HVAC scheduling software that answers the phone
HVAC scheduling software is the digital platform U.S. heating and cooling contractors use to dispatch techs, drag-and-drop jobs onto a live calendar, route trucks with GPS, match skills to work orders, track equipment and service agreements, quote repairs, and get paid, think Housecall Pro, Jobber, ServiceTitan, FieldEdge, Workiz, Service Fusion, Sera, or BuildOps. They're excellent at managing a job once it's on the calendar. But the average HVAC contractor misses 27% of inbound calls, 35%+ during peak season. ServiceAgent is the missing layer: an AI voice agent that picks up every call in under 2 seconds, qualifies AC and furnace jobs 24/7, and books them straight into your HVAC scheduler, in English or Spanish.

What is HVAC scheduling software?
A digital platform that automates your HVAC service operation, from emergency dispatch to preventive maintenance, replacing paper schedules, clipboards, and phone-tag. It's the system that turns an inbound request into a confirmed, routed, invoiced job.
Drag-and-drop dispatch board
A live calendar dispatchers use to assign techs, reschedule, and visualize truck coverage. Updates in real time across web and mobile.
GPS tracking & route optimization
Fuel-efficient routing and live tech location. Industry data: route optimization can add 2 to 3 jobs per tech per day.
Skills-based assignment
Matches the right tech to the right job: heat-pump certified, EPA 608, commercial rooftop, ductless mini-split, so dispatch doesn't have to memorize the org chart.
Flat-rate pricebook & estimates
Good / Better / Best repair and replacement options built into the tech's mobile app. Financing links, signatures, deposits handled on-site.
Maintenance agreements & equipment tracking
Recurring tune-up schedules, per-unit service history by serial number, reminders that auto-book the next visit. Where recurring HVAC revenue actually lives.
Invoicing, payments & QuickBooks sync
One-tap invoicing, credit-card + ACH in the field, and accounting sync to QuickBooks Online or Desktop. Closes the loop from call to cash.
Every tool on this page does some mix of the above. What none of them do is pick up the phone before the schedule gets populated, which is why we built ServiceAgent.
Your HVAC scheduling software can't schedule a call no one picked up
Every "HVAC scheduling software" Google ranks, Housecall Pro, ServiceTitan, Jobber, FieldEdge, Workiz, Service Fusion, Sera, BuildOps, was built to move jobs around a calendar after a dispatcher already typed one in. Industry data tells the real story: the average HVAC contractor misses 27% of inbound calls, and in peak cooling and heating season that jumps to 35%+. HVAC shops doing $500K to $2M in revenue are losing $45,000 to $120,000 a year, $300,000+ at peak, straight to voicemail.
- 95°F afternoon in Phoenix or Dallas, 3 to 8 truck shops field 100 to 200 inbound calls per week. Most dispatchers can physically answer 60 to 80.
- Sub-freezing night, furnace fails, homeowner calls 4 HVAC companies in 8 minutes. The first to pick up wins a $4K to $15K system replacement.
- After 5 p.m., weekends, and holidays, the exact hours most no-heat and no-cool calls come in, your phones go dark.
- Live answering services read a generic script, can't see your dispatch board, can't price a diagnostic, and bill $1.50+ per minute.

Meet ServiceAgent
AI front desk for your HVAC scheduling stack
You keep your existing HVAC scheduling software. You stop missing revenue. ServiceAgent sits in front of Housecall Pro, Jobber, ServiceTitan, FieldEdge, or Workiz and answers every inbound call the way a senior HVAC dispatcher would, but 24 hours a day, in English or Spanish, and for a fraction of the cost of a live answering service.
What changes the moment you flip it on
Your number still rings, but instead of rolling to voicemail or a generic operator, it's picked up by an HVAC-trained AI agent in under 2 seconds. The agent qualifies the job (no cool, no heat, thermostat issue, maintenance tune-up, install quote), checks your live dispatch board, slots the appointment, texts the homeowner a confirmation, and logs every detail into your CRM.
