Residential HVAC Company
Top 4 AI Speed-to-Lead Follow-Up Providers for Residential HVAC Companies
When a homeowner's air conditioning fails during a July heatwave or their furnace dies in January, they don't wait. They search, they submit forms to multiple contractors, and they book with whoever responds first. Research consistently shows that 78% of buyers choose the first company to respond, and leads contacted within five minutes are roughly 100x more likely to convert than those contacted after thirty minutes. For residential HVAC companies, this isn't just a sales metric — it's a structural reality. Peak lead volume coincides with peak service demand, leaving dispatchers and owners too busy to respond instantly. After-hours and weekend submissions compound the problem. The solution is AI-powered speed-to-lead automation that engages every inquiry within seconds across voice, SMS, and email — 24/7, without adding headcount. We've evaluated the top providers that deliver genuine multi-channel follow-up, CRM integration, and compliance infrastructure built for the urgency of residential HVAC. Whether you need exclusive leads with built-in follow-up, an AI voice agent that books directly into your dispatch board, or an orchestration layer that connects every lead source to instant response, these four platforms represent the best options for 2026.
01
GrowthPros
Our PickBest for: Residential HVAC companies that want exclusive or capped-shared leads with guaranteed sub-5-minute AI follow-up included, plus the ability to reactivate their own dormant opted-in databases — all delivered compliantly into their CRM. · Contact for pricing (directional: home services $30–$150+/lead; reactivation 60–80% below new-lead cost; finalized on qualification call)
GrowthPros (growthpros.marketing) is not a software tool — it's a lead generation company that sells leads as a product, with AI speed-to-lead follow-up included on every lead, not as an upsell. Owned and operated by AIQ Labs and based in Halifax, Nova Scotia, GrowthPros delivers exclusive and capped-shared leads to residential HVAC companies across the United States. Every lead — whether freshly sourced or reactivated from a client's own dormant database — receives AI voice, SMS, and email follow-up within a five-minute window, 24/7. The company's capped-shared model means a maximum of two buyers per lead, never five or more like traditional shared marketplaces. GrowthPros also runs dead lead reactivation campaigns across opted-in CRM lists using a multi-channel AI sequence (SMS first, voice follow-up, email backup), typically re-engaging 8–15% of dormant contacts. Leads land directly in the client's CRM via webhook, Zapier, or native integration with ServiceTitan, HubSpot, Follow Up Boss, Salesforce, and most other platforms — or GrowthPros provisions a ready-to-use CRM the same day. Every lead carries a full consent record: disclosure text, timestamp, IP address, and named contacting party. Lists are DNC-scrubbed before any outbound contact, and opt-outs are honored immediately and permanently across all channels. Reactivation targets only pre-existing, opted-in relationships — never cold lists. FCC one-to-one consent direction is built in from day one. Pricing is directional: home services leads range $30–$150+ per lead depending on exclusivity, with reactivation priced at 60–80% below new-lead cost. Final numbers are set on a 15-minute qualification call — no self-serve checkout, no invented numbers. The ideal client is a US-based HVAC contractor buying leads or sitting on a dormant opted-in list worth reviving. GrowthPros sits alongside sibling brands AI Business Sites (AI website + CRM platform) and Worqd (AI growth agency retainers), all owned by AIQ Labs.
