HVAC Estimate Follow-Up: How to Close the Quotes You Already Paid For
Most unsold replacement quotes are not lost - they are undecided, and nobody calls back. The follow-up system that turns them into installs: what to set up at the kitchen table, the sequence after you leave, what to say instead of "just checking in", and how to measure it.

Every unsold estimate in your system cost you money to create. You paid for the lead, the call, the drive, and an hour or two of your comfort advisor's time at the kitchen table. Then the homeowner said they needed to think about it, and in most shops that was the last conversation anyone had with them.
That is the most expensive habit in residential HVAC sales, because most of those customers are not saying no. They are waiting on a spouse, a financing answer, a second quote, a tax refund, or for the old system to finally quit. Somebody is going to install their new system. The question is whether it is the company that already measured the house and wrote the quote, or the one that called back.
This guide covers how to measure what your unsold estimates are worth, what to set up before you leave the house, a follow-up sequence that runs for a year without becoming a nuisance, what to say on each touch, the discount rules that keep follow-up from training customers to wait, and the software that makes it run without depending on anyone's memory. The numbers are examples; run your own.
Key takeaways
- →Unsold estimates are the cheapest revenue you have, because the lead cost is already spent. A shop running 60 replacement quotes a month at $9,000 that moves its close rate from 30 to 40 percent sells 6 more systems - about $54,000 of revenue and roughly $24,000 of gross profit a month at a 45 percent margin.
- →Measure before you fix: close rate by comfort advisor and by lead source, how many quotes are open, how many days customers take to decide, and a required reason on every lost quote. Without a lost reason, every lost sale looks like "price".
- →Set the follow-up at the table. Agree on when the customer will decide and when you will call, leave good, better and best options in writing, prequalify financing before you leave, and send the proposal electronically the same day.
- →Run a written sequence: same-day recap, a call from the advisor within two days, then touches at day 7, 14 and 30, then monthly or seasonal contact for 12 months. The advisor owns the first two weeks; after that, the office and automation take over.
- →Every touch should give the customer something - an answer, a financing option, a rebate deadline, a scheduling window - not "just checking in". Find the real objection, because "we need to think about it" is almost never the real one.
- →Never invent a discount on the follow-up call. Discounts that appear only after a customer waits teach customers to wait. If you offer one, make it a written policy with a real reason and a real deadline.
- →Declined repair estimates are a second pile worth working: a $600 to $1,500 repair the customer put off is often a replacement lead six months later.
Why unsold estimates are the cheapest revenue you have
Start with what an estimate costs. Whatever you spend on marketing per in-home appointment - pay-per-click, lead services, the share of your advertising that produces replacement calls - is already gone by the time the advisor knocks. Add the advisor's time, usually two to three hours including the drive, and the load calculation, photos and equipment selection behind the quote.
Now count the pile. A shop running 60 replacement quotes a month at a 30 percent close rate sells 18 systems and leaves 42 quotes unsold every month - roughly 500 a year. If marketing cost $300 per in-home appointment, as an example, that is $12,600 a month of lead spend sitting in a list that nobody calls.
The upside is large because the hard part is done. Moving close rate from 30 to 40 percent on those 60 quotes sells 6 more systems a month. At $9,000 a system and a 45 percent gross margin, that is about $54,000 of revenue and $24,000 of gross profit a month - with no new marketing, no new trucks and no new hires. The small residential software guide on this site uses the same math to make the case that follow-up is one of the first jobs an owner should take off the truck for.
And the pile keeps paying after the first month. If 5 percent of a year's 500 unsold quotes close somewhere in the following 12 months because you stayed in touch, that is 25 systems - about $225,000 of revenue from customers who would otherwise have bought from whoever called them last.
Measure your close rate honestly
Most shops know their close rate roughly, as one blended number. That number hides almost everything useful. Break it down before you change anything.
By comfort advisor. Close rates commonly differ widely between advisors in the same company on the same kind of leads. A big spread is a training and process opportunity, not just a talent difference - and it tells you whose follow-up habits to copy.
