HVAC lead cost varies with the purchasing model, market and work requested. Current evidence includes a $54.99 organic HVAC lead rate within a 99 Calls package and a $51 HVAC LSA cost reported in SearchLight’s February 2026 dataset. Neither is a universal all-in price for an HVAC inquiry in your ZIP codes.
Compare the complete quote, then calculate cost per attended assessment and completed job. A low contact price does not establish whether your office can reach the homeowner or your crew can profitably serve the request.
Disclosure: theBuildd publishes this guide and sells exclusive residential HVAC opt-ins, with optional monthly dispatching. Figures below are published terms, attributed observations or explicitly labeled examples.

Sources: theBuildd pricing, 99 Calls HVAC page, 99 Calls pricing, and SearchLight’s LSA dataset. The source check is current; the SearchLight observation period remains February 2026.
Google’s Local Services lead documentation says prices can vary by location, job type, lead type and bidding mode. It does not provide a fixed national HVAC rate for your purchase.
Include the full package behind a per-lead rate
99 Calls’ pricing page lists Growth at $399/month plus $399 setup, an organic per-lead charge and a Google Ads service fee of 15% of spend. The HVAC page’s FAQ uses different wording, saying $399 or 15% of spend for Google Ads management. Have the proposal reconcile that difference; do not silently choose whichever reading makes the budget look lower.
Its HVAC page also publishes $164-$414 for Google Ads and $39-$111 for Local Services Ads. The provider describes these as 10th-90th percentile cost observations across businesses over the prior 12 full months. They are not fixed rate cards or forecasts, and the complete management/media cost needs to be clear in a quote.
For other provider models, use the HVAC lead company comparison. Mark any exact local amount unavailable until the seller supplies it. A third-party price estimate is not that seller’s current offer to you.
Carry CPL through a consistently defined booking rate
SearchLight reports $51 CPL and a 44% book rate for its HVAC row. Dividing $51 by 0.44 produces $115.91, or about $116 per booked appointment under those reported inputs.
That is a calculation from a particular dataset. It does not establish your cost per accepted replacement or completed paying job. SearchLight separately reports later paying-customer outcomes, so those stages must stay distinct.
For your own records, use either source spend divided by booked appointments or CPL divided by the booking rate, provided the inputs refer to the same group. Use 0.20 for a 20% rate, not 20. If the two methods disagree, check the denominator, fees and attribution period.
The cost per booked job guide explains how to define the event. A service appointment, attended replacement assessment and completed installation should not share one label in a source comparison.
Keep specialty lanes visible as well. The HVAC maintenance lead guide tracks completed tune-ups and agreement interest separately, while the mini-split lead guide carries ductless inquiries through held assessment and proposal.
Separate repair, replacement and accessory work
Your acquisition ceiling depends on the contribution a completed job leaves after direct costs. That can differ substantially between service and installation work. Keep these groups visible:
- Diagnostic and urgent repair requests.
- Planned maintenance.
- Furnace or AC replacement interest.
- Heat pumps and other accepted system types.
- Indoor air quality and accessory inquiries.
Use the furnace replacement checklist and AC replacement checklist when those are the purchases you want. A no-heat or no-cool symptom is not proof that a replacement is needed. Keep urgent service in the emergency HVAC lead workflow instead.
Track what the technician recommends after assessment. A repair outcome can be useful service work without counting as a replacement win.
A flat monthly plan still needs actual results
On theBuildd base plans, your office qualifies the opt-ins. Optional monthly dispatching adds our callers and a live transfer or booked appointment handoff. The trial and weekly options exclude dispatching. Review the HVAC offer to confirm work and territory before selecting a plan.
For illustration, assume $3,000 in monthly source spend and six completed jobs from that group of inquiries. Source cost is $500 per completed job. At three completed jobs, it is $1,000. Those assumed results are not a forecast or a promised quantity.
Add the office and estimating expense. Do not calculate effective CPL by dividing the fee by a hoped-for weekly volume. Use actual delivery, then continue following the group through completed work.
Each lead goes to one buyer through theBuildd, but the homeowner can seek other quotes independently. Bad leads are replaced rather than refunded under the agreed terms. Exclusivity and a flat invoice do not guarantee profitability.
Audit one source with a useful reporting window
Record spend, charges, credits, delivered inquiries, reached homeowners, scope fit, bookings, attended assessments and completed jobs. Preserve the original source when a lead turns into a proposal or invoice.
Evaluate process problems early, but allow later decisions from the same group to be recorded. Do not divide this month’s spend by all jobs completed this month if some of those jobs came from earlier lead purchases. Separate acquisition groups and show their outcomes to date.
Compare your HVAC scope and territory with theBuildd. Bring the work you accept, staffed hours and actual acquisition ceiling. Put the complete offer beside your existing source, then judge the result using the same definitions.
