How should an HVAC company follow up on estimates that didn't close?

The short answer: send the customer a copy of their options the same day, call them within a couple of days to find out what's really holding them up, then follow up a few more times over the next two weeks, and make sure every touch gives them something new. After that, put the estimate on a seasonal list instead of letting it die in a folder.

I'm a licensed HVAC engineer, and I've seen this from both sides. A tech or comfort advisor spends an hour at the kitchen table, measures, writes up good, better and best options, and the homeowner says "let me think about it." Then nobody calls. Two weeks later the homeowner signs with whoever did call. The estimate wasn't lost on price. It was lost on silence.

Why are unsold estimates worth chasing?

Because you already paid for them. The marketing that made the phone ring, the truck roll, the tech's time and the proposal are all spent before the customer says yes or no. A homeowner who let you into the house and looked at real numbers is the warmest lead you'll ever have. They know you, they know the problem, and most of them still need the work done.

How do I figure out what my open estimates are worth?

Use your own numbers. Pull the last 90 days of estimates from whatever you use, even if it's a spreadsheet or a stack of paper, and write down three things:

1. Open estimate dollars. Add up the total of every estimate that wasn't sold and wasn't clearly turned down. Use the option the customer seemed most interested in, not the most expensive one.
2. Your close rate on follow-up. Out of the estimates you did follow up on in the past, how many eventually sold? If you've never tracked it, start now and check again in a month.
3. Your gross margin on installs. What's left after equipment, labor and permits.

Open estimate dollars × your follow-up close rate × your margin gives you a rough idea of the profit sitting in that pile. Even if your follow-up close rate turns out to be small, a few replacement jobs a quarter adds up fast. That number tells you how much time and money it's worth spending to follow up properly.

What should happen before the tech leaves the house?

Good follow-up starts at the kitchen table, not in the office a week later. Before the tech or advisor walks out:

• Ask what's holding them back. "Is there anything that would stop you from moving forward today?" Write the answer down. That's what your follow-up should be about.
• Ask who else decides. If a spouse, parent or landlord needs to see it, offer to walk them through it on the phone.
• Ask how they want to be contacted. Call, text or email. If you plan to text, get a clear yes first and note it.
• Set a specific next step. "I'll call you Thursday afternoon" works better than "let us know."
• Leave something they can share. The written options, photos of what you found and what each option includes.

What does a good follow-up schedule look like?

There's no single right schedule, but this one is a sensible starting point for most residential replacement and repair quotes:

• Same day: a thank-you with a copy of the options and photos, plus one line on what happens next.
• Day 2 or 3: a phone call from the person who ran the call. Answer questions and find out the real objection.
• Around day 7: something new and useful, like a financing option, an honest install date opening, or rebate details that apply to their equipment.
• Day 14: a short, no-pressure check-in. "Still happy to help whenever you're ready."
• After that: move it to a seasonal list and reach out once before the next hot or cold stretch.

Stop the moment someone says no or asks you to stop, and mark it so nobody calls them again.

What should I say when I follow up?

Never just "checking in." Every message should answer a question or give them a reason to reply. Here are a few that work because they're about the customer, not about you:

• "You mentioned the upstairs bedroom never cools down. I attached a note on how each option handles that."
• "You asked about payments. Here's what the monthly cost looks like on the middle option."
• "I had an install slot open up next Tuesday. Want me to hold it for you?" (Only say this if it's true.)
• "Before you decide, it's worth checking which rebates your equipment qualifies for." The ENERGY STAR rebate finder lets a homeowner look up offers by ZIP code, and sending them that link shows you're on their side.

Don't invent urgency. No fake "this price expires Friday." If prices really are going up or a rebate really is ending, say so with the real date. Homeowners can tell when they're being pushed, and it costs you trust.

Who should own the follow-up?

One named person per estimate, with a date for the next touch. When follow-up belongs to "the office," it belongs to nobody. In a small shop that's often the owner or the advisor who ran the call. In a bigger shop it might be a CSR working from a daily list of open estimates.

Whatever you choose, keep a simple record for each estimate: the options and prices, the main objection, the next follow-up date and every touch you've made. If someone is out sick, the next person can pick it up without starting over.

How do I keep follow-up from falling through the cracks?

This is where most shops break down. Not because they don't know what to do, but because summer gets busy and follow-up is the first thing to go. The fixes are simple:

• A daily list of estimates with a follow-up due today, so nobody has to remember.
• Automatic same-day messages with the customer's options and photos, so that step never gets skipped.
• Reminders to the person who owns each estimate when a call is due.
• A seasonal list of lost or stalled estimates that gets one useful message before each peak season.

None of this has to be fancy. What matters is that every estimate gets followed up the same way every time, even in your busiest week.

How does this connect to missed calls?

It's the same leak in a different spot. A homeowner who calls you back to say yes and gets voicemail may sign with the next company. I wrote about how to work out what a missed call costs a home service business. Run both numbers, missed calls and open estimates, and you'll know which one to fix first.

Is it worth paying someone to set this up?

Only if the number you worked out above is bigger than the cost. If you write a handful of estimates a month and already call every one back, you probably don't need help. If you have a pile of open quotes and nobody owns them, closing even one more replacement job a month usually covers the cost. I'm happy to go through your estimates with you and tell you plainly which side you're on.

FAQ

How many times should I follow up on an HVAC estimate?

Usually four or five touches over about two weeks, across phone, text and email, then one check-in before each season. Stop right away if the customer says no.

Should I text customers about their estimate?

Only if they said yes to texts. Ask at the appointment and note it on the estimate.

Should I lower my price to close an estimate?

Not as a first move. Find the real objection first. Often it's timing, the other decision-maker, or monthly cost, and a smaller option or a payment plan solves it without cutting your margin.

What if the customer went with another company?

Thank them, ask what made the difference, and mark it lost with that reason. Their answer will help you close the next estimate.

Does this work for plumbing and electrical quotes too?

Yes. Any trade that writes quotes for bigger jobs, like repiping, water heaters or panel upgrades, loses money when quotes go quiet, and the same steps apply.
