Every aged lead has an age. An aged HVAC lead also has a season, and the season is the more useful field. A homeowner who filled in a heating-and-cooling form in the second week of July was, with very high probability, standing in a hot house with a dead compressor; the same form filed in March was somebody planning ahead. Ninety days later the two records are the same age and priced the same, and one of them is a finished job while the other may still be a decision nobody has made. This page is about telling them apart before the batch reaches the floor, and about what an aged HVAC row costs, carries, and can be dialed with.
The economics of aged versus fresh — why the discount is real, when idle dialer capacity makes it close to free, why cost per lead is the wrong number — are the same in every vertical and are laid out once in aged solar leads. They are not repeated here. What is different about HVAC is the calendar, and the calendar is where a heating-and-cooling floor either makes an aged batch pay or wastes it.
Disclosure: Scout Data sells homeowner data and leads to HVAC call centers, including files built on the age of the equipment rather than on an inquiry, and the permit calendar below is from our own database. The read is the one we would give a floor manager deciding whether to buy the batch.
The inquiry month is the first field to read
Residential HVAC permits have two seasons, and they are not the same shape. Cooling permits swing 65% from a February floor of 110,433 to a July peak of 182,383 across 2021–2025 — a spike, because air conditioning gets replaced when it dies in a heatwave. Heating permits swing only 22%, and their peak is a broad October-to-January plateau, because furnaces are replaced on a schedule before the cold. The full month-by-month table and the method behind it are in HVAC replacement statistics. Laid over an aged file, that calendar says what each row most likely was:
| Inquiry filed | What the permits say was happening | What the form most likely was | What is left when it is “aged” |
|---|---|---|---|
| February – May | Cooling permits at their floor (110,433 in February) | A planned cooling replacement, or a spring tune-up | Mostly still open: the homeowner was ahead of the season and nothing forced the decision |
| June – August | Cooling permits at their peak (182,383 in July) | A breakdown in a heatwave — repair or emergency replacement | Usually resolved within days; what survives is a homeowner who patched the unit and is one summer closer to replacing it |
| September – October | Heating permits climbing into an October–January plateau (117,100 in October) | A planned furnace replacement before the cold | Open through the plateau; the schedule is being made and a second contractor is still welcome |
| November – January | Heating permits on the plateau (117,345 in December) | A furnace that failed, or a bill that arrived | Repairs are done; replacements filed on a bill are the durable rows, and they re-open on the next bill |
The last column is a reading of the calendar, not a measured decay curve — we do not run the dialers that would produce one. But the direction is not in doubt. A distressed purchase resolves in days because the house is uninhabitable until it does; a planned purchase resolves when the homeowner decides, which can be months, and an aged file mixes the two at one price. Sort the batch by inquiry month before anyone dials it, and the peak-month rows — July cooling, December heating — go to the back of the queue or into a separate test.
What the row costs, and what it carries
One vendor prints its tiers, which is useful for the shape even if you buy elsewhere. As publicly advertised on 20 September 2026, Aged Lead Store’s HVAC page says buyers can “shop by location, job type (repair, install, tune-up, upgrade), system (AC, furnace, heat pump), and lead age,” puts the category at “80–95% discounts compared to exclusive ‘hot’ leads,” and routes pricing to its home-improvement grid:
| Lead age | 1–249 | 250–999 | 1,000–4,999 | 5,000–9,999 | 10,000–24,999 | 25,000+ |
|---|---|---|---|---|---|---|
| 30–90 days old | $2.00 | $1.50 | $1.25 | $1.00 | $0.85 | $0.70 |
| 91–365 days old | $0.75 | $0.60 | $0.50 | $0.40 | $0.30 | $0.25 |
Pricing on this page is as publicly advertised at the time of writing — confirm current pricing with each vendor, and with our sales team for Scout Data. Discounts move with age, volume and season.
Two lines on the same vendor’s pages deserve a closer read than the price. The first is that the three filters — job type, system, age — are exactly the three fields worth insisting on from any seller, because an HVAC batch without them cannot be sorted by the calendar above. A “repair” row filed in July is a different product from an “install” row filed in March, and a seller who cannot split them is selling you the average. The second is the homeowner check: the page says “renters are removed” on a regular cycle and, in the same breath, that “the store does not yet show which individual leads have been checked.” Read that as a file-level claim, and count renters as their own disposition on the first pass.
Repair, replace, tune-up: three requests at one price
The job-type field is where the money is, so it is worth being precise about what each value is worth once it has aged. A repair request is the shortest-lived row in any home-services vertical: the homeowner hired whoever answered, or the unit was patched, and either way the inquiry is over. Its residual value is the equipment — a repaired unit is an old unit that will be replaced on a later date, and that date is the next peak. A replacement or install request is the one an aged file is good at, because the homeowner had already decided the unit was at the end of its life and nothing about a delay changes that. A tune-up request is neither; it is a maintenance-plan customer, cheap to book and worth little per visit, but it is the row most likely to still pick up the phone.
The permit record puts a number on why replacement rows keep. Where the same home shows two cooling permits, the median gap between them is 12 years; for furnaces it is 13, with the 75th percentile at 17 and 19. Both medians are floors, because a jurisdiction that began publishing in 2005 cannot show a 25-year interval. A homeowner who asked for a replacement quote on a unit past that mark still has a unit past that mark six months later — the request aged, the equipment did not get younger.