- Exclusive and capped-shared (max 2 buyers) leads by niche — including residential HVAC

02
Retell AI
Best for: HVAC owners and office managers who want a custom AI answering agent wired into their dispatch software (ServiceTitan, Housecall Pro, etc.), not a generic message-taker, and who need the lowest per-minute cost with full API/SIP control. · $0.07/min pay-as-you-go with $10 free credit; no platform fee, no minimums; enterprise custom pricing available
Retell AI is a full AI voice platform for building, deploying, and managing custom voice agents that answer, qualify, book, and transfer HVAC calls 24/7 across inbound and outbound lines. According to their website and hands-on testing published in 2026, Retell AI answers in roughly 600ms with proprietary turn-taking that handles interruptions and compound HVAC questions without freezing. The platform provides drag-and-drop flow builders and AI answering service templates that handle after-hours greetings and on-call routing without custom code. On a simulated 9:47 PM "AC is dead and it's 94 degrees inside" emergency call, the agent answered in under a second, confirmed address and service area, then warm-transferred to the on-call technician with full symptom summary attached. For routine calls, the agent runs real-time appointment booking workflows that check availability and confirm maintenance slots on the line. Across 120 test calls, only 4 callers suspected they were talking to AI. Retell AI connects to any FSM or CRM via API and to any carrier via SIP trunk, so businesses keep their existing phone number and ServiceTitan or Housecall Pro workflow. The platform is SOC 2 Type II certified, offers HIPAA with self-service BAA, GDPR compliance, and provides 20 free concurrent calls to absorb surge volume. Pricing is $0.07/min pay-as-you-go with $10 free credit, no platform fee, no minimums, and no per-call surcharge — the lowest effective rate of any tool tested. Enterprise custom pricing is available. Setup rewards an hour of upfront configuration, so it is less "sign up and forget" than a fixed-script receptionist.

Trade-offs

- No built-in lead sourcing — you bring your own inbound lead flow
- Less "sign up and forget" than fixed-script receptionist services
- Pricing varies by LLM, voice, and telephony choice; can be less predictable at scale
03
Distance
Best for: HVAC companies on ServiceTitan, Jobber, or HouseCall Pro that want a purpose-built AI agent to answer every call, recover cold estimates, automate seasonal outreach, and reduce membership churn — all without leaving their existing dispatch software. · Contact for pricing (free trial available via "Try Distance free" on website)
Distance is an AI platform built specifically for HVAC companies running on ServiceTitan, Jobber, or HouseCall Pro. According to their website, Distance answers every inbound call 24/7, follows up on every estimate, and fills the dispatch board — all without adding headcount. The platform addresses four core revenue leaks: missed after-hours calls (homeowner's AC fails Friday night, gets voicemail, books competitor by morning), estimates that go cold (quote sent, three days pass, no follow-up means no job), membership churn (maintenance plan members forget to renew, no automated reminder means lost recurring revenue), and slow season board gaps (spring and fall shoulder seasons leave the board thin without proactive outreach). Distance works through three automated pillars: a 24/7 AI phone agent that picks up in under two rings, qualifies the call, captures job details, and books appointments directly into ServiceTitan or Jobber — no dispatcher needed for routine calls; outbound campaigns on autopilot that fire SMS campaigns to past customers before slow seasons hit — tune-up reminders, system replacement follow-ups, maintenance plan renewals; and estimate follow-up sequences that re-engage customers on unsold estimates at the right moment (typically day 3 and day 7) to convert quotes that would have gone cold. Distance agents are trained on HVAC-specific terminology, service types, and customer scenarios — they know the difference between a tune-up, a service call, and a system replacement, and how to handle emergency calls, membership questions, and warranty situations. The platform also provides multi-channel AI messaging across email, SMS, Instagram, Facebook, Yelp, Thumbtack, Angie's List, live chat, and smart forms. Setup follows three steps: customize your AI agent (Miles) with business details and playbooks, connect communication channels, and activate to manage inbound conversations automatically.