Your dispatcher only touches the calls that need human judgment. Your techs stop fielding new-lead calls from a ladder. And the revenue that used to walk to the next HVAC company in the search results starts landing on your calendar instead.
Every call picked up, including peak and after-hours
2-second pickup, no hold music, no IVR. Summer heat waves, winter cold snaps, nights, weekends.
HVAC-trained, not a generic bot
Knows condenser, evaporator coil, heat pump, R-410A, SEER, air handler, ductwork, so callers feel heard, not routed.
Books directly into your HVAC scheduler
Reads live availability in Housecall Pro, Jobber, ServiceTitan, or FieldEdge and slots the diagnostic or tune-up automatically.
Routes real emergencies to real people
No cool in 100°F, no heat in a freeze, gas smell, CO alarm, warm-transfers or pages the on-call tech. Everything else gets booked cleanly.

ServiceAgent, the AI front desk for HVAC companies
ServiceAgent is the only tool on this list whose job is to pick up the phone. An AI voice agent trained on HVAC workflows answers in under 2 seconds, qualifies the job, checks your scheduler, and books the work, 24/7, in English or Spanish.
Unlike a live answering service, it doesn't bill per minute, doesn't read a generic script, and doesn't email you a transcript hours later. It runs alongside your existing Housecall Pro, Jobber, or ServiceTitan, not instead of them.
Pros
- Answers 100% of calls, including peak AC season & after-hours
- HVAC-trained on U.S. terminology, brands & workflows
- Books directly into Housecall Pro / Jobber / ServiceTitan
- Full transcripts + audio + auto-tagged job data
- English + Spanish on the same call
- Flat monthly fee, not per-minute
Cons
- Not a full scheduling tool, you still need an FSM
- Best for shops doing 500+ calls / month
- U.S. & Canada only (for now)
Housecall Pro, the go-to scheduler for residential HVAC
Housecall Pro is the most widely adopted HVAC scheduling software for residential and light commercial contractors. Drag-and-drop dispatch board, "good/better/best" flat-rate pricing, maintenance agreements, GPS vehicle tracking, and automated review requests make it easy to onboard, most HVAC shops go live in a day.
Housecall Pro publishes customer stats of 35%+ monthly revenue growth. It's a strong foundation for HVAC, and pairs cleanly with ServiceAgent: Housecall Pro owns the calendar, ServiceAgent owns the inbound calls that would otherwise hit voicemail.
Pros
- Fastest HVAC onboarding in the category
- Strong residential mobile app
- QuickBooks Online sync is tight
- Online booking widget & review automation
Cons
- Reporting thins out as teams grow
- Phone handling is voicemail-only
- Pricing scales quickly per seat
- Commercial HVAC features are lighter
Jobber, quick quote-to-paid for growing HVAC shops
Jobber is a clean, opinionated HVAC scheduling tool with standout quoting, automations, and a self-serve client hub. Features include AI-drafted estimates, fuel-efficient smart routing, a Receptionist AI add-on, and automated review requests. They claim invoices paid 4x faster. Current plans: Core $29/mo (1 user), Connect $129/mo (up to 5), Grow $249/mo (up to 15), Plus $349/mo.
Where Jobber shines: getting an AC replacement quote approved and paid fast. Where ServiceAgent complements it: HVAC-specific call triage, emergency routing, and bilingual answering that go deeper than a generic receptionist bot.
Pros
- Clean UX and client portal
- Fast quote-to-payment flow (they claim 4x faster payouts)
- Strong automation library
- Polished mobile app
Cons
- Less depth for commercial HVAC
- Receptionist AI is light on HVAC triage
- Not built for enterprise dispatch
- Top-tier plan price jumps sharply
ServiceTitan, enterprise-grade for mid-market & commercial HVAC
ServiceTitan is the deepest platform in the HVAC category. Dispatch optimization, job costing, equipment & serial tracking, maintenance agreements, replacement sales presentations, marketing attribution, and dashboard-grade reporting. It's what most shops move to once they outgrow Housecall Pro or Jobber.
Implementation typically runs multiple weeks and pricing is quote-only. ServiceTitan customers use ServiceAgent to absorb peak-season overflow and after-hours call volume without hiring a second dispatch shift.