By lead source. A customer whose system died yesterday and called you off a maintenance visit closes very differently from a pay-per-click lead collecting three quotes for a system that still runs. If you compare advisors without separating lead sources, you are mostly comparing who got the better leads.
Open quotes and days to decision. Count how many quotes are open right now, and how many days the closed ones took from presentation to signature. If most of your sales close the same day or within a week, your follow-up window is short and intense. If a meaningful share close after two or three weeks, a shop that stops calling after the first week is giving those sales away.
Lost reasons. Make a lost reason a required field when a quote is marked lost: bought from a competitor (and which one, if known), price, financing denied, decided to repair, system still running / not now, could not reach. Without it, every lost quote gets filed as "price", and you will keep cutting margin to fix a problem that is often timing or trust.
Why customers do not decide at the table
"We need to think about it" is a polite way of ending the conversation. Behind it is usually one of a short list of real reasons, and each one needs a different follow-up.
The other decision-maker was not there. One spouse sat through the presentation; the other will see a number on a piece of paper. The fix is upstream - the CSR asks at booking whether everyone involved in the decision can be there - and in the follow-up, offering a short call or video walkthrough with both of them.
Money or financing. The customer does not know whether they can afford the monthly payment, or was afraid to ask. Prequalifying with a soft credit pull at the table and showing a monthly payment on every option takes this off the list. The financing guide on this site covers how to build the dealer fee into the price.
They are collecting quotes. The customer has two more appointments this week. You will not stop that, but you can be the quote that is easiest to understand, the only one that measured the house, and the company that called back with answers.
The system still runs. For repair-or-replace customers whose equipment still works, the honest answer is often "not yet", and the follow-up should respect that. These customers belong in a long, low-pressure sequence - and when the system fails in the first heat wave, you want to be the number they already have.
Sticker shock or trust. Some customers were surprised by the price or not convinced by the presentation. A follow-up that only repeats the price will not fix that; one that answers their questions, shows the load calculation, or offers a different option might.
Set up the follow-up before you leave the house
The best follow-up starts at the kitchen table. An advisor who leaves with "I'll be in touch" is starting from nothing. One who leaves with an agreed next step is continuing a conversation.
Agree on a decision date. Ask when they expect to decide and whether you can call them that day. "When do you think you'll have talked it over - Thursday? Is it OK if I call you Thursday evening?" Most customers say yes, and now the call is expected rather than a sales interruption.
Leave options in writing. Present good, better and best, and leave all three with the customer. A single take-it-or-leave-it number gives them nothing to think about except whether to call someone else. The pricing guide on this site covers building the tiers.
Prequalify financing before you go. If financing is part of the conversation, run the prequalification at the table and show the monthly payment for each option. A customer who knows they are approved for a payment they can afford has one fewer reason to wait.
Send the proposal the same day. An electronic proposal they can open, compare and sign on their phone - with photos of their current equipment and the options side by side - keeps your quote in front of them while they meet your competitors. Most field platforms and quoting tools can send one before the advisor reaches the next appointment.
Write down what you learned. The advisor's notes - who decides, the real objection, the timeline, what they cared about - are what make every later follow-up specific. If the notes live in the advisor's head, the office cannot follow up well when the advisor is busy or gone.
A follow-up sequence that runs for a year
Write the sequence down, put it in your software, and assign an owner for each step. The point is that every unsold quote gets the same treatment whether the advisor is having a great week or a terrible one.
Same day: a text and email with the proposal link, a short thank-you, and the answer to any question left open at the table. Day 1 or 2 (or the agreed decision date): a phone call from the advisor who ran the appointment. This is the most important touch in the sequence; its job is to find out where the customer stands and what is in the way.
Day 7: a second call or a personal text from the advisor, ideally with something new - a financing option, an answer to a question, an install date that is open next week. Day 14: a call or text from the advisor or the office, again with a specific reason to call. Day 30: a final direct touch: "We'll keep your quote on file - here's how to reach us when you're ready."
