How SEO, Google Ads, LSAs and review systems fit together for HVAC contractors - budget split, seasonality and the metrics that matter. This guide is written for HVAC companies building a full-funnel marketing programme, and everything below comes from work we do on live accounts rather than recycled theory. Skim the sections, take the numbers as starting benchmarks for your own market, and treat the checklist items as a work plan you can hand to your team or your agency this week.
What it costs
A working HVAC mix is usually 40% paid (Google Ads + Local Services Ads), 35% SEO and local, 15% site and CRO, 10% reviews and retention. In competitive US metros total media plus management commonly runs $6,000-$20,000 per month during peak season.
Treat every range above as a starting benchmark, not a quote. Competition in your specific market, the current state of your website, how much production capacity you already have in-house, and how aggressive your growth target is will all move the number. The useful exercise is to work backwards from revenue: what is one additional customer worth, how many do you need per month to justify the spend, and does the plan on the table plausibly produce them?
How long it takes
Paid produces calls within days, so it funds the programme while SEO compounds over months 3-6. Plan a budget curve, not a flat spend: 1.5-2x your baseline in the four weeks before and during peak demand.
Two things reliably compress timelines. The first is production volume: more genuinely useful pages and more consistent execution per month means faster results, which is why budget and speed are linked. The second is starting condition - a site with clean technical foundations and existing authority moves much faster than a new domain. Be honest about which one you are, then set expectations accordingly with whoever signs off on the budget.
What actually works
Run Local Services Ads and Search together. LSAs capture the highest-intent 'near me' calls; Search covers brand, service and competitor terms LSAs cannot.
Separate emergency from replacement campaigns. Emergency traffic wants speed and phone numbers; replacement wants financing, brands and quotes.
None of these are clever. They are the boring fundamentals executed at unusual quality and consistency, which is what separates programmes that compound from programmes that plateau after one quarter.
Build a maintenance-plan offer and put it behind every channel. It converts one-time repairs into recurring revenue and lowers effective CAC dramatically.
Use weather and season as a bidding signal: raise budgets on heat waves and cold snaps, and pause replacement campaigns when technicians are already booked out.
Mistakes that cost the most
Flat-spending year round. HVAC demand is seasonal; the budget must be too.
Sending every ad to the homepage. Emergency callers abandon a homepage carousel in seconds.
Ignoring after-hours. If nobody answers at 9pm, the paid click was a donation to your competitor.
Every one of these is common enough that we expect to find at least two of them in any audit. Fixing them costs almost nothing compared with the spend they waste, so they belong at the top of the work plan rather than in a backlog.
Your next 90 days
Weeks 1-2: instrument everything first. Tracking, call tracking where relevant, a conversion definition that finance would accept, and a baseline you can defend later. Skipping this step is the single most expensive shortcut available, because without a baseline you cannot prove anything worked.
Weeks 3-8: ship the highest-leverage items from the 'what actually works' list above, in priority order, one at a time so each change stays attributable. Resist the urge to rebuild everything at once - it feels productive and it destroys your ability to learn.
Weeks 9-12: build the compounding layer - content cadence, review velocity, link acquisition, experimentation - and set a monthly review with a fixed agenda. HVAC accounts that separate emergency and replacement intent into different campaigns and landing pages routinely cut cost per booked job by a quarter or more.
