What's the smartest way to generate HVAC leads in 2026?
The Home & Home Improvement category on Google Ads — the benchmark most relevant to HVAC lead generation — carries a median cost per lead of $90.92 in 2026, according to WordStream's annual benchmarks. ACCA's own survey of 1,000-plus HVAC contractors found a bigger problem than lead cost, though: most companies still put 70-80% of their marketing budget into new-customer acquisition, a channel that returns just $3 to $4 per dollar spent, while marketing to their own past customers returns $8 to $12.
- WordStream's 2026 Google Ads Benchmarks put the Home & Home Improvement category's median cost per lead at $90.92, with an 8.05% conversion rate, based on 13,474 US search campaigns run between April 2025 and March 2026.
- ACCA's Contractor of the Future Study, surveying over 1,000 HVAC and refrigeration contractors, found database marketing to past customers returns $8 to $12 per dollar spent — more than double the $3 to $4 new-customer acquisition typically returns.
- Despite that gap, most contractors still put 70-80% of their marketing budget toward chasing new customers, per the same ACCA research.
- ACCA recommends growth-focused contractors invest 10% of target revenue in marketing, well above the roughly 6% the average contractor spends today.
- 45% of consumers now use an AI tool like ChatGPT or Google's AI Mode to find a local business, up from just 6% a year earlier, according to BrightLocal's 2026 survey — AI is now the third most-used discovery channel, behind only Google and Facebook.
What's a normal cost per lead for HVAC and plumbing companies in 2026?
The Home & Home Improvement category on Google Ads — which groups HVAC, plumbing, roofing and remodeling together — carries a median cost per lead of $90.92 in 2026, according to WordStream's 2026 Google Ads Benchmarks. That's alongside an 8.05% conversion rate, a 6.47% click-through rate and an average cost per click of $8.33. The report analyzed 13,474 US search campaigns run between April 2025 and March 2026 across 23 industries, using median rather than mean figures so a handful of outlier accounts don't skew the number. The full cross-industry table lives in our marketing benchmarks index.
Because Google groups HVAC and plumbing into one benchmarking category, that $90.92 figure is a reasonable anchor for either trade — and it's the same category roofing sits in, covered channel-by-channel in Cost per lead for roofing companies: 2026 benchmarks. Other lead-gen verticals run their own category benchmark entirely — see cost per lead for mortgage lenders: 2026 benchmarks or health insurance lead generation: what works in 2026 for how the Finance & Insurance category compares.
How much should an HVAC or plumbing company budget for marketing?
Not as much as most are spending today. ACCA's Contractor of the Future Study, conducted with Farmington Consulting Group and based on a survey of over 1,000 HVAC and refrigeration contractors, found the average contractor currently allocates just 6% of annual revenue to marketing. For contractors actively trying to grow, ACCA recommends 10% — calculated against the revenue target you're trying to hit, not what you already bring in.
Gartner's 2026 CMO Spend Survey put the cross-industry average at 7.8% of revenue — another sign most operators underfund a channel that reliably returns more than it costs.
Why does most HVAC marketing spend go into the lowest-ROI channel?
Because that's where the visible activity is, even though it's not where the return is. ACCA's research found that most HVAC contractors still put 70% to 80% of their marketing budget toward acquiring new customers — cold search traffic, display ads, direct mail to non-customers — a channel ACCA's own data shows returns $3 to $4 for every dollar spent.
Marketing to a contractor's own database — past customers due for a tune-up, a filter change or a system nearing the end of its life — returns $8 to $12 per dollar spent in the same research, roughly two to three times better. It's a quieter channel with no auction to bid into, which may be exactly why it gets less budget than the noisier one.
Are homeowners really turning to AI before Google to find a contractor?
Increasingly, yes. BrightLocal's 2026 Local Consumer Review Survey found 45% of consumers now use an AI tool — ChatGPT, Google's AI Mode, or similar — to find a local business recommendation, up from just 6% the year before. The survey polled 1,002 US adults in February 2026, with 455 of them reporting AI use for a local recommendation in the past year.
AI is now the third most-used discovery channel for local businesses, behind only Google and Facebook and ahead of Yelp and Tripadvisor. ChatGPT accounts for 31% of that AI usage, Google's AI Mode for 23%. The fundamentals in 5 critical factors to rank your website for AI Search Optimization (AISO) apply directly here: an AI assistant recommending a contractor pulls from the same signals — reviews, an accurate Google Business Profile, clear answers on the site itself.
