We nearly quadrupled their ad spend.
Cost per lead fell about 70%.
Renviro Power installs Emerald heat pumps and reverse-cycle air conditioning across Melbourne. They came to us on 6 to 10 leads a week. The 61-day window measured below produced 1,041.
61 days, measured.
1 May to 30 June. Straight out of Ads Manager, with no rounding in our favour.
The part that shouldn't happen.
Push more money into a Meta account and cost per lead usually climbs. You exhaust the cheap audience and start paying for the expensive one. That is the normal tax on scaling. This account went the other way, and both numbers moved at once, in opposite directions.
Daily budget and cost per lead are different units, so both are indexed to 100 at the starting point. That puts them on one honest scale; a second y-axis would let the two lines be slid against each other to say anything.

| Measure | Before | After | Indexed |
|---|---|---|---|
| Daily ad spend | $75.00 | $274.00 | 100 → 365 |
| Cost per lead | $52.50 | $16.06 | 100 → 31 |
Both moved at once, in opposite directions. That is the whole case study.
Lower is better. Bars show the published range where the source gives one; the solid section is the bottom of that range.

Benchmark ranges are published 2026 figures for home-service Meta lead generation. Our number is one account over 61 days, not a promise about yours. Costs move with your trade, market and offer. All figures in AUD.
One account, one 61-day window, one trade, one city. It is not a forecast for your business. A lead costs what your trade, your market and your offer say it costs. It does show what the ceiling looks like when the offer and the follow-up are right.
How these are worked out. All figures in Australian dollars. Before Converxio, Renviro Power ran $75 a day and saw 6 to 10 leads a week, putting their cost per lead between $52.50 and $87.50. Every comparison on this page uses $52.50, the figure most flattering to the previous agency, so the improvement shown is the smallest one their own numbers support. Current figures are total spend of $16,716 across 1 May to 30 June 2026 producing 1,041 leads, giving $16.06 per lead. A lead here means a completed enquiry form, not a click or a message.
In their words.
Hear it from the owner.
Fifteen seconds, unscripted, filmed on his phone.
“Hi, this is Yusuf from Renviro Power. Just a special thanks to John for all his services with generating our leads. Just this week, we got 110 leads. This is what we can achieve with John. Thank you very much.”
That 110 in a single week lines up with the campaign average over the two months measured above, roughly 120 leads a week, against the 6 to 10 they were seeing before.
Where they started: an agency that had stopped paying attention
Renviro Power came to us in February 2025 already running Meta ads through another agency. The account was technically live. It just wasn't going anywhere. Six to ten leads a week, at a cost per lead that made every install a fight to justify, and no real sense that anyone was watching the account day to day.
We wanted something more consistent, higher quality, and scalable in terms of results.
That word, scalable, is the one that mattered. They didn't want a better week. They wanted to be able to put more money in and get more work out, reliably, without the economics falling apart.
What we ran: price, rebates, and a reason to move now
Heat pumps in Victoria are a rebate market. Between VEU, Solar Victoria, STCs and VEECs, the gap between the sticker price and what a household actually pays is large, and most people have no idea. So we led with exactly that: the real number after rebates, and the fact that rebate programs don't stay open forever.
- The offer did the work. The real price after rebates, and a genuine reason to act now.
- Statics beat video. We tested video and UGC properly. A clean static showing the whole offer won.
- Broad targeting. Meta found the buyers, and past enquirers were excluded so budget only chased new people.
- Follow-up that doesn't sleep. Leads land in a CRM, with SMS on a 2, 3 and 7 day cadence and email behind it.
What changed: a week in, it was already different
The shift showed up almost immediately. Within the first week of February 2025 the account looked like a different business. It hasn't been a straight line since; a Meta algorithm change knocked things around for a stretch and we had to rebuild our way out of it. That got fixed, and the account is still running today, more than a year after we started.
Which is worth being straight about: the 61 days measured on this page are from May and June 2026, not from our first two months. We've picked a recent window rather than the opening sprint, because a number from a mature, still-running account is a fairer thing to judge us on than a honeymoon month.
The useful measure isn't in the ad account anyway. Renviro Power's bottleneck stopped being lead flow and became install capacity. The constraint moved from finding the work to getting it all done. That's the point at which advertising has actually done its job.
They've stayed on ever since, which in this business is the only endorsement that really counts.
