper offer, and a $25/day budget Darren could actually live with while we proved it out.

Fifteen months later, the campaign is still running on the same daily spend it launched with. The creative refresh discipline is what's compounded. Twenty-seven ads tested across the engagement, with one breakout that pulled most of the volume.

A direct offer with real scarcity, on $25/day.

AC replacement is a comparison-shopping market. The buyer is in-market, the install is a planned purchase, and the ad has about three seconds to look like the right offer. So we leaned into proven direct-response principles and let the creative refresh cadence do the rest.

01 / Acquisition

Direct offer + scarcity stack

Classic direct-response copywriting. Time-limited offer language, area call-out for Brisbane homeowners, and anchor pricing (a strikethrough original price next to the discounted current price) to frame value at a glance.

  • 27 ad creatives tested across 15 months
  • Best performer at $9.36 CPL, 828 leads on $7,754 spend
  • Above average quality ranking from Meta on the active winner
  • Weekly creative refresh on the rest of the stack to fight fatigue
02 / Pipeline

GoHighLevel, end-to-end

Full GHL workspace built in Connex's account. Mapped to Darren's quoting and install flow, with the qualification questions designed to filter out the lead types that wasted his old agency's spend.

  • Pipeline: New enquiry → Qualified → Estimate booked → Quoted → Installed
  • Lead form questions: ownership, postcode, system age, timeline
  • Calendar wired to Darren's tech availability with buffer rules
  • Pixel and Conversions API verified before launch and on every campaign change
03 / Automation

Speed-to-lead, no-show recovery

Two automations doing 90% of the heavy lifting. SMS within 60 seconds of form submit. No-show recovery if a booked estimate gets missed. The rest of the lead handling stays with Darren and his team.

  • Speed-to-lead SMS firing within 60 seconds of submit
  • No-show recovery 5 minutes after a missed estimate
  • Reactivation flow for abandoned forms
  • Weekly auto-report to the owner: leads, CPL, quality ranking

Where Darren started vs where Darren is now.

The "before" column reflects the state at the start of our engagement. The previous agency's campaigns produced nothing usable, so paid acquisition for Connex effectively started from zero in February 2025. Fifteen months later, the picture looks like this.

LEADS · $9.36 CPL · ONE CREATIVE

Of the 27 ads we tested for Connex, one outperformed every other by an order of magnitude. AD 1 AC 3 - NEW pulled 828 leads on $7,754 spend, which is roughly two-thirds of the entire campaign's lifetime volume from a single ad. Above average quality ranking from Meta. Still active, still pulling.

Fifteen months, milestone by milestone.

The first month after the agency rebuild was rough. By month three the angle clicked. From there, the discipline was creative refresh on a fresh stack, with one ad eventually emerging as the lifetime workhorse.
