CAC Benchmark for Home Services Businesses in 2026

For home services businesses (HVAC, plumbing, roofing, landscaping, and cleaning), customer acquisition cost is the number that determines whether ad spend is actually profitable. The 2026 data shows a wide gap between channels and trades, and getting the mix wrong is an expensive mistake.

Local Services Ads: The Cost-Efficiency Leader

Google's Local Services Ads (LSA) — the "Google Guaranteed" listings with the green checkmark — remain the cheapest lead source for most home service trades in 2026.

The average cost per lead across home services LSA is $53, based on a large sample of observed ad spend. By trade:

• Electrical: $39 per lead
• HVAC: $51 per lead
• Plumbing: $57 per lead
• Drain and sewer: $59 per lead
• Roofing: $71 to $162 per lead, the widest range of any trade

The average book rate across LSA leads sits at 43.9%, meaning fewer than half of leads convert into a booked job — a number worth factoring in before comparing raw cost-per-lead across channels.

Google Search Ads: Higher Cost, Higher Intent Ceiling

Standard Google Search campaigns cost considerably more per lead than LSA.

• Blended average cost per lead for HVAC and plumbing: $104
• Branded search terms: around $34 per lead
• Non-branded search terms: around $149 per lead
• Performance Max campaigns: around $72 per lead
• Roofing non-branded search: averaging $124 per lead

Local Services Ads cost 40-50% less than standard Search for the same trades, which is why most home services accounts now treat LSA as the primary channel and Search as a supplement for keywords LSA doesn't cover well.

Cost Per Paying Customer by Trade

Cost per lead only tells part of the story — the number that actually matters is cost per paying customer, since not every lead books a job.

• HVAC: $288.29 cost per paying customer, against an average ticket of $2,433.87
• Plumbing: $263.03 cost per paying customer, against an average ticket of $1,707.96

Both trades show a healthy ratio of ticket value to acquisition cost — HVAC customers are worth roughly 8.4x what they cost to acquire, and plumbing customers roughly 6.5x. That ratio is the number to track quarter over quarter, not cost per lead in isolation.

Building a Home Services Acquisition Budget

Start With Local Services Ads

• Step 1: Get Google Guaranteed verified, since unverified businesses can't run LSA at all
• Step 2: Set a weekly lead budget by trade, using the benchmarks above as a starting ceiling
• Step 3: Track book rate weekly — a book rate well below 40% usually points to slow response time, not bad leads

Layer Search for Coverage Gaps

Non-branded Search costs roughly 3x more per lead than LSA for the same trade, so it should be reserved for services or geographies where LSA volume is too thin to hit booking targets on its own.

Track Cost Per Paying Customer, Not Just Cost Per Lead

A trade with a cheap cost per lead but a low book rate can end up more expensive per actual customer than a trade with a higher cost per lead and a strong close rate. Calculate both numbers monthly by trade.

Conclusion

Home services businesses should default to Local Services Ads as the primary acquisition channel given the 40-50% cost advantage over standard Search, use non-branded Search only to fill volume gaps, and track cost per paying customer — not just cost per lead — against average ticket value to know which trades are actually profitable to scale.
