Missed calls and follow-up for air duct cleaning companies: text-back, answering and speed to lead
What a missed call costs a duct cleaning company, why this trade loses more to voicemail than most, the text-back that recovers them, and the follow-up sequence after a quote.
A duct cleaning crew is in an attic, a crawlspace or a basement with a vacuum running for most of the workday. The owner is often on the crew. The phone rings, nobody hears it, and the homeowner who was ready to book calls the next listing. In this trade the next listing is frequently the $49 company, which has a call center that answers on the first ring. The call you missed became their bait-and-switch job.
Run the missed call calculator with your real numbers before reading further. At a $450 average ticket, a company that misses 30% of 60 calls a month and would have booked half of them is leaving around $4,000 a month on the table. That is more than most duct cleaners spend on ads.
How many calls you are actually missing
Most owners guess 10%. When we put call tracking on a one or two truck company, the number is usually between 25% and 45% during working hours, and close to 100% after 5 p.m. and on weekends. Duct cleaning has a specific problem: jobs are long, three to five hours, and the vacuum is loud. A plumber on a 40-minute call hears the phone. A duct tech halfway through a trunk line does not.
The first fix is knowing the number. Put a tracking number on your Google profile and your website, or use your phone carrier's call log, and count missed calls for two weeks. Count voicemails separately; most callers do not leave one.
The text-back that recovers the call
The single highest-return change in this guide: when a call goes unanswered, a text goes to the caller within 30 seconds. Automatically. The text should sound like a person, mention duct cleaning, and ask one question.
"Hi, this is Marcus at [Company]. Sorry we missed you, the crew is on a job with the vacuum running. Are you looking at whole-house duct cleaning or a dryer vent? I can get you a price right here."
That message does four things. It confirms the caller reached a real company. It explains the miss in a way that proves you do real work. It asks a question the homeowner can answer with a thumb. And it offers a price, which is what they called for.
Reply within five minutes, from a phone, with a range and a next step: "For a single-system home around 2,000 square feet it is $395 to $495, two to four hours. I have Thursday morning or Saturday at 8. Which works?"
Companies that put this in place typically recover 30% to 50% of missed calls into conversations and book a good share of those. The text-back setup costs $30 to $100 a month on most platforms, or it is included in a CRM.
Answering the phone when you can
Text-back is a net, not a replacement for answering. Options in rough order of cost:
- Route the business line to the office person or a spouse during the day, and give them a one-page script with the price ranges. $0.
- A part-time answering person for 8 a.m. to 6 p.m., Monday through Saturday, often a retiree or a stay-at-home parent in your town. $600 to $1,200 a month.
- An answering service that uses your script and books into your calendar. $150 to $400 a month. Make sure they can give a price range; a service that only takes messages loses the caller to the next listing.
- An AI voice agent that answers, quotes the range and books. $100 to $300 a month, and good enough now for a trade with simple pricing. Listen to its calls weekly.
Whatever answers, it must say a price range on the first call. A caller who hears "we will have someone call you back with a quote" dials the next company while waiting.
Speed to lead for web and ad leads
For leads that come from a form, Meta ad, or Local Services Ads, the clock is even shorter. A lead contacted inside five minutes is several times more likely to book than one contacted in an hour, and a lead from the previous evening is mostly gone by morning.
Set up:
- Form and Meta leads trigger a text within 60 seconds, with the same question and price range as the missed-call text.
- Local Services Ads leads ring your phone and, if missed, trigger the text-back. Google scores your responsiveness, and slow answers push your ad down.
- A calendar link in the text so the homeowner can pick a slot without another round trip. Weekend slots fill first in this trade; 56.8% of competitors list Saturday hours and the ones that do take the weekend jobs.
Follow-up after the quote
Half the money in this trade is in quotes that were given and never followed up. A homeowner who got a $475 quote and did not book is still thinking about it a week later, and the only thing that stops them from calling the coupon company is hearing from you.
Sequence after a quote with no booking:
- Day 1, evening: "Thanks for calling today. Quote for the whole-house cleaning was $475, includes both returns and the air handler. Want me to hold Saturday for you?"
- Day 3: a photo text of a before-and-after from this week with one line: "This was a 2001 house like yours."
- Day 7: "Still happy to do it at $475 through the end of the month. Just reply yes and a day."
- Day 30: a plain check-in, then stop.
Four messages, all short, all with the price restated. The price restatement matters because the homeowner is comparing you to an ad that hides its price.
After the job
Two more messages make the whole system pay again. The same day: the review ask with the link, covered in the reviews guide. Eleven months later, for dryer vent customers: "It has been about a year since we cleaned your dryer vent. Same price, $129. Want a morning next week?" Three years later for whole-house customers, with the same structure.
Repeat customers at a known price are the cheapest jobs you will ever book, and most duct cleaners never ask.
Frequently asked
Will customers find the automatic text annoying? Not when it sounds like a person and answers their question. Complaints come from texts that read like a robot or arrive in a burst. One text, in your words, with a price.
What if I run a one-person operation? Then the text-back is the only thing standing between you and the voicemail problem. Set it up before you spend a dollar on ads. The Google Ads guide assumes it is in place.
Does this work for Spanish-speaking callers? Yes, and it is worth having both versions ready. A text-back that detects the caller's language or offers both languages books calls that a voicemail never would.
Missed-call text-back and lead follow-up is one of the services in the free 14-day trial. It is usually live within two days. Text or call (385) 486-5536.
