Scaling HVAC lead generation in Hawaii from 18 leads a month to 40–60 a week
How an HVAC company in Hawaii scaled Google Local Services Ads, search, Performance Max, and Yelp Ads to 500+ leads in 4.5 months while cutting blended cost per lead from $75 to $27.
The Strategic Challenge
An HVAC company in Hawaii was getting a steady trickle of Local Services Ads leads — about 18 a month — and wanted real volume: residential AC repair, AC installation, and commercial HVAC maintenance contracts, without letting cost per lead explode.
Leads per week, before → after — from the ad accounts.
Key facts
- Client: HVAC company in Hawaii — residential AC repair, AC installation, commercial HVAC repair and maintenance
- Channels: Google Local Services Ads, Google Ads search (residential + commercial), Performance Max, Yelp Ads
- Result: 501 leads on $20,900 in 4.5 months — blended cost per lead trending from $75 down to $27
- Volume: scaled from roughly 18 leads a month to 40–60 leads a week
- Commercial HVAC campaigns produced leads at $12–31 per lead in their best weeks
- Yelp Ads added late as a low-cost contact channel: $2.70–$3.14 per contact
The starting point
At the start the account was small and safe: Google Local Services Ads only, about $865 for the month, 18 leads at $48 each. Fine — but the business wanted growth, and growth means scaling without losing the economics.
What scaling actually looked like
Scaling is where most Google Ads accounts break. In month two, while we pushed budget up, blended CPL briefly spiked above $200 for a week — new campaigns in learning mode, search terms not yet pruned. That week is part of the story: we don’t hide it, we fix it.
The weekly loop — per-channel cost-per-lead review, query pruning, budget reallocation — pulled the account back within two weeks:
| Period | Weekly spend | Leads/week | Blended CPL |
|---|---|---|---|
| Month 1 (baseline) | ~$216 | ~4 | $48 |
| Month 2 (scaling) | $1,320–1,560 | 19–24 | $65–69 |
| Month 3 (peak spend) | $3,240 | 61 | $53 |
| Months 4–5 (optimized) | $900–1,630 | 42–58 | $19–35 |
By month four the account produced 40–60 leads a week at a $19–35 blended CPL — better unit economics than the small “safe” baseline account, at roughly 10× the volume.
The channel mix
- Google Local Services Ads — the workhorse: up to 50 leads a week at $23–45 per lead, with the Google Guaranteed badge doing the trust-building
- Residential search — AC repair and AC installation campaigns, pruned weekly
- Commercial HVAC — repair and maintenance split into separate campaigns with their own budgets, because a restaurant owner and a homeowner search nothing alike; commercial leads hit $12–31 in the best weeks
- Performance Max — incremental fill, down to $12–25 per lead once fed with real conversion data
- Yelp Ads — added in month four as a low-cost contact channel at $2.70–3.14 per contact
Why it matters
Anyone can buy a handful of leads at low volume. The job is keeping the math intact while spend grows 5–10× — and that takes a weekly optimization loop, not a set-and-forget setup. HVAC lead generation in Hawaii is competitive enough that the difference between a managed and an unmanaged account is the difference between $27 and $75 per lead.
