In August you're turning work away. Two techs out, every slot booked, and somebody calling at 4pm about a condenser that died at noon. By the second week of October the phone has gone quiet enough that you notice it, and the same crew you couldn't staff eight weeks ago is looking for something to do.
Nothing about that is a demand problem. It's a distribution problem — and most HVAC lead spend happens in August, when it's least needed and most expensive.
The four kinds of HVAC lead
People buy "HVAC leads" as though they're one product. They aren't. These four differ in ticket size, margin, urgency and how many other contractors are chasing them.
| Kind | Typical ticket | Urgency | Competition | What it's really worth |
|---|---|---|---|---|
| Emergency service | $150–600 | Same day | Whoever answers | Low margin, high stress — but it's the door to everything below |
| Maintenance agreement | $150–400/yr | None | Almost none | The most undervalued item here. Recurring, and it makes the next changeout yours |
| Replacement / changeout | $7,000–20,000 | Days to weeks | 2–5 quotes | Where the money is. Won on trust and timing more than price |
| New construction rough-in | $8,000–40,000+ | Weeks to months | GC's shortlist | Largest and most plannable — and the only one you can see coming |
Changeout range reflects 2026 national replacement pricing reported by CBS News, which puts a full HVAC replacement between $5,000 and $28,000 nationally, and a standard central AC and furnace replacement in a 2,000-square-foot home at $7,000 to $20,000. Other figures are illustrative — substitute your own market and job mix.
Two things follow from that table.
Emergency calls are a channel, not a business. They pay the week and they cost the most to acquire, because everyone is bidding on the same panicked search at 2pm in July. Their real value is the maintenance agreement you sell on the way out and the changeout you get called about in three years. The same logic governs every paid lead source: judge it on cost per booked job, not cost per lead.
Rough-in is the only one you can plan. A residential changeout announces itself when a system fails. A new-construction mechanical scope exists in a schedule months before anyone needs it priced — which is why it's the only kind of HVAC lead you can pursue on your own timetable rather than someone else's emergency — and it's the kind that shows up in project records before anyone advertises it.
Why the shoulder seasons decide your year
Look at the curve at the top of this page. Two peaks, two troughs — or in Florida and the Gulf South, one long peak and one long shoulder. Either way, the troughs are where profitability actually gets decided.
During peak, you don't have a lead problem. You have a capacity problem, and buying leads in July is buying work you can't staff at the price the market sets when everyone else is also buying. Paid HVAC leads are at their most expensive exactly when they're least useful — worth checking how a provider prices access before you commit to a peak-season contract.
The shoulders are the opposite. April, May, September and October are when your crew has capacity, your competitors have gone quiet, and the customer isn't deciding under duress — which is the only condition under which anyone chooses a $12,000 system on anything other than who could come today.
The catch is the lag. Work booked in October was found in August. A changeout quoted in September was probably a maintenance visit in June. If your pipeline activity tracks your call volume, you'll always be prospecting hardest when you have the least capacity and least when you have the most. Checking what is already in your county costs nothing and takes about a minute.
The practical version: do your lead work in the month before the shoulder, not during it. Whatever you spend in July would go further in May, and the same money buys less competition.
The arithmetic nobody runs
Cost per lead is the wrong comparison across kinds, because the tickets aren't remotely alike. The number that settles it is what you spend to book a dollar of revenue.
| Emergency service lead | Rough-in project record | |
|---|---|---|
| Cost to acquire one | $85 | $25 |
| Reach rate | 60% | 45% |
| Close rate on contact | 50% | 20% |
| Leads per booked job | 3.3 | 11.1 |
| Acquisition cost per booked job | $280 | $278 |
| Average ticket | $400 | $14,000 |
| Cost per $1,000 of booked revenue | $700 | $20 |
Illustrative. Lead prices, reach and close rates are your numbers to substitute — the ticket figures follow the table above.
Look at the last two rows. Acquisition cost per booked job is almost identical, which is why per-lead comparisons make these look interchangeable. They aren't. One books $400 of work, the other books $14,000, and the gap in cost per dollar of revenue is roughly thirty-five to one.
That doesn't mean stop taking emergency calls. It means stop judging the two by the same yardstick, and stop being surprised when a July lead budget aimed at same-day work produces a busy month and a thin margin. Run this with your own reach and close rates before your next renewal — the ranking rarely survives contact with real numbers.
Where HVAC leads actually come from
Each kind of work arrives through a different door, and most HVAC contractor leads are mispriced because the buyer never specified which door. Matching source to kind is most of the job.
