Short answer
An HVAC AI receptionist is best for repeatable coverage gaps: after-hours calls, overflow, missed calls, appointment intake, and estimate follow-up. A human CSR is best for judgement-heavy calls, relationship management, and complex customer situations.
Fastest lead path
Forward missed calls, after-hours calls, and overflow calls first. Those windows usually produce the quickest recovered opportunities because the lead already exists.
