Comparison
GreeterHub vs Smith.ai
GreeterHub and Smith.ai both answer calls and book jobs, and both offer an AI receptionist. The difference for an HVAC shop: GreeterHub is one purely-AI receptionist, trained for HVAC, that transfers to your own on-call team. Smith.ai is a broad, multi-industry service whose AI Receptionist — even on its cheapest tier — is "backed by 500+ live agents," and whose best per-call rates require an annual contract started through a sales call.
GreeterHub does more than answer the phone — it's an AI office manager that books jobs, syncs to your CRM, and routes after-hours emergencies, not just a receptionist that takes a message.

When GreeterHub is the better fit
- You run an HVAC shop and want intake trained for your trade — no-heat triage, AC-not-cooling, refrigerant, panel/permit logic.
- You'd rather escalations go to your own on-call team than to a third-party agent pool — no call center between your caller and your shop.
- You want a flat monthly plan with included calls and low overage ($1.00–$1.50/call), month-to-month — no annual contract to get a fair rate.
- You want to hear it before you buy — call the live demo and ask it what your customers would ask.
When Smith.ai is the better fit
- You want trained human receptionists in the mix — Smith.ai backs even its AI tiers with its own 500+ live agents, and sells a full human Virtual Receptionist product alongside.
- You're not in the trades — Smith.ai is built horizontally for every industry, with a long track record.
- You want one vendor to span AI and full human answering as your needs change.
- You're comfortable with an annual contract and a sales call to unlock the best per-call rates.
What to look for in an AI receptionist
If you're weighing an AI receptionist for an HVAC shop against a broad, multi-industry answering service, these are the questions that matter most.
Is it trained for your trade, or general-purpose?
An agent that knows no-heat triage, AC-not-cooling, and refrigerant questions books the right job and asks the right follow-ups. A horizontal service spread across every industry has to be configured toward HVAC.
Is the AI really AI — and who handles escalations?
Some "AI" products still sit on a third-party human agent pool (Smith.ai's AI tiers are "backed by 500+ live agents"). GreeterHub is pure AI that transfers to your own on-call team by rules you set — no third-party call center, and no per-interaction cost for someone else's agents.
What does it cost once you go over, and is there a contract?
Look past the headline tier at the overage and the terms. Smith.ai self-service charges $2.40/call over your bucket and expires unused calls monthly; its best rates need an annual contract. GreeterHub is month-to-month with included calls and $1.00–$1.50/call overage.
Can you hear it before you buy?
A public demo number lets you call and stress-test it in 60 seconds. A sales-gated evaluation means you commit before you hear how it handles your callers.
