How Much Should Home Services Contractors Spend on Marketing?

A healthy home services marketing budget is 5 to 10 percent of revenue. Contractors in aggressive growth mode — or newer shops without a referral base — often run 10 to 15 percent; established businesses riding repeat and referral work can sit near 5 percent or below.

Marketing % of Revenue = Marketing Spend ÷ Revenue

How Do You Calculate It?

Take everything that goes into generating and nurturing leads — paid search, paid social, direct mail, radio, truck wraps, review-platform fees, your website and SEO retainer, even the labor cost of a part-time marketing coordinator — and divide it by trailing revenue for the same period. Most shops run this monthly and again on a rolling 12-month basis, because a single slow month (or a single big trade-show sponsorship) can make one month's ratio look misleading. The 12-month view smooths out seasonality and one-off spend so you're comparing like to like.

Two things trip owners up here. First, "marketing spend" quietly grows to include sales commissions, CRM software, or a general manager's salary because that person "does some marketing." Keep the numerator honest — spend that exists specifically to generate or convert leads — or the ratio stops meaning anything. Second, use the right revenue base: trailing 12-month revenue, not last month's revenue, unless you're deliberately checking a single aggressive campaign against the month it ran in.

What Should You Actually Watch — Spend Or Return?

The percentage is the guardrail, not the goal. What matters is whether that spend returns. Two numbers tell you:

• Cost per lead — a healthy CPL runs $50–150; if yours is far above that, the channel or the offer is the problem, not the budget.
• CAC and LTV:CAC — acquisition cost around $200–350 with a lifetime-value-to-CAC ratio above 3:1 means growth is paying for itself.

A contractor spending 12 percent of revenue at a 5:1 LTV:CAC is not overspending — they are buying profitable growth. A contractor spending 6 percent at a 1.5:1 ratio is wasting money even though the percentage looks conservative. Spend follows return, not a rule of thumb.

Here's a simple worked example to make that concrete. Say a shop does $2M in annual revenue and spends 8 percent — $160,000 — on marketing. If that budget produces leads at $100 CPL, that's 1,600 leads a year. At a typical close rate, a chunk of those become jobs, and if the resulting LTV:CAC clears 3:1, the 8 percent figure is doing exactly what it should. Cut that same $160,000 budget to 5 percent to hit some "target" and the shop may simply generate fewer leads at the same efficiency — slower growth, not better economics. The percentage didn't get healthier; the pipeline got smaller.

Why Does My Marketing Percentage Look Too High Or Too Low?

A handful of factors push the ratio around, and none of them mean you're doing it wrong:

• Business age and referral base. A 15-year-old shop with a deep base of repeat customers and referrals can spend 5 percent and still fill the schedule. A two-year-old shop with no reputation yet has to buy every lead, so 10–15 percent is normal, not wasteful.
• Growth ambitions. Holding steady at current revenue takes far less spend than trying to grow 20–30 percent a year. If you're budgeting for growth, budget for the marketing percentage that growth actually requires.
• Service mix. Emergency-heavy trades (plumbing, some HVAC repair) often convert paid search efficiently because the buyer is searching right now. Planned-purchase categories (replacement systems, remodels) usually need more nurture spend and a longer funnel, which raises the ratio.
• Market competitiveness. A crowded metro with five other well-funded competitors bidding on the same keywords pushes cost per click — and therefore the percentage — up. A less contested rural market can hit the same lead volume for less.
• Seasonality. HVAC in particular can see marketing spend concentrate ahead of a hot or cold season. A snapshot taken mid-ramp will look heavier than the trailing-12-month number.

None of these are excuses to ignore the ratio — they're context for reading it correctly before you cut a budget that's actually working.

What Does "Good" Look Like At Different Sizes?

Situation	Typical marketing %
Established, referral-heavy	~5%
Steady growth	7–10%
Aggressive growth / new market	10–15%

Revenue size interacts with all of this too. A $500K shop often needs to spend at the higher end of the range just to generate enough lead volume to keep techs booked — fixed costs (a website, review management, basic paid search) don't shrink much just because revenue is smaller. A $5M+ shop with an established brand and a maintenance-agreement base can often run leaner, because maintenance agreement penetration generates recurring, low-cost-of-acquisition revenue that doesn't need fresh marketing dollars behind it every month. The dollar amount grows with revenue; the percentage often shrinks.