After 30 days, the quote moves from the advisor to the office and to automation. Monthly or seasonal contact for 12 months: a pre-season tune-up offer, a note when a rebate or financing promotion starts, a reminder before the first heat wave or cold snap. The database marketing guide on this site covers how to run these campaigns against your customer list without becoming spam.
Stop when they say stop, and close the loop when they buy elsewhere. Mark the quote lost with the reason, and keep the customer in your normal marketing - the company that installed their system will not always be the one they call for service.
Mind the rules for automated texts and calls. Federal and state rules on automated or marketing texts and calls apply to follow-up campaigns, and some states are stricter than federal law. Get consent to text at booking, include opt-out language, and check your state's requirements before switching on an automated sequence.
What to say on each touch
The worst follow-up is "just checking in to see if you had any questions." It gives the customer nothing, asks them to do the work, and is easy to ignore. Every touch should carry something the customer did not have before.
Lead with the open question. "You mentioned you wanted to see what the payment would be on the heat pump option - I ran it, it's $X a month." Or: "You asked whether the ductwork in the back bedroom could be fixed - I talked to our install manager and here's what we'd do." This is where the advisor's notes pay off.
Find the real objection. Ask directly and politely: "Where are you landing - is it the price, the timing, or something about the options?" Then deal with what they actually said. If it is price, offer a different option, not a discount on the same one. If it is timing, agree when to check back. If they bought elsewhere, thank them and ask what made the difference - that answer is worth more than the sale.
Make it easy to say yes. Have an install window to offer, a way to sign from the text, and the financing application ready. A customer who decides on the phone should be able to commit on the phone.
Do not argue with a competitor's quote you have not seen. If the customer has a lower price, ask what is included - equipment model and efficiency, a load calculation, permit, warranty registration, labor warranty, duct changes - and explain the differences on your own quote. Customers comparing quotes often cannot tell what they are comparing.
Discounts: make them a policy, not a reaction
The fastest way to wreck follow-up is to make it the place where prices drop. If a customer learns that waiting a week produced a $500 discount, they and everyone they tell will wait. And an advisor allowed to discount on the follow-up call will discount on every call.
If you use discounts, make them a written policy with a real reason and a real deadline: a manufacturer or utility promotion that actually ends, a slow-season install price for scheduling in the trough, a maintenance-plan member price. Then the follow-up is news - "the promotion we talked about ends on the 30th" - rather than a negotiation.
A $500 discount on a $9,000 job at a 45 percent margin cuts gross profit from $4,050 to $3,550 - about 12 percent of the profit on the job for a 6 percent price cut. Offering a lower tier, a different financing term, or a scheduling-based price usually closes the same customer without teaching them anything.
Track discounts by advisor. If one advisor's close rate looks great and their average gross margin is several points lower than everyone else's, the follow-up problem has been solved with your profit.
Do not forget declined repair estimates
Replacement quotes get attention because the tickets are big. The second pile is the repair estimates technicians write on service calls that customers decline - the capacitor that is failing, the coil that is leaking slowly, the $600 to $1,500 repair the customer decided to put off.
Work it the same way, on a shorter sequence. As an example, a shop running 600 service calls a month where 10 percent end with a declined repair estimate has 60 of them a month. Closing 20 percent of those within a few weeks is 12 repairs - at an $800 average, about $9,600 a month that was already diagnosed and quoted.
And many declined repairs are tomorrow's replacement. A customer who declined a $1,200 repair on a 15-year-old system is a replacement conversation waiting to happen. Flag those for the comfort advisor and add them to the long-term sequence, with the technician's photos and notes attached.
Make sure techs record the declined work in the field platform with a price, photos and a short reason. A recommendation that only exists as something the tech said out loud cannot be followed up on.
Software: make it run without anyone remembering
Follow-up fails when it depends on memory. The advisor has six appointments this week and a callback; the quote from last Tuesday is the thing that slips. The software job is to make the next step visible, assigned and automatic where it can be.
