HVAC lead math runs on the blend.
HVAC is a big-ticket trade wearing a service-call costume. Repairs pay the light bill — but one replacement can clear $2,000 or more in gross profit, so the lead math runs on the mix, not the average:
fifteen leads
a month's buy, at roughly $51 each in the big industry study
a dozen repairs
plus one replacement in the mix
one replacement
can cover the whole batch before the repairs say a word
That $51 figure is SearchLight's February 2026 average across hundreds of HVAC accounts — the big industry study's number, not mine. The point survives any metro's variation: HVAC owners who track cost per booked job instead of cost per lead make calmer decisions. Your close rate and your replacement mix decide everything here — the audit call fills in both.
Ballpark: $150–$600 repairs · $6,000–$12,000 full system replacements · maintenance plans in the low hundreds a year. The audit uses your book, not averages.
Ranges are market ballparks for context, not client claims.
Ads that breathe with the weather.
Competition and lead flow swell in the first heat wave and the first freeze — which is why HVAC budgets get planned by season, not set once in March. The discipline that wins: Google Verified badge in place, calls answered live even in the crunch, leads marked so ranking holds, reviews landing steadily. (The "Google Guaranteed" language still on many agency sites is out of date — that badge was retired in 2025.)
Junk leads run through Google's automated credit review — about 72 hours, no human dispute channel — so clean setup beats cleanup. And HVAC is in the first wave of the move folding these ads into Google Ads, started August 2026. I manage accounts with that switch in view, because it arrives whether anyone's watching or not.

Reviews sell the five-figure job.
Nobody buys a new system from a stranger. Primary category set to the HVAC category — not "General contractor," where map rank goes to die — then a steady drip of new reviews, owner replies, and reviews that name the job: "new furnace," "AC replacement." Those exact words match the searches that pay. Photos refreshed by season — condensers in June, furnaces in October — sell the right job at the right time.
Posting to the profile? Near the bottom of Google's own ranking factors. That effort goes into reviews instead. How I run the listing →
April and October decide the winter.
The double-peak is brutal: the first heat wave and the first hard freeze each detonate the phones, and the shoulder months in between starve crews. The fix is marketing that books maintenance and replacements in April and October — the months that decide whether winter is payroll or panic.

The website holds the shoulder months: it ranks for tune-ups, maintenance plans, and early-replacement research while the phones are quiet, and every request arrives tagged with its source. How I build sites that rank →
Where's the proof?
The receipts are from my father's drywall company — 52 charged ad leads in July 2026 at $39.89, plus a map listing and website carrying their own weight. HVAC replacement tickets run multiples of drywall's, so the same engine needs fewer booked jobs to pay for itself here — not more.