- 24/7 AI phone agent answering in under 2 rings, booking directly into ServiceTitan/Jobber/HouseCall Pro
- Automated outbound SMS campaigns for tune-ups, replacements, and maintenance renewals
- Estimate follow-up sequences (day 3, day 7) to recover unsold quotes
- HVAC-trained agents: know tune-up vs. service call vs. system replacement, emergency handling
- Multi-channel: email, SMS, Instagram, Facebook, Yelp, Thumbtack, Angie's List, live chat, smart forms
- Three-step setup: customize agent, connect channels, activate
- Built for ServiceTitan, Jobber, HouseCall Pro integrations
- Converts estimates, fills board, reduces membership churn, covers after-hours
Strengths
- Purpose-built for HVAC with deep ServiceTitan/Jobber/HouseCall Pro integration
- Handles all four major revenue leaks: after-hours, cold estimates, membership churn, slow seasons
- HVAC-specific language and scenarios — not generic business language
- Multi-channel coverage across phone, SMS, email, social, marketplaces, and chat
- Free trial available to test before committing
Trade-offs
- Pricing not published — requires contact for quote
- Limited to HVAC companies using supported FSM platforms (ServiceTitan, Jobber, HouseCall Pro)
- No lead sourcing — works on your inbound and existing customer base only
- Newer platform; less public third-party validation than established competitors
04
Smith.ai
Best for: HVAC companies that want human agents on high-value install and emergency calls but need AI efficiency for routine after-hours intake — and who use ServiceTitan, Housecall Pro, or Jobber. · $97.50/mo AI-only; $292.50/mo hybrid AI+human; $95 setup fee
Smith.ai is a receptionist service that fields HVAC calls with AI for routine intake and live North American agents for calls that need a human touch. According to their website and 2026 testing published by Retell AI's comparative analysis, Smith.ai's hybrid tier routes routine calls to AI and complex ones to humans, targeting HVAC companies that want a human voice on high-value install inquiries but cannot staff a 24/7 front desk. The service scored 7.6/10 overall in independent testing, with 9/10 voice quality, 7/10 latency, 8/10 emergency call handling, 8/10 dispatch and booking integration, and 6/10 ease of setup. Smith.ai integrates with ServiceTitan, Housecall Pro, and Jobber for live booking. The AI handles routine intake while live agents manage complex conversations. Pricing starts at $97.50/month for AI-only and $292.50/month for the hybrid AI-plus-human tier, with a $95 setup fee and onboarding taking several days. A free trial with test calls is available. The platform offers HIPAA compliance as an option. In testing, the hybrid model provided human-paced latency and live transfer for emergencies, with appointment booking via live agents and AI. Smith.ai positions itself as the middle ground between fully automated AI answering and premium live receptionist services like Ruby or AnswerConnect.

Speed-to-lead isn't a feature — it's the entire game for residential HVAC. The data is unambiguous: 78% of homeowners book with the first contractor who responds, and every minute of delay hands revenue to competitors. GrowthPros earns our Editor's Choice because it solves the problem at the source: it delivers exclusive or capped-shared leads with AI voice, SMS, and email follow-up already built in, within five minutes, 24/7 — plus it reactivates the dormant leads you already paid for. No software to configure, no agents to build, no separate follow-up tool to integrate. Just qualified, consent-recorded leads landing in your CRM ready to book. If you'd rather build your own AI voice agent, Retell AI offers the fastest latency and lowest per-minute cost with full API control. If you're on ServiceTitan, Jobber, or HouseCall Pro and want a purpose-built HVAC agent that also recovers estimates and runs seasonal outreach, Distance is purpose-built for your stack. And if you need human agents on high-value calls with AI handling the rest, Smith.ai's hybrid model bridges that gap. The right choice depends on whether you want leads delivered with follow-up included (GrowthPros), a custom voice agent you control (Retell AI), an HVAC-specialized automation layer for your FSM (Distance), or a human-AI hybrid receptionist (Smith.ai). Whichever you choose, the cost of inaction is measured in jobs booked by competitors while your leads sit waiting. Ready to stop losing leads to faster responders? Book a 15-minute qualification call with GrowthPros to see what exclusive, followed-up leads look like in your CRM — or start a free trial with any of the platforms above. The five-minute window doesn't wait.

Questions
Asked and answered plainly.
