Every HVAC owner eventually asks the same question, usually in the slow week after the spring rush when the P&L is finally sitting still long enough to read: how much should I actually be spending on marketing? Too little and the phone goes quiet by August. Too much and you’re feeding Google and Meta a number you can’t justify. Most owners either pick a figure out of the air or copy whatever the last vendor told them — and both are how good shops quietly overspend on the wrong channels while under-investing in the ones that book jobs.
Here’s the short answer, up front: most HVAC contractors should budget between 7% and 10% of revenue on marketing in a normal year, and lean toward 10–15% if you’re young, growing aggressively, or fighting for share in a crowded metro. That range is anchored in hard data — company-wide marketing budgets averaged 7.7% of revenue in 2025 according to Gartner’s CMO Spend Survey, while The CMO Survey (Deloitte / Duke) put it at 9.4%, with consumer-facing businesses running higher. HVAC is a local, consumer-facing service — so the higher end of that band is the honest target, not the low end. This guide breaks down the benchmarks, how to set your own number, exactly where the dollars should go by channel, and the metric that matters more than the size of the budget.

The short answer: how much HVAC contractors should spend
Pick your number as a percentage of revenue, not a random monthly figure. A budget of “$3,000 a month” means nothing until you know what it’s a percentage of — that’s a healthy spend for a $500K shop and a rounding error for a $5M one. The percentage-of-revenue frame is how every serious benchmark is reported, and it’s how you keep marketing scaling with the business instead of getting frozen at whatever felt comfortable three years ago.
For a typical residential HVAC shop, the working range is:
- Established, steady-state shop (5+ years, holding share): 6–8% of revenue. You have a customer base, a review moat, and repeat/maintenance-plan revenue doing some of the work for you.
- Growing shop (taking share, adding trucks): 8–12% of revenue. You’re paying to expand the funnel faster than word-of-mouth can.
- New or aggressive shop (under ~3 years, or entering a new market): 10–15%+ of revenue. You’re buying a customer base and a review profile you don’t have yet, and that’s front-loaded.
Those three numbers frame the whole decision: a defensible total budget in the high single digits of revenue, with paid ads taking the largest single slice but nowhere near all of it. Everything below is about turning that frame into a plan for a shop that runs trucks, not a SaaS company.
What the benchmarks actually say
There’s a widely repeated “rule of thumb” that small businesses should spend 7–8% of revenue on marketing, usually attributed to the U.S. Small Business Administration. We’ll be straight with you: that specific SBA figure has no verifiable primary source — it circulates on agency blogs without a real citation. So ignore the folklore and use the numbers that are actually documented.
The most authoritative recurring measurement is Gartner’s annual CMO Spend Survey. In 2025 it found marketing budgets flat at 7.7% of overall company revenue, unchanged from 2024. That survey skews toward large enterprises (most respondents report over $1B in revenue), so treat 7.7% as a floor for a small local service business, not a target.
The CMO Survey, directed by Dr. Christine Moorman and sponsored by Deloitte, Duke’s Fuqua School of Business, and the American Marketing Association, includes far more small and mid-sized firms — and it reported 9.4% of revenue in 2025, up from 7.7% the year prior. More useful for you: it breaks the number down by business type, and consumer-product (B2C) companies came in at 15.5% of revenue. HVAC is a consumer-facing service business — closer in customer behavior to B2C than to a B2B enterprise — which is exactly why the low-single-digit “floor” undersells what a competitive shop needs to spend.
How to set your own HVAC marketing budget
The percentage is a starting point. Here’s how to land on the actual dollar figure for your shop.
1. Start from revenue, and be honest about which revenue. Use trailing-twelve-month revenue, not last month’s or your best month ever. If you did $1.4M last year and you’re an established shop, 8% is ~$112K/year, or about $9,300/month — that’s your all-in marketing number, ads and everything else.
2. Decide whether you’re defending or growing. Defending share (steady revenue, protecting your service area) sits at the low end. Growing (adding a truck, entering a suburb, chasing installs) means spending ahead of the revenue you want — closer to 10–12%.
3. Subtract what’s already committed. Your website, CRM, review tools, and any retainer agencies come out of the same budget. Owners routinely forget these and then “discover” they’re spending more than they thought once software and a marketing coordinator’s time are counted.
4. Set a floor for the slow season, not just the peak. The instinct is to go dark in the shoulder months. Resist it. The homeowner who books a fall furnace tune-up in September is the same one who calls you first for a $9,000 no-heat replacement in January. Cutting spend to zero off-season just means paying full price to re-acquire attention when everyone else is bidding.
5. Reserve 10–15% of the budget to test. One new channel, one new offer, one new landing page per quarter. The shops that plateau are the ones running the exact same two campaigns they ran in 2022.
The budget question is really two questions in a trench coat: how much to spend, and how little of it to waste. Most owners obsess over the first and ignore the second — which is backwards, because waste is the cheaper problem to fix.
