HVAC Leads: What They Cost and What You Can Afford to Pay

HVAC is one of the few home trades where a three-figure lead price is comfortably affordable. A replacement averages $7,500, inside a $5,000 to $12,500 range, against a home improvement benchmark of $90.92 per lead. The risk is not the price. It is everything after it.

What can you actually afford to pay for an HVAC lead?

Start with the job, because HVAC sits at the opposite end of the scale from most trades sold alongside it.

A full HVAC unit replacement runs $5,000 to $12,500, with a national average of $7,500. Within that, the equipment choice moves the number a long way: an air source heat pump at $4,500 to $8,000, a gas furnace at $3,800 to $10,000, central air at $3,900 to $7,900. Labour is typically around $1,500, with permits a further $250 to $400.

Now the benchmark. Published 2026 search advertising figures put home and home improvement at $90.92 per lead, from an $8.33 click and an 8.05% conversion rate, against $66.69 across all industries.

Put those together and the arithmetic is unusually forgiving. Even at a poor close rate of one in ten, a lead at the home improvement average costs a low three-figure sum per signed job against a ticket averaging $7,500. Compare that with a trade where the whole job is a few hundred dollars, such as the one described in what gutter leads are worth, and the difference in what you can rationally bid is enormous.

The ceiling still comes from your own numbers, not from the national average:

• Your average installed ticket, split between replacement and repair, because they are different businesses.
• Your close rate from inquiry to signed install, measured on signed work.
• The share of gross margin you are willing to spend acquiring a job.

Multiply the first two, take the share you can afford, and most quoted lead prices answer themselves.

Why is a repair lead not the same product as a replacement lead?

Because the two differ by a factor of ten in value and arrive looking identical.

A no-heat call in January and a planned system replacement both enter as "HVAC lead". One is a diagnostic visit worth a service fee. The other is a $5,000 to $12,500 install. If your seller prices both the same, you are subsidising one with the other, and the mix decides whether the source works.

Ask every seller for the mix, in writing, and for the right to see it monthly. A source that shifts from replacement to repair over a season has materially changed what you are buying without changing the price.

The repair call is still worth having, because it is the cheapest route to a replacement eighteen months later. It is simply not worth the same money today.

How does seasonality change the maths?

More sharply than in any adjacent trade, and it is the single biggest reason HVAC lead budgets misfire.

Demand arrives in two spikes: the first sustained cold and the first sustained heat. Both are weather events, not calendar ones. In those weeks every contractor in the area bids for the same homeowner, auction prices rise, and the inquiries that arrive are urgent and already decided. Between the spikes, the same spend buys planned-replacement conversations that convert more slowly and compete harder on price.

Three consequences worth building into the plan:

1. A fixed monthly lead volume is wrong in both directions. It overbuys in the shoulder months and runs out in the fortnight that matters.
2. Capacity, not budget, is the binding constraint in a spike. Buying more inquiries than you can install turns a marketing decision into a backlog, and the backlog shows up as slow callbacks on leads you already paid for.
3. Judge each source by month, not by year. An annual cost per signed job hides a strong January inside a weak April.

The practical version is to pace volume against installation capacity and to let the budget flex with the weather rather than the calendar.

What does the high ticket let you buy that other trades cannot?

Exclusivity, speed of delivery, and verification. All three cost money per inquiry, and in HVAC all three are usually worth it.

A shared inquiry reaches several contractors within minutes. In a trade where the homeowner is cold and wants someone today, position matters more than price, and arriving third is close to arriving last. The full comparison on cost per signed job is in shared against exclusive leads, and the conclusion there tilts further toward exclusivity as the ticket rises.

Be precise about what you are buying, though. "Exclusive" is used loosely enough that three questions are worth asking in writing: is the inquiry ever resold, after what period, and does the seller run its own brand against the same search terms. Those sit alongside the rest of the answers a lead seller should put in writing.

The same reasoning applies to how you buy. Paying per lead moves the media risk to the supplier at a higher unit price, which a $7,500 average job absorbs comfortably. The structural trade is set out in pay per lead against pay per click.

Where does the money actually leak?

Not in the lead price. In the gap between the inquiry and the install.

Research on online inquiry handling found that most companies respond far too slowly to web leads. In HVAC the penalty is sharper than the research implies, because an emergency call is bought in the time it takes to find a second phone number. A contractor paying a premium for exclusive leads and answering them in two hours has bought position and then given it away.

