The Unsold Estimate: A Five-Step Follow-Up System for HVAC Replacement Quotes
Repair calls close themselves; five-figure replacement quotes sit in the CRM with no owner and no deadline. A five-step follow-up system for the unsold estimates you have already paid to generate.
by Jerrod Anthraper
Your tech spends ninety minutes at a house on a no-cool call, gets the eighteen-year-old condenser limping again, and leaves a written quote on the kitchen counter for a full system replacement. Eleven thousand four hundred dollars. The homeowner says what homeowners say: "Let me talk to my wife."
That quote goes into the CRM. Your tech has eight calls tomorrow. Nobody calls the homeowner back. Thirteen days later, a competitor's truck is in that driveway for two days, and you find out because your tech drives past it on the way to another job.
The leak: the pile of quotes nobody owns
Every HVAC company has two sales processes running at once, and only one of them is actually staffed.
The repair call runs itself. The customer is uncomfortable, they chase you, urgency does the selling, and your dispatcher closes it by picking up the phone. That process works because the customer supplies the pressure.
The replacement quote has no such engine. It's four to fifteen times the ticket size, and it's the one you leave to chance. The quote gets emailed or left on a counter, and then it sits — because the homeowner's system still sort of works, and "let me talk to my wife" is a real sentence, not a brush-off.
Meanwhile they're getting two more quotes. About 78% of sales go to whoever responds first, and in replacement work "first" doesn't mean first to quote. It means first to follow up while the decision is still open.
Why it happens in shops that are otherwise well run
The root cause isn't laziness and it isn't a bad CRM. It's that the person holding the quote is a technician.
Your best tech is a diagnostic and installation professional with a route to run. Follow-up is somebody else's competency and, more to the point, somebody else's time. When it's assigned to him anyway, it gets done for the quotes he personally feels good about and skipped for the rest — which is a filter based on his read of the room, not on deal value.
The second cause is that nothing in your operation creates a deadline. A repair has a deadline built in by physics. A replacement quote has no expiration, no next step, and no calendar entry, so it competes for attention against jobs that do. It loses that fight every time, and it loses it silently.
The third cause is that unsold estimates are rarely reported on. Most shops track revenue and close rate on completed jobs. Very few can tell you, right now, the dollar value of quotes issued in the last thirty days with no disposition. That number is usually large enough to change how the owner spends Monday morning.
The five-step unsold estimate system
None of this requires new software or a new hire to start. Steps one and two you can do this week with what's already in your system.
1. Split the two pipelines and put a dollar value on the quiet one.
Pull every replacement or install quote issued in the last ninety days that has no won or lost disposition. Total the dollar value. Sort by age. This is now a real pipeline with a real number attached, not a pile, and it gets reviewed in the same meeting where you review revenue.
While you're in there, count how many of those quotes received zero follow-up contact after delivery. In most shops it's the majority, and seeing the two figures next to each other is what makes the rest of this stick.
2. Start the clock at quote delivery, not at "when I get to it."
Define the follow-up window from the moment the customer receives the number. The first touch goes out the same day, within a few hours, while the tech's visit is still the freshest thing that happened in that house.
This single change does more than any script. A same-day touch lands while the homeowner is still telling their spouse about the tech who explained the failing capacitor. A touch on day six lands cold, after two competitors have already been through.
3. Build a three-touch ladder with three different jobs.
Repeating "just following up on that quote" three times is not a system. Each touch needs its own purpose.
Touch one, same day: confirm they received it and ask what question they'd want answered before deciding. That's a genuine question, and the answers are useful — they're usually about financing or about whether the old unit can last another season.
Touch two, day three or four: answer the specific thing they raised, in writing, with the number attached. Financing terms, efficiency savings on the specific model quoted, warranty details. Not a nudge — new information.
Touch three, day ten to fourteen: a direct, low-pressure decision question. Are they moving forward, holding until spring, or did they go another direction? All three answers are useful, and you learn something whichever way it goes.
4. Answer the objection you already know is coming.
You've heard it a thousand times: it's a lot of money and they weren't planning to spend it this month. Handle it in the quote itself rather than waiting for it to surface.
Quote good, better, and best with monthly financing shown next to each. Include the estimated repair cost of keeping the current system for another twelve months, because "do nothing" is the real competitor, not the shop down the road. Make the do-nothing option carry a visible price.
5. Force a disposition and close the loop either way.
Every quote gets marked won, lost, or scheduled for a specific future date. No quote stays open indefinitely.
A "lost" quote with a reason attached is worth far more than an open one, because it tells you whether you're losing on price, timing, or speed — and those have completely different fixes. A quote marked "revisit in April" becomes a scheduled task instead of a forgotten line item, which is how you fill the shoulder season.
The proof: what follow-up discipline actually moves
Here's a case study from outside HVAC that maps closely, because the shape of the sale is the same — phone-driven, quote-based, and won or lost on who stays in the conversation.
AMG Transport Co., a transportation and logistics company, went from a 32% close rate to 46% in two months after putting a system like this in place, and their review volume went from 5–6 per month to 5–6 per day.
Fourteen points of close rate on quotes you were already issuing, from prospects you'd already paid to acquire and already sent a truck to. No additional marketing spend, no additional leads. That's what the unsold estimate pile is worth when someone finally works it.
Where this gets automated
The judgment stays with you. Which systems to quote, how to price, what good-better-best looks like in your market — none of that is automatable, and you shouldn't want it to be.
What can run without a person is the ladder itself. Our AI agent, James, sends the same-day touch, captures the homeowner's actual question, delivers the financing or efficiency answer on day three, asks the decision question on day twelve, and pushes a disposition into your CRM either way. He also picks up the reply that comes back at 9 p.m., which is when homeowners tend to make these decisions.
If you want to size the opportunity before talking to anyone, run step one this week. Total your open unsold estimates from the last ninety days and multiply by ten percentage points of close rate. That number is what your follow-up gap is costing you per quarter, and it's usually the most expensive thing in the building that nobody has a name for.
