Air conditioning gets replaced when it dies in a heatwave. That is not a figure of speech: across five years of residential permits, cooling replacements peak in July at 182,383 a month and bottom out in February at 110,433. The homeowner who makes that July call is not choosing a contractor; they are taking whoever answers. The whole purpose of an HVAC cold call is to have met that homeowner in February.
So this script is not one call. It is three, keyed to the calendar, because what a setter can honestly say to a homeowner changes with the season — and the offer that books is different in March, in August and in October. The skeleton underneath all three is the same as any setter call: a specific opener, a permission line, a short qualifying pass, and a close that is a time rather than a sale. Our solar cold call script lays that skeleton out; this page assumes it and fills in the HVAC lines. It is written for setters on a floor whose output is a held technician visit, not for field reps at a door — that motion is in door knocking for HVAC.
Disclosure: Scout Data is our product, and the permit date every opener below leans on — the last mechanical or HVAC permit recorded on a home — is what our files put beside the phone number. The lines work with the date from any source; without a date, they are a generic pitch and should be rewritten.
Seasonality and interval figures on this page come from our HVAC replacement statistics (derived August 30, 2026, from residential building permits). Permit coverage is not universal, so those figures are floors. The compliance lines are operational practice, not legal advice — have your script reviewed by counsel before it runs.
Where the three calls differ
| Pre-season call | After-the-heatwave call | Furnace call | |
|---|---|---|---|
| When | February–April (cooling); September (heating) | The two to four weeks after a heatwave or hard freeze | October–November |
| Anchor | Permit age on this home | What the whole neighbourhood just lived through | Permit age plus heating fuel |
| What is booked | A pre-season tune-up or assessment | A check on a system that struggled | A heating check, or a heat-pump conversation on electric homes |
| Homeowner’s state | Not thinking about it | Thinking about it, and annoyed | Planning, more often than panicking |
The furnace column is the one setters underrate. Heating permits barely swing across the year — a 22% range against cooling’s 65% — and their peak lands in October through January, before the deepest cold. That is the signature of a purchase made on a plan rather than in an emergency, and a planned purchase is one a setter can get in front of.
Call one: the pre-season call
The homeowner has not thought about the air conditioner since September. The opener has to give them a reason to, and the only honest reason is specific to their house.
“Hi, is this [first name]? [Name] with [company] — I’m calling about your place on [street]. From the permit record, the last cooling work we can see on the house was in [year]. Does that sound about right, or has it been replaced since?”
Ask the question and wait. About a quarter of homes in our permit data replace cooling inside seven years and a quarter wait seventeen or more, so the record is a starting point and the homeowner is the authority. “No, we did it two years ago” ends the call politely and fixes the file. “That sounds right” confirms the one fact the rest of the call needs.
Then the permission line and the offer:
“I’m not selling you a system on this call — a unit that age is usually fine, it’s just at the point where it’s worth having someone look before the summer rather than in it. We’re booking pre-season checks in [neighbourhood] in the next couple of weeks. It’s [price or ‘no charge’], takes under an hour, and you get a straight answer on what shape it’s in. Would a weekday or a Saturday suit?”
Two qualifying questions belong in this call and no more. First, ownership — “and it’s your place, not a rental?” — because a tenant does not replace a condenser. Second, “anything you noticed last summer — not keeping up on the hot days, running all the time, a bill that jumped?” A yes moves the appointment’s tone from routine to diagnostic, and the technician should know that before the truck leaves.
Call two: the after-the-heatwave call
This call has an anchor the pre-season call lacks: a shared event. Everyone on the street ran their system flat out for a week, some of those systems did not keep up, and the homeowners who limped through are receptive for a few weeks afterwards. Almost nobody calls them.
“Hi, is this [first name]? [Name] with [company]. We’ve been out on [street] all week after that heat — a few systems in [neighbourhood] didn’t keep up. Yours is on the older side from what we can see in the permit record. How did it do?”
“How did it do?” is the whole opener. It asks about their week, not your product, and it gets a real answer — “fine,” “it struggled,” or “it died on Tuesday and we already replaced it.” Each of those is a different call:
- “Fine.” “Glad to hear it. It’ll be an old unit by next summer though — would a check in the spring be worth putting in the diary?” Log a callback for the pre-season window and let it go.
- “It struggled.” The book. “That’s usually the year before it goes. We can have someone look this week while it’s fresh — it might be a refrigerant issue, might be the unit, but you’d rather know in August than in the next heatwave. Thursday or Saturday?”
