How much does an HVAC answering service cost? 2026 prices and a full year for a 3-truck shop

A live HVAC answering service costs about $2,538 to $8,640 a year for a small shop that forwards 600 calls across a year with a summer and a winter rush. That's our example year on one plan all year, priced from five US services' own price lists, checked November 8, 2026. Month by month, on the cheapest plan for that month, the same shop pays from $151.75 in a quiet spring month to $810 in July, depending on the company.

Our example shop has a summer rush and a winter rush, with quieter months in between. So the useful number isn't one month's bill. It's the year, and whether your plan fits July without wasting money in April.

What does each answering service charge?

The plan prices from each company's own page, per month, before taxes, checked November 8, 2026. The last column matters most for an HVAC shop: whether you can change plan when the season changes.

PATLive also sells bigger plans, up to 5,000 minutes for $6,899. Abby says overage is billed “at your plan's Abby Minute rate” but doesn't print it in dollars, and Ruby doesn't publish an overage rate. The plumbing version of this table, with the same five companies, is in how much a plumbing answering service costs.

Why does an HVAC shop need to price a whole year?

Because a plan that fits your busiest month is too big for half the year, and a plan that fits April gets expensive in July. You have three ways to buy:

• One plan sized for your average month, and pay overage in summer and winter. Only works where the overage rate is published (MAP, PATLive, Smith.ai).
• One plan sized for your busiest month, and pay for minutes you don't use in spring and fall.
• Change plans with the season, if the company allows it. PATLive says it has no contracts and you can upgrade, downgrade or cancel any time (PATLive). Smith.ai changes your plan by email and bills the new one from the next month (Smith.ai). Abby says you can move up a plan any time; its page doesn't say how moving down works. Ruby's and MAP's pricing pages don't cover changing plans.

What would a 3-truck HVAC shop pay in a year?

Our example shop forwards the calls it can't take on a job, plus everything after 6 PM. It sends the service 30 calls a month in spring and fall, 60 in winter and 80 in summer: 600 calls a year. These are our round numbers to show how the seasons change the bill, not a forecast. We use 2.5 minutes a call, the same rule of thumb PATLive prints on its own page (50 minutes is “about 20 calls”).

The cheapest plan in each season

The year: one plan all year, or change with the seasons

• A published overage rate is worth a lot to a seasonal shop. On MAP and PATLive, the best single plan is a small one (Business, 100 minutes) and you pay overage in the rush months. Ruby and Abby don't publish a dollar rate, so in our sums you'd have to buy the 200-minute plan all year to be safe: $8,640 on Ruby and $7,188 on Abby. Their real overage rate may be lower; get it in writing.
• On Abby and Ruby, changing plans with the season would save the most, if they allow it. (MAP's page doesn't say either, so its seasonal total is also an ask.) If Ruby let you drop to 100 minutes for spring and fall, the year would cost $6,690 instead of $8,640; on Abby, $5,568 instead of $7,188. Neither page says you can, so ask before you sign. PATLive, which says you can change plans, saves $343.50 a year by moving between plans.
• Per-call pricing gets expensive in the rush. Smith.ai's Starter is $300 for 30 calls, and a summer month of 80 calls costs $810 on Basic. Smith.ai gives 10% off if you pay for 12 months up front; our year totals use monthly prices.

Add the extras where a company charges them per call. Smith.ai lists appointment booking at $1.50 a call, a text or Slack alert at $0.50 (plus $0.25 for each extra ping) and recording at $0.25 (Smith.ai). PATLive lists call transfers and scheduling as included. MAP's page says “custom scripts and workflows tailored to your business come with additional fees” and that round-the-clock or holiday coverage can “significantly add to your monthly expenses” (MAP), so ask MAP what a gas-smell and no-heat script adds. Ruby says there are no extra fees for setup, customization or coverage during certain periods (Ruby). Abby lists no setup fee and counts a minute answered by its AI as half an Abby Minute, so a mix of human and AI answering would cost less than our sums (Abby).

What should an HVAC answering service do with your calls?