What's the best HVAC and plumbing lead generation strategy for 2026?
Two changes, mostly. First, shift some of that 70-80% new-customer allocation toward the database a company already has — a scheduled maintenance reminder or a seasonal check-in costs a fraction of a paid search click and converts against ACCA's better return. Second, don't starve new-customer acquisition entirely; it's still where net-new revenue comes from, and WordStream's $90.92 benchmark is a fair number to hold that spend accountable to. Within that new-customer budget, Local Services Ads and Google Search Ads price and perform differently enough that the split between them is worth its own decision, not a default.
Third, treat local visibility signals — Google Business Profile completeness, review volume and rating, clear service-area pages — as infrastructure rather than an afterthought. With 45% of homeowners now routing through an AI assistant before they ever see a search results page, those signals now feed two channels at once. The model in Stop wasting ad spend: the blueprint for a profitable paid media strategy — fund what you can measure, then expand — applies as much to a $2M HVAC shop as to an enterprise account.
How much would a $2M HVAC company generate under this approach?
Here's an illustrative model, not a forecast for any specific company. Say an HVAC company earns $2M in revenue this year and wants to grow to $2.5M next year. Following ACCA's 10%-of-target-revenue guidance puts the marketing budget at $250,000 — about $100,000 more than the roughly $150,000 the average contractor at that revenue would spend under the 6% norm.
Split that $250,000 the way ACCA's return data suggests, rather than the 70-80% new-customer default: $100,000 into database marketing to past customers, and $150,000 into new-customer channels like paid search. At ACCA's $8-to-$12 return, that $100,000 alone could influence $800,000 to $1.2 million in revenue. The $150,000 in new-customer spend, at WordStream's $90.92 median, generates roughly 1,650 leads ($150,000 ÷ $90.92 ≈ 1,650), and at ACCA's $3-to-$4 return contributes another $450,000 to $600,000. Combined, that's $1.25 million to $1.8 million in influenced revenue — well ahead of the $750,000 to $1 million the same $250,000 would return if all of it went to new-customer acquisition alone.
FAQ: HVAC and plumbing lead generation
What is a good cost per lead for an HVAC or plumbing company in 2026?
WordStream's 2026 Google Ads Benchmarks put the median cost per lead at $90.92 for the Home & Home Improvement category, which covers HVAC, plumbing, roofing and remodeling together. That figure comes from 13,474 US search campaigns analyzed between April 2025 and March 2026, using median rather than mean values.
What percentage of revenue should an HVAC company spend on marketing?
ACCA's Contractor of the Future Study found the average contractor spends about 6% of revenue on marketing, but recommends growth-focused contractors invest 10% of their target revenue instead. That guidance comes from a survey of more than 1,000 HVAC and refrigeration contractors conducted with Farmington Consulting Group.
Is marketing to past customers really more profitable than chasing new ones?
Yes, according to ACCA's research. Database marketing to past customers returns $8 to $12 for every dollar spent, compared with $3 to $4 for new-customer acquisition. Despite that gap, most contractors still put 70% to 80% of their marketing budget toward acquiring new customers rather than their existing base.
How many homeowners now use AI to find a local HVAC or plumbing company?
45% of consumers used an AI tool like ChatGPT or Google's AI Mode to find a local business recommendation in 2026, up from just 6% the year before, according to BrightLocal's Local Consumer Review Survey. AI is now the third most-used local discovery channel, behind only Google and Facebook.
Does this data apply to plumbing companies as well as HVAC?
Largely, yes. WordStream and BrightLocal's data cover home services and local business behavior broadly, not just HVAC. ACCA's contractor survey is HVAC-specific, but its core finding — retention marketing outperforms new-customer acquisition — holds for any trade with a repeat-service customer base.
Put this to work.
Pull a report on what share of last year's marketing budget went to past customers versus new-customer acquisition, and compare it to ACCA's $8-to-$12 versus $3-to-$4 return gap. Benchmark your paid search cost per lead against WordStream's $90.92 median before assuming a channel is underperforming. Build a standing database campaign — maintenance reminders, seasonal check-ins, replacement-age outreach — for customers you've already won. Then audit your Google Business Profile and reviews, since that's what an AI assistant cites when a homeowner asks for a recommendation.