Where the money should go: budget allocation by channel
A number is useless without an allocation. Here’s a defensible starting split for a residential HVAC shop spending in the 8–10% range. Adjust to your market, but the shape holds: paid demand capture is the biggest slice, and a meaningful chunk goes to converting and keeping customers — not just buying new ones.
Sample HVAC marketing budget allocation (residential shop)
| Channel / line item | Share of budget | What it buys |
|---|---|---|
| Google Local Services Ads + Google Ads | 30–40% | Bottom-funnel demand — homeowners actively searching 'AC repair near me' right now |
| Local SEO, Google Business Profile & reviews | 15–20% | The free clicks and map-pack rankings that compound over years |
| Website, landing pages & booking system | 10–15% | Where every paid click lands — the difference between a lead and a bounce |
| Meta / Facebook & short-form social | 10–15% | Top-funnel demand gen, tune-up offers, and remarketing to past visitors |
| Retention: email + SMS to your customer list | 10–15% | Maintenance-plan renewals, seasonal reminders, reactivation — the cheapest revenue you have |
| Brand & offline (trucks, yard signs, direct mail) | 5–10% | Local trust and repeat visibility in your service area |
| Testing reserve | 5–10% | New channels and offers each quarter |
Notice what that split refuses to do: pour 100% into Google and hope. Here’s the logic behind the big buckets.
- Paid search and Local Services Ads get the largest slice because they capture homeowners at the exact moment of need — the no-cool call in July, the no-heat call in January. LSA in particular puts you at the top with a “Google Guaranteed” badge and charges per lead, not per click.
- Local SEO and reviews are the compounding asset. Ads stop the day you stop paying; a strong Google Business Profile and a steady drip of fresh reviews keep pulling in free map-pack clicks for years. This is why review generation deserves real budget, not an afterthought — homeowners lean on reviews heavily before they ever call.
- Your website and booking flow are the conversion multiplier. It doesn’t matter how cheap your leads are if they land on a slow page with no obvious way to book. Every dollar here makes every dollar in the ad buckets work harder.
- Retention is the highest-ROI line on the sheet. Selling another tune-up, IAQ add-on, or replacement to an existing customer costs a fraction of acquiring a stranger — and it runs on email and SMS you can automate. Email marketing has famously returned around $36 for every $1 spent in Litmus / DMA benchmarks; for HVAC, that “$1” is a list you already own.
What HVAC leads actually cost in 2026
To size a budget, you need a rough feel for what a lead costs — because “8% of revenue” only works if that money buys enough jobs to grow. Hard, tier-one HVAC cost-per-lead data barely exists (channel-level numbers come from marketing agencies, not government surveys), so treat the figures below as industry-reported ranges, named by source, not gospel.
- Google Local Services Ads: agency SearchLight Digital reports home-services LSA leads averaging around $53 each (HVAC specifically near $51), drawn from millions in tracked spend across hundreds of contractors. LSA also tends to convert leads to customers at a higher rate than traditional PPC, because the intent is high and the badge builds trust.
- Google Search (PPC): WebFX pegs HVAC search-ad cost-per-lead around $104, higher for non-branded terms — you’re bidding against every other shop in town on the same “AC repair” keywords.
- Meta / Facebook: roughly $35–$150 per lead depending on the offer and creative, per WebFX and contractor-marketing datasets — cheaper leads, but colder intent, so they need a real follow-up sequence to convert.
Do the arithmetic in your own numbers. If a booked job is worth an average ticket of, say, $450 on service and far more on install, and it takes two or three leads to book one job, a $53–$104 lead is comfortably profitable — if you actually book it. That “if” is the whole game, and it’s why the budget conversation always circles back to conversion. For a full channel-by-channel breakdown, see our HVAC cost per lead benchmarks for 2026.
Why ad costs are rising — and what to do about it
The reason “just spend more” is bad advice in 2026: the price of attention is climbing, and home services is one of the most expensive verticals there is. LocaliQ’s 2025 search-ad benchmarks put the average Google Ads cost-per-click for Home & Home Improvement at $7.85 — among the highest of any industry — and found CPC rose year-over-year for 75% of home-services business categories. WordStream’s 2025 benchmarks tell the same story: the auction keeps getting more expensive, and Gartner notes that media price inflation means CMOs are getting less for every dollar.
When the price of a click goes up and the click gets you the same lead, the only ways to protect your margin are:
- Convert more of what you already buy. A 10% lift in your booking rate is worth more than a 10% budget increase — and it doesn’t cost you $7.85 a click.
- Own more free demand. Reviews, local SEO, and a strong Google Business Profile lower your blended cost per job by mixing free map-pack calls in with the paid ones.
- Sell more to existing customers. Retention revenue isn’t subject to the ad auction at all.
None of those require a bigger budget. All of them require better systems.
The number that matters more than budget size
Here’s the reframe that separates shops that grow from shops that just spend: the size of your marketing budget matters far less than your cost per booked job and your return on ad spend.
Two shops can both spend 9% of revenue on marketing. One answers every call, texts every web lead in under a minute, and follows up for two weeks. The other sends after-hours calls to voicemail, replies to form fills the next afternoon, and never follows up twice. Same budget. The first shop books two or three times as many jobs from it. The budget didn’t change — the conversion did.
