HVAC lead generation: how to get more heating and cooling jobs

The cheapest HVAC leads come from customers you already have: maintenance plan members, past customers and the reviews they leave, which feed your Google profile. Paid sources such as Local Services Ads (US and UK) and search ads add volume in heatwaves and cold snaps, and bought leads can fill gaps if you judge them by cost per booked job. Whatever the source, the firm that answers first often wins the job, so missed calls are where most HVAC leads are lost. Below: every lead source compared, what a lead costs, how fast to respond, and what changes in the US, UK and Australia.

Where do HVAC companies get leads?

From your own customers, from Google and from paid sources. The first group costs least per job; the paid ones scale fastest.

SourceHow you payWhat makes it work
Maintenance plan membersFree (part of the plan)Two visits a year, a reminder before each season, a review request after each visit
Past customers and referralsFreeA check-in before peak season, a thank-you after every referral
Google Business Profile and reviewsFree (your time)The right category, a review after every call, replies to all of them
Local Services Ads (US and UK; not listed for Australia)Per leadA strong rating and answering every call
Google Search ads, including in MapsPer clickEmergency and replacement keywords in your real service area
Lead sites and pay-per-lead companiesPer lead or subscriptionReplying in minutes, because many leads are shared

Ranking for free is covered in our guide to local SEO for HVAC, and the full year-round plan, including seasonal ads, in the HVAC marketing plan.

Why are maintenance plans the best HVAC lead source?

Because each member is a lead you already have, twice a year. Every tune-up is a chance to fix a fault, spot an ageing system before it fails and ask for a review, without paying for a click.

  • Repair calls: faults found on a tune-up become booked repairs, with no lead cost.
  • Replacement leads: when a system is old or failing, write it up with photos so the replacement quote is ready when the owner is.
  • Reviews: a same-day review request after each visit keeps new reviews coming in quiet months, which keeps your Google profile fresh for the busy ones.
  • Referrals: members who trust you are the people neighbours ask.
Tip: Don't make the plan price depend on a review or offer a discount for one. Google bans incentives for reviews. Ask every member, the same way, for an honest review.

How much does an HVAC lead cost?

It depends on the source, season and area, so work out your own: divide what a source cost by the jobs it booked. For Local Services Ads, one US agency, 99 Calls, puts the median charged HVAC lead at $72.94, with most between $47.81 and $123.43.

That figure comes from just 6 of its own client sites over 12 months, so treat it as a rough guide, not a market average. Search ads charge per click, so the real cost depends on how many callers your page books. Lead sites set their own prices by trade and area; get them in writing.

Google told some advertisers that from 1 October 2026, missed Local Services Ads calls during business hours are charged as leads when the caller stays on the line more than 20 seconds, and follow-up calls you make to that caller within 15 days are charged once, Search Engine Roundtable reported. Our Local Services Ads guide covers eligibility, ranking and bad-lead disputes.

Should HVAC companies buy leads?

Only as a top-up, and only if they pay per booked job. Bought leads stop the day the budget does; your own customers, reviews and profile keep working.

  • Shared leads: the same homeowner may go to several firms at once, so speed decides who gets the job.
  • Exclusive leads: cost more, but only you get the contact. Ask how they're generated.
  • Bad leads: ask how wrong numbers, out-of-area jobs and duplicates are refunded before you sign.
  • Contracts: check minimum spend, notice period and who owns the customer data.

How fast should you respond to an HVAC lead?

Within minutes during working hours, and with an instant text when you can't pick up. A homeowner with no heat or no cooling rings the next firm, and with Local Services Ads a missed call can now cost you the lead fee as well as the job.

  1. Answer, or text back automatically the moment a call is missed.
  2. Book a visit on the first call or text, with a time window.
  3. After a repair on an old system, send the replacement quote in writing with photos.
  4. Follow up replacement quotes twice in two weeks, then monthly.

How do Google reviews turn into HVAC leads?

They help you get found and get chosen. Google says more reviews and positive ratings can help a business's local ranking, and homeowners comparing firms read them before they call.

18.4

new Google reviews a month at the median HVAC firm in our study, the most of the four trades we measured.

Flexi Local, State of local reviews 2026: 257 HVAC firms' newest Google reviews (254 in the US), checked 26–27 Oct 2026 · 2026

Those were established, well-reviewed firms, almost all in the US, so treat it as the pace of the leaders you're up against, not a target for a newer business. Ask after every service call, tune-up and install, and reply to every review. Fake reviews are illegal in all three countries: the FTC's 2024 rule in the US also bans paying for positive or negative reviews, the DMCC Act bans fake reviews in the UK, and the ACCC says Australian businesses must not create fake reviews or arrange for others to. Google goes further and bans any incentive for a review.

How do HVAC lead sources differ in the US, UK and Australia?

Mainly in which paid channels exist and what drives demand. The basics, your own customers, reviews and fast replies, are the same everywhere.

CountryWhat's different
United StatesLocal Services Ads run for eligible service categories, and 99 Calls' HVAC figures above come from them. Lead sites sell shared and exclusive leads.
United KingdomLocal Services Ads run in the UK too, for the categories Google lists; check heating and cooling is one where you work. In England and Wales, the Boiler Upgrade Scheme gives £7,500 towards an air-to-water or ground source heat pump (£9,000 for eligible off-gas-grid homes, until 31 March 2027), and only MCS-certified installers can apply for it on the customer's behalf, so MCS certification opens a lead stream.
AustraliaGoogle's Local Services Ads country list doesn't include Australia, so search ads, Maps ads and the free map pack do the paid and organic work.

Door-knocking and cold calling are legal in all three countries, within rules on hours, do-not-call lists and cancellation rights; our roofing lead generation guide sets them out side by side.

What should an HVAC company track?

Questions

Something else? Ask us directly.

What is the best lead source for HVAC companies?

Maintenance plan members and past customers usually bring the cheapest jobs, followed by your Google profile and reviews. Add Local Services Ads (US and UK) or search ads for peak weeks, and judge every source by cost per booked job.

Are bought HVAC leads worth it?

They can be as a top-up. Check whether leads are shared or exclusive, how bad leads are refunded and what each booked job really costs.

Do Local Services Ads charge for missed calls?

Google told some advertisers that from 1 October 2026, missed calls during business hours are charged when the caller waits more than 20 seconds. Answer every call or pause the ads when you can't.

Can I offer a discount on a tune-up for a Google review?

No. Google's policy bans discounts, payment or anything else in return for a review. Ask every customer for an honest review instead.