These are general home-services ranges; the right number depends on your growth goals and margins.

Common Mistakes That Blow Up A Marketing Budget

The most common mistake is judging marketing by the invoice instead of the booked jobs it produced. An owner sees a $12,000 monthly ad bill and reacts to the size of the number, not what it returned. Tie every dollar to leads and booked revenue and the "how much should I spend" question answers itself.

A few other patterns show up repeatedly in home services shops:

1. Cutting spend during a slow month. Slow months are often when CPL is cheapest (less competition bidding) — cutting then is the opposite of what the data supports.
2. Chasing volume over quality. More leads at a worse close rate can raise cost per booked job even while CPL looks fine. If your estimate-to-close rate is weak, more marketing spend just buys more unclosed estimates.
3. No attribution. Without tracking which channel a booked job came from, owners keep funding the loudest channel instead of the best one.
4. Treating the percentage as a target instead of an output. The ratio should fall out of a return-driven spend decision, not be set first and backed into.

How Does Marketing Spend Connect To Other Metrics?

Marketing percent of revenue doesn't live on its own — it's upstream of almost everything else you track. Cheap, well-targeted leads still need a strong close rate to turn into jobs, and booked jobs still need healthy gross margin and net profit margin to actually contribute to the bottom line. A shop can nail its marketing percentage and CAC and still struggle if technician utilization is low or callback and rework rates are eating the margin those jobs were supposed to produce. Marketing spend buys opportunity; the rest of the operation decides whether that opportunity turns into profit. Owners who review this number in isolation, without walking it through close rate and margin, tend to either panic over a "high" percentage that's actually healthy or stay comfortable with a "low" one that's quietly starving growth. A weekly operating review that puts marketing spend, CPL, CAC, close rate, and margin on the same page each week is the fastest way to catch either problem early.

If you're not sure your business even has visibility into these numbers today, that's worth naming directly rather than guessing at a target percentage — you can't manage what you can't see. Free resources like the SBA and SCORE publish general guidance on budgeting and cash flow planning for small businesses, and trade groups like ACCA offer benchmarking resources specific to HVAC contractors if you want an industry-specific reference point alongside your own numbers.

Frequently Asked Questions

How much should an HVAC company spend on marketing?

Most spend 5 to 10 percent of revenue — more when growing aggressively or entering a new market, less when demand is driven by repeat and referral customers. The right number for your shop depends on how much of your pipeline already comes from repeat work versus paid acquisition, and how aggressively you're trying to grow this year.

Is 10 percent of revenue too much to spend on marketing?

Not if it returns. Ten percent at a 4:1 or 5:1 lifetime-value-to-CAC ratio is profitable growth. The percentage only sizes the bet; CPL and LTV:CAC tell you whether it is paying off. A lower percentage with a weak ratio can waste more money than a higher percentage that's working hard.

What marketing metrics should contractors track?

Cost per lead, cost per booked job, customer acquisition cost, and the LTV:CAC ratio — plus which channels actually book jobs, not just generate calls. Reviewing these alongside close rate and gross margin, rather than the marketing percentage alone, is what turns the number into a decision you can act on.

Should my marketing percentage change as my business grows?

Usually, yes — and usually downward. Early-stage and fast-growing shops often need to spend at the higher end of the range simply to generate enough lead volume, since there's little repeat or referral business yet to lean on. As a shop builds a maintenance-agreement base and a referral engine, a smaller percentage can sustain the same lead volume, freeing dollars for margin instead of acquisition.

How do I know if I'm underspending on marketing?

The clearest sign is a schedule with open capacity next to techs who could be booked. If cost per lead and LTV:CAC both look healthy and you still have unfilled capacity, that's a case for spending more, not less — you're leaving profitable growth on the table by holding the percentage artificially low.