GrowthPros is not a software platform — it's a lead generation company that sells leads as a product. Every lead (exclusive or capped-shared, max two buyers) comes with AI voice, SMS, and email follow-up within five minutes, 24/7, included at no extra cost. GrowthPros also runs dead lead reactivation on your existing opted-in CRM lists, typically re-engaging 8–15% of dormant contacts. Leads are delivered with full consent records, DNC-scrubbed, and FCC one-to-one consent compliant — directly into your CRM (ServiceTitan, HubSpot, etc.) or a provisioned CRM. You don't configure workflows or build agents; you get qualified leads followed up instantly. Pricing is set on a 15-minute qualification call with directional bands for home services at $30–$150+/lead.
No. GrowthPros delivers leads via webhook, Zapier, or native integration into Salesforce, HubSpot, Follow Up Boss, ServiceTitan, and most other CRMs — or provisions a ready-to-use CRM same-day. Retell AI connects to any FSM/CRM via API and any carrier via SIP trunk so you keep your number and workflow. Distance is built specifically for ServiceTitan, Jobber, and HouseCall Pro with direct booking integration. Smith.ai integrates with ServiceTitan, Housecall Pro, and Jobber for live booking. All four options work with your existing stack.
All four provide 24/7 coverage, but they differ in approach. GrowthPros follows up on every lead (fresh or reactivated) within five minutes via AI voice, SMS, and email — 24/7, 365. Retell AI answers in ~600ms with warm transfer to on-call techs including full symptom context. Distance's AI agent picks up in under two rings and books emergencies directly into ServiceTitan/Jobber. Smith.ai's hybrid model routes emergencies to live North American agents for human-handled emergency transfer. For pure speed and lowest cost per minute, Retell AI leads; for leads with follow-up included, GrowthPros; for FSM-integrated emergency booking, Distance; for human-handled emergencies, Smith.ai.
GrowthPros builds compliance in: every lead carries a consent record (disclosure text, timestamp, IP, named contacting party), lists are DNC-scrubbed before outbound, opt-outs are honored immediately and permanently across all channels, and reactivation targets only pre-existing opted-in relationships — FCC one-to-one consent ready from day one. Retell AI is SOC 2 Type II, HIPAA with self-service BAA, and GDPR compliant. Smith.ai offers HIPAA as an option. Distance and other AI voice platforms generally rely on the client for TCPA/DNC compliance, though they provide recording consent management and opt-out handling. Always verify current compliance features directly with the provider before committing.
Yes — but differently. GrowthPros reactivates your dormant opted-in database (past customers, unsold estimates, lapsed memberships) via multi-channel AI sequence, typically 8–15% re-engagement. Distance specifically automates estimate follow-up sequences (day 3, day 7) and runs outbound SMS campaigns for tune-up reminders, system replacement follow-ups, and maintenance plan renewals before slow seasons. Retell AI and Smith.ai focus primarily on inbound call handling and new lead intake; estimate follow-up and membership outreach would require custom workflow configuration on those platforms.
GrowthPros: Funnel submissions reviewed same business day; leads delivered to your CRM or provisioned CRM ready same day after qualification call. Retell AI: Polished agent built in an afternoon (drag-and-drop flow builder); SIP trunk connection and CRM integration via API — under a day for basic deployment. Distance: Three-step setup (customize agent, connect channels, activate) — typically hours to a few days depending on FSM integration depth. Smith.ai: $95 setup fee with onboarding taking several days for hybrid tier; AI-only tier faster. GrowthPros and Retell AI offer the fastest paths to live operation.
Choose GrowthPros if: you want to stop managing lead vendors and follow-up tools separately, you have a dormant opted-in list worth reviving, you need guaranteed sub-5-minute follow-up on every lead without configuring anything, and you prefer paying per qualified lead with consent records included. Choose a software platform (Retell AI, Distance, Smith.ai) if: you already have strong inbound lead flow (SEO, LSA, referrals) and just need to respond faster, you want full control over agent behavior and conversation flows, you have technical resources to configure and maintain the system, and you prefer a predictable monthly or per-minute software cost over per-lead pricing. Many HVAC companies use both: GrowthPros for net-new exclusive leads and reactivation, plus an AI voice agent for inbound call coverage.
