What an answering service costs, and where it stops

Most of the companies selling call answering will not tell you the price until you sit through a demo. Smith.ai posts it on a public page, in per-call numbers you can check. That makes them worth a close look, because a published price is the one claim no one can dress up.

So this is not a hit piece. It is the teardown we would want if we were the one buying: what an answering service does for an HVAC contractor, what it costs as published, and what it leaves for someone else to do.

What Smith.ai actually does

They run two products that answer the same phone. The AI receptionist handles routine scheduling and common questions about services and pricing. The live virtual receptionist handles what needs judgement: emergency coordination in bad weather, upset customers, warranty and billing conversations.

For HVAC specifically they collect structured intake: system type, system age, whether it is a repair, maintenance or a new install, urgency, property details and the preferred window. On the Housecall Pro integration, inbound callers are matched to existing or new client records, and call summaries and appointment bookings are logged into the account.

It is a real business, not a two-week startup: they list 5,000+ customers, with 4.8 on Clutch, 4.9 on G2, 4.8 on Capterra and 4.7 on Trustpilot. That is a better track record than most of the AI receptionist crowd, and it matters if your phone is the only way customers reach you.

What it costs, as published

These are the list prices on their AI receptionist and virtual receptionist pages, checked on 12 November 2026. They will change, and a quote may differ, but the shape of the pricing is the point.

AI receptionist

• Free: $0 a month, 25 calls, then $3.00 a call.
• Pro: $150 a month, 75 calls included, about $2.00 a call, extra calls at $2.50.
• Enterprise: $500 a month, 300 calls, about $1.67 a call, extra calls at $2.17.

Live virtual receptionist

• Starter: $300 a month for 30 calls, overage $11.50 a call.
• Basic: $810 a month for 90 calls, overage $10.50.
• Pro: $2,100 a month for 300 calls, overage $8.50.
• Booking into your calendar is an extra $1.50 a call on the human plans. A follow-up message after the call is $0.50.

Put your own week into those numbers

Say you miss around 35 calls a month. On the AI Pro plan that is $150, all of it inside the included volume. On the human Starter plan you buy 30 calls for $300 and pay $11.50 for each of the next five, which lands near $357, plus $1.50 for every call that turns into a booked visit.

That is not a lot of money. At an average job value of $480, one recovered job covers three months of the AI plan and most of a month of the human one. If calls are going unanswered, this is the cheapest fix on the list, and it is honest to say so.

Where it stops

The service answers the call, qualifies it and books it. Then the call ends, and four things still have nobody doing them.

The quote that goes quiet. You send a price, the customer intends to reply and does not. An answering service can send a follow-up message about the call ($0.50), which is not the same as chasing a quote on day three, day seven and day fourteen until it books or says no. That work belongs to whoever owns the pipeline, and right now that is you.

The customer who wants an update. Job updates, the on-my-way text, the questions people ask after the fact, the review request when the job closes. None of that is on the call, so none of it is in scope.

The paperwork after the visit. Job notes, quotes, invoices, the same address typed into a fourth system. An answering service takes calls. It does not close out work.

The record. Smith.ai's Housecall Pro connection logs the call and the booking, which is useful. What it does not do is keep one record that the rest of the office reads and writes. It also decides whether adding the next tool next year is a week of work or a migration.

When one part is the right buy

Be honest about your size. If you are one van, or two, and the only thing going wrong is a missed call at 6pm, buy the answering service. It is live in a day, it needs no build, and $150 a month against a single recovered install is a rounding error. The same applies if you want a human voice and no AI, which is a legitimate preference in a trade built on trust.

One part is also right when the rest of the office is already handled: someone part-time covering the inbox, a scheduling tool everyone actually uses, quotes chased by an office manager who takes it seriously.

When one part is not enough

The test is not how many calls you miss. It is whether the work stops at the phone. Three signs it does not:

• You are paying to make the phone ring, and the quotes you send afterwards go unanswered.
• Your office spends the last hour of the day typing things a system already knows.
• You cannot say, without logging into three tools, what happened to the lead from Tuesday.

If any of those is true, an answering service fixes the cheapest problem and leaves the expensive one. That is not a criticism of the product. It is the difference between buying a part and buying the office.

Three questions for any vendor, including us

• What happens at 2am with a burst pipe? The right answer names a human and a path, not a promise that the AI handles everything.
• Where does the record live? If the answer is a dashboard you log into, ask what reads it when you are not looking.
• What does leaving cost? Ask for the exit before you sign, and how long your data takes to come out.

If you want the call answered, Smith.ai is a reasonable place to start, and their pricing page is worth reading before anyone, including us, quotes you a number.

If you want the calls, the quotes, the customer messages, the paperwork and one record behind them, that is the whole office, and it is what we build. Book a front-office audit and we will look at your calls, your leads and your admin, then tell you which part is actually costing you money. Sometimes it is one. We will say so.