Pros
- Deepest reporting & dashboards in the category
- Strong dispatch optimization
- Memberships, agreements, replacement sales
- Marketing attribution built in
Cons
- Long implementation (3 to 6 weeks)
- Custom enterprise pricing, not published
- Overbuilt for <5-tech shops
- Steep learning curve for dispatchers
FieldEdge, QuickBooks-Desktop-heavy HVAC & plumbing shops
FieldEdge is purpose-built for HVAC and plumbing companies migrating off paper, spreadsheets, or legacy desktop systems. Customer and equipment history (by serial number), a flat-rate pricebook, maintenance agreement tracking, and one of the strongest QuickBooks Desktop integrations on the market.
UI is more traditional than Housecall Pro or Jobber, but HVAC dispatchers coming from the old-school world tend to prefer the layout. No built-in call handling, which is where ServiceAgent slots in.
Pros
- Strong QuickBooks Desktop sync (legacy shops love it)
- Equipment & serial tracking
- Reliable dispatch board
- Trusted name in HVAC / plumbing
Cons
- UI feels dated vs newer tools
- No built-in call handling
- Limited automation out of the box
- Pricing not published publicly
Workiz, affordable scheduler with call tracking baked in
Workiz is a budget-friendly all-in-one for smaller HVAC shops. You get dispatch, invoicing, estimating, a light CRM, built-in call tracking, and SMS in a single subscription. Popular with HVAC companies that want one tool to run ops and marketing.
Call tracking tells you who called and whether you missed it. It doesn't answer the call, that's still voicemail. ServiceAgent layers on top of Workiz to actually pick up the phone.
Pros
- Built-in call tracking + SMS
- Reasonable pricing for small teams
- Decent mobile app
- All-in-one for ops + marketing
Cons
- Call tracking is not call answering
- Less depth for commercial HVAC
- Reporting is limited
- Smaller integrations ecosystem than Jobber / HCP
Service Fusion, flat-fee scheduling for growing HVAC teams
Service Fusion charges a flat monthly fee regardless of user count, a very different model from Housecall Pro or Jobber where costs scale per seat. For HVAC shops with 10+ users that can pencil out to a real saving. Includes online booking, drag-and-drop dispatch, GPS tracking, built-in messaging, and a flat-rate pricebook.
The trade-off: UI is heavier than newer tools, and reporting depth does not match ServiceTitan. Pairs well with ServiceAgent for shops that want to absorb call volume without also paying per seat for a receptionist.
Pros
- Flat fee, unlimited users
- GPS tracking + built-in messaging
- QuickBooks Online and Desktop sync
- Solid online booking tool
Cons
- UI feels heavier than newer tools
- Reporting is shallower than ServiceTitan
- Mobile app is less polished
- Implementation can take a few weeks
BuildOps, the mid-market to enterprise commercial HVAC platform
BuildOps is tailored for commercial HVAC, mechanical, and refrigeration contractors. Dispatch, preventive maintenance agreements, project management, quoting for equipment replacements, and enterprise financial integrations like Sage Intacct and Acumatica. Typical customer does $5M+ in revenue.
Not a fit for 2-truck residential HVAC shops, but the dominant choice if your book is heavy on commercial service agreements. ServiceAgent adds inbound call coverage on top of BuildOps without changing your dispatch flow.
Pros
- Commercial HVAC-specific workflows
- Strong service agreement + project tracking
- Enterprise accounting integrations
- Modern, clean UI
Cons
- Overbuilt for residential shops
- Enterprise pricing, not public
- Longer implementation timeline
- No inbound call handling
Sera, AI-assisted scheduling built for residential HVAC
Sera pitches itself as the scheduler that "actually increases revenue per tech." Its AI-assisted dispatch proposes the most profitable slot given tech skills, location, and average ticket size, a meaningful edge during peak HVAC season when every slot counts.