Four leaks, in the order they usually cost the most:

• Slow first contact. The fix is a process, not more budget, and it is laid out for the neighbouring trade in the speed to lead routing guide.
• No in-home assessment booked on the first call. A replacement is not sold over the phone, and a callback to arrange the visit loses a share of them.
• No financing conversation. At $5,000 to $12,500, the obstacle is frequently the lump sum rather than the price.
• No follow-up on a quote that did not close. Replacement decisions stall for weeks and then restart with whoever is still in the inbox.

Each of those costs more than the difference between a good lead price and a bad one, which is why cost per signed job is the only number worth managing.

How should you judge a lead source in HVAC?

On cost per signed install, by month, with the repair and replacement mix shown separately.

That is harder than it sounds, because it needs three things on your side that nothing in the campaign can supply:

1. A persistent identifier on every inquiry, so an install can be traced back to its source months later.
2. Stage-by-stage records, from first contact through assessment booked, quote issued, and job signed.
3. Someone who fills them in, which is the step that usually fails.

Run a trial for a full season rather than a month. HVAC decisions stretch, and a source judged in four weeks is judged on its repair mix rather than its replacement mix. Hold your own process constant for the whole test: same people, same answer time, same quoting approach. If you answer the new source faster because it is new, you are measuring your own enthusiasm.

If you would rather buy a measured outcome than a price per inquiry, that is the model behind performance-based HVAC lead generation, where the supplier carries the media risk instead of you. The same question applied to agency fees is covered in how to choose a marketing agency, which is written for plumbers but is identical in structure for HVAC.

Does the first job set the real ceiling?

No, and treating it as though it does is why many HVAC contractors underbid for leads they could afford.

An install is the start of a relationship rather than a transaction. A system put in this winter brings a maintenance visit next autumn, a repair at some point in its life, and a replacement conversation when it reaches the end of it. A contractor who holds the maintenance plan is also the first call when something fails, which is the cheapest lead anyone ever gets.

That changes the arithmetic in two ways worth being explicit about.

It raises what a replacement lead is worth. If a meaningful share of installs become maintenance customers, the value of winning one is the install plus whatever the relationship produces afterwards. The install ticket of $5,000 to $12,500 is the floor of that number, not the whole of it.

It makes the repair lead a different purchase. A diagnostic visit that produces a maintenance signup is worth considerably more than the service fee suggests, which is the argument for buying repair inquiries at a sensible price rather than refusing them.

Two cautions, because this reasoning is easy to overdo. Only count the follow-on value you can actually evidence from your own records; a hoped-for replacement in twelve years is not a number you can bid against today. And remember that the follow-on only happens if somebody runs the retention process. A maintenance plan nobody calls to renew is a line in a spreadsheet, not revenue.

The practical test is simple. Look at the installs you won two years ago and count how many are still customers. That proportion, applied to your install ticket, is the honest ceiling to bid against, and it is almost always higher than the one contractors use.

What should you check before buying HVAC leads?

Six questions, ordered by how much money they save.

• What is the replacement to repair mix, and can you see it monthly? This decides the value of everything else.
• Is the inquiry exclusive, and for how long? Get the resale window in writing, not the word.
• How fast is delivery, and by what method? A lead that arrives in a nightly batch cannot be called in five minutes, whatever your process.
• Does the lead carry the system type and the age of the existing unit? Those two fields separate a quote from a guess.
• What is the credit policy, with a window and a proof standard? A policy you cannot practically use is decoration.
• What is the service radius? A $7,500 job carries a longer drive than a service call does, but not an unlimited one.

A seller who answers all six without hesitation is describing a product. One who answers in adjectives is describing a hope.

What else do HVAC contractors ask?

What is a reasonable cost per lead for HVAC?

Higher than most trades can justify, because the job is larger. Published 2026 search figures put the home improvement average at $90.92 per lead, and against a $7,500 average replacement that is affordable at close rates most contractors already achieve. Set your own ceiling from ticket multiplied by close rate rather than from the benchmark.

Are exclusive HVAC leads worth the premium?

Usually, and more so than in low-ticket trades. The premium is a small share of a four-figure job, and the gain is position in a decision where the first contractor to arrive often wins. It stops being worth it if you cannot answer quickly, because then you are paying for an advantage you do not use.

Should you buy repair leads or only replacement leads?

Both, but price them separately and track them separately. Repair work pays for itself immediately and seeds replacements later. The mistake is paying a replacement price for a repair mix, which happens quietly when the seller is not asked for the split.

How long should an HVAC lead trial run?

A full season, covering at least one demand spike and the quieter weeks either side. A one-month trial measures the weather rather than the source.

What single number should you track?

Cost per signed install, by source, by month, with repair and replacement shown apart. Cost per lead conceals the mix, the seasonality and your own response speed, and in HVAC all three move the result more than the lead price does.
