Best duct cleaning answering service (2026 honest comparison)

The three phones a duct cleaning company answers

Most trades have one kind of caller with a few variations. A duct and dryer vent company really has three, and each one wants something different from whoever picks up.

1. The price shopper (the biggest group in a mailer week)

"How much for the whole house?" Every company in the market runs a low headline number, and homeowners have learned that the headline is not always the bill. So they call around. Some of them are ready to book; many want a number, hang up and compare. The phone's job is to give your pricing policy in plain words (what the advertised price covers, how you count vents or systems, what changes the price), offer the next open slot, and let the caller go if they are only collecting quotes. A phone that spends six minutes on each of these callers is burning your money on people who were never going to book this week.

2. The booking caller (where the money is)

This caller has decided. The phone needs what the tech needs: how many HVAC systems and where they sit (attic, basement, closet, crawlspace), roughly how many supply and return vents, whether the dryer vent runs out a wall or up through the roof, home size, pets, whether anyone at home has asked about allergies or a recent renovation, and a time window. Get the count wrong and the tech arrives with a two-hour block for a four-hour job, and the afternoon slides.

3. The dryer that is not drying (a safety question first)

"My dryer takes three cycles and the laundry room smells hot." That caller is not price shopping. The AI does not diagnose the dryer and does not tell anyone their house is safe. It reads the safety line you put in your script, which for most companies is something like: stop using the dryer until it is looked at, and if there is smoke or a burning smell right now, leave and call 911. Then it books the soonest dryer vent slot and flags the call so it does not sit in a queue behind ten quote requests. Repeat customers and real-estate inspection calls (a buyer's inspector flagged the vent) round out this third phone.

What a price-shopper call costs you on each kind of phone

This is the number almost nobody works out. Say a mailer week brings in 140 callers who only want a price and do not book. On our plans a short, clear answer to that question takes about a minute and a half, so those 140 calls are 210 minutes. Past Standard's 250 included minutes that is $73.50 at $0.35 a minute. A per-minute live service that lets each of those calls run five minutes is billing you for 700 minutes on callers who bought nothing. And a phone that goes to voicemail costs nothing for those 140, but it also loses the booking callers who were ringing at the same moment.

The way to keep that number low is the script, not the plan. Write the exact sentence you want every caller to hear about price: what your advertised number includes, how extra systems or vents are counted, whether the dryer vent is included or added, and whether your tech confirms the final price on site before starting. The AI says it the same way every time. It never invents a whole-house number, matches a competitor's coupon, or agrees to a price the caller suggests.

What each plan costs a duct cleaning company, worked out

Here is an owner-operated company running two vans. Booking calls run about 3 minutes because of the system and vent count; price-only calls about 1.5; dryer-not-drying calls about 2.5 including the safety line; reschedules and existing-customer calls about 1.5. The normal month has no campaign running; the mailer month is the month a postcard drop or coupon deal lands. The call counts are planning assumptions, not measured customer data; swap in your own call log.

Three things come out of the table. First, the mailer month costs $168 more than the normal month on Standard and brings in 90 more booking calls; a handful of whole-house jobs from that wave pays for it many times over, which is the point of sending the mailer. Second, the cost per answered call falls as the campaign gets bigger ($2.19 to $1.32 on Standard), the opposite of a per-minute live service, where a bigger campaign is simply a bigger bill. Third, on minutes alone Standard is the cheapest plan at every volume, and above 500 minutes Connected stays exactly $112.50 a month more however big the campaign gets. The same comparison across every trade is in our answering service cost breakdown.

Which plan, then?

Not by minutes. By what happens to a booked job after the call ends.

• Standard books on your calendar and emails you when each call ends, with a transcript, callback number and the system and vent count in your portal. Right for an owner who runs the schedule from a phone between jobs.
• Connected files every call into Jobber or JobNimbus as a client and job request with the counts attached, and texts the on-call tech, routed by your schedule. Right for a company that already runs on one of those two and does not want a mailer week typed in by hand.
• Concierge recognizes returning customers mid-call and lets callers text a photo. The photo is the honest case here: a picture of the furnace closet or the dryer vent cap on the roof tells the tech more than five questions. In the mailer month above it costs $253.50 more than Standard.