Trade-off: Sera is younger than ServiceTitan or Housecall Pro, so the integrations list is thinner. Fit is best for residential HVAC shops between 4 and 25 techs that want AI scheduling without ServiceTitan-level complexity or price. Drops in cleanly with ServiceAgent, so every inbound call gets booked, not just every job dispatched.
Pros
- AI-assisted dispatch for revenue optimization
- Real-time job-costing visibility
- Built specifically for the trades
- Simpler pricing than ServiceTitan
Cons
- Smaller integrations ecosystem
- Less polished than Housecall Pro / Jobber UI
- Pricing climbs fast past 10+ techs
- No inbound call handling
FieldCamp, AI-powered scheduling at an approachable price
FieldCamp is frequently listed as the "best overall" pick on 2026 HVAC scheduling review sites, largely because it combines AI-powered scheduling, dispatch, CRM, and invoicing with an actual free plan to start on. Contractors moving off paper or spreadsheets can test the whole workflow before paying a cent.
For HVAC shops priced out of ServiceTitan and looking for something smarter than Housecall Pro's basic tier, FieldCamp is worth a look. Its AI scheduling doesn't answer calls, ServiceAgent does that, but once a job is created, FieldCamp handles routing and dispatch cleanly.
Pros
- AI scheduling in a free / low-cost tier
- Covers CRM + scheduling + invoicing
- Usage-based pricing model
- Fast onboarding
Cons
- Newer platform, smaller community
- Reporting depth less mature than incumbents
- Limited enterprise controls
- No inbound call handling
ServiceTrade, commercial HVAC + fire & life safety specialist
ServiceTrade is purpose-built for commercial HVAC, mechanical, and fire & life safety contractors. Its edge is in long-tail recurring revenue: service agreements, per-asset maintenance histories, deficiency tracking on equipment lists, and customer-facing portals that let building managers see tickets without a phone call.
Not a fit for 1 to 5 truck residential shops. For mid-market commercial HVAC companies whose revenue is 60%+ service agreements, few competitors come close. ServiceAgent sits on top, absorbing overflow inbound service requests during peak-season heat waves.
Pros
- Strong service-agreement & asset management
- Customer-facing portal cuts inbound tickets
- Proven at 100+ tech scale
- Purpose-built for commercial HVAC
Cons
- Overbuilt for residential-only shops
- Custom pricing, not public
- Longer implementation timeline
- No inbound call handling
Pay less than one missed AC diagnostic per month
Most HVAC shops recover the entire ServiceAgent subscription from the first after-hours call it books. Here's how the three real options stack up.
| ServiceAgent | Human answering service | In-house dispatcher | |
|---|---|---|---|
| Monthly cost | Custom pricing | $1.25 to $2.00 per minute ($900 to $2,200 / mo typical) | $3,800 to $5,400 / mo fully loaded |
| Coverage | 24/7/365 | 24/7 (often with wait times) | Business hours only |
| HVAC-trained | Yes, condenser, heat pump, SEER, refrigerant | Generic script | Depends on hire |
| Books into Housecall Pro / Jobber / ServiceTitan | Yes, auto, on your dispatch board | Emails you a message | Manual entry |
| Peak-season overflow | Unlimited | Queue / hold times | Hard-capped by headcount |
| Setup time | ~1 day | 1 to 2 weeks | 3 to 6 weeks to hire + train |
| Free trial | $20 in credits · no card | None typical | N/A |

Six things every HVAC shop needs, none of which your scheduler does
24/7 AI call answering
A human-sounding voice agent picks up in under two seconds. Trained on HVAC terminology, condenser, evaporator coil, heat pump, R-410A, SEER, so homeowners never feel routed to a bot.
Direct booking into your HVAC scheduler
Reads live availability from Housecall Pro, Jobber, ServiceTitan, or FieldEdge and slots the homeowner into an open diagnostic or tune-up window, no dispatcher needed.
Emergency triage & routing
No cool in 100°F, no heat in a cold snap, gas smell, CO alarm, the agent qualifies urgency and can text the on-call tech, warm-transfer to dispatch, or book same-day.
English & Spanish, 100% of the time
Serves the U.S. HVAC market as it is. Switches between English and Spanish on the same call if the homeowner does, critical in TX, CA, FL, AZ, NV.