Your field platform is the starting point. ServiceTitan, Housecall Pro, Jobber and the other major platforms track estimates by status, send electronic proposals customers can sign, and can send automated reminders on open quotes. Set them up so every presented quote has a status, an owner and a next follow-up date, and so a quote cannot be marked lost without a reason.
Two-way texting matters because customers reply to texts they will not answer as calls. If your platform's texting is limited, a dedicated messaging tool like Podium can handle conversations and payment links. For website leads, online quoting tools such as DinoQuote let homeowners see a price range before booking, which filters some of the "just collecting quotes" visits before they happen.
AI tools increasingly help here: drafting a follow-up text from the advisor's notes, summarizing a recorded in-home appointment, flagging quotes that are about to go stale, or running the 12-month nurture sequence. Use them for the drafting and the reminders. Keep the day 1 or 2 call and the objection conversation with a person.
Whatever you use, run one report every week: quotes presented, quotes open by age, follow-ups due and overdue by advisor, and quotes lost by reason. The report is what makes the sequence happen.
A 30-day plan to fix estimate follow-up
Week 1: measure. Pull the last 6 to 12 months of replacement quotes. Calculate close rate by advisor and by lead source, days to decision for closed sales, and the number of open quotes. Add a required lost-reason field going forward.
Week 2: work the backlog. Sort open and recently lost quotes by age and value, and have advisors or the office call the last 90 days of them with something specific to offer. Pull declined repair estimates on older systems into the same list. Some of these will close this month.
Week 3: change the table habits. Decision date and permission to call, three options in writing, financing prequalified, proposal sent the same day, notes in the system. Write your discount policy and make it the only discount advisors can offer.
Week 4: build the sequence in your software, assign owners, turn on the automated touches, and start the weekly follow-up report. Track close rate, days to decision and average gross margin per sale every month; the margin number tells you whether you improved follow-up or just started discounting.

Frequently asked questions
Q.How do you follow up on an HVAC estimate?
Set up the follow-up before you leave: agree on when the customer will decide and that you can call that day, leave good, better and best options in writing, and send the proposal electronically the same day. Then run a written sequence - a call from the advisor within two days, touches at day 7, 14 and 30 with something specific each time, and monthly or seasonal contact for 12 months after that.
Q.What is a good close rate for HVAC replacement estimates?
It depends heavily on lead source - a customer whose system just failed closes very differently from an online lead collecting three quotes - so compare close rates by lead source and by advisor rather than against one industry number. What matters is the change: on 60 quotes a month at $9,000, moving from 30 to 40 percent sells 6 more systems, about $54,000 of revenue and $24,000 of gross profit at a 45 percent margin.
Q.How long should you follow up on an unsold HVAC quote?
About a year. Most decisions happen within the first few weeks, so the comfort advisor should own the first 14 to 30 days with direct calls and texts. After that, move the quote to the office and automated campaigns with monthly or seasonal contact - many repair-or-replace customers buy when their system finally fails, and you want to be the company they already have a quote from.
Q.Should HVAC contractors offer a discount on follow-up?
Not as a reaction to a customer waiting. Discounts that appear only on the follow-up call teach customers to wait and cut margin fast: $500 off a $9,000 job at a 45 percent margin takes about 12 percent of the gross profit. If you discount, make it a written policy with a real reason and deadline, such as a manufacturer promotion or a slow-season install price, and offer a lower tier or a different financing term first.
Q.What should you say when following up on an HVAC quote?
Something the customer did not have before - the monthly payment they asked about, an answer about the ductwork, an open install date, a promotion deadline. Avoid "just checking in". Ask directly where they are landing - price, timing or the options - and respond to the real objection. If they bought elsewhere, thank them and ask what made the difference.
Q.Should you follow up on declined HVAC repair estimates?
Yes, on a shorter sequence. In a shop running 600 service calls a month where 10 percent end with a declined repair, closing 20 percent of those at an $800 average is about $9,600 a month. Declined repairs on older systems are also replacement leads: flag them for the comfort advisor with the technician's photos and notes.
