HVAC call-handling glossary
The vocabulary HVAC offices, answering services and AI receptionist vendors use, defined plainly and linked to the checklists and guides where each term matters.
Vendors in this market use overlapping words for similar things — "AI CSR", "virtual receptionist", "answering service" — and sometimes the same word for different things. These definitions are how the terms are used on this site. Jump to: Call handling · Handoffs and follow-up · Call types · Roles and measures · Operations and buying.
Call handling
- Intake
- The structured set of questions asked on an inbound call so the next person can act without calling the customer back. Call-intake checklists →
- Triage
- Sorting calls by urgency using criteria the company decides in advance, so urgent calls are handled first. Triage by the person answering is only as good as the written rules behind it. Proposed urgent-call escalation →
- Priority tiers
- Named urgency levels — for example emergency, replacement or install, and maintenance — that decide booking order when capacity is short. Avoca publicly describes a P1/P2/P3 version. Peak-season surge plan →
- Warm transfer
- Connecting a caller to a person while passing them a short summary first, so the caller does not have to repeat themselves. Warm transfer handoff →
- Cold transfer
- Putting a caller through to another person with no context passed along. Simpler than a warm transfer, but the caller usually has to start again.
- Overflow answering
- Backup coverage that picks up only when in-house lines are busy or unanswered after a set number of rings. Proposed overflow coverage →
- After-hours answering
- Coverage for calls outside posted business hours: nights, weekends and holidays. Overnight and weekend plan →
- IVR
- Interactive voice response: a phone menu such as 'press 1 for scheduling'. Useful for simple routing; frustrating when callers cannot find their option.
- Spam and robocall screening
- Filtering unwanted calls before they reach staff or create callback tasks.
- Bilingual answering
- Handling calls in more than one language — most often English and Spanish among the vendors we reviewed.
Handoffs and follow-up
- Dispatch handoff
- The information passed from whoever answered a call to the person who will schedule or send a technician. Dispatch board handoff →
- On-call technician
- The technician designated, on a rotation the company sets, to receive urgent calls outside normal hours. On-call technician handoff →
- Comfort advisor
- A common HVAC title for the salesperson who visits homes to recommend and quote replacement equipment. Sometimes called an in-home sales advisor. Comfort advisor handoff →
- Callback queue
- The list of callers who need a person to call them back, each with a reason, an owner and a due time. Callback queue handoff →
- Call summary
- A short written record of who called, why, what was captured, what the caller was told and who owns the next step. Proposed call summaries →
- Call outcome (disposition)
- The single result recorded for a call from a short fixed list — for example job request created, handed to a person, callback owed, information only, not a customer call or incomplete. Proposed call summaries →
- Missed-call follow-up
- A defined response to calls that were not answered, such as a callback task or a single approved text. Proposed missed-call follow-up →
- Abandoned call
- A call where the caller hung up before anyone answered, often while on hold. Most phone systems report these separately from unanswered calls. Measuring missed calls →
Call types
- No-heat call
- A caller reporting that heating is not working. Companies commonly treat it as urgent under conditions they define. No-heat checklist →
- No-cool call
- A caller reporting that air conditioning is not cooling. Urgency depends on the company's rules and the caller's situation. No-cooling checklist →
- Tune-up
- A scheduled seasonal maintenance visit for heating or cooling equipment. Tune-up checklist →
- Replacement or install lead
- A caller asking about new equipment; usually routed to a comfort advisor rather than the service board. Replacement estimate checklist →
- Warranty question
- A caller asking whether equipment or earlier work is covered. The answer needs company records and policy, not guesswork. Warranty question checklist →
- Safety-sensitive call
- A call mentioning a gas odor, carbon monoxide alarm, burning smell, smoke or similar. The company's written procedure governs the response; the person or system answering should not diagnose. Safety-sensitive procedure →
- Property manager or tenant call
- A call from someone who is not the equipment owner. Access, authorisation and who pays must be captured. Property manager and tenant checklist →
- Commercial service call
- A call about a business or multi-unit property, often involving site contacts, access windows and purchase orders. Commercial service checklist →
Roles and measures
- CSR (customer service representative)
- The person who answers customer calls, takes intake and books work. In HVAC offices the CSR role often overlaps with receptionist and, in small companies, dispatcher. Hire in-house or use a service? →
- Dispatcher
- The person who manages the schedule board: assigns jobs to technicians, fits in urgent work and keeps customers informed of arrival times. Dispatch board handoff →
- AI CSR or AI receptionist
- Software that answers calls in conversation, captures intake and may book or route calls. Vendors use both names; what each product actually does varies and should be tested. AI vs live answering →
- Booking rate
- Of callers who wanted service and could have been booked, the share who were. Definitions of which calls count vary, so compare only numbers measured the same way. HVAC answering service guide →
- Abandonment rate
- The share of callers who hung up before reaching anyone, usually while waiting or on hold, as reported by your phone system. Measuring missed calls →
- Escalation acknowledgement
- Confirmation from the person contacted about an urgent call that they have received it and are acting. Without it, an escalation may silently fail. Proposed urgent-call escalation →
Operations and buying
- Service area
- The towns or zip codes a company serves; used to decide whether a caller can be booked.
- Maintenance agreement
- A recurring service plan, often sold as a membership, that can change priority, pricing or scheduling for the customer who holds it. Plan member checklist →
- Live capacity
- The real, current availability on the dispatch board, as opposed to fixed booking windows set in advance. Proposed overflow coverage →
- Field service management (FSM) software
- Software such as ServiceTitan, Housecall Pro, Jobber or FieldEdge in which jobs, customers and technicians are managed. Compatibility questions →
- Per-minute billing
- Answering-service pricing by minutes of call time. Costs rise with call volume, which matters in HVAC's seasonal peaks. Pricing models guide →
- Per-call or per-customer billing
- Pricing by number of calls or unique callers rather than by minutes.
- Hybrid AI and human answering
- A model in which software handles routine calls and people take escalations and sensitive calls. AI vs live answering →
- Shoulder season
- The spring and autumn periods between peak heating and cooling demand, when call mix shifts toward maintenance and planned work. Shoulder-season plan →