Dial the batch against the next peak, not the last one
This is the move that has no equivalent in roofing or solar. An aged cooling batch bought in October is a batch of homeowners whose units survived one more summer. Dialed in October it is a poor list: the emergency is over, the heatwave is over, and the furnace is the appliance on their mind. Held and dialed in February through May it becomes the list an HVAC floor most wants — homes with a known-old cooling system, reached before the season that will kill it, while the homeowner can still plan the purchase rather than take whatever truck is free in July. The same logic runs the other way for furnace rows: filed in January, dialed in August and September, ahead of the plateau.
Before it goes to the floor, run the permit check. Match the batch to the address and look for a mechanical permit dated after the inquiry; 1,255,564 residential HVAC permits were filed in the twelve months to August 2026 in our permit database, and each one on an aged file is a job that went to someone else. Suppress those rows. Then read the check for what it is — a like-for-like change-out goes unpermitted in many jurisdictions, so a clean row is not proof of an open decision, and the setter still asks in the first ten seconds. A permit dated well before the inquiry is informative too: a system installed three years ago that generated a quote request was a repair or a warranty call, and the row belongs with the repairs.
What the batch cannot tell you is house age, and it does not need to. The median home is 39 years old when an HVAC permit is pulled on it and has already cycled through several systems; build year says nothing about the unit except in the 15-to-24-year band, where the original equipment is reaching the end of its first life. The permit that matters is the last mechanical one, and an aged row gives you the homeowner’s own report of it instead.
Manual dial, inside the window
The consent an internet lead came with was given to the sites named on the form, weeks ago, and it does not travel to you with the CSV. The vendor quoted above is explicit about the consequence: its shared internet leads are sold “for use in email, direct mail, door knocking, or manual dialing not using regulated technologies to phones not on any DNC lists.” Read that as the category’s own description of what an aged lead is licensed for. Re-scrub every batch inside the 31-day window, run your internal suppression file over it, and keep the aged rows out of any campaign the dialer places on its own. The HVAC-specific routine — including the state rules that only exist after a declared disaster, which a heatwave can be — is in DNC scrubbing for roofing and HVAC. None of this is legal advice; your configuration belongs with counsel.
Measure it in technician visits, by season
An HVAC lead converts to a held technician visit first — someone in the house with a gauge set — and to an install only after that. So the number to fix before buying is cost per held visit, with your own visit-to-install rate behind it, and the arithmetic for working back from there to what a row can be worth is in how to price a bought lead. Then stamp the batch by inquiry month and job type at import, and judge each slice separately. A February-filed replacement slice that holds visits and a July-filed repair slice that holds none is not a verdict on aged HVAC leads; it is a filter for the next order, and the vendor’s own selects can apply it.
There is a second way to build the same list, and it starts from the county rather than the form. Every home whose last cooling permit is past the local median, dialed in spring; every home whose last heating permit is past its median, with the heating fuel on the row, dialed in late summer; every arms-length sale in the last ninety days, dialed the week it records. Nobody filled anything in, so there is no inquiry to age and no prior buyer who dialed it last month. The three lists, what each row carries, and what to suppress before load are in HVAC call center leads. An aged batch fills idle hours cheaply; a permit-built list fills them with equipment that is actually old. Run both in the same pre-season window if the capacity is there, and read the visits-per-thousand-dials line side by side.
Permit-calendar, interval and permit-volume figures are from our own permit database, derived August 30, 2026, and are floors — a home only enters the interval sample if the same equipment was permitted twice inside a jurisdiction’s coverage window.
Frequently asked questions
What is an aged HVAC lead?
A homeowner who asked for a heating or cooling quote through a web form some weeks or months ago. The request was sold to several contractors in real time; once they stopped calling it, the record is resold at a discount as “aged.” The row carries the form — name, address, a phone, the date, and often the system type and whether it was a repair, install or tune-up. It does not carry whether the work has since been done, and on an HVAC lead the month it was filed says more about that than the number of days since.
How much do aged HVAC leads cost?
One vendor prints it. As publicly advertised on 20 September 2026, Aged Lead Store’s HVAC page routes to its home-improvement category, where leads 30–90 days old run from $2.00 each for a handful down to $0.70 at 25,000 or more, and leads 91–365 days old run from $0.75 down to $0.25. The page puts the whole category at “80–95% discounts compared to exclusive ‘hot’ leads.” Treat that as the shape of the market rather than a quote, and price the batch on technician visits held, not on rows bought.
Are aged HVAC leads worth buying out of season?
Only if you read the inquiry month first. A cooling inquiry filed in a July heatwave and resold in October is almost always a job that was done or a unit that was patched; a cooling inquiry filed in March is a planned purchase that may still be open. The batch you want out of season is the one whose rows were filed before the last peak, dialed again before the next one — a homeowner who did not replace the unit last summer is a homeowner with a unit one summer older.
How do I know whether an aged HVAC lead already replaced the system?
Look for a mechanical permit at the address dated after the inquiry. 1,255,564 residential HVAC permits were filed in the twelve months to August 2026 in our permit database, and every one on an aged file is a homeowner who is no longer a lead. A like-for-like change-out goes unpermitted in many jurisdictions, so treat the check as a suppression pass rather than proof the remaining rows are open, and have the setter ask in the first ten seconds.