Full transcripts & recordings
Every call comes back as searchable text plus audio, with contact, equipment type, address, urgency, and booked slot auto-tagged and pushed straight into your CRM.
Follow-up SMS & review requests
Texts the homeowner an appointment confirmation seconds after booking, reminds them the day before, and nudges a Google review 2 hours after the tech clocks out.

HVAC scheduling software, answered
HVAC scheduling software is a digital platform that automates the full HVAC service operation, emergency dispatch, preventive maintenance, quoting, invoicing, equipment tracking, replacing paper schedules, clipboards, and phone-tag. The most widely used tools in the U.S. are Housecall Pro, Jobber, ServiceTitan, FieldEdge, Workiz, Service Fusion, Sera, FieldCamp, and (for commercial HVAC) BuildOps and ServiceTrade. ServiceAgent sits one layer earlier in the flow: it answers the calls those tools schedule.
At minimum: a drag-and-drop dispatch board, GPS tracking with route optimization, skills-based assignment, a flat-rate pricebook, maintenance agreement & equipment tracking, a tech mobile app (iOS + Android), online booking, review automation, and a tight QuickBooks sync (Online and/or Desktop). For commercial HVAC also look for multi-day / project scheduling and per-asset service history. None of these, by themselves, pick up an inbound phone call, which is why pairing any of them with an AI receptionist meaningfully changes peak-season economics.
Industry data puts the average HVAC miss rate at roughly 27%, climbing to 35%+ during peak cooling and heating seasons. For shops doing $500K to $2M in annual revenue, that commonly equates to $45,000 to $120,000 in lost jobs per year, and $300,000+ during peak. A single missed replacement call can be worth $8,000 to $15,000 all on its own. The math is why shops pair Housecall Pro, Jobber, or ServiceTitan with ServiceAgent.
No, and intentionally so. Those platforms are field service management and scheduling tools, and they're very good at that. ServiceAgent is an AI call-answering layer that plugs into them. You keep your dispatch, invoicing, and reporting, and add a 24/7 HVAC-trained AI receptionist on top. See pricing →
It varies widely. Jobber starts around $69 / mo and scales to $349 / mo. Housecall Pro runs roughly $49 to $279 / mo per plan. ServiceTitan is custom-quoted and typically starts higher. BuildOps is enterprise-priced for commercial HVAC. ServiceAgent uses custom pricing based on your call volume and service area, usually less than a single month of a human answering service.
Both. 1-truck HVAC owners use ServiceAgent because they can't pick up while elbow-deep in a furnace. 40-truck shops use it because they can't staff peak-season dispatch. The break-even point is roughly 500 inbound calls per month, which most HVAC shops clear easily during cooling and heating seasons.
Indirectly, ServiceAgent writes the booked job into your HVAC scheduler (Housecall Pro, Jobber, ServiceTitan, FieldEdge, Service Fusion), and the scheduler handles the QuickBooks sync (Online or Desktop, depending on the platform). This keeps your accounting pipeline clean.
Yes, this is the core use case. ServiceAgent qualifies urgency mid-call (no cool, no heat, gas smell, CO alarm, water leak at the air handler), matches against your on-call rotation, and can text the right technician, warm-transfer to a dispatcher, or book an emergency slot, all within 30 seconds.
Yes. ServiceAgent operates fluently in English and Spanish and will switch mid-call if the homeowner switches. This matters a lot in Texas, California, Florida, Arizona, and Nevada HVAC markets, where a meaningful share of residential calls start in Spanish.
Only if you want them to. The voice is intentionally warm, human-sounding, and trained on natural HVAC conversations. You can choose to disclose it's an AI agent up front or let the caller ask.
Most HVAC shops go live in under a day. You forward your number, upload your service area and diagnostic pricing, connect your scheduler, and the first live call runs through the dashboard, usually within 90 minutes of going live.
Yes, $20 in free credits, no credit card required. That's typically enough to cover your first 30 to 60 live calls so you can hear the quality before subscribing. See pricing →