That’s why the leaks matter more than the number:
- Missed calls are pre-paid leads you throw away. You paid $53–$104 to make the phone ring; letting it go to voicemail after 5pm — when a huge share of HVAC demand actually calls — is lighting that money on fire.
- Slow follow-up loses the job to whoever answered first. Speed to lead is one of the highest-leverage variables in home services; the shop that responds in minutes wins a wildly disproportionate share of bookings.
- No second touch means no second chance. Most leads don’t book on the first contact. Without an automated nurture sequence, you’re paying to acquire leads and then abandoning them.
How to stretch the budget you already have
The homeowner behavior driving all of this is well documented: people research online and lean on reviews before they ever pick up the phone. BrightLocal’s 2025 Local Consumer Review Survey found 71% of consumers read online reviews regularly when looking for local businesses, 74% check at least two review sites, and Google is the platform 83% of them use. And the demand is there to capture — the U.S. heating and air-conditioning contractors industry was worth about $158.4 billion in 2025 per IBISWorld, and the Bureau of Labor Statistics projects HVAC employment to grow 8% from 2024 to 2034, much faster than average, with about 40,100 openings a year. The pie is growing. The question is whether your systems let you take a bigger slice without a bigger budget.
The highest-return moves for most shops aren’t “spend more” — they’re “waste less”:
- Answer every call, day and night. An AI receptionist catches the after-hours and overflow calls that currently go to voicemail, so the leads you already paid for actually turn into booked jobs.
- Respond to web leads in seconds. Automated text-back and self-scheduling close the speed-to-lead gap without you hiring a night dispatcher.
- Turn every completed job into a review. An automated review engine feeds the local SEO and trust signals that lower your blended cost per job.
- Reactivate your customer list. Automated email and SMS to past customers is the cheapest revenue you have — and it runs while you sleep.
Doing all of that inside GoHighLevel is a real build. The alternative is to install a system that already has it wired up for HVAC.
Prefer to have someone run it for you? Our GoHighLevel VAs can build and manage your booking calendars, review engine, and follow-up sequences, and our done-for-you social media service keeps the top of the funnel fed while the snapshot converts the bottom. Either way, the goal is the same: get more booked jobs out of the budget you already set, before you spend a dollar more.
Frequently asked questions
How much should an HVAC company spend on marketing?
Most HVAC contractors should budget 7–10% of revenue on marketing in a normal year, and 10–15% if they're new, growing aggressively, or fighting for share in a competitive metro. That range is anchored in benchmark data — all-industry marketing budgets averaged 7.7% of revenue in 2025 (Gartner) and 9.4% per The CMO Survey, with consumer-facing businesses running higher. Because HVAC is a local, consumer-facing service, aim for the upper half of that band rather than the floor.
What is a good marketing budget for a small HVAC business?
Set it as a percentage of trailing-twelve-month revenue, not a random monthly figure. A $1M shop spending 9% is about $90,000/year, or roughly $7,500/month, all-in — ads plus website, reviews, retention, and software. Newer shops under a few years old should lean toward 12–15% because they're buying a customer base and a review profile they don't have yet, while an established shop with strong reviews and a maintenance-plan base can win on 6–8%.
How should HVAC contractors split their marketing budget by channel?
A defensible starting split for a residential shop: 30–40% to Google Local Services Ads and Google Ads (bottom-funnel demand), 15–20% to local SEO, Google Business Profile and reviews, 10–15% to the website and booking system, 10–15% to Meta/social, 10–15% to email and SMS retention, and 5–10% each to brand/offline and a testing reserve. The key is funding the whole funnel — convert and retain, not just acquire — because retention revenue is the cheapest you have.
What does an HVAC lead cost in 2026?
Channel-level figures come from marketing agencies rather than government data, so treat them as reported ranges. Google Local Services Ads leads run around $53 for home services (SearchLight Digital), Google Search PPC around $104 per lead (WebFX), and Facebook/Meta roughly $35–$150 depending on the offer. Whether those are profitable depends less on the lead price than on your booking rate — the same lead is a bargain if you answer the call and follow up, and a loss if it hits voicemail.
Is it better to increase my marketing budget or improve conversion?
For most shops, improving conversion is the cheaper lever. If you spend $9,000/month and book 25% of your leads, lifting that to 35% is the equivalent of a roughly 40% budget increase — without paying more per click, which now averages $7.85 for home-improvement keywords. Answering every call, responding to web leads in minutes, and following up more than once typically recovers more revenue than raising the budget, because you're capturing jobs you already paid to generate.
Should HVAC shops cut marketing spend in the slow season?
Going completely dark off-season is usually a mistake. The homeowner who books a fall tune-up is the same one who calls you first for an emergency replacement in winter, and re-acquiring attention at peak — when every competitor is bidding — costs more than maintaining a steady presence. Keep a slow-season floor, shift the mix toward retention and reviews, and use the quiet months to test new offers so you're ready when demand spikes.
