How much should an HVAC company spend on marketing?
For many established HVAC businesses, 5% to 10% of annual revenue can be a useful starting benchmark, while companies pursuing aggressive growth, geographic expansion or market share may need to invest more.
But treating a percentage as the answer is a mistake.
A $5 million HVAC company trying to maintain its current market position has very different marketing needs from a $5 million company planning to add technicians, enter two new service areas and significantly increase installations.
Your marketing budget should therefore be based on what you’re trying to achieve, what it costs to acquire profitable customers and how much additional business your operation can actually handle.
What Percentage of Revenue Should a Company Spend on Marketing?
Current HVAC industry recommendations vary. BDR suggests approximately 5% to 10% for many contractors, with growth-oriented companies potentially investing around 10% to 12% or more.
That makes percentage-of-revenue useful for benchmarking, but not for making the final decision.
Consider these examples:
| Annual Revenue | 5% Budget | 10% Budget |
| $1 million | $50,000 | $100,000 |
| $2 million | $100,000 | $200,000 |
| $5 million | $250,000 | $500,000 |
| $10 million | $500,000 | $1 million |
Those figures can look substantial until you ask what the business expects that investment to accomplish.
If a $5 million company wants to become a $7 million company, maintaining the same marketing activity that produced its existing revenue may not be enough.
Start With Your Growth Target, Not Your Marketing Budget
Instead of beginning with:
“How much should we spend?”
Start with:
“What are we trying to grow?”
An HVAC company saying it wants 20% growth still hasn’t answered the question completely.
Where will that growth come from?
Residential replacements? Emergency repairs? Maintenance agreements? Commercial contracts? A new service area?
Once the revenue objective is broken into specific commercial opportunities, marketing can be designed around acquiring them.
For example, a company focused on residential system replacements may prioritize high-intent search visibility, Google Ads, local SEO and strong conversion pages.
A company pursuing commercial contracts may need a much stronger Business Development component involving target-account identification, relationship development, outbound activity and strategic partnerships.
Same industry.
Completely different growth strategy.
Know What an HVAC Customer Is Worth
Before deciding whether your marketing budget is too high, understand what a customer is worth.
Suppose you spend $500 acquiring a new customer.
Is that expensive?
If the customer produces a $200 one-time job, absolutely.
If that customer purchases a profitable system replacement and remains with the company for years through maintenance and future services, $500 may be an excellent investment.
This is why cost per lead alone isn’t enough to evaluate HVAC marketing.
A more commercially useful metric is customer acquisition cost:
Customer Acquisition Cost = Acquisition Spend ÷ New Customers Acquired
If you spend $20,000 and acquire 80 new customers, your average acquisition cost is $250.
Then compare that figure with the revenue, gross profit and potential lifetime value those customers generate.
Marketing becomes much easier to evaluate when management understands the economics behind the lead.
Don’t Confuse Advertising Spend With Your Total Marketing Budget
If you’re spending $10,000 per month on Google Ads, that doesn’t necessarily mean your marketing budget is $10,000.
Your total investment may also include:
SEO, website optimization, Local Services Ads, content, email marketing, creative production, analytics, call tracking, CRM systems, internal marketing personnel and external strategic or agency support.
Google currently offers Local Services Ads to eligible HVAC businesses in the United States, making paid search one potential component of an HVAC customer-acquisition strategy.
The important distinction is that media spend pays for access to an audience. Strategy and infrastructure determine what happens after you reach them.
Putting your entire budget into advertising while neglecting conversion, measurement and follow-up can become very expensive very quickly.
Should HVAC Companies Spend the Same Amount Every Month?
Usually, no.
HVAC demand is affected by seasonality, particularly in markets with significant temperature changes.
That doesn’t mean marketing should disappear during slower periods.
It means the job of the marketing changes.
Before peak heating or cooling seasons, investment might support SEO, preventative maintenance campaigns, customer reactivation and building search visibility.
During high-demand periods, more budget may shift toward capturing customers actively searching for immediate service.
Slower periods can support maintenance plans, retention, reputation development and commercial Business Development.
Your annual marketing budget can remain disciplined without forcing every month to look identical.
How Do You Know Whether Your Marketing Budget Is Working?
Don’t stop at impressions, clicks and leads.
For an established HVAC business, marketing performance should increasingly connect to:
Qualified leads → booked appointments → customers → revenue → profit.
Management should understand metrics such as cost per qualified lead, booking rate, close rate, customer acquisition cost, average job value, revenue by source and, where possible, customer lifetime value.
This distinction matters.
One campaign could generate 100 inexpensive leads that rarely convert.
Another could generate 40 more expensive leads that produce significantly more profitable work.
The second campaign may be the better investment.
The goal isn’t necessarily the cheapest lead.
It’s profitable customer acquisition.
When Should an HVAC Company Increase Its Marketing Budget?
Increasing investment makes commercial sense when you can demonstrate that additional marketing is likely to generate profitable growth.
For example, your company may have strong conversion rates, acceptable acquisition costs, available technician capacity, and additional market demand.
That’s a potential scaling opportunity.
But if your website isn’t converting, calls aren’t being answered quickly, lead quality is poor or you can’t determine which channels produce customers, adding more money may simply amplify the problem.

Frequently Asked Questions About HVAC Marketing Budgets
Is 5% of revenue enough for HVAC marketing?
It may be sufficient for an established company primarily maintaining its position. A business pursuing aggressive growth, entering new markets or overcoming weak visibility may require a larger investment.
Is $10,000 a month a large HVAC advertising budget?
Context matters. For a $500,000 company, $120,000 annually represents a major percentage of revenue. For a $10 million company, the economics are completely different. Evaluate the investment relative to revenue, margins, acquisition costs and expected return.
How do I know if my HVAC company is spending too much on marketing?
Look at commercial outcomes rather than the dollar amount alone. If customer acquisition costs are unsustainable relative to the value and profitability of the customers being acquired, something needs to change.
Should an HVAC company cut marketing when business is busy?
Usually not automatically. Turning marketing on only when business slows creates reactive growth. Instead, adjust channels, messages and investment according to capacity, seasonality and future demand.
Build Your HVAC Marketing Budget Around Growth
So, how much should an HVAC company spend on marketing?
Use 5% to 10% of revenue as a starting benchmark, not a commandment.
Then build the actual budget around your growth objectives, customer economics, market opportunity, competition and operational capacity.
A company spending $300,000 with a clear acquisition strategy can outperform one spending $500,000 without one.
And a company spending $50,000 may actually be underinvesting if the business has the capacity and economics to profitably acquire significantly more customers.
The goal isn’t to spend the least possible amount on marketing.
It’s to invest the right amount in the right places to produce measurable, profitable growth.
At One Anomaly, we approach Marketing Strategy and Business Development from that commercial perspective. If your HVAC company is preparing to increase its marketing or advertising investment but isn’t confident how much to spend, where to allocate it or what needs to be fixed before scaling, that is worth determining before committing more money.
