Based on the SearchLight HVAC & Plumbing Advertising Benchmark, tracking $14.9M in Google Ads spend across 816 contractors and 8,077 campaigns in January 2026, the average cost per lead (CPL) for HVAC and plumbing Google Ads is $104.
That number is misleading on its own. The average cost per lead for branded search campaigns is $34. The average cost per lead for non-branded search campaigns is $149. The average cost per lead for Performance Max campaigns is $72. These three campaign types produce leads at very different costs, with very different conversion rates, and the blended average obscures all of that.
This page breaks down cost per lead by campaign type, by service category, and, critically, connects CPL to the metrics that actually determine whether a lead was worth the money: book rate, cost per paying customer, match rate, and average ticket value.

Google Ads Cost Per Lead by Campaign Type (January 2026)
Google Ads cost per lead varies dramatically depending on whether the campaign targets branded searches, non-branded searches, or runs through Performance Max.
| Campaign Type | CPL | Book Rate | Match Rate | Cost/Customer | Avg Ticket | % of Spend |
| Branded Search | $34 | 55.3% | 68.4% | $104 | $2,398 | 9.1% |
| Non-Branded Search | $149 | 37.6% | 42.1% | $804 | $2,516 | 79.7% |
| Performance Max | $72 | 32.2% | 35.8% | $447 | $2,521 | 11.2% |
| Blended Average | $104 | 41.7% | 48.4% | $472 | $2,465 | 100% |
Branded Search Campaigns: $34 per lead. Branded campaigns target people searching for your company by name. These leads are the cheapest to acquire because the searcher already knows your business. The book rate on branded leads is 55.3%, the match rate is 68.4%, and the cost per paying customer is $104. Branded campaigns accounted for 9.1% of total Google Ads spend across the sample.
Non-Branded Search Campaigns: $149 per lead. Non-branded campaigns target service-intent keywords like “hvac repair near me” or “plumber near me.” These are true customer acquisition campaigns. The book rate on non-branded leads is 37.6%, the match rate is 42.1%, and the cost per paying customer is $804. Non-branded campaigns accounted for 79.7% of total Google Ads spend.
Performance Max Campaigns: $72 per lead. PMax campaigns use Google’s AI to serve ads across Search, Display, YouTube, Gmail, and Maps simultaneously. At $72 per lead, PMax is 52% cheaper than non-branded search. The book rate on PMax leads is 32.2%, the match rate is 35.8%, and the cost per paying customer is $447. PMax campaigns accounted for 11.2% of total Google Ads spend.
The key comparison: non-branded search generates a lead for $149 with a 37.6% book rate. PMax generates a lead for $72 with a 32.2% book rate. PMax leads are less expensive, but convert to booked appointments at a lower rate. The net economics favor PMax because paying $72 for a lead that books 32% of the time costs less per booked appointment than paying $149 for a lead that books 38% of the time.
Why Cost Per Lead Alone Is the Wrong Metric
Most industry benchmarks stop at cost per lead (CPL). That is a mistake. CPL tells you what you paid to make the phone ring. It tells you nothing about what happened after the phone rang.
Two contractors can both have a $150 cost per lead and be in completely different positions:
Contractor A pays $150 per lead with a 45% book rate, a $3,200 average ticket, and a 48% match rate. Their cost per paying customer is $625, and their ROAS is 5.1x.
Contractor B pays $150 per lead with a 28% book rate, a $1,800 average ticket, and a 30% match rate. Their cost per paying customer is $1,071, and their ROAS is 1.7x.
Same CPL. Completely different economics. The metrics that bridge the gap between CPL and profitability are book rate (the percentage of leads that result in a booked appointment), match rate (the percentage of leads attributed to a paying customer in the CRM), cost per paying customer (total spend divided by paying customers), and average ticket (revenue per paying customer).
Cost Per Lead by Service Category (January 2026)
This is the data most contractors actually want: what does a lead cost for my specific trade? The following benchmarks cover non-branded campaigns only, broken out by the service line each campaign targets.
| Service Category | CPL | Accounts | Spend | Book Rate | Avg Ticket | ROAS |
| AC Maintenance | $86 | 17 | $6K | 29.3% | $3,692 | 9.81x |
| Heating Repair | $144 | 137 | $1.37M | 38.2% | $3,225 | 3.69x |
| AC Install | $157 | 87 | $118K | 24.2% | $3,594 | 2.58x |
| Electrical | $163 | 173 | $864K | 41.2% | $2,491 | 2.92x |
| Plumbing | $167 | 404 | $3.61M | 41.5% | $2,208 | 2.72x |
| HVAC General | $198 | 432 | $2.74M | 36.0% | $3,102 | 2.76x |
| Drain / Sewer | $206 | 157 | $985K | 43.3% | $2,188 | 2.15x |
| AC Repair | $231 | 101 | $345K | 37.0% | $3,174 | 2.94x |
| Indoor Air Quality | $274 | 23 | $80K | 39.3% | $3,163 | 1.59x |
| Water Heater | $343 | 83 | $220K | 43.0% | $3,725 | 2.12x |
| Heating Install | $354 | 25 | $49K | 42.8% | $3,269 | 2.22x |
Heating Repair leads January performance. With $1.37M in spend across 137 accounts, heating repair campaigns generated a 3.69x closed ROAS and a $3,225 average ticket, this was the strongest major-volume category. This is seasonally expected for January.
