HVAC marketing budgets are harder to set than most trades because demand is not steady. The same campaign that looks expensive in October looks like the best money you ever spent during the first heatwave. Any quote that ignores that pattern is a quote written for a different industry. This guide covers what actually drives the cost, how seasonality should shape the budget, what the first 90 days ought to show, and how to compare two proposals honestly.
What drives the number
- Service-area size and climate. A Brisbane business faces near year-round cooling demand; a Melbourne business runs two distinct peaks and a genuinely quiet shoulder. The wider the area and the more climate zones inside it, the more content and campaign management the plan needs.
- Competition depth. Metropolitan air conditioning searches are contested by established installers, franchise networks and retailers with their own installation arms. Regional centres are usually far cheaper to compete in on both search and paid.
- Repair versus installation focus. Repair demand is frequent, urgent and lower value per job. Installation demand is researched, seasonal and far more valuable. Chasing both properly costs more than chasing one.
- Channel mix. Paid search flexes with the weather and stops when the card stops. SEO is a build cost that keeps producing through the shoulder seasons, which is exactly when HVAC businesses need it most.
- Your starting point. A complete Google Business Profile, a fast site and a working review process reduce the remedial work considerably compared with starting from a brochure site.
Seasonality changes how you budget
Most HVAC businesses budget as though every month is the same, then either run out of budget mid-heatwave or spend heavily through a dead shoulder period. Neither is necessary.
A better approach separates the two components. The management and content work runs at a steady level all year, because organic visibility and profile authority take months to build and must already be in place before the peak arrives. Media spend flexes: heavier through the weeks leading into and through summer and winter demand, lighter through the shoulder seasons where it is redirected towards service plans, maintenance and installation planning rather than emergency repair.
The mistake to avoid is switching everything off when it goes quiet. Installation buyers research well before they buy, and the business that is visible in the quiet weeks captures the quotes that get approved when the weather turns.
Budgeting by business size
One or two vans. The realistic goal is dominating a tight radius for repair and service work, with a small installation pipeline. That means a complete profile, a handful of strong service pages, reviews and a modest, tightly targeted ads budget that lifts during peaks.
Three to eight vans. This is where suburb coverage, split repair and installation campaigns, and a genuine service-plan offer start paying for themselves. Budget needs to support content that wins comparison searches — running costs, sizing, ducted versus split — as well as demand capture.
Larger operations with a commercial arm. Two funnels again: domestic demand capture, plus a slower relationship pipeline for building managers, facilities teams and maintenance contracts. Those need different proof, different pages and separate reporting.
What the first 90 days should show
Ninety days will not win the most competitive installation terms, but it is long enough to prove the work is real. Expect the technical fixes done, service and suburb pages published, the Google Business Profile fully built with categories, brands serviced and photos, a review process running, paid campaigns producing tracked calls with a readable search terms report, and call tracking attributing enquiries to a source.
Leading indicators should be moving too: profile calls, map pack impressions, rankings on lower-competition suburbs and repair terms, and a growing share of enquiries that arrive already knowing which brands you service. If the 90 days lands in a shoulder season, judge the plan on those indicators rather than raw job volume.
Comparing quotes properly
- Month-by-month deliverables, not a list of channel names.
- Asset ownership — website, ads account, tracking and profile in your business name, so leaving does not cost you everything you paid for.
- Whether media spend is inside the fee, which hides both the management cost and the budget actually reaching Google.
- How seasonality is handled — a proposal with a flat twelve-month media plan has not thought about your industry.
- KPIs in writing and a review date, plus contract length and exit terms.
What a sensible plan includes
Whatever the number, the components rarely change. Technical health and speed on the website, because most HVAC traffic is mobile and often urgent. Service pages with real depth on the jobs you want more of, rather than one page listing everything. Suburb coverage written properly for the areas you actually attend. A fully built Google Business Profile with categories, brands serviced and photos. A review process that runs continuously. Paid campaigns split by job type. And tracking that ties a phone call back to the campaign that produced it.
Anything charged for outside that list should have a clear reason attached to it. Social content, video and brand work can all earn their place, but not before the demand-capture basics are functioning.
In-house, agency or a mix
Plenty of HVAC businesses run their own Google Business Profile and review process well, because both are close to the job and easy to build into the workflow. The parts that usually justify outside help are paid search structure, technical site work and the content depth that installation searches demand, all of which need consistent time that a busy operator rarely has in December.
A mixed model works: keep reviews and photos in-house where they belong, and buy the specialist work. Be honest about what will actually get done internally, because half-finished profiles and abandoned content plans cost more than they save.
Where HVAC businesses waste money
Shared lead services that sell the same repair enquiry to three installers. Broad paid campaigns with no negatives, funding people shopping for units at retailers rather than looking for an installer. Thin suburb pages produced by swapping a name into a template. Directory subscriptions with no tracked calls. And switching all marketing off in the shoulder season, then paying peak competition prices to restart from nothing when demand returns.
Making the spend defensible
Measure cost per booked job, split between repair, installation and service plan. Those three have different values and different acceptable acquisition costs, and averaging them hides which part of the business the marketing is actually feeding. Track calls with dynamic number insertion, agree what counts as a qualified lead, and review monthly.