The price only matters if the service handles an HVAC call the way you would. Before you sign, send them your rules and ask them to read them back:

• Gas smell, a CO alarm going off, or anyone feeling sick or dizzy: the caller is told to leave the house now and call from outside. That follows the U.S. Consumer Product Safety Commission: for gas, leave immediately and contact the gas authorities from outside without switching lights or phones (CPSC winter safety tips); for suspected carbon monoxide, get to fresh air and call 911 (CPSC carbon monoxide center). The words: “Please hang up, leave the house now, and call 911 or your gas utility from outside.” Book nothing until it's been made safe.
• No heat or no cooling: who's in the house (a baby, someone elderly or sick) and how cold or hot it is inside. Your temperature rules decide whether it rings your on-call phone tonight or goes in the first slot tomorrow.
• Everything else: name, address, the number read back, what the unit is doing, and your service-call fee in your exact words.

We wrote these out as a one-page script with a fill-in on-call rules table in HVAC after-hours calls: no heat, no AC, and what can wait until morning. Then forward only the calls you miss (how to forward your calls).

How do I price my own year? A 15-minute worksheet

1. Calls you'd forward in a quiet month (April or October): ____ (missed calls in your phone log for two weeks, doubled, plus after-hours calls).
2. The same for your worst summer month (last July or August): ____.
3. The same for your worst winter month: ____.
4. Average call length from your phone bill or carrier app: ____ minutes (use 2.5 if you can't find it).
5. Minutes for each of lines 1 to 3 = calls × line 4: ____ / ____ / ____.
6. For each service, one plan all year: quiet-month cost × 6 + summer cost × 3 + winter cost × 3 = ____.
7. The same if you change plans each season, only where the company says in writing that you can: ____.
8. Per-call extras (booking, alerts, transfers, recording) × a year's calls: ____.

Questions to ask before you sign

• “Can I move down a plan in April and back up in June? Is there a fee or a notice period?”
• “What's the dollar price of an extra minute on the plan I'm looking at?” (Ruby and Abby don't print it.)
• “How do you round a call: by the second, 30 seconds or a full minute?” We didn't find it on any of the four per-minute pages.
• “In a heat wave, when the calls double in an afternoon, how long does a caller wait?”
• “A caller says she smells gas at 11 PM. What exactly do your people say?”
• “Do you ring my on-call phone for a no-heat call with a baby in the house, and is the transfer extra?”
• “Is a custom script for HVAC extra?” (MAP's page says custom scripts cost more.)

Do I need a live person or a virtual assistant?

In our view, a live receptionist is better at the hard call: the upset customer whose system you put in last year, or the caller who can't say which unit stopped. If those are most of your missed calls, a live service earns its price. AI lines cost less (see our AI receptionist price list). Jobber's AI Receptionist, for example, is a $29-a-month add-on on top of a Jobber plan (Jobber pricing); the plans and what a conversation is are in our Jobber pricing breakdown. They're virtual assistants and callers should be told so.

Voxlivo is our product: an after-hours and overflow line for HVAC shops that says it's a virtual assistant, takes the name, address and what's broken, books into one Google Calendar and emails you a summary. Growth is $99 a month for 200 minutes and also puts a real emergency call straight through to your on-call phone; extra minutes are $0.25, with no setup fee (pricing). Priced the same way, the example year above would be $1,188 on Growth, for an AI line, not a live person. Call (720) 783-3138 to hear it first. More on our answering service for HVAC page.

Questions owners ask

How much is an HVAC answering service a month?

For our example shop, $151.75 to $395 in a quiet month of 30 calls, and $276.50 to $810 in a summer month of 80 calls, across the five live services above, before per-call extras. Price your own busy and quiet months with the worksheet.

Do HVAC answering services charge more in summer or winter?

None of the five pages lists a seasonal surcharge. You pay more in the rush because you use more minutes or calls. PATLive and Ruby say nights, weekends and holidays are included; MAP warns that round-the-clock and holiday coverage can cost more.

Can I use an answering service only during the busy season?

PATLive, Smith.ai, Abby and MAP all say no long-term contracts (Ruby's pricing page doesn't say), so in principle you can start in June and stop in September. Ask about setup and cancellation notice first. Forwarding is set on your own phone, so you can switch it on and off yourself.

Is it cheaper to pay overage or buy the bigger plan?

Often overage. In our example, PATLive's 100-minute plan with overage in the rush months ($3,208.50 a year) beats keeping a 200-minute plan all year ($4,188). That only works where the overage rate is published.