Plumbing is the volume leader. Plumbing commands the most spend ($3.61M) and the most accounts (404). The 2.72x ROAS is moderate, but the 41.5% book rate and $9.8M in closed revenue make it the backbone of many agencies’ Google Ads programs.
Water Heater: highest ticket, highest CPL. Water heater campaigns have the highest average ticket at $3,725, but also the highest cost per lead at $343. The 43% book rate is strong.
AC Install has the lowest book rate. At 24.2%, AC install campaigns convert at the lowest rate in the sample. To see AC install spending money in January is concerning, as this is either an oversight, or the campaign is not properly named because it is truly catching Furnace installs. The low book rate might suggest issues with campaign set up and ensuing lead quality.
HVAC General vs. segmented campaigns. General HVAC campaigns average $198 per lead compared to $144 for heating repair. Service-line segmentation typically reduces CPL by 15-25%.
What a Good Cost Per Lead Actually Looks Like
A “good” cost per lead depends entirely on what happens after the lead arrives. The question is not “is my CPL low?”, it is “does my CPL produce profitable customers at a cost my business can sustain?”
For most HVAC and plumbing businesses operating at roughly 25% EBITDA margins, the math works like this: if your average ticket is $2,500 and your margin is 25%, each job generates $625 in profit. Your cost per paying customer needs to be below $625 to be profitable on a first-job basis.
If your book rate is 38% and your match rate is 42%, roughly 16% of your leads become paying customers. That means you can afford a CPL of up to about $100 before first-job acquisition becomes unprofitable.
The January 2026 data shows the average non-branded CPL at $149, above that $100 threshold. This is why ROAS and cost per paying customer matter more than CPL.
How to Lower Your Cost Per Lead
The contractors in our dataset with the lowest CPLs share several characteristics.
Service-line segmentation. Running separate campaigns for “heating repair,” “plumbing,” and “AC install” instead of a single “HVAC” campaign allows Google to match searcher intent more precisely and typically reduces CPL by 15-25% compared to broad campaigns.
Branded campaign coverage. Many contractors do not run branded campaigns because they assume they will get those clicks organically. Branded campaigns cost $34 per lead and defend your brand name from competitors bidding on it. Allocating even 5-10% of budget to branded search brings down blended CPL significantly.
Performance Max adoption. PMax delivers leads at $72 compared to $149 for non-branded search. The book rate is lower, but the net cost per booked appointment is still favorable. In January 2026, 370 HVAC accounts were running PMax, that number doubled from December 2025.
Landing page relevance. Sending a “heating repair” click to a generic HVAC homepage instead of a dedicated heating repair page increases bounce rate and decreases conversion rate, which directly increases CPL.
Call handling and speed-to-answer. A lead that goes to voicemail is a lead you paid for and lost. CSR responsiveness does not affect CPL directly, but it affects book rate, which determines whether the CPL was worth paying.
RevSync: Offline conversion feedback. Sending revenue and booking data back to Google through tools like RevSync allows Google’s bidding algorithms to optimize toward leads that convert to paying customers, not just leads that click. Contractors using offline conversion feedback typically see CPL decrease and lead quality increase over time as Google’s algorithm learns which audiences produce revenue. Learn more here.

Is Performance Max cheaper than regular Google Ads for HVAC?
Yes. Performance Max campaigns generated leads at $72 per lead in January 2026, compared to $149 for non-branded search. PMax is 52% cheaper on a per-lead basis. The trade-off is a lower book rate (32.2% for PMax vs. 37.6% for non-branded search), but the net cost per booked appointment still favors PMax.
What is the cost per lead for water heater campaigns on Google Ads?
Water heater campaigns have the highest cost per lead in the dataset at $343 per lead, but also the highest average ticket at $3,725. The 43.0% book rate is among the strongest. Reducing CPL on these high-ticket campaigns represents significant upside.
How does cost per lead compare to cost per customer for HVAC?
Cost per lead measures what you paid to generate a phone call or form submission. Cost per paying customer measures what you paid to acquire a customer who actually paid for a service. In January 2026, the average non-branded cost per lead was $149 and the average non-branded cost per paying customer was $804, meaning it takes roughly $804 in non-branded Google Ads spend to acquire one paying customer.
What is book rate and why does it matter for evaluating CPL?
Book rate is the percentage of leads that result in a booked appointment. It is the most important metric for determining whether a cost per lead is acceptable. A $200 CPL with a 50% book rate costs $400 per booked appointment. A $100 CPL with a 25% book rate also costs $400 per booked appointment. Same cost per booked appointment, very different CPLs. In January 2026, branded campaigns had a 55.3% book rate, non-branded had 37.6%, and PMax had 32.2%.
Should I focus on lowering CPL or improving book rate?
Both matter, but improving book rate typically has a larger impact on profitability than reducing CPL. If your CPL is $150 and your book rate is 30%, your cost per booked appointment is $500. Improving book rate to 40% drops that to $375, a 25% reduction, without changing your ad spend or CPL at all. Book rate improvements come from faster speed-to-answer, better CSR training, after-hours coverage, and call handling processes.