- “Already replaced it.” Thank them, ask who did it, log the correction. This homeowner is off the replacement list for a decade and on a maintenance list from now.
This call is time-limited in a way the others are not. The window after a weather event closes as memory fades, and a file worked three weeks late is a pre-season call in disguise. The same logic runs the winter version after a hard freeze — the words change to “kept up” and “furnace,” and the offer to a heating check.
Call three: the furnace call
October is when heating gets replaced on purpose. The setter’s anchor is the permit date again, and on homes that heat with electricity there is a second fact worth putting in the opener.
“Hi, is this [first name]? [Name] with [company], about your place on [street]. Before the cold sets in we’re doing heating checks in [neighbourhood] — the last heating work on record for your house is from [year], so it’s on our list. Has it been done since?”
For an electric-heat home, one added sentence: “And since the house is electric, if it ever does need replacing, a heat pump is the like-for-like — the technician can tell you whether that’s worth a look.” That is the heat-pump conversation in full on a cold call. Whether it is a good idea for this house depends on the house, and the technician decides that. The share of replacements that name a heat pump runs from 35.6% in Maryland to 1.0% in Michigan in our permit data, and the ordering tracks what the home already burns far more than climate — so the sentence belongs on the electric-heat file and nowhere else.
The close is the same alternative-choice time as every other call, with one honest reason for the timing: heating checks booked in October happen in October; the ones requested in the first cold snap of December compete with every emergency in the county.
Lines the script leaves out
- “Your system is about to fail.” Nobody knows that. Medians are floors, quartiles are wide, and a fifteen-year-old unit in a mild climate with a good service history may have years left.
- A replacement price, or a monthly payment. Nobody has sized the house or seen the ductwork.
- A rebate amount, a tax credit, or a utility programme by name. These change, vary by state and utility, and attach to equipment nobody has specified. “There may be programmes worth asking about” is the ceiling.
- Any suggestion the call is from or on behalf of the utility or a government programme. It is not, and saying otherwise is the kind of claim regulators act on.
- A deadline that does not exist. The season is a real reason to book now. An invented one is a cancellation.
- Anything after “take me off your list,” beyond confirming it is done and doing it the same day.
Which homes get which call
The file decides most of this before the setter dials. A pre-season list is the homes whose last cooling permit is past the local threshold — the national median gap between cooling permits on the same home is 12 years, and 13 for furnaces, both floors. The after-event list is the same homes, filtered to the streets the weather actually hit. The furnace list adds heating fuel, so the heat-pump sentence lands only where it is true. Which homeowners are on any of those lists, and when each list gets worked, is a planning problem more than a script problem — HVAC replacement season planning lays the year out month by month, and how to get HVAC leads covers the signals the file is built from.
Every one of those files goes through a do-not-call scrub and a line-type check before it reaches a dialer, and the setter’s disposition codes carry “renter,” “already replaced” and “wrong number” as separate outcomes so the file can be judged apart from the lines. Measure the script on held technician visits per right-party conversation, by season — a February script and an August script are not competing on the same homeowner.
Frequently asked questions
What should an HVAC cold call actually try to book?
A technician visit with a small, honest purpose — a pre-season tune-up, an assessment of an aging system, a second opinion on a quote. Not a replacement. Nobody buys a furnace on a cold call, and a setter who tries to sell one is competing with the homeowner’s instinct to wait until it breaks. A technician in the house, in front of a fifteen-year- old unit, has the replacement conversation for you.
Can a setter tell a homeowner how old their HVAC system is?
Only what the record shows, said as what it is: “the last mechanical permit we can see on your place is from [year].” That is a fact about the last permitted work, not the age of the equipment — a system replaced without a permit will not appear, and some jurisdictions do not publish at all. Say the permit date, ask whether it is right, and let the homeowner correct the file.
When is the best time of year to cold call for HVAC?
Before the season that breaks the system, not during it. Residential cooling permits peak in July and bottom out in February, a 65% swing in our permit data; heating peaks in a broad October-to-January plateau. A February call reaches a homeowner while a planned replacement is still cheaper than an emergency one. A July call reaches a homeowner who is already on the phone with whoever answered first.
Should the script mention heat pumps or rebates?
Heat pumps, yes, where the house heats with electricity — it is the like-for-like replacement there, and the setter can say so. Rebates and tax credits, no. Incentive programmes change, vary by utility and state, and depend on equipment nobody has specified yet. “There may be programmes worth looking at, and the technician can walk you through what applies” is the whole of what a setter should say.
