Furnace replacement leads are homeowner inquiries about replacing a furnace. Before buying, ask whether the provider distinguishes that request from an urgent no-heat call, boiler work or a discussion about switching systems. The name of the HVAC category is not enough to establish the project your estimator will find.
A homeowner can report that a furnace is old or unreliable without knowing whether replacement is appropriate. The technician’s assessment determines the recommendation; the lead records the request.
Disclosure: theBuildd supplies exclusive residential HVAC opt-ins. Furnace-specific coverage and filtering must be confirmed for your territory before purchase.
Start with the equipment the homeowner reports
Ask what heats the home and whether the person is requesting a replacement quote or help with a current problem. Record uncertainty instead of choosing a system type for them.
| Homeowner description | Intake question | Appropriate next step to discuss |
|---|---|---|
| “I want a new furnace” | What system and fuel do you have, if known? | Replacement assessment |
| “The house has no heat” | Are you asking for service today? | Availability check for a service assessment |
| “I want to change from gas” | Are you considering a furnace or another heating system? | Equipment-options conversation |
| “The boiler needs replacing” | Is the system actually a boiler? | Route to a company accepting boiler work |
| “The furnace is old but running” | Are you planning a replacement or gathering information? | Planned consultation with a clear next step |
This is a recommended contractor intake table, not a claim that every field is included with a lead. A caller should not diagnose equipment, declare it unsafe or advise the homeowner on repairs through a lead screen.
If the request is specifically about a heat pump, the heat pump lead guide belongs in the conversation. Keep that equipment choice separate from a furnace-only buying agreement.
Buy a territory your heating team can serve
Confirm service ZIPs, accepted systems and available assessment slots. A wide territory can produce calls your crew cannot reach promptly, especially when several urgent requests arrive together. Use actual travel and staff capacity when deciding what to accept.
Ask how the provider handles inquiries outside your fuel or equipment scope. If that distinction is not collected before delivery, decide whether your office can qualify it economically. Do not assume a precise furnace filter from a broad heating label.
The HVAC lead service explains the broader offer. It remains the owner for general heating and cooling purchases; this guide narrows the buying questions to furnace replacement.
Match the handoff to planned and urgent work
A planned replacement can begin with a scope call and a scheduled assessment. A no-heat request requires your office to establish whether timely service is available. Neither should be treated as a guaranteed replacement sale.
For a live transfer, someone must be ready to answer. For a booked appointment, agree the kinds of slots your team can accept and how scheduling changes are handled. For an opt-in, assign the first call and follow-up to a named person.
Ask what happens when the homeowner is unreachable or declines the next step. A replacement request can be real without producing an appointment, and a booked assessment can still lead to a repair recommendation.
Compare cost per assessed project and completed replacement
Track the homeowner’s stated request, contact result, assessed equipment, recommendation, proposal and completed work. This distinguishes a purchasing mismatch from a normal diagnostic outcome.
If a group of inquiries costs $1,000 and produces five attended replacement assessments, source cost is $200 per assessment. If two replacements are completed, it is $500 per completed replacement before office and selling expense. These are hypothetical counts and costs, not a benchmark or theBuildd result.
A source that also produces repair work should have that outcome recorded separately. Do not discard the repair revenue, but do not label it a replacement win to improve the report. The HVAC lead cost guide shows how to compare the same billing and outcome definitions.
What theBuildd’s general HVAC plan covers
Published pricing, checked 23 September 2026, lists a $300 trial for 4–7 opt-ins, an $800 weekly plan and monthly lead plans starting at $3,000. Your team qualifies base-plan inquiries. Optional monthly dispatching starts at $500 extra on the base tier and uses a live transfer or booked appointment handoff. Trial and weekly plans exclude it.
Confirm furnace scope and local availability before using those prices in a furnace-only budget. They do not guarantee a quantity of replacements or a steady heating-season volume. Demand depends on the territory, trade and local conditions.
Each lead is sold to one contractor through theBuildd. Homeowners can still request other quotes independently. Bad leads are replaced rather than refunded under the agreed terms; an inspection finding that repair is appropriate does not automatically establish a bad-lead claim.
Set the heating-season test before purchasing
Bring your accepted equipment, service ZIPs, assessment capacity and follow-up plan. Separate planned replacements from urgent service in the purchase discussion and your reporting.
Check furnace project fit with theBuildd. Agree the available scope and handoff, then evaluate the source on the work your team actually assessed and completed. If you also buy cooling work, use the AC replacement lead checklist for that separate project mix.
From opt-in to qualified lead
Start from the right definition. A furnace replacement enquiry is permission to have a conversation, and that permission is the thing you are buying. You have a qualified lead only once somebody has actually had the conversation and checked it against your criteria.
For this work, a reached homeowner has to confirm:
- fuel type and the reported symptom, as the homeowner describes it
- whether the homeowner wants replacement or a diagnostic first
- heating emergency or planned work, which routes differently
- access to the equipment and a decision maker for the estimate
Who makes that call is a purchasing decision, not a detail. Base plans leave it with your team. Optional monthly dispatching puts our callers on it, qualifying reached homeowners against your agreed criteria before handing over by live transfer or booked appointment. The opt-in goes to one buyer either way, and neither option guarantees contact, qualification or a job. See what counts as a qualified lead for the stage-by-stage version.
