How Much Should HVAC Contractors Spend on Marketing?

Quick answer: Most HVAC contractors should invest 5 to 10 percent of total revenue in marketing. Established companies protecting their position sit near the low end. Companies in active growth mode spend 10 to 12 percent or more. The right number depends on your growth goal, your market, and how profitable your jobs are.

Below is the full HVAC marketing budget article covers how to set your marketing budget, split it across marketing channels, and measure the return on investment.

What Percentage of HVAC Revenue Should Go to Marketing?

Every HVAC owner asks the same question. How much is enough, and how much is too much?

The honest answer is that marketing is not a cost. It is the engine that fills your schedule. The real question is not “how little can I spend,” but “what return does each dollar produce.”

As a starting benchmark, healthy HVAC companies invest 8 to 12 percent of total revenue into marketing during growth phases. Mature companies with strong repeat business can hold nearer to 5 percent and still grow.

The trap is spending in panic. Owners cut marketing when they are busy, then scramble when the phone goes quiet. A steady budget that runs every month beats a stop-and-start one every time.

Set Your Marketing Budget by Business Stage

The right budget changes as your business grows. Match your spend to your stage.

Startup and early growth (under $1M revenue). Spend on the high end, 10 to 15 percent. You are building awareness and a customer base from scratch. Every new customer compounds into future repeat work.

Scaling (between $1M and $3M). Hold 8 to 12 percent. Focus the budget on the channels already producing booked jobs, and reinvest the wins.

Established ($3M and up). A 5 to 8 percent budget often sustains growth. Repeat customers and referrals carry more of the load, so spend protects your position and feeds new markets.

These are starting points, not rules. An HVAC business entering a new service area spends more. A company at capacity spends to protect margin, not to chase volume.

How to Allocate Your HVAC Marketing Budget

A budget without a plan gets wasted. Split your spend across the channels that actually drive HVAC leads.

Here is a sensible starting allocation for a typical residential HVAC business:

• Local search and Google Business Profile (25 to 30%). The highest-return channel for a local company. Fund profile management, reviews, and local SEO.
• Paid search and Local Services Ads (30 to 35%). Capture homeowners at the moment of need. LSA and PPC produce fast, trackable leads.
• Website and content (15 to 20%). Your site converts the traffic everything else earns. Strong service pages and helpful content build rankings over time.
• Existing-customer marketing (10 to 15%). Email and text to past customers is the cheapest revenue you own. Fund tune-up reminders and seasonal offers.
• Reputation and reviews (5 to 10%). Automated review requests after every job compound into rankings and trust.

That existing-customer line deserves more weight than most owners give it. The Air Conditioning Contractors of America reports database marketing returns $8 to $12 per dollar. New-customer acquisition returns just $3 to $4. Yet most HVAC contractors spend 70 to 80 percent of their budget chasing new customers.

Timing matters as much as mix. The ACCA recommends front-loading 60 to 70 percent of spend into your peak four to six months, when acquisition costs are lowest. A flat spend across twelve months leaves money on the table.

Adjust the mix to your market. The principle holds: fund the channels that produce profitable booked jobs, and cut the ones that only produce activity.

SEO vs. PPC: Where Should the Money Go?

Owners often treat this as either-or. The strongest HVAC companies run both, because they do different jobs.

PPC and Local Services Ads buy you new HVAC leads today. The moment you need to fill the schedule, paid search delivers. The downside is that leads stop when spending stops.

SEO and your Google Business Profile build an asset that pays off for years. The downside is that it takes months to mature. Start it early and keep at it.

The smart play is paid search for immediate flow and SEO for long-term, lower-cost leads. Together they lower your blended cost per lead over time.

Don’t Forget AI Search

A new channel now sits alongside Google. Homeowners ask ChatGPT, Claude, Google AI Mode, and Perplexity to recommend a contractor.

This shift is already large. Recent industry research shows about 37 percent of consumers now begin their search with an AI assistant instead of Google. BrightLocal puts AI use for finding local services at 45 percent, up from 6 percent a year earlier.

The payoff is profit, not just reach. Semrush data shows AI-referred traffic converts at 4.4 times the rate of standard search. The catch is that AI recommends only about 1.2 percent of local businesses, so the content has to earn the citation.

These tools cite businesses with clear, authoritative, well-structured content. Budgeting for content that answers real homeowner questions now earns visibility in the fastest-growing search channel of 2026.

How to Measure Your Marketing ROI

A budget only works if you measure it. Track these numbers every month.

Cost per lead (CPL). HVAC CPL in 2026 runs $70 to $150, and up to $250 in competitive markets. Know yours by channel.

Cost per booked job. A channel with cheap leads that never book is not cheap. Measure the cost of an actual job, not a phone call.

Customer acquisition cost vs. lifetime value. A new customer worth thousands over a decade justifies a higher acquisition cost than a one-time repair.

Channel attribution. Use call tracking to tag every lead to its source. Within six months you will know exactly where to put the next dollar.

When you measure this way, marketing stops being a guess. It becomes a profit decision.

The Budget Is Only Half the Battle

Here is what most marketing-budget conversations miss. The money that brings in the call is wasted if the call is handled poorly.

As Angela Kiel of BDR puts it:

“You could have the best website in the world, but if your internal staff doesn’t know how to answer the phone, upsell accessories, or follow up with happy calls, you’re driving your profits down the line. The phone call isn’t the revenue, it’s the relationships and actions after the call that generate true growth.”

Your booking rate, your average ticket, and your follow-up turn marketing spend into profit. Train your CSRs and technicians with the same seriousness you bring to the ad budget.

Build a Marketing Budget That Drives Profit

The right HVAC marketing budget is not a fixed number. It is a percentage of revenue, matched to your growth stage. You allocate it to profitable channels and measure it every month.