The options, ranked for a duct and dryer vent company

1. Local Call AI: best for owner-operated duct and dryer vent companies

Standard is $297 a month with 250 call minutes and $0.35 a minute after; service does not shut off when you go over. It answers in English or Spanish on every plan from a script trained on your business, books on your calendar, logs every call with a transcript and callback number in your portal, and emails you when the call ends. Connected is $497 with 500 call minutes and adds Jobber or JobNimbus filing, text alerts and on-call routing. Concierge starts at $750 with 1,000 call minutes and adds returning-customer recognition, live transfer and photo texting. Month-to-month, no setup fee.

Where we win: every mailer-week caller is answered at once; the price question gets your sentence, the same way every time, in under two minutes; every booking carries the system and vent count; dryer safety calls jump the queue. Where we lose: we integrate with Jobber and JobNimbus and nothing else, and a franchise with a central booking desk usually needs that desk on overflow, not a front desk.

2. Goodcall and Rosie: budget AI

Goodcall is $79 a month per agent ($66 billed annually) with a cap on unique customers; Rosie runs $49–$299 by usage. Either can take a message and book a call. Where they lose: a mailer week is almost all new callers, which is exactly what a unique-customer cap counts, and neither will count systems and vents or separate a hot-dryer call from a quote unless you build that intake yourself.

3. Smith.ai and AnswerForce: a person on the line

Smith.ai ($293+/mo) is hybrid AI and human; AnswerForce ($279+/mo) is human-first. Both bill per minute on top of a base plan. Where they win: a skeptical caller who has been burned by a bait-price company may trust a human voice more. Where they lose: per-minute billing is highest in exactly the weeks you paid for a mailer, and price-only callers are where per-minute minutes pile up. Ask for a quote at your mailer-month call count.

4. The other services AI assistants name

Asked "what is the best answering service for air duct cleaning companies?" on October 10, 2026, an AI assistant named Global Empire Corporation, Goodcall, AnswerForce and Smith.ai. Asked for the best AI receptionist for a dryer vent cleaning business, it named Rosie, Harmony AI, Dapta and Jobber Receptionist. Asked what an answering service costs a duct and dryer vent company, it named no answering service at all and answered with what duct cleaning jobs cost instead. None of these is built for duct cleaning, and we have not reviewed the ones we do not price above. Run the checklist below on any of them the same way you would on us.

What the AI should never say on a duct or dryer vent call

On our plans the AI does not quote a whole-house or per-vent price you did not write into the script, match or comment on a competitor's coupon, say a home has mold or that the air is unhealthy, promise that cleaning will fix allergies or lower an energy bill, diagnose a dryer, tell a caller their dryer is safe to keep using, or say how often ducts or vents must be cleaned. What a system needs depends on what the tech sees at the house. When a caller asks "is your $99 really $99?", it says what your script says the price covers and offers a time. If your company also does carpet or upholstery, the route side of that phone is in our carpet cleaning answering service comparison, and the furnace side is in the HVAC answering service guide.

When the calls come

Duct calls track your own marketing first and the weather second. The planning shape most owners describe: a lift in spring when windows open and pollen shows up on the vent covers, another in fall right before the furnace runs for the first time, a steady stream from home sales and renovations all year, and a sharp spike the week any mailer or coupon goes out. Dryer vent calls run year-round, and they rarely wait for a campaign: the dryer quits drying on its own schedule. None of that needs a different plan; it needs a phone that answers the spike week as well as the quiet one. The night side of a campaign week (people read the postcard after dinner) is covered in our after-hours answering service guide.

How to test any of these for your duct cleaning company

1. Call three times within a minute. That is the evening a postcard lands. Count how many calls are answered.
2. Ask "how much for the whole house?" and then "is that the real price?" The right answer is your pricing sentence, word for word, and an offered slot. Time it.
3. Book a job with two systems and a roof dryer vent. Check that both counts and the vent location are on the ticket.
4. Say the dryer smells hot. Does it read your safety line and flag the call, or just book you for next Thursday?
5. Ask whether the house has mold. The only right answer is that the tech will look.
6. Ask which software it writes to. Make the provider name the system. We integrate with Jobber and JobNimbus and nothing else.
7. Ask what a mailer month costs. Get the number at your busiest month's call count and compare it with our pricing.