Emergency and service
Local search, almost entirely. A complete Google Business Profile with accurate hours, a service area set properly and a habit of answering reviews will outperform anything you can buy for same-day work, because the search happens on a phone with the AC already off. Paid search works here too and is priced accordingly — HVAC carries some of the highest cost-per-click in the trades — which is why the free sources deserve exhausting first.
Maintenance agreements
Your own customer list, and almost nowhere else. Every service call and every changeout is an opportunity to sell one, and nobody advertises their way into this. It's the cheapest revenue in the business and the most commonly left on the table, and it costs nothing to sell — see the free sources worth running first.
Replacement and changeout
Three doors: your existing customers with aging equipment, referrals from people whose systems you've maintained, and homeowners actively shopping — the last being the most competitive and the most price-driven. Age of equipment is the strongest signal there is, and it's the one thing your own records already tell you. For everything outside your list, where the data comes from decides whether it's worth acting on.
New construction and rough-in
General contractors and builders, which means relationships rather than listings. The mechanical scope on a residential build gets awarded from a shortlist, and being on that shortlist is a function of who knew about the project early. This is where arriving before the bid list does the most work, and where permit records are useful, because a residential build under way is visible before the mechanical scope is priced. Bid boards reach you later than this, which is the whole distinction.
Worth reading alongside this: the eight genuinely free sources of contractor leads, several of which are stronger for HVAC than for most trades because so much of the work is repeat and referral-driven.
What to check before paying for HVAC leads
HVAC is one of the most expensive trades to buy leads in, and most HVAC lead generation providers sell all four kinds under one label. These questions are worth asking before money moves.
Ask question one first. If a provider can't tell you which of the four kinds they're selling, the other six don't matter.
Where TigerLeads fits
We cover one of the four, and it's worth being clear about which: new construction and rough-in work. We don't send emergency service calls, and we won't tell you a condenser died this afternoon.
What's there is project activity built from building permit records — gathered automatically and reviewed by a person before release, across 39 states and more than 300 jurisdictions, updated daily. For an HVAC contractor that means visibility of residential and light commercial builds under way in your county, including who else is already on the job.
The specifics, all checkable before you spend anything. Every record carries 20 data points, five visible free — permit type, job cost, project description, county/city and state — so you can tell a $40,000 build from a water-heater swap before committing. Unlock cost is shown before you confirm and is scored on record quality rather than charged flat. A maximum of five contractors of the same trade can access any given lead, with remaining availability visible up front. And it's free to start with no credit card, which matters in a trade where the standard offer is an annual contract.
On seasonality specifically: because you pay per unlock rather than per month, spend can follow the curve instead of fighting it. Heavy in the months before the shoulders, light in July when you couldn't staff the work anyway.
Whether that's useful depends on your job mix. If you're primarily a service and changeout shop working from your own customer list, start with the free sources — they'll outperform anything paid on that kind of work. If rough-in is a meaningful share of your revenue — or you want it to be — how the records are sourced and verified is the part worth reading first.

Frequently asked questions
What are HVAC leads?
Potential heating and cooling jobs, covering four different kinds of work: emergency service calls, maintenance agreements, replacement and changeout work, and new construction rough-in. They differ enormously in ticket size, urgency and competition, so buying "HVAC leads" without specifying which kind usually means buying the cheapest to produce.
How do I get more HVAC leads?
Match the source to the kind of work. Local search and a complete Google Business Profile for emergency and service; your own customer list for maintenance agreements and changeouts; general contractor relationships and permit records for new construction. Doing this in the months before your shoulder seasons matters more than how much you spend. The eight free sources are the place to start.
Are paid HVAC leads worth it?
They're worth it when cost per booked job beats what the same money produces elsewhere, which depends heavily on which kind you're buying. Emergency leads are expensive and won by response speed. Rough-in leads are cheaper per dollar of revenue but need a longer runway. Track cost per booked job by kind for one season before scaling anything, then compare against what access actually costs.
When is the best time to buy HVAC leads?
The months before your shoulder seasons — roughly February to March and July to August in most climate zones. Peak demand fills itself from inbound calls and lead prices are highest exactly then. The work you book in October was found in August.
How do I find new construction HVAC work?
Through general contractors and builders, since the mechanical scope is awarded from a shortlist rather than advertised. Being on that shortlist depends on knowing about the project early, which is what permit and preconstruction records are useful for — a residential build is visible before the mechanical scope gets priced. Timing by delivery method covers when that head start applies.
What's the most valuable kind of HVAC lead?
By ticket size, new construction rough-in. By return on effort, the maintenance agreement, because it's recurring, has almost no competition, and it makes the eventual changeout yours by default. Emergency calls have the worst economics as standalone jobs but function as the entry point to both.
